We were told that we should not sleep when our hair is wet. Is it true? What is the reason? Is there a scientific explanation for this? On my experience, when I just finished taking a bath and I lay down on my bed, the tendency is for me to get sleepy. There were several times that I got slept. I think the effect will be a headache when you wake up. What are your thoughts about this?
