How Much of the Body Is Water and its Significance for Singers

Izzy Gerosa
Have you ever wondered how much water we have in our body? Well, the amount of water does vary, depending on the organ in question. Blood plasma in particular, contains much of the water (20% of the body's total).

According to a study performed by H.H. Mitchell, published in the Journal of Biological Chemistry, the amount of water in the human heart and brain is 73%, the lungs are 83%, muscles and kidneys are 79%, the skin is 64%, and the bones are around 31%.

Therefore, the overall amount of water in the human body ranges from 50-75%,

And water serves multiple purposes. Water is the primary building block of cells. It acts as an insulator that regulates internal body temperature, partly because water has a high specific heat, and the body uses perspiration and respiration to regulate temperature.

Needless to say, in order for the body to metabolize proteins and carbohydrates from food, water is needed. It is the primary component of saliva, used to digest carbohydrates and aid in swallowing food.

Water lubricates joints and also insulates the brain, spinal cord, organs, and fetus. It acts as a shock absorber. And last but not least, water is used to flush waste and toxins from the body via urine.

That is the important role water plays in our body. So you can imagine how beneficial this is for our overall wellbeing, not to mention the vocal folds—and thereby our voice!
