Quick Answer
Heat exhaustion is different from heatstroke in that it is a less severe condition where the body is still able to cool itself through sweating, but the body is unable to cool itself effectively. In heat exhaustion, the body temperature is typically near normal, and sweating is profuse. Heatstroke, on the other hand, is a life-threatening condition where the body temperature rises rapidly, causing damage to the brain and other organs.
Understanding Heat Exhaustion and Heatstroke
Heat exhaustion is characterized by symptoms such as heavy sweating, pale or flushed skin, fast and weak pulse, nausea or vomiting, dizziness or fainting, and headaches. These symptoms can develop within a few minutes to a few hours of exposure to high temperatures, particularly in individuals who are not acclimated to the heat. Treatment for heat exhaustion typically involves moving the individual to a cooler location, removing excess clothing, and providing cool water to drink.
Recognizing Heatstroke
Heatstroke, a medical emergency, is characterized by symptoms such as high body temperature, confusion, agitation, and loss of consciousness. The body temperature can rise as high as 106°F (41.1°C) in a matter of minutes. Heatstroke can also cause seizures and coma, and if left untreated, it can be fatal. If you suspect someone has heatstroke, call for emergency medical help immediately.
Field Treatment for Heat Exhaustion and Heatstroke
In emergency situations, field treatment for heat exhaustion and heatstroke involves rapidly cooling the individual. This can be done by applying cool water to the skin, using a cooling blanket or towel, and providing cool water to drink. Remove excess clothing, and provide shade or a cool environment. If the individual is conscious, have them drink 1-2 cups of cool water each hour. Monitor their temperature and symptoms, and seek medical help if they do not improve within 15-30 minutes.
