Red light therapy, also known as photobiomodulation (PBM), is being investigated as a potential treatment for migraines. Research suggests it may work by improving cellular function and reducing inflammation, potentially decreasing migraine frequency and severity when applied to the head. Preliminary studies show positive outcomes with light therapy reducing pain and medication intake for migraine sufferers, and even alleviating TMD-related headaches by targeting specific muscle points. The therapy is considered safe and is becoming more accessible through various devices, though further research is needed to confirm these initial findings and standardize treatment methods.
