Heat energy and viruses are not the same thing. Viruses, and bacteria building up on cloth masks will only act to kill the wearer.

But there is a similarity, in the fact that heat energy building up in my coat, will not save you from hypothermia. Where as ''cold" isn't an actual thing, it is the absence of heat, and heat is something we wish to retain. Unlike viruses and bacteria, which we wish to expel from our lungs.

Sorry, I'm not going to go along with your analogies, physical reality doesn't apply itself to comparatives, and what ifs. Similarly this isn't a meme sub, this sub is for facts. Try finding some to support your argument next time. OK?
