Sleep is essential for good health but a new study hints there may be an easy way to add to its virtues.
Researchers say the thermostat may be key to your health.
Experts say sleeping in a cool 66 degree room may actually double the amount of brown fat in our bodies, which is the so-called good fat that produces body heat.
Authorities say it is important because brown fat improves insulin sensitivity and reduces the risk of diabetes.
Researchers plan more studies to include overweight and diabetic patients.
