Importance of drinking water

without comments

Human beings need water to survive and carry out their day to day activities. Below we will see why water is essential for survival.

It is necessary for the proper function of the brain. A large percent of the brain nearly 90% is water. When the body is denied water, brain functioning is inhibited. Consequently, leads to one suffering from migraine. Other cells in the body as well require water to function effectively.


Water acts as a medium of transporting nutrients to the body. Since it is a solvent, the nutrients in food dissolve in it and are distributed throughout the body. Water is the medium in which protein digestion takes place for the nutrients to be solely absorbed into the body.

Regulation of body temperature is the other function of water. This occurs in different ways. First, through sweat whereby water evaporates from the body. This brings about a homeostatic cooling effect to the body as well as toxic removal. Also, it is a good storage of heat which ensures temperature balance in the body.

Furthermore, it protects vital organs like spinal cord in the body by acting as a lubricant. This reduces the chances of arthritis and back pain. Organs like the eyes are protected against shock which can cause damage.

Re-hydration is the other purpose of water. We lose a lot of water through sweating urination and diarrhea. Due to the vigorous activities in our day to day activities, we tend to lose water which should be replenished. It is, therefore, advisable to take water to restore the lost fluids.

Lastly, it helps in digestion. When the food is broken down, water is needed to dissolve the minerals and some other nutrients. Some vitamins need to dissolve in water in order to be transported to the target organs.
