Getting Enough Sleep?

According to a new study on WebMD, if you are trying to lose weight, a good night's sleep may help. This study, presented May 15-20 at the American Thoracic Society's International Conference in San Diego, had participants wear armbands that measured total activity, body temperature, body position, and other indicators of rest and activity.

Contrary to what was expected, the overweight participants were significantly more active and burned more calories per day than their normal-weight peers.

Lead researcher Am Eliasson, MD, said, "We found so many interesting links in our data. Primarily, we want to know what is driving the weight differences, and why sleep and weight appear to be connected."

Lack of sleep may disrupt natural hormonal balances that trigger overeating. Stress could also be a factor according to Eliasson. For more on sleep and weight, see "Healthy Eating & Diet".
