This is a common question that I get in practice. Many people just aren’t sure how much water they should be drinking in a day. We’re going to keep it super simple here, and stick to the minimum: you should drink half your body weight in pounds in ounces of water in a typical day. On warm days where you spend a lot of time outside or exercise vigorously, you need more, but we’re just gonna stick with the basics and give you an example below.
To keep the math simple, we will take a person who is 160 lbs. Half of their weight weight in pounds is 80 pounds. They should drink 80 ounces of water. That translates to 10 cups of water a day or 4 20 oz water bottles.
Here’s an easy equation: [your body weight]/2 = ____ ounces of water.
____ ounces /8 = # of cups needed
____ ounces/20= # of water bottles needed
