The Safety and Benefits of Overdosing Red Light Therapy: Cellular Inhibition and Apoptosis

Is overdosing Red Light Therapy safe? How much harm can overdosing red light therapy cause? Should it be avoided at all costs? Or can it be utilized in specific contexts for alternative medical applications with minimal side effects? High doses of Red Light Therapy are reported to cause mitochondrial or cellular inhibition, which is the opposite effect that we typically want from the therapy.  "It has been consistently found that when the dose of PBM is increased a maximum response is reached at some value, and if the dose in increased beyond that maximal value, the response diminishes, disappears and...

2025 State of Full-Body Red Light Therapy Research: Mad Science

2025 State of Full-Body Red Light Therapy Research: Mad Science

What does the peer-reviewed literature have to say about Whole Body LED Red Light Therapy? Not much, actually.  It should be shocking to learn that there are very few published studies specifically on whole body red light therapy. Whenever we find a new article on the topic, it is quite a treat.  On January 30th, 2025 - a new systematic review published looking at the effects of Whole-Body Red Light Therapy on sports exercise performance and recovery. Title below: "A systematic review on whole-body photobiomodulation for exercise performance and recovery" [1] PMID: 39883205 https://pubmed.ncbi.nlm.nih.gov/39883205/ Red and NIR Light Therapy holds great promise...
