A recent study published in the journal *Pediatrics* has raised serious concerns about the diminishing sleep patterns among American teenagers, revealing that only 22 per cent of older adolescents are achieving the recommended seven hours of sleep per night. This troubling trend, which encompasses data from over 400,000 teenagers across the United States from 1991 to 2023, reflects a broader issue that also resonates within Canada, where 37 per cent of youth aged 12 to 17 are not meeting sleep guidelines set by national health authorities.
The Sleep Deficit in Canadian Youth
The Public Health Agency of Canada advises that teenagers between 14 and 17 should aim for eight to ten hours of sleep each night. However, the reality is stark. Andrew Holmes, a polysomnographic technologist and founder of Sleep Efficiency, pointed out that Canadian teens are grappling with similar pressures as their American counterparts—academic demands, social obligations, and increased reliance on technology, which often results in sleep being sacrificed first.
Holmes emphasised the natural biological shifts that occur during adolescence, noting that teenagers’ circadian rhythms are changing. “They tend to stay up later but still require eight to ten hours for optimal performance,” he remarked. Despite this biological necessity, many are falling short of their sleep needs.
The Impact of Modern Life on Sleep
Jean-Philippe Chaput, a professor at the University of Ottawa and a member of the Healthy Active Living and Obesity Research Group, confirmed that Canadian teens are not getting sufficient rest. He stated that about one-third of adolescents fail to meet the recommended sleep duration, with 70 per cent managing to hit the target. “Adolescents are missing out on vital sleep, which can have long-term repercussions on their health and wellbeing,” he explained.
The factors contributing to this epidemic are multifaceted. “Demanding extracurricular schedules, heavy homework loads, and, notably, excessive smartphone usage,” Holmes noted, are all significant contributors to the decline in sleep quality. The phenomenon of ‘FOMO’—the fear of missing out—exacerbates the issue, prompting many teenagers to remain awake late into the night, scrolling through social media.
The Role of Screen Time and Early Start Times
Chaput acknowledged the role of technology in shaping sleep habits, asserting that social media delays bedtime and leads to later sleep onset. While social platforms serve as essential tools for self-expression and connection during these formative years, the cost is often a good night’s sleep.
Holmes added that early school start times further complicate matters. “With an average start time of 8:30 a.m. in Canada, teenagers must wake up at least by 6:30 a.m. to prepare for school, resulting in a chronic state of sleep deprivation,” he explained. This early rise, combined with the pressures of modern life, leaves little room for adequate rest.
Consequences of Sleep Deprivation
The ramifications of insufficient sleep during adolescence can extend into adulthood. Holmes cautioned that chronic sleep deprivation and inconsistent routines developed in youth can become entrenched patterns. “The teenage years are crucial for establishing long-term habits, and if poor sleep becomes normalised, it often persists into later life,” he said.
A national survey conducted by Leger in March 2026 revealed that 41 per cent of Canadians sleep less than seven hours per night, with 57 per cent reporting difficulty falling asleep and 71 per cent struggling to remain asleep. Even among those who do get sufficient sleep, many still face challenges with sleep quality.
Why it Matters
The ongoing sleep crisis among teenagers underscores a critical need for societal change. As sleep is intricately linked to overall health, academic success, and emotional wellbeing, prioritising adequate rest during formative years is essential. If we continue to undervalue sleep in our culture, we risk perpetuating a cycle of sleep deprivation that could have lasting consequences for future generations. Acknowledging the importance of sleep is not merely an individual concern; it is a public health imperative that demands our immediate attention.
