Why North American Teens Are Losing Sleep at Alarming Rates

A growing number of teenagers in North America are struggling to get enough sleep. Recent studies highlight a worrying trend, with many failing to meet recommended sleep durations. Researchers point to several key factors behind this decline. In Canada, about one third of teenagers between 12 and 17 do not meet the eight to ten hours of sleep recommended for their age group. Early school start times, averaging 8:30 a.m., contribute to the problem by cutting into potential rest periods.

Demanding extracurricular schedules, heavy homework loads, and excessive smartphone use also play a role. Social media, in particular, delays bedtime and reduces overall sleep quality. A March 2026 survey in Canada found that 41% of the general population sleeps less than seven hours nightly.

The issue is not limited to Canada. In the US, a study of over 400,000 teenagers from 1991 to 2023 showed a steady drop in sleep across all age groups. Only 22% of older American adolescents now get at least seven hours of sleep per night. Poor sleep habits formed during adolescence often persist into adulthood, shaping long-term priorities around rest. The data reveals a clear pattern of sleep deprivation among teenagers. Early school times, academic pressure, and digital habits are major contributors. Without intervention, these trends could have lasting effects on health and daily functioning.
