Hydration Calculator

Your body weight is a primary factor in determining base water needs. Typically, you need 30ml of water per kg of body weight.

Age and gender can influence hydration needs due to differences in body composition and metabolic rates.

Higher activity levels increase water loss through sweat, requiring additional hydration to maintain balance.

Extended exercise sessions require extra water intake. Add approximately 500ml per hour of exercise.

Hot or humid environments increase sweating and water loss, while cold climates may reduce thirst signals.

Certain health conditions may require adjustments to water intake. Always consult healthcare providers.
