In this paper, 67,615 US high school students were anonymously surveyed using the Youth Risk Behaviour Surveys (YRBS) of the Centre for Disease Control and Prevention (CDC) between 2007 and 2015. They were evaluated for average amount of sleep on a school night, as well as risk taking behaviours. Shorter sleep duration was associated with increased risk-taking behaviour in a dose-dependent manner, the less sleep, the more risk-taking behaviour. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Those who slept less than 6 hours were twice as likely to use drugs such as tobacco, cannabis, and alcohol. They were more likely to be involved in risky sexual behaviour. They were more likely to have been in a physical fight and carry a gun. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Those reporting less than 6 hours of sleep were also more likely to be involved in self-harm. They showed more than three times the likelihood of reporting sadness and hopelessness and contemplating or having attempted suicide as opposed to those who slept 8 hours. 70% of high school students were getting less than 8-10 hours of sleep. This study has implications for addressing poor sleep habits in adolescents as this is a crucial part of development and affects their mental and physical health. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
