Question

You feel warm after the bath if you stay in bathroom, name the phenomenon involved in this experi-
ence?

Answer 1

Answer:

I have noticed many times that whenever I enter into the bathroom just after someone else bathed the temperature inside it would be high.

Is it that the body heat comes out when we pour a lot of water on our body? I asked many people this question but no one has the answer.

Note (from a comment) that this is in a warm climate where the bathwater is heated in the afternoons by sunlight on the storage tank, but not in the mornings; the heating of the bathroom is observed in either case. It's not a simple question of passing heated water through the bathroom.
