Hydration

Hydration refers to maintaining adequate fluid levels in the body, crucial for optimal physiological function. It affects blood volume, temperature regulation, and muscle function. Dehydration can impair performance, causing fatigue, cramps, and heat-related illnesses. Runners should drink water before, during, and after exercise, adjusting intake based on intensity, duration, and climate. Electrolyte-rich drinks can replenish lost salts during long runs. Proper hydration enhances endurance, recovery, and overall performance. Real-world examples include marathon runners using hydration stations and carrying water bottles or hydration packs to ensure consistent fluid intake during races.
