Heat-related mortalities will witness a two-fold increase in urban areas of India by 2080, a study done by the Indian Institute of Management-Ahmedabad (IIM-A) predicts.. The IIM study titled as Predicted increase in heat- related mortality under climate change in urban India also asked the Indian policy-makers to plan and respond to the challenge of climate change in the country, which recorded more than 2000 deaths in summer this year.. Urban areas in India are projected to witness two-fold or more increase in heat-related mortality under the projected future climate, the study conducted by IIM-A researcher Amit Garg, Vimal Mishra of Indian Institute of Gandhinagar and a member of Delhi-based NGO Council for Energy, Environment and Water, Hem Dholakia said.. The study, which is based on data collected from 52 Urban centres, said the mortality is projected to increase 71 to 140 per cent in the late 21st century.. We find that increase in heat-related mortality will overshadow decline in ...

OSHA does not have a specific standard that covers working in hot environments. Nonetheless, under the OSH Act, employers have a duty to protect workers from recognized serious hazards in the workplace, including heat-related hazards. This guide helps employers and worksite supervisors prepare and implement hot weather plans. It explains how to use the heat index to determine when extra precautions are needed at a worksite to protect workers from environmental contributions to heat-related illness. Workers performing strenuous activity, workers using heavy or non-breathable protective clothing, and workers who are new to an outdoor job need additional precautions beyond those warranted by heat index alone.. Workers new to outdoor jobs are generally most at risk for heat-related illnesses. For example, Cal/OSHA investigated 25 incidents of heat-related illness in 2005. In almost half of the cases, the worker involved was on their first day of work and in 80% of the cases the worker involved had ...

OPS 13: Heat, cold and mortality, Room 117, Floor 1, August 26, 2019, 1:30 PM - 3:00 PM. Background & Aim: While it is widely accepted that climate change will increase heat-related deaths in the future, limited quantitative evidence exists on current and past impacts already attributable to climate change. This large global study aims at estimating the proportion of excess heat-related mortality attributed to global warming experienced in recent decades across various regions of the world, by comparing impact estimates derived under actual trends and pre-industrial projection scenarios.. Methods: We studied 601 locations across 30 countries included in MCC database for which observed daily temperature-mortality data was available for at least 2 years between 1995 and 2005. Location-specific summer-only temperature-mortality associations were estimated through two-stage time-series analyses with quasi-Poisson regression with distributed lag non-linear models and multivariate meta-regression. ...

The majority of recent heat-related deaths investigated by federal authorities involved workers whod been on the job for three days or less.

Our systematic review suggests that pregnant women can participate in up to 35 min of very high-intensity aerobic exercise (~90% HRmax) at air temperatures of up to 25°C and 45% RH without attaining or exceeding a core temperature of 39.0°C; the hypothesised teratogenic threshold during pregnancy.10-12 Similarly, no study has ever reported the core temperature of a pregnant woman to exceed 38.0°C, 1.0°C lower than the critical maternal core temperature, when exercising in a warm bath (30°C37 38) or during resting exposure to a hot and dry sauna (70°C; 15% RH34) or immersion in a 40°C water bath41 for up to 20 min. Change in core temperature during exercise/heat exposure appears to decline with progressive pregnancy (figure 3).. While the downstream benefits to the children of pregnant women who engage in regular physical activity prior to and throughout pregnancy have been well documented,18-20 exercise inevitably results in the production of heat, which must be liberated to the ...

The Health Hazard Evaluation Program received a request from the safety manager at a national park in California. The safety manager asked NIOSH to evaluate park employees working in extreme heat, review the parks current and proposed heat stress management policies, and recommend ways to prevent heat-related illnesses. The park covers 3.4 million acres with elevations ranging from 282 feet below

Arterial compliance, the inverse of arterial stiffness, is a prognostic indicator of arterial health. Central and peripheral arterial compliance decrease with acute cold stress and may increase postexercise when exercise-induced elevations in core temperature are likely still to be present.

TY - JOUR. T1 - Effect of heat stress on production parameters and immune responses of commercial laying hens. AU - Mashaly, M. M.. AU - Hendricks, G. L.. AU - Kalama, M. A.. AU - Gehad, A. E.. AU - Abbas, A. O.. AU - Patterson, Paul H.. PY - 2004/1/1. Y1 - 2004/1/1. N2 - The present study was conducted to determine the adverse effects of high temperature and humidity not only on live performance and egg quality but also on immune function in commercial laying hens. One hundred eighty 31-wk-old laying hens at peak production were used in this study. Hens were housed in cages (15 cages of 4 birds/cage) in each of 3 environmental chambers and received 1 of 3 treatments. The 3 treatments were control (average temperature and relative humidity), cyclic (daily cyclic temperature and humidity), and heat stress (constant heat and humidity) for 5 wk. Different production and immune parameters were measured. Body weight and feed consumption were significantly reduced in hens in the heat stress group. Egg ...

Living organisms can survive only within a certain temperature range. When the ambient temperature is excessive, humans and many animals cool themselves below ambient by evaporative cooling (sweat in humans and horses, saliva and water in dogs and other mammals); this helps to prevent potentially fatal hyperthermia due to heat stress. The effectiveness of evaporative cooling depends upon humidity; wet-bulb temperature, or more complex calculated quantities such as Wet Bulb Globe Temperature (WBGT) which also takes account of solar radiation, give a useful indication of the degree of heat stress, and are used by several agencies as the basis for heat stress prevention guidelines. A sustained wet-bulb temperature exceeding 35 °C (95 °F) is likely to be fatal even to fit and healthy people, unclothed in the shade next to a fan; at this temperature our bodies switch from shedding heat to the environment, to gaining heat from it.[8] Thus 35 °C (95 °F) is the threshold beyond which the body is no ...

When temperatures begin to rise, concerns of an athlete succumbing to heat illness begin to rise as well. If an individual is active in the heat for too long, there are usually negative consequences, such as fainting (syncope), dizziness, nausea, excessive sweating, elevated core temperature and, if not monitored, death. To help prevent these consequences, here are simple yet crucial guidelines for nutrition, hydration and acclimatization to combat heat illness. There are five types of heat illnesses that coaches, parents and athletes should be on the lookout for.

The potential influence of aerobic fitness on RPE estimations during extended exercise bouts is not well understood. The current study compared RPE-Overall, RPE-Legs and RPE-Chest between fit (n=7) and unfit (n=6) males. Subjects completed a graded cycling test and then, in a counterbalanced order, on two separate days cycled for 60min (intensity~90% of the Onset of Blood Lactate Accumulation (OBLA) - determined via gas exchange indices) at 30 }1 degrees Wet Bulb Globe Temperature (WBGT) and 18 }1 degrees WBGT. Heart rate (HR), rectal temperature (Tree) and overall and differentiated RPE estimations were collected every 5 minutes. Repeated measures analyses of variance showed no significant differences (p|0.05) between groups for RPE-O, RPE-L, RPE-C. There were no significant differences between groups across time for HR or Tree. Similarly, there was no significance between - group differences for core temperature increase (Tree at 60min - Tree at 0 min) or absolute HR drift (HR at 60min- HR at 5min)

This project was conducted as part of a wider evaluation of compliance with JSP 539 in the hot CTE. This reported a mature and well developed approach to reducing extrinsic risk factors, but also identified a critical shortfall in the time allowed for heat acclimatisation. Seven days is specified in JSP 539,8 yet periods of shorter length were reported by 83.2% of respondents, of whom more than half reported no recognisable acclimatisation programme. Other investigations confirmed that inadequate time had been allocated for troops to acclimatise, with requirements for handover/takeover of equipment and other logistic constraints cited as contributory factors. In unacclimatised personnel undertaking strenuous physical activity, heat illness peaks during the first few days in a hot environment.19 Taking heat illness casualties early in the course of an exercise will maximally impact upon BG training objectives, due to the medical imperative to remove them from the hot CTE.. In mitigation of these ...

What is the central question of this study? Although heat stress is known to increase cardiovascular strain, no study, to date, had explored the potential impact of exercise-induced heat stress on vascular function. What is the main finding and its importance? We found that acute exercise tended to reduce flow-mediated dilatation (FMD), owing in part to reduced reactive hyperaemia/shear stimulus; thus, when FMD is normalized to shear no postexercise deficit exists. Exercise-induced heat stress increased reactive hyperaemia, shear rate, coupled with a sustained FMD postexercise, suggests that exercise-induced heat stress increases the amount of shear stimulus to elicit a similar response, indicating reduced vascular responsiveness, or reserve, which might increase cardiovascular susceptibility.

Changes in cutaneous circulation in response to local and whole body heat stresses have been reported to occur due to a combination of local and neurally mediated vasodilation of the cutaneous vascular system. These mechanisms are predominantly mediated by temperature changes and result in shunting of blood from the core to the periphery at upwards of 7-8L/min in cases of where profound heat stresses are applied.

June is a great time for outdoor fun and activities. But when the weather turns hot and humid, it is important to take precautions against heat-related illness.

IN the world of occupational heat stress, including professional sports such as American football, employers and employees must find some accommodation between reasonable productivity and reasonable heat stress illness prevention.

Results of the present study confirmed the association between climatic conditions and chemical characteristics of milk (Bouraoui et al., 2002; Prasad et al., 2012; Bertocchi et al., 2014).. Change of milk fat, protein and lactose percentages during hot weather could be attributed to the reduction of dry matter intake, and consequently energy intake, which in turn can be responsible in the reduction of milk synthesis. Heat stress is also known to decrease saliva production, which can affect the buffering capacity of the rumen. Reduced ruminal pH may reduce milk fat synthesis (Emery, 1978). The decrease in protein percentage could be also attributed to the direct effects of heat stress on the synthesis of mammary gland (Cowley et al., 2015). Exposure to higher THI decreased milk lactose levels supporting Nardone et al. (1997) and Shwartz et al. (2009). This can be due to direct and indirect effects of heat stress on the delivery of component precursors (namely glucose) to mammary gland ...

Heat stress can be fatal to dogs. Days with high humidity will make the dog pant, if heavy panting should last for an hour their throat will become swollen and his air intake will be restricted. If he gets to the point where the dog is making peculiar noises in their throat: tongue off-colour; convulsions; refuses to drink water or lick ice, the dog is in trouble and needs your immediate attention. Prolonged panting will produce thick froth or foam. In this the dog does not have the ability to vomit thus clearing their throat for better air intake. To clear the dogs throat you can reach in and pull out the thick mucus, or use lemon juice this cuts phlegm loose, causing the dog to vomit. The number one priority is to cool the dog down fairly rapidly. The head and neck should be cooled down firstly, so that blood going to the brain is cooled, in turn preventing brain damage and settling down respiration rate. Heat loss comes through places with minimal hair such as the dogs belly, anus, and ...

How to cope so that summer is great for both of you!. As we approach the hottest part of the summer, it is important to review some basic strategies that will help us avoid heat stress in horses. Often it is the summer months where we get the most enjoyment from spending time with our horses, but it is our job to make sure that we dont overdo it with them.. So what conditions might make our horses over heat? Obviously high environment temperatures are the key, but also prolonged or intense exercise, or inadequate hydration may all contribute to heat stress. Horses, just like us, dissipate the majority of their excess body heat through sweating. Horses have a tremendous ability to sweat, and can sweat as much as 10-12 liters per hour. Depending on the environmental temperature and the work load, it is possible for horses to become dehydrated in as little as 2-3 hours. Horses that have inadequate access to water will not be able to sustain the same sweating rate as a horse with proper hydration. ...

This study tested glycerol hyperhydration against water hyperhydration on the ability to reduce cardiovascular and thermal strain and improve performance when Ss ran a set distance as quickly as possible. It was hypothesized that compared with water hyperhydration, glycerol hyperhydration would result in: a) greater fluid retention, b) no differences in heart rates and core temperatures, and c) decreased run time performances. Male endurance trained runners (N = 6) completed a treadmill run in an environmental chamber at a self-selected pace, estimated to take one hour. Temperature was set at 30 C with 50% relative humidity. Beginning 2.5 hours before exercise, glycerol was given at 1.2 g/kgBW with a total fluid ingestion of 26 ml/kgBW. The placebo condition involved ingesting water of an equal amount. Runners ingested up to 500 ml during the run and were unable to see their elapsed time or chosen speed; only distance covered.. Fluid retention and time to complete the run were no different ...

Note: As the basic assessment is a qualitative assessment, instrumentation for measurement of wet bulb glove temperature (WBGT) is not mandatory meaning people with limited technical expertise and equipment can identify and assess the risk factors. The basic assessment can therefore be performed using readily available information at the workplace (i.e. ambient air temperature and relative humidity).. The online calculator is an initial qualitative review of potential heat stress situations and is not a definitive assessment tool.. A level 2 (technical) assessment will be needed when:. ...
