The human body is 80% water.
We need to drink at least 1/2 our body weight in ounces of water per day to maintain proper hydration.
Water regulates the temperature of the human body, carries nutrients and oxygen to cells, cushions joints, protects organs and removes harmful toxins from the body.
Dehydration slows down the body's metabolism.
Improper hydration causes daytime fatigue.
A mere 2% drop in body water can trigger fuzzy short term memory, trouble with basic math problems and difficulty focusing.
