What are heat cramps?

Heat cramps are defined as severe muscle cramps that typically occur in large muscle groups, especially after intense physical activity in hot weather. These cramps often result from excessive sweating, which can lead to an electrolyte imbalance and dehydration. When the body loses sodium and other essential minerals, it can trigger painful contractions in muscles that are heavily used.

Understanding this condition emphasizes the critical importance of hydration and electrolyte replenishment in preventing heat-related illnesses during vigorous activities, particularly in military settings where physical exertion in heat is common. Recognizing the specific characteristics of heat cramps helps in identifying and managing the condition effectively, ensuring the safety and health of personnel in field operations.
