Heat cramps are a specific type of heat injury that occur as a result of prolonged physical activity in high temperatures, leading to painful muscle contractions. These cramps usually manifest in the muscles that are heavily used during the exertion, such as the legs and abdomen.

The underlying cause of heat cramps is often a combination of dehydration and an imbalance of electrolytes like sodium and potassium, which are lost through sweat. As the body tries to cool itself through perspiration, the loss of these essential minerals can lead to involuntary muscle spasms.

It is important to recognize heat cramps because they can be a sign that the body is experiencing stress from heat, and they can progress to more severe heat-related illnesses if not addressed. Prompt treatment typically involves resting in a cool area, rehydrating with fluids, and replenishing electrolytes.
