Washington: Sleeping less than 8 hours a night may be lead to weight gain in teens, a new study led by an Indian-origin researcher has found.Furthermore, obesity is linked to short sleep duration in teenage boys, with the fewest hours slept linked to the highest BMI levels, the report said.“Sleep is food for the brain. When teens do not get enough sleep, they fall asleep in class, struggle to concentrate, look and feel stressed, get sick more often, and do not meet their obligations due to tiredness,” said study author Lata Casturi, MA, RPSGT, Baylor College of Medicine Sleep Center in Houston, Texas.“Teens who sleep less than 8 hours may also consume more calories than those who sleep more than 8 hours. Therefore, they have a higher risk for obesity and associated health problems, including high blood pressure, heart disease, and stroke.”Ms. Casturi and colleagues, including coauthor Anita Rao, surveyed 255 teens (108 boys and 147 girls) in high school to obtain self-reported measures of height and weight (used for BMI calculation) and both weekday and weekend quantity of sleep.Among boys, results indicated the average sleep time on weekdays was 6 hours and 32 minutes, and on weekends, the average was 9 hours and 10 minutes.Among girls, the average weekday sleep time was 6 hours and 30 minutes, and the average weekend sleep duration was 9 hours and 22 minutes.
