Overuse of water, wastage of water, increasing global population, water pollution, shortage of infrastructure, effects on the weather for climate change are the main causes that trigger water shortage. While the demand for usable water is not going to decrease, we have to conserve water and stop water pollution from our ends.

What Does Water Do For The Body?

Water helps to drive the vital functions of the body. From creating saliva in the mouth, digesting food to helping excrete the body waste, water is needed for every physiological function.

Water boosts up the metabolism rate and helps your body to absorb nutrients from the food. Keeping hydrated also affects the energy level and performance of the brain significantly.
