This study tested whether far-infrared sauna sessions (3 times per week for 3 months) could improve quality of life in people with type II diabetes. Researchers found that participants reported improvements in physical health, general health, stress, and fatigue. The study suggests that saunas might help people with diabetes feel better, and interestingly, more people seemed willing to try saunas compared to other lifestyle changes.
While this study focuses on diabetes, it is relevant to ME/CFS research because it examines far-infrared sauna effects on fatigue and quality of life—core symptoms in ME/CFS. The authors cite chronic fatigue syndrome as a condition in which saunas have shown benefit, suggesting potential cross-disease insights for thermal therapy tolerance and subjective symptom improvement in post-exertional malaise-associated populations.
This study does not prove that far-infrared saunas are effective for ME/CFS, as the cohort was exclusively type II diabetes patients and no ME/CFS-specific outcomes were measured. The lack of a control or sham-treatment group means improvements could reflect placebo effects, natural variation, or concurrent lifestyle changes. The very short post-intervention follow-up (1–3 days) cannot establish whether benefits persist or address relapse risk, particularly concerning in populations with post-exertional malaise.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
