The researchers in this study followed 15,000 students in the United States between the age of 12-17. They found the average sleeping period was 8 hours and 53 minutes only.
The researchers said that adolescents should sleep at least nine hours or more every night because its much better for their mental health.
The study was led by Dr James Gangwisch a professor at Columbia University College of Physicians and Surgeons in New York. He found that 71 percent of the study subjects in this age group who slept 5 hours or less were more likely to develop depression symptoms or full depression, and 48 per cent were more likely to think about committing suicide than those who reported getting eight hours of nightly sleep.
“Our results are consistent with the theory that inadequate sleep is a risk factor for depression.” Dr Gangwisch said.
- Sleeping at 10p.m or earlier would give them adequate time to sleep. “great for the mental health”
- Sleeping late make them moody and less able to cope with daily stress.
- Sleeping late make them less social, especially with their peers and friends.
Insomnia and other sleep-related problems could lead to illnesses including psychiatric conditions, attention deficit disorder, post traumatic stress and depression, research suggests.
