Water makes up about 60% of your body weight. Losing just 2% of your body's water content can significantly impair physical performance and cognitive function.Factors Affecting Hydration
- Body Size: Larger people need more water.
- Exercise: You need to replace the fluid lost through sweat. A rough rule is to drink an extra 12 oz (350ml) for every 30 minutes of exercise.
- Environment: Hot or humid weather increases sweat rates requiring more fluid intake.
