My mom says that I should not take a bath after a long tiring day at work. that I should rest first for a couple of hours before showering my whole self in water. She said that there is a negative reaction on my body, or that I might go crazy, (dunno why?). What do you think of this? Sometimes its so hot that I want to go straight to the shower and just wash away all the dirt I encountered on the way. Do you think its true? And what are the negative effects?
