On medium at around 3m distance, if I put it lower it make annoying noises from switching on/off. For me it’s mostly on the legs. At some point I get too hot and I stop. It’s also make me relaxed/tired after a while, maybe from the heat or infrared? I would definitely go out in the sun instead, but this help in the darkest part of winter. I hope it help you.
