5. Reduces Water Retention
Retaining water often shows up as swollen hands, feet, legs, and even your belly. Diuretics are often prescribed as a treatment for water retention. However, if you do not drink enough water this problem is not going to go away.
It may seem like drinking water to reduce water retention is contradictory, but if you are retaining water it is a sign of dehydration and drinking more water is what you need to do. Being adequately hydrated will reduce fluid retention.
You may also see a problem if you are eating too much salt. Drinking water can flush the excess salt from your system.
