Water, it’s all around us and is even inside of us. The human body is predominantly made up of water, so it’s no secret that our bodies need water to thrive and function at their full capacity. Sadly though, many of us are not taking in as much water as we should be during the day. While many of us have heard the 8 glasses a day lecture as kids, how much water do our bodies actually need?

The Hydration Equation

The basic equation for determining just how much water your body actually needs is by dividing your body weight in half. So, if you weigh 140 pounds, you would need 70 ounces of water per day to keep your body fully hydrated. Keep in mind though that this equation is for your basic hydration needs, this number increases depending on your activity levels. So athletes beware, you need to be drinking far more than half your weight.

Why Hydration is Important

Simply put water is important because our bodies depend on water for survival. Every cell, tissue and organ in our body needs water to function. Water is also essential to good health, weight management, and even the quality of our skin.
