What is the role of hydration during exercise?

Hydration plays a crucial role during exercise, primarily to maintain body temperature and prevent dehydration. When engaging in physical activity, the body generates heat, and sweating becomes a mechanism for thermoregulation. Adequate fluid levels ensure that the body can cool itself effectively through perspiration. Without sufficient hydration, a person risks overheating, which can lead to heat-related illnesses.

Additionally, proper hydration helps maintain blood volume, which is essential for delivering oxygen and nutrients to working muscles. This process is vital not only for performance but also for recovery and overall well-being during and after exercise. Therefore, staying hydrated is essential not only for physical performance but also for maintaining safety during any form of exercise.
