Summary:A new study found that sleep deprivation is associated with an increased risk of obesity. Sleep deprivation may lead to obesity by increasing the levels of ghrelin and decreasing the levels of leptin.
A new study from the United States has found that sleep deprivation is associated with an increased risk of obesity. The study, which followed 18,000 adults for several years, found that people who slept less than 7 hours per night were more likely to be overweight or obese than those who slept 7 to 9 hours per night.
The study's authors believe that sleep deprivation may lead to obesity by increasing the levels of a hormone called ghrelin, which stimulates appetite. Sleep deprivation may also decrease the levels of leptin, a hormone that suppresses appetite.
