It's a taboo no one really talks about in remote villages of Himachal Pradesh -- but could soon end. Women in many remote parts of the mountain state are virtually ex-communicated when they are menstruating. They are forced to sleep outside the house in cattle-like sheds known as menstruation sheds. The reason: A woman is considered unclean when she's bleeding or in a post-natal state. The so-called unclean women during their periods and after childbirth are barred from touching cattle or men and they are even denied access to toilets walking miles from their villages daily to take a bath.
