Finnish researcher warns against clock changes impacting sleep patterns in shift workers

A Finnish sleep doctor and researcher, Henri Tuomilehto, has voiced concerns over the impacts of clock changes, stating that they disrupt sleep and hinder the maintenance of healthy sleep patterns. He highlights the particular challenges faced by shift workers, as working during the night or evening adds significant stress and goes against natural physiological cycles. Tuomilehto emphasizes the importance of understanding how one’s profession adds to their biological load and encourages individuals to carefully consider what additional stressors they may introduce into their lives.

In a society driven by a 24/7 culture, Tuomilehto criticizes the trend of round-the-clock work in sectors where it isn’t necessarily needed, noting that many supermarkets in Central Europe do not operate 24 hours a day. He urges employers to familiarize themselves with guidelines and research on managing shift work patterns effectively.

Good sleep and its management are integral to overall health, including maintaining regular schedules, eating nutritious food, and exercising whenever possible. Tuomilehto suggests that if individuals prioritize good sleep as part of their lifestyle, minor disruptions will have less impact. He warns that neglecting sleep can lead to significant issues, especially during periods of change, such as daylight saving time adjustments or shifts in work and leisure schedules.

By cultivating resilience through good sleep habits, Tuomilehto believes individuals can better cope with life’s irregularities without suffering severe consequences.
