Suicide link to a lack of sleep

Going to bed early is key to getting enough sleep and helping adolescents feel on top of the world, a study reports. A lack of sleep among youngsters may trigger depression and suicidal thoughts, according to the study by the Columbia University Medical Centre in New York.
“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 the study’s lead author James Gangwisch in the recent issue of Sleep magazine.

“Adequate quality sleep could therefore be a preventative measure against depression and a treatment for depression.” The study followed the nightly habits of 15,659 college and high-school students, and found those who consistently went to bed after midnight had a 24 per cent higher risk of depression than those who turned in before 10pm.
