You wake up, your knees ache before your feet hit the floor, and your usual routine of pills and ice barely takes the edge off. You've heard about red light, but you're not sure if it's hype or help.
Red light therapy for arthritis uses specific red and near-infrared wavelengths (typically 630–850 nm) to support cellular repair, lower joint inflammation, and ease pain. Used consistently with the right dose and protocol, it can complement medication, physical therapy, and lifestyle care — without the side effects of long-term NSAIDs.

In this guide, we walk through what's really happening inside your joints, where red light therapy actually fits, the wavelengths and doses that matter, what kind of timeline to expect, and where the evidence is strong — or still thin. We at REDDOT LED build phototherapy devices for clinics, brands, and home users, so we've watched a lot of arthritis programs succeed and fail. We'll share what we've seen.
