Cardiovascular Effects

Far infrared is linked to increased blood flow, improved circulation, lower blood pressure, and heart health. Far infrared is associated with benefits for heart function, circulation, and endothelial function. A Sunlighten study is described as finding a statistically significant blood pressure reduction compared with a generic infrared sauna or placebo-like comparison. The transcript does not provide exact cardiovascular effect sizes or the percentage of users with meaningful blood pressure reduction. The article does not provide numerical details for the cited blood pressure trial. Exact magnitude and durability of far-infrared cardiovascular effects are not provided. The article cites a 2005 randomized controlled trial as showing blood pressure reduction with far-infrared Solo domes. The source says a far infrared study found significant core temperature elevation and links this to cardiovascular conditioning. The cardiovascular mechanism is described as both heat-like and wavelength-specific.
