Everyone’s looking for home remedies for a stuffy nose—so give a drink of hot water a try. It may help alleviate some of the symptoms of a respiratory tract infection, says Nesochi Okeke-Igbokwe, MD, MS. Clinical trials suggest that drinking hot water benefits nasal congestion quicker than drinking cold water does because the higher temperature speeds up the rate at which mucus may travel. “The temperature of fluids we drink may possibly make a difference in the way we manage and deal with certain upper respiratory infection symptoms,” says Dr. Okeke-Igbokwe. Here are the 9 things that happen to your body when you drink enough water.
Easier on your teeth
Your teeth may thank you for switching from cold to warm water. According to Sanda Moldovan, MS, DDS, warm water is better for the teeth and restorations, and is more easily absorbed. “Certain white filling materials contract in response to cold water, causing fillings to debond off the tooth,” explains Moldovan. Again, make sure your water isn’t too hot. Any extreme temperature on the teeth can be detrimental, so try to drink your water at room temperature to keep your pearly whites happy.
Better for digestion
Warm water has a vasodilator effect, meaning it widens the blood vessels and stimulates the blood flow to rush toward the intestine, aiding the digestive process. “Drinking it on an empty stomach in the morning speeds right through your digestive system to the bowels where it is needed,” says cardiologist Luiza Petre, MD. But the digestive health benefits of warm water don’t stop there. It has a faster hydrating effect, so when it is followed by a meal the temperature helps emulsify fats, making them more digestible. Here are some weird facts about the digestive system you might not know.
