> Health concerns. It is unclear if an attacker would get his eyes and face skins hurt, under the exposure of such a large amount of infrared in a long period of time. If this is true after confirmation from physicians, attackers may not dare to launch attacks with this method, worrying about their health. As a physician, I don't understand this to be a serious concern. UV light is the opposite side of the viable spectrum from IR This is fascinating. What a great idea.

You can be burned by IR light.

  Unlike UV which can cause skin inflammation later, you will certainly notice that your skin is being burned by IR. Have you ever tried to keep your hand close to burning coals?

    This is true. Heat is given off as IR (more broad spectrum) But also you can not notice when you are burned. Or notice it only after the damage is done. Which happens in places like laser labs (very narrow spectrum).

Intense IR can damage the eye; more specifically, it can lead to cataracts. Prior to learning to arc weld, I always thought the primary danger of looking at the arc without protection was UV exposure. However, it turns out that IR exposure is also problematic.

  more specifically, it can lead to cataracts. Not to downplay it, but cataracts are probably the easiest operational procedure on the human body. At least in the rich world. Most people will have to deal with that at one point in their life. Source: Myself; I got both of my eyes fixed last year. While I can appreciate the horror of your eyes cut up, the actual operation is really minimally invasive. Mind you, I'm not arguing that excessive IR - or UV exposure is generally a good idea.
