Heatstroke also known as sun stroke, is a type of severe heat illness that results in a body temperature greater than 40.0°C (104.0°F). There's generally a lack of sweating in classic heatstroke while sweating is generally present in exertions heatstroke.
The start of heatstroke can be sudden or gradual. Heatstroke is a life-threatening condition characterized by severe hyperthermia and multiorgan-dysfunction resulting from exposure to heat, present with a hyperthermia of greater than 40.6°C(105.1°F) in combination with disorientation. However, high body temperature does not necessarily indicate that heatstbody is present, such as with people in high performance endurance, sports or with people experiencing fevers.
Exertional heatstroke (EHS) is more accurately diagnosed based on a constellation of symptoms rather than just a specific temperature threshold. There is generally a lack of sweating in classic heatstroke, while sweating is generally present in exertional heatstroke.
Early symptoms of Heatstroke include behavioral changes, confusion, delirium, dizziness, weakness, agitation, combativeness, slurred speech, nausea and vomiting.
In some individuals suffering from exertional heatstroke, seizures, and sphincter incontinence have also been reported. Additional, in exertional heatstroke, the affected person may sweat excessively. The risk of heatstroke can be reduced by observing precautions to avoid overheating and dehydration. Light, loose-fitting clothes will allow perspiration to evaporate and cool the body. Wide-brimmed hats in light colors help prevent the sun from warming the head and neck. Vents on hat will help cool the head, as well as sweatbands wetted with cool water. Strenuous exercise should be avoided during hot weather, especially in the sun peak hours as well as avoiding confined spaces (such as automobiles) with air-conditioning or adequate ventilation. In hot weather, people need to drink plenty of cool liquids and minerals salts to replace fluids lost from sweating. Thirst is not a reliable sign that a person needs fluids. A better indication is the color of urine. A dark yellow color may indicate dehydration.
