Water is of major importance to all living things; in some organisms, up to 90% of their body weight comes from water. Up to 60% of the human adult body is water (source: water.usgs.gov).

According to H.H. Mitchell, Journal of Biological Chemistry 158, the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.

According to the Institute of Medicine (IOM), an adequate intake for men is approximately 3 liters a day and for women around 2.2  liters. 

Water regulates our body temperature, moves nutrients through our cells, keeps our mucous membranes moist and flushes waste from our bodies. Our lungs are 90 percent water, our brains are 70 percent water and our blood is more than 80 percent water. Simply put, we can't function without it. Most people sweat out about two cups of water per day (0.5 liters). Each day, we also lose a little more than a cup of water (237 ml) when we exhale it, and we eliminate about six cups (1.4 l) of it. We also lose electrolytes - minerals like sodium and potassium that regulate the body's fluids. ( Source: science.howstuffworks.com).

Essential functions of water in our body:

  • A vital nutrient to the life of every cell, acts first as a building material.
  • It regulates our internal body temperature by sweating and respiration
  • The carbohydrates and proteins that our bodies use as food are metabolized and transported by water in the bloodstream
  • It assists in flushing waste mainly through urination
  • acts as a shock absorber for brain, spinal cord, and fetus
  • forms saliva
  • lubricates joints
