The human body is composed of about 60% water. Drinking water helps maintain the balance of bodily fluids. Moreover, the functions of these bodily fluids include digestion, absorption, circulation, creation of saliva, transportation of nutrients, and maintenance of body temperature. Despite how crucial it is that people drink enough water, a significant amount of people tend to drink less than the recommended levels of fluids each day.

There are plenty of important reasons to drink water. The main reason is that drinking water is essential to replace the large amounts of water lost each day. When the water intake in the human body does not equal the output, the chance of dehydration increases. Moreover, fluid losses increase under specific circumstances, such as warmer climates, during strenuous exercise, in high altitudes, and in older adults, whose sense of thirst may not be as sharp.
