I don't know - kinda seems unwise to blast yourself with IR. You may not feel it immediately but I would certainly not rule out any long-ish term healt consequences.
For example: There are, in fact, known risks to near-infrared radiation exposure. Erythema ab igne, for example, is a disorder characterized by a patchy discoloration of the skin and other clinical symptoms. It is caused by prolonged exposure to hearth fires, and it is an occupational hazard of glass blowers and bakers exposed to furnaces and hot ovens (e.g., Tsai and Hamblin 2017). It is not a risk to the general population, however, in that the irradiance is usually many times that of solar near-infrared irradiance.
But seriously: She has 22 IR LEDs. Let's say 50mW each and you have over 1W of illumination in there. If you wore it while outside/at work, it could easily add up to 10 hours a day, 6 days a week. That's really not "nothing", even though the immediate intensity is not comparable to furnace, the overall dosage very well might be...
I have not calculated the power output of those LEDs, I merely pointed out the fact that I don't think healt consequences should be completely overlooked by just saying "meh, it's like red, no worries"...
