This reminds me of an argument I had with a friend in October. When the weather got cold, I only wanted to socialize with our small group of friends outside because the open air was safer, but she only wanted to socialize inside because she thought being outside in the cold would make her catch COVID.

Miasma theory rears its ugly head once again: https://en.wikipedia.org/wiki/Miasma_theory#Contagionism_ver...

The night air is dangerous, close those windows before you go to sleep!

Miasma was a perfectly good theory and if anything, is obviously true innately. Bad smelling air from urine, shit, festering corpses and the like, was often laden with viruses, bacteria, and noxious chemical fumes. Sure, plenty of diseases are not airborne but air that smells like shit isn't exactly a boon to be inhaling. There is a non zero chance of getting sick from noxious air.

Yes, it's "obviously true" because of the confounding factors: bad air tends to go hand in hand with dirty water, contaminated food, and infection-carrying insects.

Neither cholera, malaria, typhoid nor plague are airborne, and yet their causes were ascribed to miasmata.

Right but the metabolites produced by the bacteria are harmful in their own right. And let's be clear, there are many airborne contagions like the common cold that haven't been indexed through the centuries. It isn't a good idea to inhale shit air for days on end, just like it isn't a good idea to inhale car fumes for days on end.

Nonsense. The pathogens in urine, shit, and corpses are almost never airborne. And the fumes are only toxic in extremely high concentrations. The chance of getting sick is effectively zero.

Nonsense. The risk is nonzero. Turbid air takes a toll both physically and mentally, and can lead to inflammation and weakening of the body's defenses. Your definition of sick is quite narrow.

No you're just making things up. The link you posted doesn't support your statement.

> Biogenic volatile organic compounds (BVOCs) encompass VOCs emitted by plants, animals, or microorganisms,

> VOCs are produced by animals and microbes

Try to have substantiative things to say instead of spouting off false declarations and inflammatory insults.
