Cooler homes and a better night’s sleep could help curtail the current obesity epidemic, according to an Italian study.  When researchers at the University of Turin followed more than 1,000 middle-aged adults for six years, they found that the odds of these adults becoming obese declined by 30% for every hour of sleep they typically got. This was true even when other factors such as physical activity level and TV watching were taken into account, according to the study published in the International Journal of Obesity.
What was perhaps more surprising was the relationship between obesity and home temperature. The people who preferred to keep their homes toasty were twice as likely to become obese than those who kept their thermostats below 68 degrees F. Why? Apparently, you burn more calories when your body has to work harder to maintain its normal 98.6.  Temperature isn’t the answer to the obesity problem—there are obviously many factors—but turning down the thermostat wouldn’t hurt. And it has the added benefit of saving on energy bills.
