Frequently Asked Questions
How are daily water needs determined?
As a general rule, a consumption of 35 ml of water per kilogram is recommended. Additionally, this amount is increased in cases of physical activity or hot weather to replace fluids lost through sweating.
Do tea, coffee, or juices replace water?
While other beverages contribute to fluid intake, caffeinated drinks like tea and coffee can have a diuretic effect. Pure water is the best source for body hydration.
