Heat is generated as a result of the constant chemical processes within the body. A certain amount of this heat is required to maintain normal body temperature. If allowed to go unchecked, this will lead to death. The individual perspires heavily, often drinking large quantities of water. As the sweating continues, salts are lost by the body, bringing on painful muscle cramps.
Some medical authorities question whether heat cramps are associated with salt loss.
This is a mild form of shock brought about by fluid and salt loss. Blood will pool in the skin as the body attempts to rid itself of excess heat. Heat exhaustion is more of a problem during the summer and reaches a peak during prolonged heat waves. The condition may develop into heat stroke. The problem is compounded when the patient fails to sweat in response to fluid and salt loss due to heat.
