Youths in America are sleeping less than ever before. More than 70% of high school students average less than 8 hours of sleep,1 falling short of the 8 to 10 hours that adolescents need for optimal health.2 Insufficient sleep negatively affects learning and development and acutely alters judgment, particularly among youths.3 We estimated associations between sleep duration and personal safety risk-taking behaviors in US high school students.
