One of the reasons there’s so much confusion around red light therapy is because it’s actually been named so many different things! Cold Laser, LLLT, Photon Therapy, Photobiomodulation, LED Therapy, RLT, Light Medicine, Light Therapy, Phototherapy... are we missing anything? Probably! But they can almost always be used interchangeably. Similarly to other forms of medication, LLLT/ Red Light Therapy / Photobiomodulation has its active ingredients or “medicine” (the irradiation parameters) and a “dose” (the irradiation time). The natural assumption that is frequently made with phototherapy or light medicine is, that if a small dose of red or near-infrared light produces a significant therapeutic effect, then a larger dose should produce an even more beneficial effect. However this assumption is frequently not the case with LED waves.
There are a handful of reasons as to why more light is not always better, why light should be used consciously, and thought of as a natural medicine. It's rather complex but if you'd like to explore the subject more and understand clearly why it is possible to overdo it with light therapy, please read BioPhasic Dose Response in LLLT, PubMed, PMID: 20011653
