After exercise, the body responds to hydration needs by increasing the sensation of thirst and triggering hormonal adjustments to maintain fluid balance. Proper hydration is crucial for recovery, as it aids in the transportation of essential nutrients and electrolyte replenishment. Drinking water post-exercise can help restore lost fluids, support muscle recovery, and improve performance in subsequent workouts. Dehydration can lead to decreased physical performance and increased recovery time, making hydration a critical component of any fitness regimen.
