Proper hydration during exercise is crucial for optimal performance and overall health. Staying hydrated helps regulate body temperature, maintain joint lubrication, and transport essential nutrients to cells. Dehydration can lead to fatigue, reduced coordination, and impaired exercise capacity. It also increases the risk of heat-related illnesses. Athletes should aim to drink fluids before, during, and after workouts to ensure their bodies maintain ideal moisture levels, enhancing endurance and recovery while preventing performance declines.
