Drink Cold Water, Burn Calories

In the summer, drinking cold water to cool off is a no-brainer, but recent research shows that it also can temporarily boost metabolism up to 40 percent.

Drinking 48 ounces of cold water daily can cause you to burn an extra 50 calories per day, which might not sound like much, but over the course of a year, that adds up to 5 pounds! Researchers theorize that you expend extra energy to bring cold water up to body temperature, which is why you don’t experience the same results from warm or hot water.
