What is the causality between cold temperatures and getting sick?
In: Biology
As edman007 pointed out; it is due to the proximity of other people, rather than an effect of the temperature on the body. In worse weather, more people use public transport more and spend time in shopping Malls for example. Socialising would also tend to be indoors.
Also, cold weather irritates the mucus membranes, giving us the typical ‘sniffy’ nose when out in the cold.
