Water temperature boils down to personal preference, but it might also support your body in more ways than you realize.
Ahead, our expert gives us the 411 on the benefits — and potential cons — of drinking cold water.
Drinking water regulates your body temperature, eliminates toxins, and keeps joints lubricated.
Though there isn’t scientific data to back up this theory, some experts feel that “drinking cold water can prevent toxin buildup and strengthen your immune system,” says Dr. Jenelle Kim, a doctor of Chinese medicine.
“Drinking cold water reduces the body’s core temperature, which causes blood vessels to restrict. Therefore, the body has to use more energy to bring the core temperature back to normal,” explains Dr. Kim.
When you’re running on low battery, the shock of cold water can temporarily have similar effects as caffeine by giving you an adrenaline jolt — helping you to concentrate and stay alert.
“Cold water is great at regulating your body temperature if you are in a hot climate or working out,” says Dr. Kim.
The cooler temperatures suppress any impurities that alter the taste of pure water — say, if you’re drinking tap in a location that has more minerals in the water. Those impurities are less detectable when water is cold.
