SummaryThe human body is composed of 50-80% water. Blood and muscles contain significant amounts, and approximately 95% of the brain is water. All body systems and organs need water to function properly, and will shut down without it. Most of the chemical reactions that take place in our body need water as their medium. Water is vital to life. We can live without food for a few weeks, but can survive only several days without water. It’s essential because unlike other nutrients, water isn’t stored in the body. Typically, everyday, we lose around 10 cups of water, just living; urinating, perspiring and breathing.
