What is different between heat stroke and heat exhaustion?

Answer 1

Heat Stroke

Caused By: Body cannot regulate its own temperature due to intensive sweating under conditions of high heat and humidity. Advanced age can be a factor.

Symptoms: Weakness, vertigo, nausea, headache, heat cramps, mild heat exhaustion, excessive sweating. Sweating stops just before heat stroke. Temperature rises rapidly (as high as 106 degrees Fahrenheit); blood pressure is elevated. Skin is flushed at first, then turns ashen or purplish. Delirium or coma is common.

First Aid: Heat stroke is a medical emergency. Call for medical assistance. Move person to a cool, indoor place. Loosen or remove clothing. Primary objective is to reduce body temperature, preferably by iced bath or sponging down with cool water until pulse lowers to below 110 per minute and body temperature is below 103 degrees Fahrenheit. Caution is necessary.

Heat Exhaustion

Caused By: Person does not get enough liquid and salt in very hot, humid weather.

Symptoms: Excessive sweating, weakness, vertigo, and sometimes cramps. Skin is cold and pale, clammy with sweat; pulse is thready and blood pressure is low. Body temperature is normal or sub-normal. Vomiting may occur. Although unconsciousness is rare, it may happen.

First Aid: Lay person in cool place. Give water to drink with 1 tsp. of salt to each quart of water. Fluid intake usually brings about full recovery. Get medical assistance if severe.
