Answer by Connie b. Dellobuono:

Any kind of acute cold exposure will stimulate the vagus nerve (part of the sensory somatic system) which controls gut inflammation .

Cold showers stimulate your autonomic nervous system, improving stress reaction and relieves anxiety and fatigue.

There was a report in the news where children in Russia play in the snow (less clothing) after staying in a sauna and they are the ones who did not catch the cold.

Is there any medical proof of a connection between having cold showers on a daily basis, and being immune to the flu?
