Habitually staying up late may lead to serious health problems and even a shorter lifespan, according to a recent study. The research, conducted over a six-and-a-half-year period, found that those who identify as “night owls” face a 10% higher risk of premature death compared to early risers. This study, which involved nearly half a million participants, highlights the potential dangers of consistently going to bed late and waking up late.
Dr. Malcolm von Schantz, a professor of chronobiology at the University of Surrey and one of the study’s authors, explained, “Night owls trying to live in a morning lark world may have health consequences for their bodies.” The study suggested that the misalignment between a person’s internal body clock and their external environment could lead to stress, poor eating habits, and reduced physical activity, all of which contribute to long-term health risks.
Historical context also supports these findings. The industrial revolution marked a shift in human sleep patterns, with artificial lighting and work schedules disrupting natural circadian rhythms. Today, modern lifestyles often exacerbate this issue, with late-night screen use and demanding work hours further pushing people into nocturnal habits.
Experts recommend gradual adjustments for those looking to shift their sleep patterns. “Start by waking up 15 minutes earlier each day and exposing yourself to natural light in the morning,” suggests Dr. Jamie Zeitzer, a sleep researcher at Stanford University. “Small, consistent changes can help reset your internal clock over time.”
For night owls concerned about their health, the study’s findings serve as a wake-up call. Prioritising sleep hygiene, such as reducing screen time before bed, maintaining a consistent sleep schedule, and creating a restful sleep environment, can make a significant difference. If you’re struggling to adjust, consulting a sleep specialist or GP may provide tailored strategies to improve your sleep habits and overall well-being.
