Relationship between daytime napping duration and pan-cancer risk: a prospective cohort study based on the China Health and Retirement Longitudinal Study (CHARLS)
Longer daytime napping duration was associated with a lower overall cancer risk. After adjusting for multiple confounders, people who napping over 60 min remained linked to an approximately 40% reduction in cancer risk. Our study found an inverse association between daytime napping duration and cancer risk, but larger sample sizes and objective sleep measurements are still needed for validation.
