I’m big fan of Red Light and NIR (near infrared light) Therapy. I use it on myself and on my animals. There are currently more than 3000 papers written on red light therapy. This is no gimmick!

Biological reaction to light has been known for a long time. Vitamin D synthesis in our skin caused by sunlight is an example of a photochemical reaction. When our skin is exposed to sunlight the ultraviolet B (UVB) rays convert 7-dehydrocholesterol (we all have this) to Vitamin D3.

Photobiomodulation is now the accepted term and is slowly replacing what is known as LED Light Therapy, Low-Level Light Therapy, Cold Laser Therapy. Many terms that all refer to red light and/or Near-infrared light therapy.

Cold Laser therapy has long been used by veterinarians to treat a variety of conditions.  Recent studies indicate that red LED light therapy is as (if not even more) effective. This is good news for pet owners since these units can be purchased for a fraction of the cost of the cold laser equipment.

I am currently testing several units. If you already use red light therapy at home please join my study. Contact me here.


Int the book Red Light Therapy: Miracle Medicine the author Mark Sloan has compiled a list of health issues red light therapy has been tested on with positive results.
