It is a fairly well known fact that the human body is comprised mainly of water. Most of the body’s vital organs are primarily water. The lungs are around 83% water, the heart is approximately 73% water and even skin is about 64% water. In fact, approximately 55-60% of the entire human adult body is made up of water. As a result, the human body craves water, and it must be hydrated on a constant basis in order to maintain a whole host of bodily functions. Water is needed for relatively simple functions such as forming saliva to aid in digestion, as well as lubricating the various joints throughout the body. Water is also critical to brain functions such as the manufacture of hormones and neurotransmitters, and acting as a shock absorber for the brain and spinal cord. With regard to system regulation, water helps to flush the body of waste products, especially in the form of urine, helps to regulate body temperature via sweating, and keeps the body’s mucosal membranes moist. Two of its most important functions are not even visible to the naked eye. Helping to deliver oxygen throughout the body, and allowing cells to grow and reproduce.

A decrease in body water by as little as 2% will affect coordination and concentration and can cause headaches or even cramping. Higher dehydration levels of 3-4% will result in physiological changes such as increase body temperature and heart rate, and at the very worst delusions.
