Red light therapy
Emerging evidenceWhy it might help
Photobiomodulation with red and near-infrared light is thought to improve local microcirculation (partly via nitric oxide) and cellular energy metabolism in nerve tissue, which may ease neuropathic pain and support sensation.
What the research shows
A systematic review and additional studies suggest red/near-infrared light therapy may improve neuropathic pain, nerve conduction, and protective sensation in diabetic peripheral neuropathy, though studies are small and quality is limited. It shows promise as an adjunct but is not an established treatment.
