This is something I’ve heard a lot, and assuming it’s true, what’s the science behind it? Surely holes in masks are the same size no matter whether the germs are heading in or out, but I’m guessing it’s not about the holes and I’m missing something.
Obligatory disclaimer: I’m not an anti-masker, I’m still wearing it in shops for example. This is just me wanting to understand.

The mask stops tiny spit and cough particles from going out of your face. Not entirely, but it helps reduce it by a lot. you are more likely to catch germs through touching stuff with your hands. Unless you rub your face on things in public..
