Do the math

Oftentimes, people don’t realize they’re dehydrated until it’s too late. Stay ahead of your thirst by drinking throughout the day. A simple formula to use: Divide your weight in half and that’s about how many ounces of fluids you should aim for daily. If you weigh 160, you need 80 ounces or 10 (8-ounce) glasses each day. Keep in mind that you need a little more in the warmer months or when you’re more active.
