I have friends who often mention that their child is sick "because they got caught in the rain" or "because they came home from swimming with wet hair".
Surely you get ill because of a virus or bacteria?
These are well informed, sensible women.
I have expressed my doubts that damp socks can cause a snotty nose, but they say that all they know is that after getting cold and / or wet, their child unfailingly develops a cough / a snotty nose / a sore throat or similar.
I am starting to doubt myself.
