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 ...
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 ...

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 ...

Objective: To evaluate the association of SDB during REM sleep with daytime sleepiness, health-related QOL, and difficulty maintaining sleep, in comparison to their association with SDB during non-REM sleep in a community-based cohort. Methods: Cross-sectional analysis of 5,649 Sleep Heart Health Study participants (mean age 62.5 [SD = 10.9], 52.6% women, 22.6% ethnic minorities). SDB during REM and non-REM sleep was quantified using polysomnographically derived apnea-hypopnea index in REM (AHIREM) and non-REM (AHINREM) sleep. Sleepiness, ...
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

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 ...
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 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 ...
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). Improving sleep quality may be helped by better sleep habits or being diagnosed and treated for any sleep disorder you may have.. ...
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 ...
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 ...

Background: Sleep disturbance has been described as a hallmark symptom of posttraumatic stress disorder (PTSD). Although there are robust findings of self-reported sleep disturbance in PTSD, evidence of sleep disturbance measured using actigraphy is less certain.. Objective: To conduct a systematic review and meta-analysis to determine whether there are any significant differences between individuals with and without PTSD in actigraph-derived sleep measures.. Method: Case-control studies comparing participants with current PTSD to those without PTSD were eligible for inclusion. Sleep parameters of interest were: (1) total sleep time; (2) sleep onset latency; (3) wake after sleep onset (WASO); and (4) sleep efficiency. Data were meta-analysed as standardised mean differences (SMDs) and potential sources of ...
Pregnant women in Ghana who slept on their back (supine sleep) were at an increased risk of stillbirth compared to women who did not sleep on their back, according to new research led by a University of Michigan researcher.. "Association of maternal sleep practices with pre-eclampsia, low birth weight, and stillbirth among Ghanaian women" is published in the International Journal of Gynecology and Obstetrics.. Read Abstract.. In the study, researchers found that supine sleep increased the risk of low birth weight by a factor of 5 and that it was the low birth weight that explained the high risk for stillbirth in these women.. The studys senior author, Louise OBrien, Ph.D., M.S., associate professor in U-Ms Sleep Disorders Center, says that although this study was conducted in a maternity hospital in Ghana - a country that has high perinatal mortality - a recent case-control study from New Zealand also found a link between maternal supine sleep and stillbirth.. Stillbirth is a traumatic event ...
For a good nights sleep try these healthy sleep habits, by optimizing your sleep sanctuary. To improve your sleep, you may need to modify some of your lifestyle choices, including diet and exercise. When your circadian rhythms are disrupted your body produces less melatonin (a hormone and an anti-oxidant) and has less ability to fight disease, since melatonin helps suppress free radicals.. Impaired sleep an also increase stress-related disorder, including: Heart Disease, Stomach Ulcers, Constipation, Mood Disorders. One study has even shown that people with chronic insomnia have a three times greater risk of dying from any cause. Lost sleep is lost forever, and persistent lack of sleep has a cumulative effect when it comes to disrupting your health. Whether you have trouble falling asleep, waking up too often, or feeling inadequately rested when you wake up in the morning-or maybe you simply want to improve the quality of your sleep-Try these healthy sleep habits:. 1.

Background: The purpose was to examine the effect of the antidepressant drug venlafaxine on sleep architecture and periodic leg movements of sleep (PLMS) in normal volunteers.. Method: Eight normal volunteers were studied under laboratory sleep conditions as follows: 1 acclimatization night, 1 baseline night, and 4 consecutive nights of venlafaxine p.o. administration (75 mg during the first 2 nights and 150 mg the last 2 nights). Results: Venlafaxine increased both wake time and sleep stage I. Sleep stages II and III were reduced. REM sleep time was reduced after the first venlafaxine dose, and, by the fourth night, REM sleep was completely suppressed in all volunteers. Six of the eight volunteers showed PLMS at a frequency above 25 per hour. Conclusion: Venlafaxine produces several sleep disturbances, which include abnormal leg movements. ...
Sleep and pain have a difficult, multidimensional relationship. Pain disturbs sleep.1-4 Disturbed sleep aggravates pain.5-8 Treatment of sleep disorders can reduce pain.9 Relieving pain can improve sleep although, as shown by Correa and colleagues10 in this issue of Anesthesia & Analgesia, where opioids are involved this is not uniformly the case.. Sleep is a vulnerable state for breathing. Ventilatory drive is reduced because of loss of the stimulatory effects of wakefulness, accompanied by reduction in hypercapnic and hypoxic responsiveness. Sleep depresses muscle activation, reflex gain, and arousal responses. These changes are more prominent in rapid eye movement than non-rapid eye movement sleep. Upper airway obstruction and/or hypoventilation occur in predisposed subjects.11 This makes sleep of enormous relevance to anesthesiologists, as these state-related physiological changes are also present during anesthesia. Knowledge of breathing behavior during sleep is helpful in predicting likely ...
Chronic snoring is a strong indicator of sleep apnea and should be evaluated by a health professional. Since people with sleep apnea tend to be sleep deprived, they may suffer from sleeplessness and a wide range of other symptoms such as difficulty concentrating, depression, irritability, sexual dysfunction, learning and memory difficulties, and falling asleep while at work, on the phone, or driving. Left untreated, symptoms of sleep apnea can include disturbed sleep, excessive sleepiness during the day, high blood pressure, heart attack, congestive heart failure, cardiac arrhythmia, stroke or depression.. ​One of the most common methods used to diagnose sleep apnea is a sleep study, which may require an overnight stay at a sleep center. The sleep study monitors a variety of functions during sleep including sleep state, eye movement, muscle activity, heart rate, respiratory effort, airflow, and blood oxygen levels. ...
A recent study reported in the journal Brain, showed that Parkinsons patients improved their working memory if they had a good night sleep. Working memory is what is required to organize, plan, solve problems and function in daily living. This is a significant issue for patients with Parkinsons disease.. The study looked at 54 patients with Parkinsons disease to see the affects of sleep on their working memory. What they found was that if a patient had sleep apnea and interfered with their slow wave sleep (the deepest level of sleep), they had significantly more difficulty with their working memory. However, as they improved their slow wave sleep duration by treating their apnea, their memory improved.. This is similar with other studies showing that the slow wave sleep is needed to allow the brain to reorganize and make new connections. So, if sleep disorders are addressed in Parkinsons patients, then there is a good chance that their working memory will improve.. This is exciting news for ...
Insufficient sleep - due to inadequate or mistimed sleep - contributes to the risk for several of todays public health epidemics, including cardiovascular disease, diabetes and obesity. Getting at least seven hours of nightly sleep is a key to overall health, which translates to less sick time away from work," said American Academy of Sleep Medicine President Dr. Timothy Morgenthaler, a national spokesperson for the Healthy Sleep Project. The "Sleep Well, Be Well" campaign was launched earlier this year to increase awareness of the importance of sleep as one of the three pillars of a healthy lifestyle.. The study involved a nationally representative survey of 3,760 men and women in Finland who had been working at any time in the prior year. Participants were 30-64 years old at baseline. Sleep characteristics were determined by questionnaire, and health measures were derived from physical examination conducted by field physicians. Data for work absences due to sickness were gathered from the ...
Sleep is a state of relative unconsciousness and stillness of the voluntary muscles (muscles that are controlled at will). The stages of sleep range from light to deep and each one has specific characteristics that can be measured. A sleep study consists of a number of medical tests performed at the same time during sleep. The tests measure specific sleep characteristics and help to diagnose sleep disorders. A sleep study may also be referred to as a polysomnogram.. The term "polysomnogram" indicates that there are multiple tests in a sleep study. Breaking the word into parts, "poly" means many, while "somno" means sleep and "gram" means recording - many sleep recordings. The basic recordings may include:. ...
The evolution of different types of sleep patterns is influenced by a number of selective pressures, including body size, relative metabolic rate, predation, type and location of food sources, and immune function.[29][30][31][32] Sleep (especially deep SWS and REM) is tricky behavior because it steeply increases predation risk. This means that, for sleep to have evolved, the functions of sleep should have provided a substantial advantage over the risk it entails. In fact, studying sleep in different organisms shows how they have balanced this risk by evolving partial sleep mechanisms or by having protective habitats. Thus, studying the evolution of sleep might give a clue not only to the developmental aspects and mechanisms, but also to an adaptive justification for sleep. One challenge studying sleep evolution is that adequate sleep information is known only for two phyla of animals- chordata and arthropoda.[7] With the available data, comparative studies have been used to determine how sleep ...

A common misperception maintains that, as people age, they need less sleep. The truth is that sleep needs dont diminish, but sleep difficulties do. Some of this pattern - called sleep architecture - may indeed spring from aging but often its associated with the medicines that are increasingly taken for the various physical and psychological difficulties associated with aging.. Older adults often experience poor sleep latency (the time it takes to fall asleep), as well as frequent waking-during-sleep experiences and early risings. The amount of deep sleep can also diminish, making the overall quality of sleep inferior. Some attribute this change in older adults circadian rhythms to changes in light - perhaps too much, perhaps too little.. Older adults are also more subject to advanced sleep phase disorder, which means that they tend to fall asleep earlier and wake up earlier. Insomnia is also more commonly reported by older Americans, by some 44 percent of that population.. Why older adults ...
The Sleep Apnea & Heart Failure Connection. If you are waking up often during the night or annoying your loved ones with epic snoring, you could be suffering from a condition called sleep apnea. It is a relatively common sleep disorder, but its implications can be a lot more serious than poor sleep quality.. Sleep apnea can lead to a range of cardiovascular diseases, including high blood pressure, stroke, arrhythmia and congestive heart failure. Untreated sleep apnea may significantly increase your risk of dying from heart disease. Studies suggest that anywhere from 40% to 70% of patients with heart failure show evidence of sleep apnea, making it one of the most common comorbidities in people with heart failure.. Sleep apnea is a disorder that causes a person to periodically stop breathing while asleep. These pauses in breathing can occur up to hundreds of times during the night, often waking the sleeper as they gasp for air. The most common form of sleep apnea is obstructive sleep apnea (OSA). ...
Respiratory volumes and timing have been measured in 19 healthy adults during wakefulness and sleep. Minute ventilation was significantly less (p less than 0.05) in all stages of sleep than when the subject was awake (7.66 +/- 0.34(SEM) 1/min), the level in rapid-eye-movement (REM) sleep (6.46 +/- 0.29 1/min) being significantly lower than in non-REM sleep (7.18 +/- 0.39 1/min). The breathing pattern during all stages of sleep was significantly more rapid and shallow than during wakefulness, tidal volume in REM sleep being reduced to 73% of the level during wakefulness. Mean inspiratory flow rate (VT/Ti), an index of inspiratory drive, was significantly lower in REM sleep than during wakefulness or non-REM sleep. Thus ventilation falls during sleep, the greatest reduction occurring during REM sleep, when there is a parallel reduction in inspiratory drive. Similar changes in ventilation may contribute to the REM-associated hypoxaemia observed in normal subjects and in patients with chronic ...

In a single-blind study six male patients (mean age 39.5 years) with moderate insomnia were treated with placebo for three nights, 100 mg indole-3-pyruvic acid (IPA) for three nights, 200 mg IPA for three nights, 100 mg IPA for two nights and placebo for two nights. Polygraphic recordings were made and total sleep time, sleep efficiency, sleep latency, slow wave sleep latency, rapid eye movement (REM) sleep latency, number of arousals (greater than 1 min), percentage and duration of wakefulness after sleep onset, percentage and duration of wakefulness after sleep onset, percentage and duration of sleep stages 1, 2, 3, 4 and REM were recorded. At the end of 13 days, total sleep time, duration of stage 2 sleep and total non-REM were significantly increased when compared with baseline. Total sleep time and duration of stage 2 and total non-REM sleep on completion were significantly decreased when compared with after 200 mg IPA (night 9). Results suggest an action of IPA on human sleep similar to that of
