How many cups of water do you have to drink a day?

The amount of water you need to drink per day depends on a number of factors, including your age, activity level, climate, and overall health.

It's best to talk to a doctor or registered dietitian to determine how much water is right for you.

Here are some general guidelines, though:

* The National Academies of Sciences, Engineering, and Medicine recommends that men consume about 15.5 cups (3.7 liters) of fluids per day.

* For women, the recommendation is about 11.5 cups (2.7 liters) of fluids per day.

These recommendations include fluids from all sources, including water, juice, fruits, and vegetables.
