Heat stroke
en.wikipedia.org/wiki/Heat_stroke
Heat stroke or heatstroke, also known as sun-stroke, is a severe heat illness that results in a body temperature greater than 40.0 °C (104.0 °F),[4] along with red skin, headache, dizziness, and confusion.[2] Sweating is generally present in exertional heatstroke, but not in classic heatstroke.[5] The start of heat stroke can be sudden or gradual.[3] Heatstroke is a life-threatening condition due to the potential for multi-organ dysfunction,[6] with typical complications including seizures, rhabdomyolysis, or kidney failure.[3]
Heat stroke occurs because of high external temperatures and/or physical exertion.[3][4] It usually occurs under preventable prolonged exposure to extreme environmental or exertional heat.[6] However, certain health conditions can increase the risk of heat stroke, and patients, especially children, with certain genetic predispositions are vulnerable to heatstroke under relatively mild conditions.[7]
Preventive measures include drinking sufficient fluids and avoiding excessive heat.[8] Treatment is by rapid physical cooling of the body and supportive care.[4] Recommended methods include spraying the person with water and using a fan, putting the person in ice water, or giving cold intravenous fluids.[4] Adding ice packs around a person is reasonable but does not by itself achieve the fastest possible cooling.[4]
Heat stroke results in more than 600 deaths a year in the United States.[4] Rates have increased between 1995 and 2015.[3] Purely exercise-induced heat stroke, though a medical emergency, tends to be self-limiting (the patient stops exercising from cramp or exhaustion) and fewer than 5% of cases are fatal. Non-exertional heatstroke is a much greater danger: even the healthiest person, if left in a heatstroke-inducing environment without medical attention, will continue to deteriorate to the point of death, and 65% of the most severe cases are fatal even with treatment.[3]
