Hot water immersion more than doubles core body temperature rise compared to traditional saunas, potentially boosting vasodilation, cardiac output, and immune activity.

Jul 11, 2025

“Cardiac output increased by 3.7 liters per minute with hot water immersion, roughly 60% more than that observed with the traditional sauna. It was also the only method to provoke a detectable immune response, including a post-heating rise in interleukin-6 levels and an increase in the numbers of natural killer cells and CD8+ T cells 24 to 48 hours later.”

Jun 9, 2017

“One of the reasons I find this study so compelling even though it is associative data and does not establish causality is because the sauna activates heat shock proteins, which have been shown in countless animal studies to play a causal role in preventing Alzheimer's disease and other neurodegenerative diseases.”
