Veelgestelde vragen
How much water should I drink per day?
Most adults need between 2 and 3.5 litres per day. The exact amount depends on body weight, activity level, and climate. A solid baseline is 35 ml per kg of body weight — this calculator applies that formula plus adjustments for your lifestyle.
Can you drink too much water?
Yes. Drinking excessive amounts very quickly can cause hyponatremia (dangerously low blood sodium). For healthy adults, drinking more than 1 litre per hour over an extended period is risky. Spread your intake evenly throughout the day.
Does coffee or tea count toward my daily water intake?
Moderate amounts of coffee and tea do count. The mild diuretic effect of caffeine is largely offset by the water content of the drink. That said, plain water is still the most efficient source of hydration and has no downsides.
Does drinking more water help with weight loss?
Drinking water before meals can reduce calorie intake by increasing feelings of fullness. Good hydration also supports metabolism and helps distinguish hunger from thirst. Water has zero calories and is one of the easiest free changes you can make.
