    Maybe i missed some words in the article, but I don’t see it say when they figured this out. Because it’s been at least a decade since I learned about it in school or from a science magazine at school.

    Have people been going around not knowing about this until now?

    Or is it that only now can they say with certainty this is true?

      It was always my understanding that they detected carbon dioxide we exhaled. This is the first I’ve heard about infrared.

      I don’t remember when I learned about it or how verifiable the source was, but I knew it too for at least a decade. I am a radiant, heavy-breathing, sweaty target. I have outclassed everyone I’ve ever met on the mosquito attraction scale. I’ve used loose longer clothes but thought it was just stopping their bites from reaching my skin. I didn’t think about how it could also be diffusing my thermal appearance since I’d still get bitten on exposed areas like face and hands.

      yeah I thought we (humanity) already knew this and for some time now.
