What research says about light, circulation and muscle comfort.
What research shows
Reviews have found light therapy reduced muscle soreness and supported muscle performance, and low-level light has been studied for neck and low back discomfort.
Why it works

Relevant wavelengths
850nm near-infrared reaches the deeper muscle. 660nm red works near the surface. Together they give a gentle, even warmth.
