Study links suicide and lack of sleep in teens

Teenagers who thought about or attempted suicide were more likely to have suffered sleep disorders in earlier years, researchers say.

Sixty percent of teens ages 15 to 17 who engaged in suicidal behavior had trouble sleeping at 12 to 14. Among those who only thought about suicide, 47 percent had trouble sleeping in earlier years.

By comparison, only 26 percent of teens with no suicidal thoughts or behavior had trouble sleeping at ages 12 to 14.
