Occupational heat, dehydration and kidney injury
Hot outdoor and manual work with repeated dehydration is associated with acute kidney injury and, in some regions, chronic kidney disease of uncertain cause.
Educational only. Associations do not establish individual risk or diagnosis. Read the original sources and limitations.
Illustrative pathway
Extreme heat → Heat strain & dehydration → Acute kidney injury → Kidney disease
Relationship
Association: Observed together; causation not established.
Evidence and uncertainty
Cross-sectional / ecological; high uncertainty.
Summary
Hot outdoor and manual work with repeated dehydration is associated with acute kidney injury and, in some regions, chronic kidney disease of uncertain cause.
Limitations
The cause of these kidney-disease clusters is unresolved — heat strain, agrochemicals, water quality and heavy workloads co-occur. Job exposure and health surveillance are unevenly recorded.
