Is it true that one shouldn't take a bath after lunch? If so, does it depend on
- how heavy the lunch is?
- whether one is taking a bath or a shower or bathing in a river?
- how warm or cold the water is?
Often, I tend to be in a situation where I go for lunch first and then for bath. So I was wondering, whether it interferes either with digestion or with anything else.
Two contexts for this question (in response to the suggestion in the comments) :
Note : I am not looking for answers for the contexts below, but rather for the questions above.
I have heard a vague saying somewhere, that after a lunch, maximum blood flow is directed to the intestines and a bath might interfere with the digestion. (Purely anecodatal hearsay). I noticed that we burp a bit during the bath, if you have a bath after lunch.
We were once touring a hilly area. We had food at a roadside joint and soon after jumped into the cold river (yes, very cold). After we were back at our room, two of my friends had a severe stomach upset, and two others quite uncomfortable, although I was fine.
