Armstrong LE, Keeping the body cool can minimize the dilation of blood vessels and prevent the accumulation of fluids in the legs. Open your windows at night. The organs most affected by elevated core temperatures are the brain and liver,13 and prognosis is related to the time spent in hyperthermia. Excessive exercise, exposure to the high-temperature cloudy environment (more than 40deg C), confinement to closed working chamber, cars etc. / Journals See the CME Quiz Questions. Jardine DS. Casa DJ, 2018;22(3):392–397. Heat-Related Illnesses. Brown LM, 2007;39(3):556–572. 2011;128(3):e741–e747.

Casa DJ, Circulation Research, 52:367–9. Strenuous exercise combined with exposure to high ambient temperature effectively exceeds cardiac output, resulting in presyncopal symptoms, fatigue, malaise, gastrointestinal symptoms, cold and clammy skin despite heavy diaphoresis, and core body temperature of 101° to 104°F (38.3° to 40°C). It can cause several illnesses, all grouped under the name hyperthermia (hy-per-THER-mee-uh): If you have heat stroke, you need to get medical help right away.

Le QH, Exertional heat illness in adolescents and adults: epidemiology, thermoregulation, risk factors, and diagnosis.

Calvello EJ, Any decline in mentation, regardless of core temperature, must be considered heat stroke (in certain cases, core temperatures may actually increase). The incidence of heat-related illness in U.S. high school athletes is 1.6 cases per 100,000 athletic exposures, or approximately 9,000 cases annually, with the highest rates occurring during football season.9 It is the third leading cause of death in high school athletes.10 In the U.S. Armed Forces, there were 2,163 cases of heat-related illness and 464 cases of heat stroke in 2017, with an incidence of 1.41 and 0.38 cases per 1,000 person-years, respectively.11 The incidence has gradually increased since 2014. When cooling is completed within 30 minutes from collapse, the mortality rate approaches zero.26,27 Patients who present to the emergency department with a core body temperature of 105.8°F (41°C) or greater and prolonged hyperthermia have mortality rates as high as 80% (although this number includes patients with nonexertional heat stroke, which has a higher mortality rate).5,8, Drug toxicity (e.g., salicylates, stimulants), Systemic infection (e.g., sepsis, septic shock).

This condition occurs when the body starts to retain water and have trouble excreting salt. Khoujah D.

Supportive care involves moving the patient to an area of lower temperature if possible and elevation of the affected area to promote fluid drainage. Eifling KP, 2013;25(2):251–262. Ferry T, Grissom CK. Bergeron MF,

Environ Health Perspect. Transient orthostatic hypotension results from volume depletion, peripheral vasodilation, and decreased vasomotor tone, leading to syncope.14,21 Treatment is largely supportive. Moran DS, Imaging studies are not needed unless clinically indicated. Armstrong LE, Keep in mind: Electric fans may provide comfort, but when the temperature is in the high 90s, they will not prevent heat-related illness. Rethinking the cause of exercise-associated muscle cramping: moving beyond dehydration and electrolye losses. 2014;122(11):A293]. But if that doesn’t work, here are six other hacks to try.

Although, edema may also affect the face or other body parts also.Edema is caused by chronic u Pay attention to environmental conditions, especially the heat index/weather forecast. Gasparrini A, In some cases, X-rays, ultrasound exams, magnetic resonance imaging, blood tests or urine analysis may be necessary.
