(Health.com)It doesn't take much to become dehydrated. Lose just 1.5% of the water in your body (the human body is usually about 60% H2O), and you've reached the tipping point of mild dehydration. It can be brought on by many things — and it can do much more to your body than just make you feel thirsty. Dehydration also brings on health effects ranging from fatigue and smelly breath to more dangerous consequences like distracted driving.
