How Much Water Should We Really Drink?

The classic question. How much water do we really have to drink?

It's funny. Think about how long we have been drinking water. We still don't know this answer.

If you asked the average person how much water they should drink, would they know? Most likely not. Some may give the generic 8 glasses (8 oz.) a day, others probably only drink when they are thirsty.

Our hydration status is important. Studies show that a drop in even 2% of our fluid intake can effect both physical and mental performance.

So is 8 glasses of water really enough?

Yes and no.

We are actually more concerned with our total fluid intake than just water. Water, tea, milk, soda would all be considered part of our fluid intake. Even drinks we consider dehydrating, such as coffee, actually add to our fluid intake more than take away from it. The only exception is alcohol, which is dehydrating.

General Rule for Daily Fluid Intake

- 2/3 of bodyweight (lb) in fluid ounces, or

- 1 liter for every 23 kg of bodyweight.

Example: 200 lb person should consume 133 fluid ounces a day.

*If you are a person who sweats a lot, live in a hot climate, or exercise for longer than an hour you need to drink more fluids. I would consider drinking 50% more fluids in these situations.

Even though we look at total fluids instead of only water, it is still a could idea to get most of your fluids from water. Drinking your calories is an easy way to pack on the pounds.
