More benefits of going to bed early: teens

A study in the journal Sleep, http://www.sciencedaily.com, found that adolescents with bedtimes that were set earlier by parents were significantly less likely to suffer from depression and to think about committing suicide, suggesting that earlier bedtimes could have a protective effect by lengthening sleep duration and increasing the likelihood of getting enough sleep.

Data was collected from over 15,000 adolescents in grades 7 through 12 and their parents, through the National Longitudinal Study of Adolescent Health.

Lead author James E. Gangwisch, PhD, assistant professor at Columbia University Medical Center in New York, N.Y., said that the results strengthen the argument that short sleep duration could play a role in the etiology of depression.

"Our results are consistent with the theory that inadequate sleep is a risk factor for depression, working with other risk and protective factors through multiple possible causal pathways to the development of this mood disorder," said Gangwisch. "Adequate quality sleep could therefore be a preventative measure against depression and a treatment for depression."

The authors reported that there are a number of potential mechanisms by which chronic partial sleep deprivation could contribute to depression and suicidal ideation. A lack of sleep may affect the modulation of emotional brain responses to aversive stimuli; produce moodiness that hinders the ability to cope with daily stresses and impairs relationships with peers and adults; and affect judgment, concentration and impulse control.

They also suggested that behavioral interventions that involve educating adolescents and their parents about healthier sleep hygiene practices and helping them modify maladaptive sleep habits could sever as primary preventative measures against depression and suicidal ideation.
