We are composed of 70% water. We need water in order for our blood to circulate, our oxygen to flow, and our nerves to conduct electricity. Feeling thirsty is the first sign of dehydration. Hunger, difficulty concentrating, fatigue, and headaches are good indicators that you are dehydrated. You should be urinating every hour or two and the urine should be nearly clear.

So the Challenge Of The Week is to increase your water intake to match the general rule above for seven days and notice what changes in your health and energy level.
