Long-Term Heatwave Exposure and Kidney Function Decline in Korean Adults: A Nationwide Cohort Study

Paper C Peer reviewed Observational

Key takeaways

This large study in South Korea checked whether long spells of very hot weather harm the kidneys. Adults with more heatwave exposure over time had a faster drop in their kidney filtering rate (eGFR). Because it is an observational study, it shows a link, not proof that heat causes the decline. It is a reminder that heat stress can affect the kidneys.
