Overworking Proven Hazardous: New Study Links Long Hours to Health Risks
A comprehensive study spanning four European countries—Finland, Sweden, Denmark, and the UK—has shed new light on the health risks associated with long working hours. By examining data from two population cohorts in Finland and nine cohorts across the other countries, involving over 100,000 participants, researchers identified a link between working 55 hours or more per week and an increased risk of cardiovascular death, infections, diabetes, injuries, and musculoskeletal disorders. Interestingly, no significant correlation was found between long working hours and overall mortality.
Key Takeaways
- Working more than 55 hours a week is associated with a higher risk of early cardiovascular death, infections, diabetes, injuries, and musculoskeletal disorders.
- The study did not find a significant relationship between long working hours and all-cause mortality.
- The research involved over 100,000 participants from Finland, Sweden, Denmark, and the UK, making it one of the most comprehensive studies in this area to date.
- This research was supported by numerous prestigious institutions, including NordForsk and the Medical Research Council.
Analysis
This extensive study underscores the complex relationship between work habits and health. While the lack of a connection to all-cause mortality may suggest that long working hours do not necessarily shorten life span, the significant links to severe health issues, including cardiovascular diseases, highlight the need for workplace policies that encourage balanced work hours. The study’s findings could influence future workplace regulations and worker health guidelines, particularly in countries with a culture of long working hours.
Did You Know?
The concept of a 40-hour workweek was popularized in the early 20th century, largely due to the efforts of labor unions in the United States and other industrialized countries. This study's findings challenge the modern-day extension of the workweek and suggest that adhering to this standard could be beneficial for public health.
