In January 2018 I had a serious case of the flu. I have not been that sick since childhood. I realized I kept experiencing feelings of relief while sitting in front of an infrared heater, and had the thought, "I need this infrared stuff in a blanket." I grabbed my phone and Googled "Infrared blanket." Low and behold, such a thing actually existed! I ordered the throw size and it arrived in days. After one night of sleeping with it, I got that "turning the corner" feeling. I was on the road to recovery, and I was sold! I have not had any flu nor COVID since. I purchased the queen size blanket in May 2020, and donated my throw to my 12 year old doggy pal. My old pal has shown a noticable up-swing in his energy since sleeping with the throw. I think he is getting his groove back.
