American teenagers are getting less sleep than previous generations, according to a new study from the University of Minnesota School of Public Health published in Pediatrics journal.

The research documented a consistent decline in sleep duration across all teenage age categories, with current levels reaching record lows. Only 22 percent of older adolescents reported getting at least seven hours of sleep per night, according to the study findings.

Researchers identified multiple factors contributing to reduced sleep among teenagers. Traditional causes including homework demands, social pressures, and part-time employment continue to impact sleep schedules. However, screen time and social media usage have emerged as additional factors reducing nightly rest.

The study represents the latest research examining sleep patterns among American youth. Sleep experts have previously recommended that teenagers receive between eight and ten hours of sleep per night for optimal health and academic performance.

The University of Minnesota researchers did not immediately provide details about the study's methodology or sample size. The findings add to growing concern among health professionals about sleep deprivation among school-age children and adolescents.
