On the subject of red light devices, here is my personal experience with one. I had plantar fasciitis with a bone spur for almost a year that did not respond to injection and as a person who walks 3-6 miles a day I was beyond myself not being able to walk. I purchased a red light device and used it 5 days a week, 10 minutes per day with the bottom of my feet pointing toward the device about 6”’from it. Within a week I noticed results and within 2 weeks I was back out walking again with continued improvement using it as stated. Made a believer out me. I have read so many articles that it can help with thyroid, osteoporosis, hair loss, sleep etc so I say why not try it. I personally have not noticed a benefit for sleep or other conditions yet but I keep at it. I use the Red Rush 400 and they had a discount at the time using the discount code Energy Blueprint. Not sure if that is still offered.
