Association of healthy sleep patterns with risk of mortality and life expectancy at age of 30 years: a population-based cohort study.

This article investigates the association between combined sleep behaviors and mortality as well as life expectancy in a nationally representative cohort of 172,321 US adults from the National Health Interview Survey (2013–2018) linked to death records through 2019. A healthy sleep score was defined based on five low-risk sleep factors: 7–8 hours of sleep per day, infrequent difficulty falling asleep, infrequent trouble staying asleep, waking feeling rested frequently, and no use of sleep medication. Results showed that individuals with all five low-risk sleep factors had significantly lower risks of all-cause, cardiovascular, and cancer mortality, with an estimated increase in life expectancy at age 30 of 4.7 years for men and 2.4 years for women compared to those with 0–1 low-risk factors. The study concludes that adherence to a healthy sleep pattern is associated with reduced mortality risk and meaningful gains in life expectancy among US adults.
