Your body needs water, but the amount you need to drink varies from day to day. I designed this hydration calculator to help you decide how much water you need today. Answer all the questions based on how you feel and what your activity levels are today:
Note: there are some times when drinking too much water can be a problem:
If you have any kidney or adrenal problems, or your doctor has you taking diuretics, you need to consult with your doctor about how much water to drink each day
Don't drink all of the water you need per day all at once. Divide the amount you need and drink several glasses of water throughout the day. This is especially important if you engage in lots of heavy exercise.
Infants should be given only formula or breast milk unless your pediatrician tells you otherwise.
