Are you tired or really just dehydrated?

One study conducted by Loughborough University found that a mere 5% drop in water levels in the body can cause a 25-30% loss in energy. Even a 3% drop can cause fuzzy thinking, “brain fog” and a slower metabolism. Another study conducted by University of Connecticut’s Human Performance Laboratory found that even a 1.5% water loss led to reduced cognitive function, headaches and fatigue in 25 women and 26 men.

So how much water should you be drinking?

It’s an individual thing, as water requirements vary from person to person. The amount of water we need depends on a number of factors, including our size, activity level, stress level, the climate or temperature and our diet. A good basic rule of thumb is to take your body weight (in pounds) and divide it by 2. This is the number of ounces of water that you should be drinking each day. For example, if you weigh 150 pounds, you will need 75 ounces of water per day. Divide this by 8 to get the number of 8-ounce glasses you should be drinking.
