Exercise Improves Overweight Kids' Sleep
Aerobic exercising during the day may reduce snoring at night for children who are overweight, researchers from the Medical College of Georgia say.
Researchers at the Augusta, Ga., school studied 100 overweight children aged 7 to 11. About 25 percent either snored or had other sleep-related breathing problems, according to surveys completed by the children's parents, WebMd.com said. The researchers divided the children into three groups, two with assigned daily exercise levels and one in which the children continued their usual activities.
When surveyed again, children in the two exercise groups shows a greater drop in snoring and sleep-related breathing problems than children not assigned to exercise. Both exercise groups showed a similar drop in snoring, researchers said.
Children who exercised a minimum of 40 minutes a day also showed the biggest overall improvement in sleep-related breathing problems, researchers said.
The study "adds to the knowledge base about the benefits of physical activity on overweight children's health, even when weight loss does not occur," the researchers said in an article published in Obesity's November edition.
