Staying up late makes you drowsy during the day and also creates behavioural and emotional problems, a study says. The study doesn’t talk about sleeping day time behaviour. It believes that teenagers have a tendency to stay up late, and hence should be given appropriate to sleep.

“In other words, it’s not how long you sleep that has the biggest impact on self-regulation, but when you sleep in relation to the body’s natural circadian rhythms and how impaired you are by sleepiness,” said lead study author Dr Judith Owens, director of sleep medicine at Boston Children’s Hospital.
The American Academy of Pediatrics (AAP) recommends that teens get 8 to 10 hours of sleep.For many teens who need to be at school early, these results suggest they’re being set up to struggle with academics and their health.One of the reasons they advise schools to not start before 8.30am.

“Their morning wake time should be around 8am to allow them to get both an optimal amount and timing of sleep,” Owens said. “Both insufficient and misaligned sleep has consequences for physical and mental health (increased obesity risk, depression) safety (car accidents, sports injuries) and academics (absenteeism, lower grades).”
“The results of this study suggest that the kind of circadian misalignment and daytime sleepiness associated with early school start times are associated with impaired self-regulation, which in turn may contribute to risk taking behaviours, poor control of emotions and impaired thinking skills,” Owens added.
Researchers analysed data from an online survey of 2,017 students in Fairfax County, Virginia.
