Helps the body perform optimally
Bodily health will suffer if you do not drink enough water. This is especially crucial if you are active and exercise frequently, or if you live in an extremely boiling hot climate. Dehydration of 2% of body fluids can have significant consequences. Dehydration causes the body's temperature regulation to shift. You also feel less motivated and more tired. It also makes it more difficult to exercise and execute everyday tasks, both physically and psychologically.
Adequate rehydration has been demonstrated to avoid such occurrences. It even lessens the pressure to consume more oxygen during strenuous activity. Because muscles are composed of around 80% water. So, if you're active and sweat a lot, staying hydrated might help you maximize your performance and productivity.
