Heat Stroke

Heat stroke is the most severe of all heat-related illness and could be life threatening.

Heat Exhaustion

Heat exhaustion is a heat related disorder. The loss of fluids takes place decreasing blood flow to vital organs, leading to shock.

Seek professional medical assistance if the symptoms don't clear up in 30 minutes. Seek emergency help in case of physical collapse or loss of consciousness.

Heat Cramps

Heat cramps are involuntary muscle spasms. They are caused by a deficiency of water and sodium in the body. Heat cramps are painful, may be severe and prolonged.

Heavy exercising in hot weather causes excessive sweating which leads to electrolyte deficiency resulting in muscle cramps.

Heat cramps are the least serious of all heat injuries. It is a warning sign for heat exhaustion.

Muscles most affected are the voluntary muscles of:

Calves
Arms
Thighs
Back
Abdomen

Heat Cramps are caused by:

Excessive sweating
Loss of body salts
Muscle stress
Poor body condition

Rapid heartbeat
Hot/sweaty skin

Treatment:

Rest briefly and cool down. Apply manual pressure and massage to the affected muscle areas. Drink one quart of water with one teaspoon of salt. Drink some clear juice or electrolyte-containing sports drink if available. Practice gentle stretching exercise of the affected muscle. Seek medical help if the cramps remain after 1 hour. Heat cramps usually improves with an electrolyte drink, cool shade and rest.
