What is the condition involving muscle spasms due to excessive heat exposure?

The condition characterized by muscle spasms that result from excessive heat exposure is known as heat cramps. This typically occurs during physical exertion in high temperatures or humidity, leading to an imbalance of electrolytes in the body, especially sodium or potassium. As the body loses fluids through sweating, the muscles can begin to spasm as a reaction.

In heat cramps, individuals often experience painful cramps in the muscles, particularly in the legs and abdomen. It is a signal that the body is stressed due to heat and dehydration, which requires prompt attention to rehydrate and replenish lost electrolytes.

Understanding this condition is important because it serves as an early warning sign before more severe heat-related illnesses, such as heat exhaustion or heat stroke, develop. Identifying heat cramps and treating them appropriately can prevent the escalation to more serious conditions.
