WASHINGTON, June 7 — A study analyzing data from more than 120,000 U.S. high school students collected between 2007 and 2023 found that a full eight hours of sleep on school nights is becoming increasingly rare.
The research, published in JAMA, adds to a body of evidence that adolescent sleep has become a public-health issue. The trend was seen across demographic groups, not only among vulnerable populations, with teenagers experiencing depression especially affected.
The Findings
Chronic sleep loss in adolescence is associated with higher risks of depression, anxiety, cardiovascular disease and diabetes, as well as poorer academic performance and concentration. The share of teens sleeping less than seven hours rose from about 69 percent to 77 percent, and the proportion sleeping less than five hours climbed from roughly 16 percent to 23 percent, meaning nearly one in four high schoolers now lives with severe sleep deprivation.
Although the study is based on self-reported data, which has limitations, the authors argue the findings are serious enough to justify policy changes, including later school start times that could give teens more rest, improve mental health and boost learning.
Implications and Next Steps
Today’s teenagers are getting far less sleep than their peers did in the 2000s, and researchers warn the trend is a serious and growing health concern. Families with concerns should consult their doctor.
The study’s findings highlight the need for action to address the issue of adolescent sleep deprivation.
A Growing Health Concern
Severe sleep deprivation is a serious issue that can have long-term consequences for teenagers’ health and well-being. The fact that nearly one in four high schoolers now lives with severe sleep deprivation is a stark reminder of the need for action.
As researchers continue to study the issue, it is likely that new insights and potential solutions will emerge. For now, the focus is on raising awareness about the importance of adolescent sleep and the need for policy changes to support better sleep habits.
