Drinking water is essential to our health. We must replenish the fluids that we lose through sweat, urination, tears, etcetera, or we become dehydrated. Extreme dehydration leads to death. As I am sure everyone has heard before, our bodies are about 60-70% water. To maintain the proper balance of body fluids, which are responsible for absorption, digestion, metabolism, circulation, transporting nutrients and waste products, and maintaining body temperature, we must stay hydrated. You already probably know that when your urine is light and free of odor, you are staying properly hydrated, but when your urine is dark and there is odor, you are dehydrated and need to drink more water.
