I am looking for any truth to walking on cold floor causes stomach ache.? - stomach ache causes more condition_symptoms

I have recently again from Holland with my husband, who is Dutch. A whole family believes in what I think the health problems are unfounded superstition, as on the cold floor because of stomach pains. I searched but could not find all the sources that speak particularly phenonmenon, and I want to see if others have found that this is true in all cultures.
