Why drink enough water?
Water affects every function in your body: temperature regulation, nutrient transport, joint lubrication, and tissue protection. Even mild dehydration (1-2%) reduces focus, energy, and athletic performance.
General rule: 35 ml per kg of body weight. Athletes need more due to sweat. If you drink coffee or sweet tea, increase water intake. Log daily to track your weekly pattern.
