Getting to bed at an earlier time may help protect teens against depression and suicidal thoughts. New research in the journal Sleep finds teens who went to bed past midnight were 24 percent more likely to be depressed and 20 percent more likely to have thought about suicide.
Doctors say lack of sleep may hinder a person's ability to cope with stress. It may also affect judgment, concentration and impulse control.
The study is the first to show that sleep deprivation may cause depression and suicidal thoughts in adolescents.
