Your breath (what you exhale) always contains substantial amounts of moisture (and yes, potentially virions). It does not matter if you speak or not. It does not matter if the environment is cold or not. There is no "simple warm air" out of your lungs.

I agree with mtn_nerd, you must be trolling. Considering your choice of words, you're probably well aware of that.

The breath you see in cold weather is not aerosols but condensed moisture. I don't know how pointing out this trivial fact can be construed as trolling.

Moisture floating out of your mouth is aresolized moisture.

[WithinReason]

Then why do you only see it in cold weather? This is primary school physics...

[jjeaff]

Because in cold weather the aerosolized moisture condenses.

[WithinReason]

That is a completely nonsensical sentence.

There is a large, whiny portion of HN who were so severely injured by the COVID-19 fear porn that they uncritically consumed that they see viruses in their sleep still, two years later. It’s quite sad.
