Sleep Cooler, Burn More Calories

Sleeping in a cold room literally transforms your body while you rest. When your bedroom

temperature drops to around 66 degrees Fahrenheit, your body activates brown fat,

a special type of fat that burns calories to generate heat. This process can increase your metabolism

by up to 10 percent. Cold exposure also triggers the release of melatonin earlier in the evening,

which deepens your sleep cycles and helps repair cellular damage. Scientists found

that people who sleep in cooler rooms produce more growth hormone, which plays a crucial

role in tissue repair and slowing the aging process. The sweet spot is between 60 and 67

degrees. Your body works harder to maintain its core temperature, burning extra calories
