A recent analysis published in the journal *Pediatrics* highlights a troubling trend: American teenagers are experiencing unprecedented declines in sleep quality and duration. The study, which examined data from over 400,000 adolescents between 1991 and 2023, indicates that only 22 per cent of older teens now manage to achieve the recommended minimum of seven hours of sleep each night. This alarming trend is echoed in Canada, where a January 2026 study found that 37 per cent of youth aged 12 to 17 fail to meet national sleep guidelines, which advocate for eight to ten hours of rest per night.
The Sleep Crisis Among Adolescents
Experts are increasingly concerned about the impact of insufficient sleep on teenagers’ health and wellbeing. According to Andrew Holmes, a polysomnographic technologist and founder of Sleep Efficiency, the pressures faced by Canadian teens mirror those in the United States. “Academically and socially, Canadian teenagers are under intense stress, and sleep often becomes the first casualty,” he stated in a recent interview.
Holmes highlighted that as adolescents transition into adulthood, their sleep patterns naturally shift. “Teens experience changes in their sleep architecture and circadian rhythms, making it essential for them to still get the recommended eight to ten hours for optimal performance,” he explained.
Jean-Philippe Chaput, a professor at the University of Ottawa, concurs, noting that approximately 30 per cent of Canadian adolescents are not achieving adequate sleep. “Adolescents are often sleeping less than eight hours, which is below the recommended threshold,” he said.
Barriers to Restful Sleep
Several factors contribute to the declining sleep duration among teenagers. Holmes identified demanding extracurricular schedules, increased academic pressures, and excessive smartphone usage as significant hurdles. “Many teenagers are up late scrolling through social media, driven by the fear of missing out on conversations and updates from their peers,” he noted.
Chaput echoed these concerns, stating that screen time plays a substantial role in sleep deprivation. “Social media is crucial for teenagers; it helps them connect with friends and shape their identities. However, it often leads them to delay their bedtimes significantly,” he commented.
The consequences of early school start times further complicate the situation. The average start time for schools in Canada is 8:30 a.m., while it is even earlier at 7:45 a.m. in the United States. “To be ready for school by 8 a.m., teenagers often need to wake up by 6:30 a.m., which makes it challenging to achieve the recommended hours of sleep,” Chaput added.
The Ripple Effects of Sleep Deprivation
The implications of chronic sleep deprivation during adolescence can extend into adulthood, establishing long-lasting patterns. Holmes cautioned, “The teenage years are critical for developing lifelong habits, including sleep routines. If teens normalise inconsistent sleep schedules and late-night screen time, these behaviours may persist unless consciously altered.”
A national survey conducted by Leger in March 2026 revealed that 41 per cent of Canadians are getting less than seven hours of sleep nightly. Strikingly, 57 per cent of respondents reported difficulties falling asleep, while 71 per cent struggled to maintain sleep throughout the night. Even among those who claimed to achieve seven or more hours of rest, nearly 65 per cent reported issues with sleep onset or maintenance.
Chaput emphasised the need for society to reassess the value placed on sleep, particularly during the formative teenage years. “We spend about a third of our lives asleep, yet we often undervalue its importance, especially for our youth,” he stated.
Why it Matters
The rising prevalence of sleep deprivation among teenagers poses significant risks to their physical and mental health, academic performance, and overall quality of life. As society grapples with the implications of this crisis, it becomes increasingly vital to prioritise sleep as a fundamental aspect of health and wellbeing. By fostering an environment that values adequate rest, we can help our youth navigate the pressures of adolescence while ensuring they are equipped for a healthier future.
