Lack of Sleep and Obesity
Children who get relatively little sleep each night may be at increased risk of becoming overweight by early adolescence, a published study suggests.
Researchers found that among 785 U.S. children followed since birth, the risk of becoming overweight by sixth grade was related to how much sleep the children got in third grade.
The findings support the theory that sleep, through effects on specific hormones and metabolism, may directly affect weight, according to the researchers.
For example, research suggests that a lack of sleep may lower levels of leptin, a hormone that suppresses appetite.
Similar research has shown a correlation with insufficient sleep and obesity in adults.
