Factors That Affect Your Water Needs at 65kg
Environmental Temperature
Higher temperatures and humidity lead to increased sweating and fluid loss. Increase your water intake by 400-600ml on hot days, especially during outdoor activities.
Physical Exertion Levels
Exercise increases water loss through sweat. For every 30 minutes of moderate exercise, add an extra 350-700ml of water. Adjust based on sweat rate.
Underlying Health Conditions
Certain health conditions, such as diabetes, kidney problems, or infections, can affect fluid balance. Consult your doctor for personalized hydration advice.
Dietary Habits & Choices
Consuming salty foods, alcohol, or caffeinated beverages can increase fluid loss. Counteract these effects by drinking an extra 250ml of water per serving.
