Hydration has a profound effect on physical performance and recovery. This study explores how much water we need, especially during activity.
Water is essential for blood flow, detoxification, and joint lubrication.
Dehydration slows tissue repair, reduces cognitive function, and increases pain sensitivity.
Active people need more than the average 2 liters/day.
