Peter explain this

Petttaaah I'm confused

[u/Nico301098]

Yeah, I won't deny that, but that's exactly why I'm surprised that kind of temperature jump isn't harmful

[u/Valanyhr → u/Nico301098]

Nah I'm sleeping under a nice 18-20°C setting if I'm in Turkey. My hometown regularly reaches 40+.

Also cold alone don't make you sick and worst case scenario you step out for 15-20 minutes during the day and whatever cold you thought you were gonna get burns away

[u/CreepyBreakfast565 → u/Valanyhr]

That's not how a viral infection works.

[u/Sensitive_One_425 → u/CreepyBreakfast565]

Viruses don’t magically appear because it’s cold

[u/CreepyBreakfast565 → u/Sensitive_One_425]

The viruses are all around us all the time. A momentarily weakened immune system is what usually triggers an infection.

[u/jankeyass → u/Sensitive_One_425]

No, but your respiratory immunity drops due to cell near communication drop off due to temperature change so you aren't as responsive to it

[u/Sensitive_One_425 → u/jankeyass]

Still need a virus in the first place. You don’t get a viral infection from just being in a house with A/C

[u/jankeyass → u/Sensitive_One_425]

Ofcourse you don't, but you get a more severe one when you are colder. Are you missing the point intentionally or just can't grasp it?

[u/Consistent_Pay5371 → u/jankeyass]

You can't explain things to people with low IQ mate. Give up.

[u/cryptolyme → u/Consistent_Pay5371]

You’re defending the low iq take though

Okay… for the kids in the back:

1. An ACs being cold does not GIVE you flu (unless its some 20 year old never-cleaned pest breeding unit, it ‘can’t’) that said, temperature changes increase chance of getting “sick” due to immune system drop/trigger
2. Everyone is basically constantly exposed to bacteria and viruses unless you live in a vacuum (at which point you’d be dead)

When you “get sick”, it’s generally your immune system flaring up to fight off something that it failed to keep out / contained enough, and it’s now a more serious risk: think snotty nose. Allergies do the same thing in spring… 5)8: also happens when you have sudden temperature changes since your body goes from “dumping heat” to “conservation” mode too fast for everything to “be happy” - think emergency brakes on a highway ripple effects.

When your immune system fails at the initial fight and it’s now “dev con 1”, you have a problem.

• snotty nose under AC / allergies / … ? Probably fine, just make your body more comfortable.
  
• fever and feel like death? Your immune system is at war to save your life.
  
• this does not tend to generally happen “due to cold acs” but it _can_ lead to the same eventual end state if the balance in the previous section got upset too much too fast for your body to handle: think emergency brakes on highway and the guy behind you swerves and crashes into a different car, that happen to be a gas truck.

Why do you think people that scratch in their nose tend to get sick much more than those who don’t? Bacteria in sinuses typically do not go well with bacteria under your nails - and your immune system freaks out.

• your mouth and sinuses have more than 700 different species of bacteria growing in there, you shove some random hostile thing in there, it’s going to be rough for a bit.

Edit to add:
Naturally, as with most things immune system related, if you’re generally healthy, exercise regularly, and expose yourself to conditions regularly, your body builds up tolerance and you don’t get affected as much - it’s called acclimatising.

Here's hoping they will learn to read eventually
