Abstract

Growing research highlights a U-shaped link between women's sleep duration and mortality risk. Both insufficient and excessive sleep are tied to higher death rates, while a consistent 7 to 8 hours of nightly rest is associated with the lowest risk. This trend spans diverse populations, though age, menopause, and race/ethnicity shape risk differences. Underlying drivers include cardiometabolic strain, sleep disorders, inflammation, hormonal imbalance, and cognitive decline. To improve outcomes, promoting healthy sleep should be central in women's health care, with targeted interventions and education supporting sustainable, restorative sleep practices.

Research summary

The paper claims that both insufficient and excessive sleep are associated with higher mortality risk in women, with optimal sleep duration linked to lower risk. This research addresses the relationship between sleep and mortality, which is a significant factor in longevity and overall health outcomes.
