Drink more water. Adults should drink 2–3 liters (0.53–0.79 US gal) (or roughly eight 8 oz glasses) of water per day, while children should drink 1–2 liters (0.26–0.53 US gal) (or roughly five 8 oz glasses). That is in addition to other drinks like tea or coffee. Water keeps your body at the correct temperature and removes toxins and maintains homeostasis. Water also clears your skin, helps your kidneys, helps to control your appetite, and keeps you energized.It also keeps you from drinking unhealthy beverages like soda and juice, which are high in calories. The body barely registers the intake of these unhealthy drinks and yet you still feel thirsty hundreds of calories later. Drinking hot water (aka tea) can help stimulate your digestive system. Hot water also helps your body naturally detoxify itself. Make sure the water is comfortably hot and won't burn you.
