Researchers are yet to establish a connection between hot water and constant improvements in circulation. Even brief improvements in circulation can support better blood flow to muscles and organs.

Fighting colds and improving sinus health
Hot water can help to get rid of colds since heat applied to the sinuses can alleviate pressure caused by colds and nasal allergies. Drinking hot water helps unclog the sinuses and help free and quick movement of mucous.

Hot water improves circulation and blood flow, especially to injured muscles. No research has linked the consumption of hot water to pain relief. But some people regularly use heat packs and hot water bottles to ease pain and discomfort. Drinking hot or warm water may help relief internal pains, including menstrual cramps and pains.
