Heat Cramps Causes

The exact cause of heat cramps is unknown, but it is probably related to electrolyte problems. Various essential minerals, such as sodium, potassium, calcium, and magnesium, are known as electrolytes. They are important for many body functions, and an electrolyte imbalance can cause problems.

Sweat contains a large amount of sodium, and drinking fluids with inadequate sodium content after sweating profusely may result in a serious low-sodium condition called hyponatremia. Some factories have virtually eliminated heat cramps in their workers by supplying salt-enriched fluids.
