RESEARCH / EVIDENCE BOUNDARIES

Infrared, CRPS & the evidence.

A carefully labeled place for what is known, what is personal, and what is still uncertain. No invented study results or miracle claims.

EVIDENCE LENS / FOUR DISTINCT SOURCES

Don't let the labels disappear.

01 / PERSONAL EXPERIENCE

My reported experience

The original infrared article describes mPulse sessions during my Sunlighten employment and Solo System sessions at home. It reflects how I felt then, not a randomized study or a guarantee for others.

02 / MANUFACTURER MATERIAL

What Sunlighten describes

Catalogs document model names, heating configurations, capacity and marketing. Promotional wellness outcomes should not be treated as independently validated CRPS claims.

03 / EXTERNAL RESEARCH

What the literature supports

Evidence about sauna bathing, heat exposure, photobiomodulation and far-infrared heating may involve different devices, patient groups and interventions. A CRPS-specific conclusion needs research involving CRPS and relevant outcomes.

04 / QUESTIONS OPEN

What we cannot yet conclude

How much of an individual's change was associated with heat, rest, meditation, other therapy or time? Which device and duration were involved? What negative experiences or contraindications might be underrepresented?

NOT THE SAME TECHNOLOGY

Infrared ≠ red light ≠ a clinical outcome.

Far-infrared cabin heat, multi-wavelength sauna systems and red/near-infrared photobiomodulation products differ in emitted energy, body exposure and intended use. A product label alone doesn't establish delivered dose or a particular medical result.

Our evidence library now includes a focused inflammation research explainer with 2025 controlled studies and their limitations. A broader CRPS-specific study-by-study bibliography is still being developed.
