A startling trend has emerged in the sleep patterns of American teenagers, with a significant portion reporting extremely short sleep durations. According to a study published in JAMA on March 2nd, 2026, by a researcher from the University of Connecticut, the issue is deeply rooted in societal factors. The concern regarding inadequate sleep in teens has been documented in medical literature since at least the early 1900s, with a notable study in The Lancet in 1905 expressing worry over the sleep hours of boys in British boarding schools, influenced by nighttime lighting. In the 1950s, public attention shifted to evening activities like radio and television, keeping teens awake late. More recently, research has linked insufficient sleep to overstimulation, mental health issues, accidents, and academic struggles. However, the situation has worsened, with teens now experiencing even shorter sleep durations than before. T. Greg Rhee, a psychiatric epidemiologist from the UConn School of Medicine, and his team analyzed Youth Risk Behavior Survey data from 2007 to 2023, revealing that over 50% of teens reported less than 5 hours of sleep per night in the latest survey, the highest number in any previous survey. This extremely short sleep duration is associated with emotional regulation problems, poor academic performance, and increased risks of obesity and diabetes. The trend is concerning, as it affects all subgroups of teens, regardless of risk factors such as depressive thoughts, substance use, or screen time. The percentage of teens getting sufficient sleep (8 or more hours per night) has decreased from over 30% in 2007 to less than 25% in 2023. Rhee and his colleagues emphasize the need for population-level interventions, such as later school start times, to address this issue. They suggest that reforming academic or extracurricular schedules to reduce evening demands could significantly improve sleep health among teens. However, more research is needed to determine the most effective interventions at a population level.
