Deep sleep is the most refreshing sleep, as subjectively described by people after they wake up. Unfortunately, the older we get the less deep sleep we get.. Deep sleep is stage 3 sleep (or stages 3 and 4 under the classification that includes a stage 4). On an EEG the voltage difference patterns over time show up as delta waves. This is also called slow-wave sleep to distinguish it from the fast-wave sleep of Stage 2. Deep, or heavy sleep, is so-called because it is more difficult to awaken people in this stage than in light sleep, and if woken suddenly from this stage, people have sleep inertia. People in deep sleep are less apt to wake in response to external stimuli than those in light sleep Sleepers in deep sleep move their bodies less than in light sleep, although more than in REM sleep. The restlessness of some sleepers that results in tangled-up bedding occurs in light sleep.. Deep sleep is a time of accelerated tissue repair. In growing children, this is a time of physical growth. Human ...
OBJECTIVES: To define normal values for total sleep time, sleep latency, sleep efficiency, sleep stages and sleeping positions in women and to investigate how sleep is affected by age, obesity, sleep apnea, smoking, alcohol dependency and hypertension. METHODS: In a population-based study, 400 Swedish women aged 20-70 years with over-sampling of snorers were investigated using overnight in-home polysomnography. All results are weighted. RESULTS: The mean normal total sleep time was 392 min, sleep latency 22 min and sleep efficiency 82%. Women spent 31 min in sleep stage 1, 244 min in stage 2, 41 min in stage 3/4 and 76 min in rapid eye movement (REM) sleep. They spent 41% of their sleep time in the supine position, 50% in the lateral position and 9% in the prone position. Multivariate analyses revealed that sleep efficiency was lower in older women and in women with hypertension. Sleep latency was short in women with severe sleep apnea and long in smokers, alcohol-dependent and hypertensive ...

TY - JOUR. T1 - Poor sleep quality and obstructive sleep apnea in patients with GERD and Barretts esophagus. AU - Vela, M. F.. AU - Kramer, J. R.. AU - Richardson, P. A.. AU - Dodge, R.. AU - El-Serag, H. B.. PY - 2014/3/1. Y1 - 2014/3/1. N2 - Background: Gastroesophageal reflux disease (GERD) reduces sleep quality. Whether Barretts esophagus (BE) affects sleep differently is unknown. Obstructive sleep apnea (OSA) often coexists with GERD and may disrupt sleep; whether GERD reduces sleep quality independently of OSA is unknown. Our aims were to compare the effect of GERD and BE on sleep quality, and assess the impact of OSA on this association. Methods: Validated questionnaires for GERD symptoms, sleep quality, and OSA risk were prospectively administered to subjects undergoing upper endoscopy. GERD was defined by erosive esophagitis and/or reflux symptoms ,1/week. BE was defined histologically. Controls had normal endoscopy and were asymptomatic. Poor sleep quality was defined by a Pittsburgh ...
A Sleep Stage is one of five parts or stages of the sleep cycle based on the type of brain activity that occurs during the stage. In mammals and birds, sleep is divided into two broad types: rapid eye movement (REM) and non-rapid eye movement (NREM or non-REM) sleep. Each type has a distinct set of associated physiological, neurological, and psychological features. The American Academy of Sleep Medicine (AASM) further divides NREM into three stages: N1, N2, and N3, the last of which is also called delta sleep or slow-wave sleep (SWS). Sleep proceeds in cycles of REM and NREM, the order normally being N1 → N2 → N3 → N2 → REM. There is a greater amount of deep sleep (stage N3) earlier in the sleep cycle, while the proportion of REM sleep increases later in the sleep cycle and just before natural awakening. The stages of sleep were first described in 1937 by Alfred Lee Loomis and his co-workers, who separated the different electroencephalography (EEG) features of sleep into five levels (A ...
We investigated the associations between sleep duration and CKD in a Korean adult population. Herein, sleeping more than 9 hours was significantly associated with CKD in women; however, sleep duration was not significantly associated with CKD in men.. In recent decades, the average sleep duration in most individuals has reduced, and many studies have investigated shorter sleep durations and their effects on health. In particular, the average sleep duration of Koreans was 7 hours and 49 minutes per day, which was the lowest among 18 OECD (Organisation for Economic Co-operation and Development) member countries [19]. Notwithstanding, epidemiological evidence of associations between sleep duration and CKD is insufficient. Previous studies reported that sleeping less than 5 hours was associated with proteinuria in the Japanese population [8,20] and higher risk of CKD among the shift workers [13]. More recently, an increasing number of studies have linked prolonged sleep duration with poor health ...
Some of the major health benefits of good sleep are as below -. A proper sleep is necessary for good eye sight (vision). If you do not sleep properly at night then you will have defective vision. Emaciation, weakness, impotency, sterility, lack of knowledge and death may be result of poor sleep. A good night sleep strengthens the presence of your mind and consciousness. It makes you feel energized and physically more alert. It enhances your memory and learning capacity. Getting adequate sleep will help you remember and process things better. Good sleep strengthens your immune system and makes you less prone to various illnesses. It reduces stress, tension and anxiety. A proper sleep allows your body to rest and relax. When your body lacks sleep it goes into a state of stress. Good night sleep helps to lose weight. Sleep deficient individuals are more likely to be overweight or obese. Good night sleep keeps your heart healthy. Lack of proper sleep has been associated with increasing blood ...

Sleep is under homeostatic control, but the mechanisms that sense sleep need and correct sleep deficits remain unknown. Here, we report that sleep-promoting neurons with projections to the dorsal fan-shaped body (FB) form the output arm of Drosophilas sleep homeostat. Homeostatic sleep control requires the Rho-GTPase-activating protein encoded by the crossveinless-c (cv-c) gene in order to transduce sleep pressure into increased electrical excitability of dorsal FB neurons. cv-c mutants exhibit decreased sleep time, diminished sleep rebound, and memory deficits comparable to those after sleep loss. Targeted ablation and rescue of Cv-c in sleep-control neurons of the dorsal FB impair and restore, respectively, normal sleep patterns. Sleep deprivation increases the excitability of dorsal FB neurons, but this homeostatic adjustment is disrupted in short-sleeping cv-c mutants. Sleep pressure thus shifts the input-output function of sleep-promoting neurons toward heightened activity by modulating ion
STUDY OBJECTIVES: Patients with chronic kidney disease (CKD) often report poor sleep quality, but they commonly exhibit OSA. The aim of this study was to evaluate the influence of OSA severity and of estimated glomerular filtration rate impairment on objective sleep quality in nondialyzed patients with CKD, defined as an estimated glomerular filtration rate <60 mL/min/1.73m². METHODS: Polysomnographic sleep characteristics were compared between patients with (n = 430) and without CKD (n = 6,639) in the European Sleep Apnea Database cohort. Comparisons were repeated in 375 patients with CKD and 375 control patients without CKD matched for sleep center, age, sex, and AHI, and in 310 matched CKD and non-CKD patients without psychiatric disturbances. RESULTS: Among all patients with and without CKD, total sleep time was similar but sleep stage N1 (median 8.7% [IQR 4.8-18.0] vs 6.7% [3.6-12.7], respectively) and sleep stage R (12.6% [6.8-17.7] vs 14.2% [8.8-19.8], respectively) significantly ...
Objective: We investigated sex differences in sleep and examined the association between objectively-measured sleep characteristics and weight gain among 54 black students at a historically black university in spring 2018. Methods: Participants wore a wearable tracker (Fitbit Alta) for an average of 68 days of sleep over the spring semester and 5.5 days of sleep over the spring break. They also completed a questionnaire. Results: Average sleep duration was 6 hours 35 minutes. More women had short sleep (< 7 hours / night) than men (92.1% vs 43.8%; p < .001). Women had shorter sleep (6 hours 24 minutes vs 7 hours 1 minute; p = .003), shorter naps (2 hours 4 minutes vs 2 hours 30 minutes; p = .043), and lower sleep efficiency (93.0% vs 94.1%; p = .048) than men. More women than men experienced weight gain (79.0% vs 68.8%, p < .05). We found an inverse relationship between sleep duration and weight gain in both sexes (r = -0.42, p < .05). Conclusions: Appropriate sleep and weight management should ...
The amount of sleep people require depends on many factors, including age, but experts agree that most adults need 7 to 8 hours of sleep a night. People who sleep for shorter or longer amounts of time may be at risk of developing memory problems, heart disease, obesity, and diabetes. The duration and timing of sleep are regulated by an interaction between the circadian pacemaker, or biological clock, and the sleep homeostat, which is an internal account of the amount of sleep a person has received recently. It is unknown whether there is a biological or genetic basis for the amount of sleep a person needs. This inpatient study will examine two extreme sleep groups: short sleepers who sleep 6.5 or less hours a night and long sleepers who sleep 9 or more hours a night. Participants will be exposed to identical sleep opportunities and living conditions. Using hormone analysis to examine participants circadian rhythms, researchers will evaluate the biological differences that people undergo during ...
DISCUSSION. The present study confirmed that poorer subjective sleep quality is related to greater unstimulated sexual arousal, and that this relation was mostly driven by men with higher T levels and women with higher T levels not taking oral contraception. These findings extend previous ones showing that 1) severity of womens subjective sleep problems correlated with greater fantasy-induced subjective sexual arousal25, 2) perceived genital arousal was greater, when the duration of sleep was shorter in the previous night26, and 3) sleep deprivation in men increased erections in response to erotica23 and visual attention to images of women24. Our findings are also consistent with studies in male rats showing that unstimulated erections are facilitated by REM sleep deprivation11,12, a consequence of general sleep deprivation.. As predicted, severity of sleep problems correlated with unstimulated arousal only in the male and female groups with higher T levels. The facilitating role of T in ...

Our experiments aimed to investigate whether different degrees of mental activity have a distinct effect on recovery processes during subsequent sleep. Sleep EEGs of 13 subjects, experiencing different degrees of mental activity, were scored visually. Also, the amount of SWA in the sleep EEG was calculated. The results indicate that light and heavy mental activity do not differentially affect sleep stages except for wakefulness after sleep onset. Subjects were less often awake shortly after sleep onset following heavy workload than after light mental activity. However, SWA, an indicator of sleep depth, did not reveal any difference between the light (A) and heavy condition (B). Neither the total amount of SWA expressed during the night, nor the amount of SWA in the first 120 min of NREM sleep, when recovery processes supposedly peak, showed a difference between the conditions. Even when the time course of SWA during sleep was studied in detail, the nights following light and heavy mental ...
We suggest patients to do overnight sleep studies to diagnose sleep disorders such as sleep apnoea. The sleep study will determine the level of severity of sleep apnoea.. Other sleep disorders can be diagnosed through sleep study such as restless leg syndrome and insomnia.. The sleep study can be done in the hospital or in the home. The home sleep study gives patients the comfort of sleeping in a natural environment. However, in some complex cases we suggest the patient to do an overnight sleep test in a hospital.. After analysing the data by a sleep physician, based on the degree of sleep apnea we suggest the sleep appliance or CPAP machine.. ...

Our study demonstrated that 53 % of patients with COPD in our cohort had poor sleep quality (PSQI score , 5). A high prevalence of poor sleep quality in patients with COPD has been reported in previous studies [1, 2, 8]. In a recent real-world study, 78 % of patients with COPD reported night time disturbances as measured by the Jenkins Sleep Questionnaire [21]. In a telephone study, Ohayon reported COPD subjects had higher insomnia symptoms than non-COPD subjects (48.1 versus 27.6 % respectively) [22].. Our study also confirmed sleep disturbances, as well as cough and dyspnea, as major concerns in patients with COPD. Some researchers suggest that poor sleep quality might result in cognitive dysfunction, depression, anxiety, poor survival and poor quality of life [7]. Determining which factors are associated with sleep disturbances in patients with COPD may improve their treatment strategy.. A high prevalence of sleep symptoms among patients with COPD was discovered approximately thirty years ago ...

Genes may play a significant role in how much sleep we need. Scientists have identified several genes involved with sleep and sleep disorders, including genes that control the excitability of neurons, and clock genes such as Per, tim, and Cry that influence our circadian rhythms and the timing of sleep. Genome-wide association studies have identified sites on various chromosomes that increase our susceptibility to sleep disorders. Also, different genes have been identified with such sleep disorders as familial advanced sleep-phase disorder, narcolepsy, and restless legs syndrome. Some of the genes expressed in the cerebral cortex and other brain areas change their level of expression between sleep and wake. Several genetic models-including the worm, fruit fly, and zebrafish-are helping scientists to identify molecular mechanisms and genetic variants involved in normal sleep and sleep disorders. Additional research will provide better understand of inherited sleep patterns and risks of ...

Monitoring their sleeping patterns, researchers identified an increase in the duration and continuity of REM sleep and specific brain oscillations characteristic of REM sleep, whereas deep sleep, or non-REM sleep, did not change. The changes in REM sleep were very tightly linked to deficiency in the regulation of the stress hormone corticosterone. Mild stress also caused changes in gene expression in the brain. The first and most distinct consequence of daily mild stress is an increase in rapid-eye-movement (REM) sleep, a new study in the journal PNAS reports. The research also demonstrated that this increase is associated with genes involved in cell death and survival. REM sleep, also known as paradoxical sleep, is the sleep state during which we have most of our dreams and is involved in the regulation of emotions and memory consolidation. REM sleep disturbances are common in mood disorders, such as depression. However, little was known about how sleep changes are linked to molecular changes in the

Background A scientific understanding of the effects of seasonal changes on sleep duration and sleep problems such as insomnia and hypersomnia has yet to be elucidated; however, such an understanding could aid the establishment of an optimal sleep hygiene program to treat such problems. Methods We investigated the effects of seasonal changes on sleep duration and sleep problems in Japanese community residents. Data on 1,388 individuals aged 15-89 years who participated in the Survey of Seasonal Variations in Food Intakes conducted by the National Institute of Health and Nutrition of Japan (2004-2007) were analyzed. Participants completed a questionnaire including items on sleep duration and sleep problems (difficulty initiating sleep [DIS], difficulty maintaining sleep [DMS]/early morning awakening [EMA], and excessive daytime sleepiness [EDS]). Data were prospectively collected at four time points (spring, summer, fall, and winter). Results Seasonal changes in sleep duration were found, with the
Infant and maternal sleep in the postpartum are related, and influenced by the mothers understanding of infant sleep behavior, the environmental and social cues for sleep presented to the infant, development of the infants sleep physiology, maternal sleep habits and behaviors, and maternal feelings related to her sleep and her babys sleep. These factors may be modifiable through the use of behavioral-educational interventions. A randomized controlled trial design will be used to answer whether a behavioral-educational sleep intervention and support from a nurse in the immediate postpartum improves maternal and infant sleep 6 weeks later. Sleep-wake patterns will be analyzed through the use of actigraphy, a wristwatch-like device that measures sleep-wake activity. This is a pilot study which will test the usefulness and practicality of this type of program, so that a larger scale study can be developed ...
There are two ways to conduct a sleep study in order to obtain a diagnosis of sleep disordered breathing. Either a study done at a sleep lab or home sleep testing. A sleep study can be recommended by either a physician or in my case a dentist. Sleep studies are recommended after an interview with a patient that has yielded a high pre-test probability of having some form of sleep disorded breathing. Risk factors to name a few are as follows: Daytime sleepiness, disrupted sleep, habitual snoring, obesity, observed chocking and gasping, high blood pressure, acid reflux during sleep. These listed symptoms are some but not all of the negative health effects of sleep apnea. Outside of serious health conditions home sleep testing is appropriate for most people. If you would like to undergo a sleep study in the privacy of your home give my office a call today and be on your way to quality sleep and a healthier longer life. ...
Sleep plays an integral role in maintaining physical and mental health. Not getting enough quality sleep can interfere with a persons ability to store newly learned information, potentially leading to a negative impact on academic performance. In addition, sleep deprivation is associated with daytime sleepiness, depressed mood, impaired concentration and memory, and a weakened immune system. Practicing healthy sleep habits (also known as good sleep hygiene) can make a big difference in a persons quality of life. A considerable amount of research has demonstrated that practicing sleep hygiene strategies such as the ones listed below, improves sleep quality and prevents sleep disturbances among university students.. ...
Sleep is an essential part of good health, as important as a balanced diet and regular exercise. Unfortunately, most Americans view sleep as a waste of time. We as a society don t place enough value on sleep, says Steve Gardner, director of marketing for the Sleep Wellness Institute and executive director of the Reggie White Sleep Disorders Foundation.. Dr. Rose Franco, associate director of the Sleep Disorders Program at the Medical College of Wisconsin, says people don t make sleep a priority. We need to do a better job of making time to sleep, she says.. A study by the National Sleep Foundation indicates that 60 to 70 percent of the population in the United States doesn t get enough sleep at night. Adults need seven to nine hours of sleep every night, but most people average just six and one-half hours. When you don t get enough sleep, your body develops a sleep debt one of the hardest debts to repay, Gardner says. It keeps accumulating and you feel more and more exhausted.. Although ...
The objective of the study was to investigate whether school-aged children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) experience greater sleep disturbance than do normally-developing children. Participants included 33 parents and their children with ADHD (mean age = 10.7 ± 1.7 years) and 33 parents and their children without ADHD (mean age = 10.7 ± 1.6 years). Both parents and their children completed sleep questionnaires developed to assess a number of sleep variables. Based on parental report, the Total Sleep Disturbance score was significantly greater for the ADHD group than for the comparison group. Parents indicated that children with ADHD had significantly more disturbed sleep than did children without ADHD on 8 of the 10 sleep subscales of the Sleep Questionnaire for Parents. These were: Bedtime Resistance, Morning Difficulty, Parasomnias/Other Sleep Disturbance, Restless Legs Syndrome, Sleep Anxiety/Transitioning, Sleep Duration/Quality, Sleep Hygiene, and Sleep Onset.
Change in Breathing Pattern. Many theories state that the periodic breathing pattern, common during sleep at high altitude, is a potential cause of sleep disturbances. Periodic breathing is a form of Cheyne-Stokes respiration and reflects changes in neural signaling due to hypoxia and alkalosis during sleep.4 Hypoxia is a respiratory stimulant while alkalosis is a respiratory depressant.4 This mixed signaling is the source of the altered breathing during non-REM sleep encountered at altitudes over 2500 m. The frequency of periodic breathing during sleep increases as the altitude increases.3,4,7. Decreased Sleep Efficiency Compared with sea level, several studies have depicted that sleep at higher altitude is characterized by decreased sleep efficiency, prolonged superficial stages of sleep, and reduced stages of deep sleep.12 The image below is a qualitative representation of sleep structure recorded at sea level and at high altitude. The area encircled by the outer line reflects the time in ...
This third one is what I study. The synaptic homeostasis hypothesis is this idea that during the day, we make all these connections with the world around us. It used to be like, Dont go over there-the lions live there now. Now its like, What did Barbara say to me in the office? These excitatory connections we make during the day result in the neurons in our brains getting overall higher activation. Then during the nighttime when we sleep, we have a downregulating process where the things that didnt really matter to your survival sink to the bottom, and the things that are most relevant to your survival rise to the top. What deep sleep does is all the neural processing, and what REM sleep [rapid-eye-movement sleep] and light sleep do is basically integrate that into your long-term personality and understanding of the world. ...
How sleep can balance your hormones.. Are you getting enough? Think you can survive on 5-6 hours? There is strong evidence to say that anything less than 7 hours will have a dramatic impact on your immune system and affect your amygdala (a section of the brain that is responsible for detecting fear and preparing for emergency events) which in turn will affect your cortisol levels, making you age more rapidly and making you gain weight and throw other hormones out of whack - and these are just some of the examples!. On a basic level we sleep in 90 minute cycles which run from REM (rapid eye movement) to light sleep to deep sleep, with deep sleep generally coming at the end of the cycle.. During our light sleep we fall into a slow mantra*, a rhymic flow of data processing and compartmentalizing. This stage is particularly important for those with high blood pressure.. The part of sleep that eluded me the most over the past year was deep sleep. I was falling well below the amount I needed to get ...
There is no question that a cocktail or a glass of wine is relaxing at the end of a long day. You might even think that drinking alcohol helps you sleep.. While it is true that alcohol has a sedative effect which promotes sleep. What you might not know is that if you drink alcohol to help you sleep, you will not only get less sleep, but the quality of your sleep is significantly diminished.. Alcohol Interrupts Normal Sleep Rhythms. In a report released in 2004 by Science Daily.com, medical researchers at Wake Forest University Baptist Medical Center in San Diego, California studied the relationship between alcohol consumption and sleep in order to find out why alcoholics who have quit drinking return to alcohol to help them sleep.. Researchers saw that while the sedative effects of alcohol promote sleep, in the second half of sleep cycles, the brain waves involved in normal sleep rhythms are disrupted, resulting in poor sleep quality . Furthermore, the brain eventually builds up a tolerance to ...

In this study, we developed techniques to examine the relationship between sleep/wake state and mean arterial pressure (MAP) in unrestrained, genetically identical mice (C57BL/6J; n = 9). The left common carotid artery was catheterized, and arterial blood gases were analyzed 24-48 h postsurgery to verify normal respiratory and metabolic function. The animals were then allowed to cycle naturally through sleep/wake states over a 3- to 4-h period while continuous polysomnography and arterial pressure measurements were made. The MAP decreased from quiet wakefulness to non-rapid-eye-movement sleep (9.8 ± 1.3 ...
This cohort study, including 1601 patients with CKD, revealed that short and long sleep duration (≤5.0 and ,8.0 hours) and poor sleep quality (PSQI global score ≥6) were significantly associated with higher incidence of ESKD. These results suggest that a quick assessment of self-reported sleep duration and sleep quality might be an easy and effective way to identify patients with CKD at high risk of ESKD. Advantages of this study included its prospective cohort design, the clinically relevant hard outcome of ESKD, and its large sample size (n=1601), which enabled us to perform statistically meaningful analyses to identify predictors of ESKD.. Although several cohort studies have reported that shorter sleep duration was associated with incidence of proteinuria (16) and GFR decline (17,18), mainly in subjects with normal kidney function, few studies have reported an association between sleep duration and incidence of ESKD. The Chronic Renal Insufficiency Cohort (CRIC) study, a cohort study of ...
This is the first study to examine the long-term outcomes of sleep problems in a community sample of infants, together with the long-term impact of a behavioral sleep intervention on infant sleep problems. Sleep problems were identified in approximately one third of the 3- to 4-year-old children surveyed, all of whom had had significant sleep problems as infants. These children at 3 to 4 years were more likely to need an adult to nurse them to sleep. They also had higher Internalizing and Externalizing Scores and Aggressive Behavior and Somatic Problems subscale scores of the CBCL than children without sleep problems. Their mothers had higher EPDS scores as well as difficulties with their partner undermining the management of their child. Despite this, the children and their families were generally functioning well, and 69% of mothers reported that their childs sleep problem had resolved from infancy. The resolution of sleep problems in children who had received an infant sleep intervention was ...
In collaboration with Dr. Tarja Porkka-Heiskanen, we tested the role of nitric oxide (NO) in sleep homeostasis by using in vivo microdialysis to administer compounds into the rat basal forebrain that increase or decrease concentrations of NO. Consistent with our hypothesis, we found that nitric oxide production is required for the production of NREM recovery sleep following sleep deprivation. However, using specific inhibitors of nitric oxide synthases, we found that iNOS rather than nNOS produced the nitric oxide involved in homeostatic sleep regulation. The generation of NREM recovery sleep was tightly associated with increases in adenosine levels in the BF: when adenosine concentration was not elevated, recovery sleep was not induced while all cases of recovery sleep induction were preceded by adenosine increases. These results suggest that the elevation of NO in the BF during prolonged wakefulness is a specific mechanism for producing NREM recovery sleep. We are now interested in the ...

Originally posted on The Saturday Evening Post. Getting a proper amount of sleep is important for maintaining good health. I sometimes have trouble sleeping, probably from that second glass of red wine at dinner and coffee afterwards. I usually fall asleep rapidly and then wake up three hours later and toss and turn, eventually falling back to sleep. My sleep pattern is not a healthy one, as recent evidence indicates.. In a study of 385,292 adult men and women initially free of cardiovascular disease in the United Kingdom, people whose sleep pattern was characterized by five factors below had about a third less risk of heart disease and stroke compared to those who reported none or only one of these healthy sleep patterns:. 1) being a morning person. 2) sleeping 7-8 hours per day. 3) never or rarely experiencing insomnia. 4) not snoring. 5) not experiencing frequent excessive daytime sleepiness. Healthy sleep behavior even reduced the risk of a genetic predisposition to heart disease for ...
Although the amount of sleep you get each day is important, other aspects of your sleep also contribute to your health and well-being. Good sleep quality is also essential. Signs of poor sleep quality include not feeling rested even after getting enough sleep, repeatedly waking up during the night, and experiencing symptoms of sleep disorders (such as snoring or gasping for air).

Study participants were 1,024 volunteers from the Wisconsin Sleep Cohort Study, a population-based longitudinal study of sleep disorders. Participants underwent nocturnal polysomnography and reported on their sleep habits through questionnaires and sleep diaries. Following polysomnography, morning, fasted blood samples were evaluated for serum leptin and ghrelin (two key opposing hormones in appetite regulation), adiponectin, insulin, glucose, and lipid profile. Relationships among these measures, BMI, and sleep duration (habitual and immediately prior to blood sampling) were examined using multiple variable regressions with control for confounding factors.. A U-shaped curvilinear association between sleep duration and BMI was observed. In persons sleeping less than 8 h (74.4% of the sample), increased BMI was proportional to decreased sleep. Short sleep was associated with low leptin (p for slope = 0.01), with a predicted 15.5% lower leptin for habitual sleep of 5 h versus 8 h, and high ghrelin ...
OBJECTIVE: Short and long sleep duration are associated with increased risk of clinical cardiovascular events, but the association between sleep duration and subclinical cardiovascular disease is not well established. We examined the association between sleep duration and sleep quality with coronary artery calcification (CAC) and with brachial-ankle pulse wave velocity (PWV) in a large sample of young and middle-aged asymptomatic adults. APPROACH AND RESULTS: We conducted a cross-sectional study of adult men and women who underwent a health checkup examination, including assessment of sleep duration and quality and coupled with either CAC (n=29 203) or brachial-ankle PWV (n=18 106). The multivariate-adjusted CAC score ratios (95% confidence interval) comparing sleep durations of /=9 hours with 7 hours of sleep were 1.50 (1.17- 1.93), 1.34 (1.10-1.63), 1.37 (0.99-1.89), and 1.72 (0.90-3.28), respectively (P for quadratic trend=0.002). The corresponding average differences in ...
Our understanding of the molecular mechanisms underlying sleep homeostasis is limited. We have taken a systematic approach to study neural signaling by the transmitter 5-hydroxytryptamine (5-HT) in drosophila. We have generated knockout and knockin lines for Trh, the 5-HT synthesizing enzyme and all five 5-HT receptors, making it possible for us to determine their expression patterns and to investigate their functional roles. Loss of the Trh, 5HT1a or 5HT2b gene decreased sleep time whereas loss of the Trh or 5HT2b gene diminished sleep rebound after sleep deprivation. 5HT2b expression in a small subset of, probably a single pair of, neurons in the dorsal fan-shaped body (dFB) is functionally essential: elimination of the 5HT2b gene from these neurons led to loss of sleep homeostasis. Genetic ablation of 5HT2b neurons in the dFB decreased sleep and impaired sleep homeostasis. Our results have shown that serotonergic signaling in specific neurons is required for the regulation of sleep ...
Sleep homeostasis depends on the length and quality (occurrence of stressful events, for instance) of the preceding waking time. Forced wakefulness (sleep deprivation or sleep restriction) is one of the main tools used for the understanding of mechanisms that play a role in homeostatic processes involved in sleep regulation and their interrelations. Interestingly, forced wakefulness for periods longer than 24 h activates stress response systems, whereas stressful events impact on sleep pattern. Hypothalamic peptides (CRH, prolactin and the CLIP/ACTH18-39) play an important role in the expression of stress-induced sleep effects, essentially by modulating REM sleep, which has been claimed to affect the organism resilience to the deleterious effects of stress. Some of the mechanisms involved in the generation and regulation of sleep and the main peptides/hypothalamic hormones involved in these responses will be discussed in this review.
Sleep Medicine is a relatively new field of medicine spanning multiple disciplines. The range of healthcare professionals involved in the management of sleep disorders includes Neurologists, Respiratory physicians, Psychiatrists, Psychologists, ENT surgeons, Sleep Technologists and Respiratory Therapists.. Sleep disorders are conditions occurring around and during sleep which disturb normal sleep. Sleep is an important time for rest and restoration of the mind and body. When sleep is disrupted, our health is impaired. Sleep disorders affect the brain and physical functioning, and often worsen existing conditions such as diabetes, high blood pressure, heart disease, stroke and depression. People who do not get enough sleep are also at risk of more frequent accidents, and poorer performance at school or work.. People at risk for sleep problems include those with irregular work and sleep schedules, poorly managed stress, depression and anxiety, chronic pain, and diseases of the brain such as ...

Sleep is an important factor in our health. Without the right amount of sleep, the body mechanisms fail to perform their functions due to fewer reactions of hormones leading to poorer health conditions as well as frequent illnesses. A maximum amount of 7 hours of sleep is needed four bodies to complete the 24-hour cycle.. An individual can go through stages of sleep such as mild sleep to deep sleep states, but in between the sleep cycles, there are sleep disorders than an individual might experience, yet be completely unaware of it. One of the most common talked sleep disorder that young adults and older persons face is the sleep Apnea sleep disorder than is followed with many other side effects in sleep duration as well as day to day life.. ...
TY - JOUR. T1 - Factor analysis of the pittsburgh sleep quality index in breast cancer survivors. AU - Otte, Julie L.. AU - Rand, Kevin L.. AU - Carpenter, Janet S.. AU - Russell, Kathleen M.. AU - Champion, Victoria L.. PY - 2013/3/1. Y1 - 2013/3/1. N2 - Context: Sleep is a significant problem in breast cancer survivors (BCS) and measured frequently using the Pittsburgh Sleep Quality Index (PSQI). Thus, it is important to evaluate its factor structure. The two-process model of sleep regulation was the theoretical framework for this study. Objectives: To perform a confirmatory factor analysis of the PSQI in BCS and compare results between African-American and Caucasian BCS. Methods: This was a secondary analysis of cross-sectional data using local and regional health care facilities and Eastern Cooperative Oncology Group referrals. The study included 1174 nondepressed BCS (90% Caucasian), with a mean age of 57 years and median PSQI global scores at the cutoff for poor sleep (median = 6.00, ...
Sleep quantity and quality are both important for optimal development and functioning during youth. Yet few studies have examined the effects of insomnia symptoms and objective short sleep duration on memory performance among adolescents and young adults. One-hundred and ninety participants (female: 61.6%) aged from 12 to 24 years completed this study. All participants underwent a clinical interview, a 7-day actigraphic assessment, a battery of self-report questionnaires and cognitive tests to assess working memory and episodic memory. Insomnia symptoms were defined as a score ≥ 9 on the Insomnia Severity Index, and objective short sleep duration was defined as average total sleep time less than 7 hr for those aged 12-17 years, and 6 hr for those aged 18 years and above as assessed by actigraphy. Insomnia symptoms were significantly associated with worse self-perceived memory (p | .05) and poorer performance on the digit span task (p | .01), but not the dual N-back task and verbal learning task. There
Gene targeted mice can be used as models to investigate the mechanisms underlying sleep regulation. Three commonly used background strains for gene targeting (129/Ola, 129/SvJ and C57BL/6J) were subjected to 4-h and 6-h sleep deprivation (SD), and their sleep and sleep EEG were continuously recorded. The two-process model of sleep regulation has predicted the time course of slow-wave activity (SWA) in nonREM sleep after several sleep-wake manipulations in humans and the rat [3] [9]. We tested the capacity of the model to predict SWA in nonREM sleep on the basis of the temporal organization of sleep in mice. The strains differed in the amount and distribution of sleep and the time course of SWA. After spontaneous waking episodes of 10-30 min as well as after SD, SWA was invariably increased. Simulations of the time course of SWA were successful for 129/SvJ and C57BL/6J, but were not satisfactory for 129/Ola. Since the time constants are assumed to reflect the dynamics of the physiological processes
A substantial body of literature supports the intuitive notion that a good nights sleep can facilitate human cognitive performance the next day. Deficits in attention, learning & memory, emotional reactivity, and higher-order cognitive processes, such as executive function and decision making, have all been documented following sleep disruption in humans. Thus, whilst numerous clinical and experimental studies link human sleep disturbance to cognitive deficits, attempts to develop valid and reliable rodent models of these phenomena are fewer, and relatively more recent. This review focuses primarily on the cognitive impairments produced by sleep disruption in rodent models of several human patterns of sleep loss/sleep disturbance. Though not an exclusive list, this review will focus on four specific types of sleep disturbance: total sleep deprivation, experimental sleep fragmentation, selective REM sleep deprivation, and chronic sleep restriction. The use of rodent models can provide greater ...
Sleep Apnea Screening. This month CNN.com had an article that was on screening for sleep apnea. The article discusses how sleep apnea cant usually be detected by doctors during routine office visits but screening from your dentist may help. Recent studies have shown that teeth grinding is a major indicator for obstructive sleep apnea. Dentists can screen for teeth grinding. The article clarifies that a dentist can tell you definitively if you grind your teeth or not but they do not diagnose sleep apnea. Medical specialists are the only medical providers who can officially diagnose and treat sleep apnea. The article highlights that sufferers of sleep apnea may never get the benefits of the deep sleep. Symptoms of untreated sleep apnea include feeling sleepy or tired during waking hours, grinding teeth and snoring. Sleep apnea is a condition that affects an estimated one in fifteen Americans, but often goes unnoticed. Sleep apnea can range from mild to severe. The most common sleep apnea is ...
Generally, poor sleep leads to lower pain thresholds and a lower pain threshold decreases sleep efficiency. Obstructive sleep apnea not only disrupts sleep but does so with repeated bursts of stress hormones and a drop in blood oxygen which can be quite significant.. Studies have shown a 55.4% prevalence of chronic widespread pain in patients with obstructive sleep apnea and a greater risk of chronic pain in female than in male patients. Female patients with obstructive sleep apnea and chronic pain have higher pain and disability levels and a lower quality of life. This seems in general agreement with anecdotal evidence.. So pain and sleep loss may contribute to one another. Experiencing chronic pain can lead to sleep deprivation, but sleep deprivation can also make pain symptoms worse. It becomes a chicken and egg situation where it may be difficult to determine which is causing which - most medical issues have a bi-directional component, simply put, both will influence the other to a degree. ...
Rapid eye movement sleep is maximal during early life, but its function in the developing brain is unknown. We investigated the role of rapid eye movement sleep in a canonical model of developmental plasticity in vivo (ocular dominance plasticity in the cat) induced by monocular deprivation. Preventing rapid eye movement sleep after monocular deprivation reduced ocular dominance plasticity and inhibited activation of a kinase critical for this plasticity (extracellular signal-regulated kinase). Chronic single-neuron recording in freely behaving cats further revealed that cortical activity during rapid eye movement sleep resembled activity present during monocular deprivation. This corresponded to times of maximal extracellular signal-regulated kinase activation. These findings indicate that rapid eye movement sleep promotes molecular and network adaptations that consolidate waking experience in the developing brain.. ...

BACKGROUND: Poor sleep quality (SQ) and daytime sleepiness (DS) are common in renal transplant (RTx) recipients; however, related data are rare. This study describes the prevalence and frequency of self-reported sleep disturbances in RTx recipients. METHODS: This cross-sectional study included 249 RTx recipients transplanted at three Swiss transplant centers. All had reported poor SQ and / or DS in a previous study. With the Survey of Sleep (SOS) self-report questionnaire, we screened for sleep and health habits, sleep history, main sleep problems and sleep-related disturbances. To determine a basis for preliminary sleep diagnoses according to the International Classification of Sleep Disorders (ICSD), 164 subjects were interviewed (48 in person, 116 via telephone and 85 refused). Descriptive statistics were used to analyze the data and to determine the frequencies and prevalences of specific sleep disorders. RESULTS: The sample had a mean age of 59.1 ± 11.6 years (60.2% male); mean time since ...
In the United States as many as forty million people suffer from chronic long term sleep disorders while as many as twenty million have occasional sleep disorders. Good health requires sleep, even though this phenomenon is not completely understood by scientists and medical professionals yet. Sleeps disorders have three major types and one of them is insomnia sleep disorder.. Insomnia is a very common sleep problem that is experienced by millions on occasion and it means a person is not able to fall asleep. A person with insomnia will have a disruption of normal daily life and they will often feel tired most of the time and end up worrying about their lack of sleep. Insomnia sleep disorder can be caused by a number of factors including excessive intake of caffeine or alcohol, emotional difficulties, stress and other underlying diseases. Lack of sleep isnt a disorder in itself, but it is an indication of inadequate sleep and can harm the immune system.. There are three categories of insomnia ...
Sleep research and sleep medicine have grown rapidly over the last thirty years, partly as a result of the discovery that REM (rapid eye movement) sleep coincided with dreaming and partly because of the discovery of sleep apnea (breathing stopping during sleep). Countries vary in how they deal with sleep disorders; in the U.S. sleep medicine is recognised as a field and it is looked after by the National Heart, Lung and Blood Institute; other medical specialities e.g. neurology, pulmonology, psychiatry, may be influential in other countries. The sleep disorders category is broadly divided into sub-categories that deal with the specific sleep disorders as well as the institutions that regulate, diagnose and treat these disorders. Sleep is affected by the brains biological clock and so is included in this category. Shift-work sleep disorder and jet-lag are well-known problems that reflect the activity of the biological clock. This category consists of some of the major omnibus sites (SleepNet,
Over 22 million Americans suffer from sleep apnea. The causes and intensity of symptoms of sleep apnea vary person to person, so its important to be aware of the treatment options available. Fortunately, Mercy Health has a new treatment for those who suffer from Obstructive Sleep Apnea called the Inspire Therapy.. Medical Director of Sleep Medicine Dr. Christopher Morgan stopped by to explain what sleep apnea is, what symptoms to look out for, and the technology behind new treatment options.. Obstructive sleep apnea is a potentially serious sleep disorder, causing breathing to repeatedly stop and start during sleep. Symptoms include excessive daytime sleepiness, snoring, stopping breathing during sleep, insomnia, excessive nighttime urination, awakening with a dry mouth or sore throat, morning headache, high blood pressure and nighttime sweating.. Patients should treat their sleep apnea so they dont experience daytime fatigue and sleepiness, which can increase the risk for car accidents and ...
Not getting enough sleep can make you sick, according to a new study.. Writing in the journal Sleep, researchers from the University of Washington say sleep deprivation depresses the bodys immune system.. To reach their conclusions, the researchers studied 11 pairs of identical twins with differing sleep patterns and found that the twin who slept less had a depressed immune system. Researchers noted that genetics account for 31 and 55 percent of sleep duration, with behavior and environment making up the rest.. What we show is that the immune system functions best when it gets enough sleep. Seven or more hours of sleep is recommended for optimal health, said lead author Dr. Nathaniel Watson, co-director of the UW Medicine Sleep Center at Harborview Medical Center.. Researchers said existing data on limited sleep deprivation in a lab setting can increase inflammatory markers and activate immune cells, but that less is known about long-term sleep deprivation in natural conditions.. This ...
Waking up at night and feeling like you were unable to breathe properly is the symptom of sleep apnea. A person having sleep apnea is hardly aware of his problem, even during awakening. A person may be having symptoms present for years. Symptoms may be chronic and loud snoring, choking during sleep, and long pauses in breathing. Less common symptoms of sleep apnea are: headaches in the morning, dry mouth, restless. Further sleep apnea is divided in to two types, obstructive and central sleep apnea: In obstructive sleep apnea airway of throat can obstruct breathing during sleep. Central sleep apnea is less common type of sleep apnea ...
The primary findings of this study are (1) athletes need 8.3 hours of sleep to feel rested, (2) athletes typically obtain 6.7 hours of sleep, (3) the most sleep is obtained by athletes who fall asleep between 22:00 and 22:30 hours (7.2 h) or wake up between 09:00 and 09:30 hours (7.6 h), (4) athletes involved in team sports (6.9 h) obtain more sleep than athletes involved in individual sports (6.4 h), and (5) female athletes have an earlier habitual sleep onset time than male athletes. Importantly, only 3% of athletes obtain enough sleep to satisfy their self-assessed sleep need, and 71% of athletes fall short by an hour or more. Insufficient or inadequate sleep, defined here as a failure to meet a required sleep need on a regular basis, could have important consequences for an elite athlete, particularly in terms of their ability to train effectively and/or compete optimally.. The average subjective sleep need reported by elite athletes in this sample was 8.3 hours. Similar values have been ...

The results of this study in 2,872 subjects demonstrate that periodic limb movements in sleep are common in elderly men. Overall, we found a strikingly high prevalence of PLMS when using a PLMI threshold of 5 (71%) or 15 (60%). When using a PLMA threshold of 5 (27%) or 15 (6%) as a disease-defining metric, PLMS was common but less prevalent. Importantly, both metrics were associated with poorer sleep outcomes after multivariate adjustment for various possible confounders. A higher PLMA was consistently associated with more frequent arousals, lower sleep efficiency, and a pattern of altered sleep stages suggesting lighter sleep (more stage 1 and 2 and less stage 3-4 and REM). Except for stage 1, REM and sleep efficiency, similar findings were consistently observed for PLMI. These results suggest that leg movements that do not cause arousals as well as those that do cause arousals are associated with perturbed sleep quality, although on average, these associations are modest in this sample with ...
Sleep loss is both common and critically relevant to our society and might lead to the abuse of psychostimulants such as amphetamines, cocaine and modafinil. Since psychoactive substance abuse often occurs within a scenario of sleep deficit, the purpose of this investigation was to compare the sleep patterns of rats challenged with cocaine (7 mg/kg, ip), methamphetamine (7 mg/kg, ip), or modafinil (100 mg/kg, ip) subsequent to paradoxical sleep deprivation (PSD) for 96 h. Our results show that, immediately after 96 h of PSD, rats (10 per group) that were injected with a psychostimulant presented lower percentages of paradoxical sleep compared to those injected with saline (P , 0.01). Regarding slow wave sleep (SWS), rats injected with psychostimulants after PSD presented a late rebound (on the second night subsequent to the injection) in the percentage of this phase of sleep when compared to PSD rats injected with saline (P , 0.05). In addition, the current study has produced evidence of the ...
Context:. There is growing recognition that a large number of individuals living in Western society are chronically sleep deprived. Sleep deprivation is associated with an increase in food consumption and appetite. However, the brain regions that are most susceptible to sleep deprivation-induced changes when processing food stimuli are unknown.. Objective:. Our objective was to examine brain activation after sleep and sleep deprivation in response to images of food.. Intervention:. Twelve normal-weight male subjects were examined on two sessions in a counterbalanced fashion: after one night of total sleep deprivation and one night of sleep. On the morning after either total sleep deprivation or sleep, neural activation was measured by functional magnetic resonance imaging in a block design alternating between high- and low-calorie food items. Hunger ratings and morning fasting plasma glucose concentrations were assessed before the scan, as were appetite ratings in response to food images after ...
14% and 21% decrease in their respective global PSQI scores. The proportion of Virta patients characterized as poor sleepers decreased by 12% and 29% in the type 2 diabetes and prediabetes groups, respectively. Patients who continued their usual care had no significant changes in self-reported sleep.. Sleep has a substantial impact on the overall health of people with type 2 diabetes, said Dr. Christa Van Dort, Assistant Professor of Anesthesia at Harvard Medical School, the studys senior author. With that in mind, it is promising that the Virta Treatment improved patients subjective sleep as indicated by significantly lower global PSQI scores in addition to improving their diabetes.. The Centers for Disease Control and Prevention has declared insufficient sleep a public health epidemic. T2D and obesity are frequently associated with poor sleep quality as well as obstructive sleep apnea (OSA), and improvement in sleep is associated with increased insulin sensitivity and glucose tolerance ...
Far too many Americans dont get enough sleep. When we feel pressed for time and have too much to do, we often sacrifice hours of sleep in order to cope. Maybe youre someone who actually boasts about how little sleep you need each night. But many of us dont understand just how vitally important that sleep is to our overall well-being. In fact, long-term sleep deprivation can be toxic to our health.. Without enough hours of sleep, we may wake up a little cranky and less focused than usual. But consistently getting insufficient sleep has larger, very real consequences to our physical health, too. Here are some of the harmful effects that sleep deprivation can have:. Lowered Immune Response. Studies report that people who arent getting enough sleep are at an increased chance of getting sick after being exposed to a virus. A persistent lack of sleep reduces the production of cytokines which are a type of protein that targets infection and inflammation.. Increased Risk of Type 2 Diabetes. Skimping ...
BACKGROUND AND AIMS: Orexins/hypocretins are orexigenic peptides implicated in the regulation of feeding behavior and the sleep/wake cycle. Little is known about the functioning of these peptides in anorexia nervosa (AN). The aims of the current study were to evaluate the extent to which orexin-A might be linked to sleep and treatment outcome in AN.METHOD: Fasting plasma orexin-A concentrations were measured in 48 females with AN at the start of a day hospital treatment and in 98 normal-eater/healthy-weight controls. The Pittsburgh Sleep Quality Index was administered at the beginning of the treatment as a measure of sleep quality. Other psychopathological variables were evaluated with the Symptom Checklist-Revised (SCL90R) and the Eating Disorder Inventory-2 (EDI). Patients were assessed at the start and end of treatment by means of commonly used diagnostic criteria and clinical questionnaires.RESULTS: The AN patients presented more sleep disturbances and poorer overall sleep quality than did ...
Sleep apnea is a severe disorder that happens when your breathing is interfered with during sleep. If it goes untreated, you may stop breathing several times as you sleep. Unfortunately, this means that your brain, as well as other body parts, may not get adequate oxygen supply. In this article, we will look at everything you need to know about sleep apnea and what to do to ease the problem.. What is sleep, apnea?. It is a common, yet severe sleep disorder that makes breathing shallow, or stop entirely during sleep. Sometimes, the breathing pause may take about 10 seconds or more and may happen about 30 or more times in one hour. The involuntary pause can arise due to an obstructed airway (obstructive sleep apnea - OSA) or a signaling issue in the brain (central sleep apnea - CSA). The person involuntarily stops breathing continuously throughout sleep. Once the breathing signal is received, or the airway opens, the person may take a deep breath, snort or fully awaken with a choking, smothering, ...
This occurs occasionally in around 50% of normal subjects and frequently in around 6%, usually in adolescents and the elderly, especially with REM sleep rebound following sleep deprivation and jet lag following east-west travel which induces sleep-onset REM sleep. There is also a familial tendency to sleep paralysis.. Table 6.9 Differential diagnosis of cataplexy.. Sleep attack. Epilepsy, especially gelastic and atonic. Vertebro-basilar insufficiency. Cardiac dysrhythmias. Drop attacks. Myasthenia gravis. Periodic paralysis. Faints. Gelastic syncope Hysteria. Table 6.10 Differential diagnosis of vivid dreams in narcolepsy.. Sleep paralysis should be distinguished from the generalized fatigue on waking which is common in the chronic fatigue syndrome and depression and is due to a lack of motivation rather than true paralysis. This lasts longer than sleep paralysis and small movements, for instance of the fingers, are possible. Sleep paralysis may also be confused with atonic seizures, transient ...
Atrial fibrillation can be caused by sleep apnea therefore 100% of patients with SAtrial Fibrillation should be evaluated for sleep apnea. Patients with Atrial Fibrillation should be tested even if they have none of the commonly seen symptoms of apnea such as snoring, excessive tirednedd, weight gain or hypertension. Many patients have sleep apnea but do not fit picture often associated with apnea. Unfortunately while the percentage of patients with sleep apnea in cardiology offices may be as high as 70% it is estimated only 10-20% are ever diagnosed. I have recently created a new company Sleep Well Illinois to set up UNIVERSAL SLEEP APNEA SCREENING IN CARDIOLOGY PRACTICES AND INTERNAL MEDICINE OFFICES. https://www.sleepandhealth.com/node/653.

To examine the effectiveness and safety of yoga of women with sleep problems by performing a systematic review and meta-analysis. Medline/PubMed, ClinicalKey, ScienceDirect, Embase, PsycINFO, and the Cochrane Library were searched throughout the month of June, 2019. Randomized controlled trials comparing yoga groups with control groups in women with sleep problems were included. Two reviewers independently evaluated risk of bias by using the risk of bias tool suggested by the Cochrane Collaboration for programming and conducting systematic reviews and meta-analyses. The main outcome measure was sleep quality or the severity of insomnia, which was measured using subjective instruments, such as the Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), or objective instruments such as polysomnography, actigraphy, and safety of the intervention. For each outcome, a standardized mean difference (SMD) and confidence intervals (CIs) of 95% were determined. Nineteen studies in this systematic
BACKGROUND & AIMS: Sleep disturbance is associated with the development of obesity, diabetes and hepatic steatosis in murine models. Hepatic triglyceride accumulation oscillates in a circadian rhythm regulated by clock genes, light-dark cycle and feeding time in mice. The role of the sleep-wake cycle in the pathogenesis of human non-alcoholic fatty liver disease (NAFLD) is indeterminate. We sought to detail sleep characteristics, daytime sleepiness and meal times in relation to disease severity in patients with NAFLD. METHODS: Basic Sleep duration and latency, daytime sleepiness (Epworth sleepiness scale), Pittsburgh sleep quality index, positive and negative affect scale, Munich Chronotype Questionnaire and an eating habit questionnaire were assessed in 46 patients with biopsy-proven NAFLD and 22 healthy controls, and correlated with biochemical and histological parameters. RESULTS: In NAFLD compared to healthy controls, time to fall asleep was vastly prolonged (26.9 vs. 9.8 min., p = ...
During sleep, your body alternates between REM (rapid eye movement) and NREM (non-rapid eye movement) sleep. One cycle of REM and NREM sleep lasts about 90 minutes. NREM sleep occurs first and takes up to 75% of your overall sleep time. During NREM sleep, your body relaxes and restores itself. At the end of NREM, your sleep shifts to REM. Your eyes move quickly and dreams occur, but the rest of your body remains very relaxed. Your muscles are turned off during REM sleep. If you become aware before the REM cycle has finished, you may notice that you cannot move or speak ...
Sleep apnea is a common disorder in which breathing stops during sleep for 10 seconds or more, sometimes more than 300 times a night. The hallmark of the disorder is excessive daytime sleepiness and compromised quality of life, including significant social and emotional problems. There are two main types of sleep apnea. Obstructive sleep apnea may represent cessation of breathing due to mechanical blockage of the airway; central sleep apnea appears to be related to a malfunction of the brains normal signal to breathe. Symptoms of sleep apnea may include restless sleep, loud, heavy snoring (often interrupted by silence and then gasps), falling asleep while driving and/or during the day (at work, watching TV, etc.), morning headaches, loss of energy, trouble concentrating, irritability, forgetfulness, mood or behavior changes, anxiety or depression, obesity, and decreased interest in sex. Not all people with sleep apnea experience all of these symptoms and not everyone who has these symptoms ...
Snoring and Sleep Apnea are very often linked. Sleep Apnea Syndromes by nature affect how one breathes in sleep. Because of this, many peoples bed partners will have witnessed different breathing patterns that will result in further evaluation for sleep apnea conditions. Snoring is the most common respiratory disturbance in sleep. It results from a partial airway obstruction that serves as a whistle causing the snoring noises. Snoring however does not confirm Obstructive Sleep Apnea syndrome, however, as snoring can exist without any sleep disruption, apneas, or hypopneas. The important point is that if a partial obstruction exists and is causing snoring, then the same obstruction may be causing a sleep apnea condition.. Other breathing patterns that are described during sleep include actual periods where the individual is noted to pause in breathing. Also, gasping for air after a pause is common, and can be frightening for the observer. Noises can range from a soft snore to a coarse loud ...
Background: Short sleep duration has been linked to impaired glucose metabolism in many experimental studies. Moreover, studies have reported indications of an increased metabolic stress following sleep restriction. Objective: We aimed to investigate the effects of partial sleep deprivation on markers of glucose metabolism. Additionally, we aimed to investigate if short sleep duration induces a state of endocrine stress. Design: A randomized crossover design, with 2 experimental conditions: 3 consecutive nights of short sleep (SS, 4 h/night) and long sleep (LS, 9 h/night) duration. Subjects and Measurements: In 21 healthy, normal-weight male adolescents (mean +/- SD age: 16.8 +/- 1.3 y) we measured pre- and post-prandial glucose, insulin, C-peptide, and glucagon concentrations. Furthermore, we measured fasting cortisol, 24-h catecholamines, and sympathovagal balance. Results: Fasting insulin was 59% higher (P = 0.001) in the SS than the LS condition as was both fasting (24%, P , 0.001) and ...
Objectives - A retrospective study has been done at the Bethesda Childrens Hospital Epilepsy Center with those patients whose EEG records fulfilled in one or more records the criteria of electrical status epilepticus in slow wave sleep (ESES) pattern, occupying at least 75% of NREM sleep with bilateral discharges, and had detailed disease history and long term follow-up data, between 2000 and 2012. Patients and methods - Thirty-three patients (mean 11.1±4.2 years of age) were studied by 171 sleep EEG records. Sleep was recorded after sleep deprivation or during spontaneous sleep at least for one hour length of NREM. From the 492 EEGs, 171 sleep records were performed (average five/patient). Average follow-up time was 7.5 years. Eighty-two ESES records have been analyzed in 15 non-lesional and 18 lesional (11 with dysgenetic and seven with perinatal - asphyxic or vascular origin) patients. Variability of seizure types, seizure frequency and frequency of status epilepticus was higher in the lesional
Abnormal sleep may associate with cognitive decline in Parkinsons disease (PD). Furthermore, sleep dysfunction may associate with worse motor outcome. We hypothesised that PD patients with poor quality sleep would have greater progression in gait dysfunction, due to structural and functional overlap in networks subserving sleep and gait regulation. 12 PD patients and 12 age-matched controls completed longitudinal follow-up over 36 months. Poor sleep efficiency and greater sleep fragmentation correlated significantly with progression of step-width variability, a gait characteristic mediated by postural control, providing evidence that poor sleep in PD is associated with a more rapid deterioration in gait.. ...
Occasionally its possible to have sleep apnea prior to being conscious of it. Sleep apnea is significantly more serious than many realize. Severe sleep apnea can triple your odds of stroke.. Sleep Apnea is extremely common among American adults. It is a major sleep disorder wherein a person abruptly wakes up in the middle of sleep because of blockage in the airway. While its not normally thought of as a serious disease it can have a very negative impact on your life and,if left untreated,could lead to death. If youre aware that you have got sleep apnea,or even suspect that,then speak to your physician about assembling a sleep study so you can get fitted for a CPAP. Therefore,in case you have severe sleep apnea and other therapies have not helped,you want to be certain to speak with your healthcare provider about operation as a possible choice.. } Staying at a wholesome weight is 1 approach to reduce apnea. Sleeping apnea is just among the most frequently encountered problems prevailing around ...
Purpose: To investigate the effects of combined sleep hygiene recommendations and mindfulness on actigraphy-based sleep parameters, perceptual well-being, anxiety, and match outcomes during high-performance junior tennis tournaments. Methods: In a randomized crossover design, 17 high-performance junior tennis players completed the baseline, control, and intervention (INT) conditions across 3 separate weeks. The baseline consisted of unassisted, habitual sleep during a regular training week, and the control was unassisted sleep during a tournament week. The players attended a sleep education workshop and completed a nightly sleep hygiene protocol during a tournament week for the INT. Analysis was performed on the weekly means and on the night prior to the first match of the tournament (T-1). Results: Significant differences were observed for increased time in bed, total sleep time, and an earlier bedtime (P , .05) across the INT week. These parameters also significantly improved on T-1 of the ...
Sleep disorders are a risk factor for developing a variety of mental disorders, have a negative impact on their remission rates and increase the risk of relapse. Early identification and treatment of sleep disorders is therefore of paramount importance. Unfortunately, in mental health care sleep disorders are often poorly recognized and specific treatment frequently occurs late or not at all. This protocol-paper presents a randomized controlled trial investigating the clinical relevance of early detection and treatment of sleep disorders in mental health care. The two aims of this project are 1) to determine the prevalence of sleep disorders in different mental disorders, and 2) to investigate the contribution of early identification and adequate treatment of sleep disorders in individuals with mental disorders to their sleep, mental disorder symptoms, general functioning, and quality of life. Patients newly referred to a Dutch mental health institute for psychiatric treatment will be screened for sleep
Evidence-based assessment of the psychometric properties of available paediatric sleep instruments is needed (Lewandowski et al., 2011; Spruyt and Gozal, 2011). The current study examined the factor structure, internal consistency reliability and concurrent validity of the ASHS using a community-based urban sample of 16-19-year-old adolescents. The empirical factor structure of the revised 24-item scale (ASHSr) is largely consistent with the theoretically based structure proposed initially (LeBourgeois et al., 2005), with the exceptions that the cognitive and emotional domains were combined into one factor and a new behavioural arousal construct was identified. Internal consistency reliability of the ASHSr as well as concurrent validity with objective measures of sleep and convergent validity with behavioural outcomes indicate that the ASHSr has satisfactory psychometric properties for a research instrument to assess adolescent sleep hygiene.. Sleep hygiene was correlated modestly with objective ...
The power of music to aid sleep is evidenced in the existence of music for sleep CDs and radio stations. Despite their popularity, there is little evidence-based research on how sleep quantity or quality is impacted by music.. In particular, no study to date has combined music with sleep measures for long enough to be effective and most studies take place in hospitals not in peoples own beds.. Our research will redress this situation by first, carrying out a large-scale Internet survey on music and sleep, to determine how people are currently using music when they encounter sleep difficulties in their day-to-day life. Using the results of this survey we will then carry out an informed, long-term music for sleep intervention study in peoples own homes using new sleep monitoring technologies.. Our research team combines different expertise to explore new pathways to impact for music and sleep research. We also aim to train postgraduate students in the UK in the use of sleep technologies and ...
A hypnogram is a form of polysomnography; it is a graph that represents the stages of sleep as a function of time. It was developed as an easy way to present the recordings of the brain wave activity from an electroencephalogram (EEG) during a period of sleep. It allows the different stages of sleep: rapid eye movement sleep (REM) and non-rapid eye movement sleep (NREM) to be identified during the sleep cycle. NREM sleep can be further classified into NREM stage 1, 2 and 3. The previously considered 4th stage of NREM sleep has been included within stage 3; this stage is also called slow wave sleep (SWS) and is the deepest stage of sleep. Each of the three NREM stages as well as the period of REM sleep and the awake state can be determined and displayed on a hypnogram. Hypnograms are usually obtained by visually scoring the recordings from electroencephalogram (EEGs), electrooculography (EOGs) and electromyography (EMGs). The output from these three sources is recorded simultaneously on a graph ...

your life.. So what is the difference between snoring and and Apnea? Sleep Apnea is a breathing obstruction which would require the individual to wake up in order to breathe again. Snoring is just simply a loud noise a person makes while sleeping. If you experience sleep apnea, you would usually wake up at nights to regain breathing but have no recollection about them the next morning.. Common signs of this disease are disrupted breathing, gagging and gasping during sleep and frequent episodes of waking during the night. Usually a diagnosis is made after the bed partner provides the information to the doctor about the sleeping disorder so that the doctor can make a diagnosis on the individual.. During diagnosis, a doctor will perform an exam of your mouth and most likely recommend a sleep study at a clinic to do some monitoring.. The 3 types of sleep apnea that exist are: Obstructive Sleep Apnea, Central Sleep Apnea and Mixed Sleep Apnea.. Causes of this disorder are obstructed airways, chronic ...
|jats:title|Abstract|/jats:title||jats:p|Serotonergic psychedelic drugs, such as psilocin (4-hydroxy-N,N-dimethyltryptamine), profoundly alter the quality of consciousness through mechanisms which are incompletely understood. Growing evidence suggests that a single psychedelic experience can positively impact long-term psychological well-being, with relevance for the treatment of psychiatric disorders, including depression. A prominent factor associated with psychiatric disorders is disturbed sleep, and the sleep-wake cycle is implicated in the regulation of neuronal firing and activity homeostasis. It remains unknown to what extent psychedelic agents directly affect sleep, in terms of both acute arousal and homeostatic sleep regulation. Here, chronic |jats:italic|in vivo|/jats:italic| electrophysiological recordings were obtained in mice to track sleep-wake architecture and cortical activity after psilocin injection. Administration of psilocin led to delayed REM sleep onset and reduced NREM sleep
