The later a teenager or young adult goes to bed during weekdays, the more likely they are to gain weight over time. Researchers analyzed data of 3,342 teens and young adults and found that the later an individual’s bedtime, the more weight they were likely to gain over a five-year period. Lead author Dr. Lauren Asarnow comments, “These results highlight adolescent bedtimes, not just total sleep time, as a potential target for weight management during the transition to adulthood.”
