Cardiovascular & Heart Failure Evidence (Key Clinical Trials)
Effects of sauna bath on heart failure (systematic review & meta-analysis)
https://pmc.ncbi.nlm.nih.gov/articles/PMC6489706/
Key findings:
- Infrared sauna exposure was associated with improved left ventricular ejection fraction (LVEF)
- Reduced B-type natriuretic peptide (BNP), a marker of cardiac stress
- Overall improvement in cardiac function in patients with chronic heart failure
Supports potential relevance for cardiovascular function and circulatory health in clinical settings (short-term outcomes).
Cardiovascular Risk & Vascular Function Evidence
Far-infrared saunas for cardiovascular risk factors (clinical review)
https://pmc.ncbi.nlm.nih.gov/articles/PMC2718593/
Includes:
- Evidence from randomized controlled trials (Level I–II studies)
- Improvements in vascular and cardiovascular parameters
- Reported effects on arrhythmias, blood pressure, and cardiac function
Supports use of far-infrared sauna in clinical research contexts related to cardiovascular risk management and vascular function.
Exercise Recovery & Performance Adaptation
Effects of far-infrared sauna bathing on recovery from training
https://pubmed.ncbi.nlm.nih.gov/26180741/
Findings:
- Improved recovery following endurance and strength training
- Reduced markers of muscle fatigue
- Improved subjective recovery perception
Supports potential role in post-exercise recovery and physical performance adaptation.
