How are heat cramps primarily treated?

Heat cramps occur due to excessive sweating, which leads to a significant loss of electrolytes, particularly sodium. When the body loses sodium, it can result in cramps due to an imbalance in hydration and electrolytes. Therefore, the primary treatment for heat cramps focuses on replenishing electrolytes, and sodium intake plays a crucial role in this process.

While hydration with water is important to prevent further dehydration, it may not effectively address the underlying electrolyte imbalance that causes heat cramps. Cold compress applications and resting in a cool area can alleviate discomfort and prevent overheating but do not directly replenish the lost sodium, which is essential for muscle and nerve function. Thus, sodium intake stands out as the most effective treatment for resolving the cramps associated with heat-related issues.
