Want To Lose Weight? Sleep More

Want To Lose Weight? Sleep More
You may be spending very few hours for sleep, now stop this and try to relax and avoid gaining weight, that's the message from a recently published study. This interesting study shows that women who sleep 5 hours or less are more prone to weight gain compared to women who sleep 7 hours. Researchers presented this study in the American Thoracic Society International conference in May 2006.

The study was interesting because it showed that women who sleep 5 hours or less per day were 32 percent more at risk of developing significant weight gain compared to women who sleep for 7 hours per day. The definition of significant weight gain was a gain in weight amounting to 33 pounds ore more. The results of this study also indicated that women who sleep 5 hours or less have 15 percent higher risk of becoming obese during the 16 year study period, compared to women who get 7 hours of sleep. The group in between, who had only 6 hours of sleep per day, had 12 percent higher chance of developing major weight gain and 6% increased risk of obesity when compared to women who regularly get 7 hours of sleep.

These conclusions are from a large study, comprising of a total of 68,183 middle-aged women, who were part of the Nurses health study. Women who participated in the study were required to state their sleeping habits and asked to report their weights every couple of years of the span 16 years covered by the study. Even at the beginning of the study women who slept 5 hours or less per day on an average had 5.4 extra pounds in their body in comparison to women who had 7 hours of sleep. The principle investigator of this study, Sanjay Patel MD, who an Associate Professor of Medicine at Case Western Reserve University located in Cleveland, Ohio, says that this is the largest study of sleep habits and weight gain. Dr. Patel says that, this is the first study to show that reduced sleeping is associated with increased risk of weight gain over time.

When they found the difference in weight related to sleeping habits, the researchers tried to analyze if differences in dietary habits and physical activity contributed to the risk of weight gain in women who slept less. The findings from the study however suggest that those who are deprived of sleep are actually eating less compared to women who had good seven hours of sleep. Researchers also enquired and analyzed the physical activity patterns of women who participated in the study, but the analysis did not show any statically significant variations in the exercise patterns between women who had less sleep compared to women who had more sleep. The research data showed that the weight gain in women who sleep less is not explained by eating more or decreased exercises. Researchers believe that women who sleep less may be moving around less outside the setting of planned exercise programs and may be burning less calories. Researchers suggest that further research is needed to determine what causes weight gain in women who sleep 5 hours or less.
