Noticed, on cool cosmos a person show with hand put into plastic (Black) bag. So anyway of disguising yourself from the thermal image?

If you can reduce the surface to the temperature of the environment, one can fool IR. Unfortunately, this may require bulky insulation and considerable care in not showing the face while still breathing. With less sensitive IR light switches the following circumstances prevent them from working.
1. When the background is the same temperature (in the 90's) as the body skin temperature and the lights don't come on.
2. When a person is heavily dressed for cold weather, then all the heat is held in and the surface of the jacket is close to air temp and the lights don't come on.
In both cases, there is not enough difference between the background and the moving body to trigger the circuitry.

I agree with the silvered mylar. That technology was developed by nasa specifically to do that but for the purpose of conserving heat within an envelope.

I can't state with any certainty, but I think some of that Silvered mylar (like in the big silver baloons) coupled with some insulation would probably work.

Infra-red. The other end of the scale from ultra violet.
