If you’re not getting enough shut-eye, you may notice the effects on your bathroom scales.
Researchers at Case Western Reserve University in Cleveland, Ohio, studied the sleep habits of more than 68,000 middle-age women for 16 years. They found women who slept five hours or less per night were 32 percent more likely to gain excess weight—33 pounds or more—and 15 percent more likely to become obese than those who slept seven hours per night. Women were 12 percent more likely to pack on the pounds if they slept for six hours, and six percent more likely to become obese.
The weight gain occurred despite the fact that those who slept less seemed to eat less. Researchers say it could be that too-little sleep translates to extra pounds by interfering with metabolic rate.
