In this study, researchers analyzed data from the Youth Risk Behavior Survey from 2007 until 2015, and report that more than two thirds of teens are getting fewer than eight hours of sleep per night. Adolescents who get fewer than six hours of sleep at night were more than twice as likely to report alcohol and other drug use, nearly twice as likely to be involved in fights and three times as likely to consider or attempt suicide, compared with those who slept for at least eight hours at night.
