I think it works.
I've been putting the red light/nir bulb against my  throat and I have hypothyroidism. My body temp, first thing in the morning is around 96 but I have put the red light against my throat about four or five times over two weeks and now first thing, my body temp is over 97 usually around 97.5 And I may improve more. I am also using it on belly fat and I have been slowly losing weight. but I am doing other things so can't promise that is from the red light. But what benefit I have already gotten on  my hypothyroidism is a big improvement already. Good luck if you try it.
