Drinking enough water is one of the simplest and most effective things you can do for your health. But how much water is enough? The answer depends on your weight, activity level, and climate.
In this article, we'll show you the formula, the influencing factors, and practical tips for your daily routine.
The Basic Formula
Water intake (liters) = Body weight (kg) × 0.033
Example: A person weighing 70 kg needs 70 × 0.033 = 2.3 liters per day as a baseline.
This value is then adjusted by activity and climate factors.
Influencing Factors
Physical Activity
More movement means more sweat and higher water needs. Light activity increases needs by 10%, intense activity by up to 40%.
Climate
Hot, humid environments increase water needs by about 20%. In cold climates, needs decrease slightly as less sweat evaporates.
Diet
A high-protein diet increases water needs because the kidneys require more water for processing. Fruits and vegetables provide additional water.
