May help digestion

Drinking water promotes the regularity of the digestive system. The body can better remove waste when the liquid passes through your stomach and intestines. Some people think that drinking hot water is especially effective for activating the digestive system.

According to the theory, hot water can help dissolve and eliminate food that your body may have had difficulty digesting. Although a 2016 study suggested that warm water could be beneficial for bowel motions and gas expulsion after surgery, more research is required to confirm this benefit. When hot water is drunk first thing in the morning, this benefit is most noticeable.
