Well, #1 I do sleep a whole lot better and it definitely closed up a 2 year old wound on my leg. My very dark colored legs from something going on with my health has improved tremendously; not so dark now but the varicose veins are still there ... but there are too many benefits to stop me now. My very hefty gal friend says each session stops her knee pain. My cousin's husband says it helps with his back pain after a day of work at the auto shop. I use it almost every day. I read in a color therapy book by a doctor that all red light healing should start at the bottom of the feet. So I put a gravity chair/recliner for the 1st part for 10 minutes. Then I do two 20 minute sessions: one standing, facing away from the RLT and then I end it with sitting in front of it with my feet up; my eyes covered.
