The Functions of Water In The Body
- Transports nutrients through the body
Once a substance is dissolved in water, water becomes vital for transporting it throughout the body. Blood - which is 83% water - transports oxygen, CO2, nutrients, waste products and more from cell to cell. Urine is also mostly water. Another very important transporter, urine removes waste products from the body.
- Moistens eyes, mouth and nose
Water is needed for protection as well. It keeps your mouth moist and washes away dirt and grime on your eyes. Water even lubricates our joints, keeping them from getting stiff and making sure motion is smooth.
- Can help maintain pH and electrolyte balance
Our bodies must maintain a very specific pH level of 7.4. pH values of less than 6.9 or greater than 7.6 are life threatening so it is essential that we have ways to keep pH from deviating too far from normal. Water is a reactant within a very important reaction that maintains pH at 7.4.
- Participates in many chemical reactions
As a chemical reactant, water is involved in many processes and pathways of the body. We use it to digest food in the gastrointestinal tract, to access stored energy for muscles and organ systems, and for countless other reactions.
- Helps maintain normal body temperature
Serves as a shock absorber inside the spinal cord and in the amniotic sac surrounding the foetus.
- Reduces chances of kidney stones
Increased water intake appears to decrease the risk of kidney stones.
- May reduce cancer risk
There are some studies showing that those who drink more water have a lower risk of bladder and colorectal cancer, although other studies found no effect.
- May reduce constipation
Increasing water intake can help with constipation.
