Is it Better to Drink Warm Water or Cold Water?

Drinking water is important for good health. Water helps carry nutrients through your body, flush toxins out of organs, and maintain the moist environment needed in mucus membranes like the nose and throat. In general, both warm and cool water are good for drinking, but you may wish to consider a few points.

Hydration

Warm and cold water are equally hydrating; the temperature of water does not affect your body's ability to absorb it.

Natural Preference

Most people are more inclined to drink cool or cold water than hot water--for this reason, cold water is recommended for hydration.

Tap Water

Hot water from the tap is never recommended. It can contain more heavy metals and other contaminants than cold water from the same tap.

Carbonation

Carbonated water is just as hydrating as plain water, but may limit your desire to drink due to effects on the stomach.

Effects on Illness

In the case of illnesses like the common cold or other respiratory infections, hot water is generally more beneficial. Research shows that it improves fluid management and mucus flow.
