To be fair, cold air can contribute to making you sick. I got more misled by being told getting a cold had nothing to do with temperature because it is a virus. It is indeed a virus, but you're more likely to get infected if you get cold.
It's a combination of different factors. Cold weather makes it harder for your airways to defend themselves. There are I believe some cold viruses that are viable for longer or are stronger in cold weather, but since the cold is many different viruses I am not sure how much difference it makes.
True. Influenza viruses don't like heat. You can potentially reduce the amount of active cells substantially by going to the sauna. 60°C is already sufficient to reduce it by 4 orders of magnitude.
It's because your immune system is less efficient at lower temperatures. So being cold doesn't directly make you sick, but it can indirectly contribute to getting you sick.
