National trends in chronic kidney disease prevalence by sleep duration in South Korea, 2007 to 2022: A nationwide cross-sectional study.
Key takeaways
This study looked at 87,246 adults in South Korea from 2007 to 2022. It found that people who slept less than 6 hours or more than 9 hours had a higher chance of having kidney disease. This shows a link between sleep habits and kidney health, but it does not prove that bad sleep causes the disease.
