how much glass water should i drink
The Institute of Medicine determined that an adequate intake (AI) for men is roughly about 13 cups (3 liters) of total beverages a day. The AI for women is about 9 cups (2.2 liters) of total beverages a day. Everyone has heard the advice, Drink eight 8-ounce glasses of water a day.. That's about 1.9 liters, which isn't that different from the Institute of Medicine recommendations. Although the 8 by 8 rule isn't supported by hard evidence, it remains popular because it's easy to remember.
So, if you weigh 200 pounds, you would need 100 ounces of water per day if you're not doing anything strenuous. If you're working out, hiking, at a high altitude or outdoors a great deal, you're going to need to add to those 100 ounces. When you don't get enough water, every cell of your body is affected.
