      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.

      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.
