How Much Water Do We Need Daily?

So how much water do we need daily anyway? Some say eight 8- ounce glasses (or 64 ounces), some say half your body weight in ounces and some are even foolish enough to say that we don’t need more than 1-2 cups.

Well, The Institute of Medicine determined that an adequate intake (AI) for men is roughly 3.7 liters (about 15 cups) of total beverages a day. The AI for women is 2.7 liters (about 11 cups) of total beverages a day. But as you can see they said “total beverages” with no mention of water exactly. So does that mean we can drink 11-15 glasses of juice, soda or sweet tea and be good? NO!! Even though foods and all beverages can add to your total fluid intake there is no substitute. We still need water, plain old water. Although the “8 by 8″ rule (eight-8 ounce glasses) isn’t supported by hard evidence as well as the exact amounts for everyone isn’t specific due to different lifestyles (exercise, pregnancy etc.), the “8 by 8″ rule remains popular because it’s easy to remember and it’s a good place to start.

Now as we work to increase our total intake of water daily, try not to drink all of your water in one sitting. Consuming water in 8-12 ounce increments throughout the day helps your body to utilize it better and not overwhelm your system all at once.

So wherever you are in your daily water intake let’s be mindful of the actual ounces we are taking in and work towards at least 64 ounces a day!
