Can red light therapy be harmful?

What Are the Risks? Red light therapy is generally considered safe, even though researchers aren't exactly sure how and why it works. And there are no set rules on how much light to use. Too much light may damage skin tissue, but too little might not work as well.
However, a practitioner with little experience or someone who exposes themselves to too much of the treatment may cause tissue and cell damage. Products for use at home may also lead to misuse, causing damage to the skin, burns, or damage to unprotected eyes.

The major contraindications for the use of light therapy are diseases that involve the retina of the eye, such as diabetes, and the use of photosensitizing medications like lithium, melatonin, phenothiazine antipsychotics, and certain antibiotics.
The theory is that red light wavelengths stimulate the production of melatonin. Melatonin is a naturally occurring hormone that helps you sleep. Your brain releases more melatonin as darkness falls and tends to release less when you're exposed to light.
Red light therapy causes vasodilation, which is a temporary widening of the blood vessels, and this can cause some individuals to feel momentarily lightheaded after a treatment session. We recommend getting up slowly from a red light bed to help prevent or lessen this feeling.
