It is my understanding that being cold doesn’t make us sicker (aside from pneumonia) so why is there actually a season where illnesses like the common cold and flu spread faster? Shouldn’t people get sick at the same rate all year?
In: Biology
Viruses do better in colder weather than they do in hot weather, and people traditionally tend to gather around more indoors when it’s cold outside which makes it easier for these things to spread. Colder weather *does* have an effect on your body’s germ-fighting ability, too, especially in your sinuses – your nose tends to get drier in cold, dry climates. The mucus that’s normally there to filter out bad bacteria dries up and you don’t filter things out as effectively.
