This cool study showed light’s benefits can travel in the body. Researchers applied red light, a process known as photobiomodulation or PBM, to the back of the legs of  mice and found that this light helped protect and promote health in the brain. They called this application “remote PBM” because the light was not being directly applied to the area of study. Their conclusion is powerful, “These findings establish remote PBM preconditioning as a viable neuroprotective intervention and provide insights into the mechanisms underlying this phenomenon.” This is why we love the ease and comfort of shining pads of medical grade light on the body daily and feel confident in our experience that this light application benefits the whole body, mind and spirit.  https://www.ncbi.nlm.nih.gov/pubmed/30625333
