Poor Sleep Linked to Nine Months Lost From Working Life After 50

A University of Turku study found that severely disrupted sleep or sleeping nine-plus hours nightly can cut up to nine months from working life expectancy after age 50. Drawing on two large Finnish cohort datasets, researchers found the sharpest losses among lower socioeconomic groups. Severe disturbances cost eight months; long sleep cost nine. Researchers recommended occupational sleep interventions, noting one in three UK workers chronically lacks sleep.
