Want to lose weight? Keeping your bedroom cool may help, according to an article published in the New York Times. A study published in the journal Diabetes found that keeping bedrooms chilly can stimulate the body to produce more brown fat — the good fat — which burns white fat. On the other hand, warm temperatures reduce the amounts of brown fat in the body.
Researchers associated with the National Institutes of Health asked healthy young male volunteers to eat calorie-controlled meals and to sleep in climate-controlled bedrooms for four months. For one month, sleeping temperatures were kept at 75 degrees, a temperature considered neutral. The second month, temperatures were lowered to 66 depress. The third month, temperatures were reset to 75 again, and for the fourth month, temperatures were raised to 81 degrees. At the end of each month, amounts of brown fat were measured.
After sleeping at 66 degrees for one month, the men's amount of brown fat had almost doubled, they had burned more calories during the day, and their blood sugar had improved. But after sleeping for a month at 81 degrees, the men had less brown fat than they had at the beginning of the study.
"These were all healthy young men to start with," study author Francesco S. Celi told the New York Times, "but just by sleeping in a colder room, they gained metabolic advantages." Those advantages could include keeping weight in check which would decrease the risk for metabolic problems including diabetes.
