FAQ
How much water should I drink daily?
A common guideline is about 33ml per kilogram of body weight. More active lifestyles and hot weather require increased intake.
Does coffee count toward water intake?
Caffeine has a diuretic effect, so caffeinated drinks don't fully count. Extra water is recommended when consuming caffeine.
Is it better to sip throughout the day?
Yes. Drinking large amounts at once reduces absorption efficiency. Spread your intake evenly across active hours.
