Lose Weight by Sleeping More
Sleeping in wonâ€™t make you fat. In fact, a new study shows that more hours in the sack could help you slim down by reducing how much control your genes have on your weight.
The study, published in the journal Sleep, looked at the sleep patterns and body mass indexes of more than 1,000 twins. On average, the people in the study slept 7.2 hours a night, which falls within the National Sleep Foundationâ€™s recommended 7-9 hours. People who slept less than seven hours a night, however, had a higher BMI than those who slept more than nine hours. Genetics also had a greater influence on the BMI of the short sleepers, with 70% of their bodyweight controlled by genes, compared to 32% for the long sleepers.
Bodyweight is shaped by many factorsâ€”both genetic and environmentalâ€”that combine to determine how much you weigh. Previous studies have shown that genes can influence weight by controlling many of your bodyâ€™s functions, such as glucose metabolism, energy use, storage of fatty acids, and feeling full. By affecting those genes, sleep can also alter weight.
â€śThe less sleep you get, the more your genes contribute to how much you weigh. The more sleep you get, the less your genes determine how much you weigh,â€ť Dr. Nathaniel Watson, one of the studyâ€™s authors, told USA Today. Is it possible to sleep the pounds off? Not quite. Sleeping more than nine hours a night, though, can reduce the influence of your genes on your weight. That gives more power to environmental factorsâ€”like diet and exerciseâ€”things that you can consciously control. And if youâ€™re not sleeping well, try working out. Youâ€™ll get a good nightâ€™s rest and lose even more weight.
