📝 Numerous studies support the ability of red light therapy to improve wound healing and reduce scar tissue after surgery, in addition to benefits such as improved muscle recovery, reduction of fine lines and wrinkles, and hair growth. There was one study in Chinese women basketball players (PMID: 23182016) that showed it might support sleep, but more studies are needed to clarify whether it truly is effective in that arena. Personally, I do think it helps me sleep better. I typically use red light therapy 20 minutes before bedtime.
😷 I discuss red light therapy with my patients often for certain musculoskeletal issues. There are several studies which show it also helps with muscle recovery. So far the results I have seen on my own patients, especially with wound healing, have been very good.
✅ Although the data is early and more long-term studies are needed, the results of red light therapy as a whole are promising with little downside. However, always check with your doctor before starting it.
🚨 Red light therapy is used around 15 minutes per day with results seen as early as 3-4 weeks.
