How many glasses of water to drink depending on your weight?

A common guideline is to drink half your body weight in ounces of water daily. For example, if you weigh 160 pounds, you should aim for about 80 ounces of water, which is roughly 10 glasses (assuming a standard 8-ounce glass). Individual needs may vary based on activity level, climate, and health conditions, so it's important to listen to your body's thirst signals as well.
