How much water should I drink daily?

Daily water intake depends on factors like weight, activity level, climate, and health. A common recommendation is around 8 glasses (2 liters), but our calculator provides a more personalized estimate by taking these variables into account.

Is 4 liters of water a day too much?

For many active individuals, especially in hot climates, 4 liters (about 1 gallon) of water can be a healthy amount. However, for a sedentary person in a cold climate, it might be excessive. Extremely high intake (over 6-7 liters in a short period) can be dangerous. It's important to listen to your body and your thirst.

How do I calculate water intake by weight?

A common baseline formula is to multiply your weight in kilograms by 35ml. For example, a 70kg person would have a base need of approximately 2450ml (2.45 liters). Our calculator uses this as a starting point before adding adjustments for other factors.

Does climate affect hydration needs?

Yes, significantly. In hot or humid climates, you lose more fluid through sweat, so your water intake needs to increase to compensate. Our calculator adds an adjustment for hot climates to account for this.
