The secret to a great night's sleep

Six hours of sleep to stop obesity

Following a study carried out by Columbia University and the University of North Carolina, teenagers who regularly get less than six hours of sleep a night are 20 per cent more likely to be obese when they get older.

The study, which took data from over 10,000 Americans aged 16 and then again at 21, found that those who got at least eight hours of sleep on average, had gained less weight.

The American Center for Disease Control and Prevention, who were involved in the study, actually recommended that teens should be getting as much as nine to ten hours of sleep a night in order to prevent obesity in later life.

Shakira Suglia, assistant professor of epidemiology at Columbia University, believes that a good night's sleep not only helps teens to stay alert at school but also ensures they develop into healthy adults. She added, "Once you're an obese adult, it is much harder to lose weight and keep it off. And the longer you are obese, the greater your risk for health problems like heart disease, diabetes, and cancer."
