Weight loss leads to better sleep

The Baltimore Sun “Picture of Health” blog reports that according to a study funded by the National Heart, Lung, and Blood Institute, dropping a few pounds “will lead to a good night’s sleep.”

The Time “Healthland” blog reports that the study, presented at the 2012 American Heart Association Scientific Sessions, found that “weight loss, either through diet or a combination of diet and exercise, can lead to better sleep.” After following “77 overweight or obese individuals with type 2 diabetes or pre-diabetes” for six months, half of which “went on a weight-loss diet with exercise training and” and the other half undertook a diet program, researchers “found both groups also equally boosted their sleep quality by about 20%.”

HealthDay reports, “The study authors pointed out that proper sleep quality is important for both physical and mental health. Disruptions in sleep can increase risks for high blood pressure, heart attack, stroke and irregular heartbeat. And the risk for sleep problems is greater for people who are obese, the authors noted.”

These findings were presented at a medical conference. They should be considered preliminary as they have not yet undergone the “peer review” process, in which outside experts scrutinize the data prior to publication in a medical journal.
