Sauna therapy induces a mild heat stress (hormesis), activating heat shock proteins (HSPs) that help maintain protein integrity and reduce inflammation. This process mimics some benefits of cardiovascular exercise, improving endothelial function, lowering blood pressure, and significantly reducing the risk of cardiovascular and neurodegenerative diseases.
Verdict
A high-impact, low-risk habit for cardiovascular health and stress resilience.
