How little are U.S. teens sleeping? In 2021–2023, just 22% of 18- and 19-year-olds regularly got 7+ hours a night. A study spanning more than three decades finds teen sleep has continued to decline. Researchers point to later school start times as one way to help reverse the trend. 🔗 buff.ly/Aqcdi3e
