Poor Sleep Costs Over-50s Nine Months of Career: New Study 2026

Poor sleep can cost over-50s nine months of career, according to a new study from the University of Turku. The research, published in the journal Sleep, reveals that moderate to severe sleep disturbances significantly reduce working life expectancy after age 50. This finding underscores the importance of addressing sleep issues for both employees and employers.

Study Overview: Sleep and Working Life Expectancy

The study analyzed data from the Finnish Public Sector (FPS) study and the Health and Social Support (HeSSup) study, tracking sleeping habits of participants after they turned 50. Researchers categorized nightly sleep length as short (under 7 hours), mid-range (7–8.5 hours), or long (9 hours or more). Sleep disturbances included difficulty falling asleep, difficulty staying asleep, waking up too early, and nonrestorative sleep.

Results showed that participants with moderate sleep disturbances could expect to work nearly five fewer months between ages 50 and 68, while those with severe disturbances lost eight months. Interestingly, short and mid-range sleep lengths were both associated with a working life expectancy of 13 years and two months, but long sleep (9+ hours) reduced that to 12 years and five months.

Gender and Job Type Differences

The longest working life expectancy—almost 14 years—was observed among professional women with no sleep disturbances. In contrast, men in routine jobs with severe sleep disturbances had the shortest, at nearly 12.5 years. This suggests that both gender and occupational status play a role in how sleep impacts career longevity.

These figures highlight that while short sleep is often highlighted as a risk, long sleep also carries a penalty. The study's lead investigator, Dr. Saana Myllyntausta, noted that the lack of difference between short and mid-range sleep was surprising, suggesting that sleep quality may matter more than duration alone.

Key Takeaways for Workers and Employers

• Sleep disturbances can reduce working life by up to 8 months after age 50.
• Long sleep (9+ hours) is associated with a shorter working life than mid-range sleep.
• Professional women with no sleep issues have the longest working life expectancy.
• Employers should consider sleep health programs to retain experienced workers.
• Addressing sleep problems early can extend career longevity.

Practical Tips to Improve Sleep and Protect Your Career

To mitigate the impact of poor sleep, experts recommend maintaining a consistent sleep schedule, creating a restful environment, and limiting caffeine and screen time before bed. For those with chronic sleep issues, consulting a healthcare provider is essential. Simple changes like regular exercise and stress management can also improve sleep quality.
