When Should a Heat-Tolerance Test Be Scheduled After Clinical Recovery From an Exertional Heat Illness?

When Should a Heat-Tolerance Test Be Scheduled After Clinical Recovery From an Exertional Heat Illness? J Athl Train. 2020 Jan 27;: Authors: Schermann H, Hazut-Krauthammer S, Weksler Y, Spitzer S, Epstein Y, Kalmanovich G, Yanovich R Abstract OBJECTIVE: Researchers have produced a hypothesis of transient heat intolerance (HI) after exertional heat stroke (EHS). Based on this hypothesis, heat-tolerance testing (HTT) has been postponed until weeks 6 to 8 after EHS and other types of exertional heat illness (EHI). We compared the HTT results of participants after either EHS or other EHI who were tested earlier (6-week group) to verify the hypothesis. DESIGN: Cohort study. SETTING: Data obtained from records of military athletes who experienced EHS or EHI. PATIENTS OR OTHER PARTICIPANTS: All participants who underwent HTT after EHI or EHS experienced between 2014 and 2018 and for whom complete data regarding the severity of the event (rectal temperature, neurologic symptoms, and laboratory results) and HTT results were available were included. Participants with suspected EHS and those with other EHI were evaluated separately. MAIN OUTCOME MEASURE(S): The percentages of participants with HI and mean probability of heat tolerance were compared between those tested within 6 weeks of the event and those tested later. RESULTS: A total of 186 participants were included in this study (EHS: 12 in the 6-week group; EHI: 94 in the 6-week group...

Conclusions: Although HSRs exhibited a good understanding of heat-related health issues, stakeholders should improve the implementation of specific countermeasures on the workplaces.

(CNN) — Ending your day with a hot bath might have more benefits than just relaxation. It could also lower your risk of heart disease and stroke, a new study finds. Previous research on bathing has already shown that it’s beneficial for sleep quality and how healthy a person thinks they are. A new study, published Tuesday in the journal Heart, found that a daily hot bath is also associated with a 28% lower risk of heart disease, and a 26% lower risk of stroke — likely because taking a bath is also associated with lowering your blood pressure, the researchers said. They discovered this after tracking the b...

Authors: Ko WC, Lin CH, Lee JJ, Chang CP, Chao CM Abstract We aimed to ascertain whether therapeutic hypothermia (TH) acts as cardioprotective management for heat stroke (HS). Adult male rats under general anesthesia were exposed to whole-body heating (43°C for 70 min) to induce HS. Rats with HS displayed hyperthermia (core body temperature 42°C vs. 36°C); hypotension (30 mmHg vs. 90 mmHg mean arterial blood pressure); suppressed left ventricular (LV) performance (stroke volume 52 μl/min vs. 125 μl/min), ejection fraction (0.29% vs. 0.69%), relaxation factor (72 ms vs. 12 ms), and arterial elastan...

In this study, researchers analyzed temperature recordings from three periods of time over 157 years: 1860–1940: A mix of armpit and oral temperatures of nearly 24,000 veterans of the Civil War were measured. 1971–1975: Oral temperatures of more than 15,000 people from a large population study (the National Health and Nutrition Examination Survey) were analyzed. 2007–2017: Oral temperatures of more than 150,000 people in another large research project (the Stanford Translational Research Integrated Database Environment) were reviewed. During the nearly 160 years covered by the analysis, the average oral...

The incidence of heat-related illnesses is likely to increase with the intensification of global warming.1-3 For instance, more than 70,000 deaths were attributed to the 2003 European heat wave,4 and 55,000 deaths occurred in the unprecedented 2010 Russian heat wave.5 Both exposure to high temperatures and excessive heat production during strenuous exercise can result in heat-related illnesses.1,6 Heat stroke (HS) represents the most severe heat-related illness and is classically characterized by a high core temperature (> 40  °C) and central nervous system abnormalities such as delirium and convulsions.
