Factors That Affect Your Water Needs at 50kg
Climate & Humidity
In hot climates (over 30°C/86°F), your body loses more water through sweat. Increase your daily intake by 400-600ml. High humidity also increases fluid loss.
Physical Exertion
During exercise, you can lose between 500ml to 2 liters of water per hour. Monitor your sweat rate and replenish fluids accordingly. Weigh yourself before and after workouts.
Health Conditions
Certain medical conditions, such as diabetes, and medications like diuretics, can increase fluid loss. If you have a health condition, consult your doctor about your hydration needs.
Dietary Choices
Foods with high water content (fruits, vegetables, soups) contribute to your daily fluid intake. Be mindful of caffeine and alcohol, as they can have a diuretic effect.
