Cramps are caused by the loss of body salts and fluid through heavy sweating and high effort.
Types of heat loss in the body. Losses occur when heat transfers from the heated body surface to cooler surfaces and objects not in direct contact with the body.

EVAPORATION When you sweat or when your skin or clothing gets wet the evaporation of that liquid ie the change from liquid to vapour form promotes heat loss and the natural result is a cooling effect. To combat this drink plenty of. By just being alive we create a normal body temperature of 986F.

During intense exercise the body loses 85 of its heat through sweating.
Heat Loss Through the Head and. It occurs in conditions of extreme heat and excessive sweating without adequate fluid and salt replacement. Heat Loss Through Conduction.
The heat generated from within the body is given-off to the surrounding atmosphere. Loss of heat from the body surface to a cooler solid surface not in direct contact but in relative proximity. However the transfer of energy as heat occurs at the molecular level as a result of a.
When a muscle has a low salt level it cramps.
