Drinking enough water is one of the most important things you can do for your body every day. Why is it then that so many of us suffer from chronic dehydration? 75% of Americans are chronically dehydrated. Most people are so used to being dehydrated that they no longer recognize the normal signal of thirst. We cannot go more than two to three days without water, although we can go weeks without food. The human body is about 60% water, your muscles and your brain are about 75% water, your blood is about 82% water, and your bones are about 25% water. Water is required for everything from regulating blood pressure and body temperature to making sure your heart works correctly and that your brain is capable of doing its daily tasks.
When our bodies become dehydrated, the thirst mechanism can often be disguised as hunger. This may be a contributing factor to our obesity epidemic. One glass of water shut down midnight hunger pangs for almost 100% of the dieters studied in a University of Washington study.
When our body is dehydrated it doesn’t work as efficiently, even mild dehydration will slow down one's metabolism as much as 3%. Slower metabolism means more fat stored and less used as fuel for your body.
