Red light therapy
Mixed findingsWhy it might help
Red and near-infrared light (photobiomodulation, studied as low-level laser therapy) is absorbed by cells and may modulate local inflammation and pain signaling in soft tissue around the spine.
What the research shows
Evidence is mixed: one meta-analysis found low-level laser therapy may reduce pain versus placebo in nonspecific chronic low back pain, though not disability, while other reviews and health authorities describe the benefit as limited and dependent on dose. Effects, where seen, tend to be modest and short-term.
