Psoriasis and FIR
Relax Sauna Scientific Review
Far-Infrared Sauna Therapy and Psoriasis

Psoriasis is driven by inflammatory immune signaling, stress response dysfunction, and skin barrier disruption. This review explains how far-infrared whole-body hyperthermia may support comfort, circulation, and inflammatory balance as an adjunct to dermatologist-directed care.

Psoriasis involves TNF-α, IL-17, and IL-23 signaling. FIR research in related autoimmune inflammatory conditions shows meaningful symptomatic improvement without worsening disease activity.
Stress & Flares
Stress is a major psoriasis trigger. Whole-body FIR sauna exposure may help shift the body toward parasympathetic balance and reduce sympathetic overactivation.
Skin Circulation
FIR exposure supports vasodilation, dermal microcirculation, and tissue oxygenation, which may help support skin recovery and inflammatory clearance.
What the Research Shows
Direct randomized trials of FIR sauna therapy in psoriasis have not yet been published. However, studies in related Th17/TNF-α autoimmune diseases, including rheumatoid arthritis and ankylosing spondylitis, show FIR sauna therapy was safe, well tolerated, and associated with reduced pain, stiffness, and fatigue.
Why Relax Sauna Matters
Relax Sauna is an FDA-registered far-infrared generator delivering far-infrared energy in the resonant absorption band. FIR works through mild whole-body hyperthermia, water-molecule interaction, vasodilation, sweat response, endocrine signaling, and immune modulation.
Practical Use Guidance
The review suggests 20-minute sessions once or twice daily as a reasonable wellness approach for many users. During active flares, users who feel increased itch may shorten sessions to 10–15 minutes and observe their response.
The Bottom Line
FIR sauna therapy is not a replacement for medical psoriasis treatment. But the evidence reviewed supports its use as a biologically coherent adjunct for inflammatory balance, stress regulation, circulation, and skin-supportive wellness.
