> There are still many taboos around menstruation in India. Women can't visit temples or public places, they're not allowed to cook or touch the water supply - essentially they are considered untouchable.
Note that in earlier times getting water in certain region might mean traveling for miles and then bringing water home, which could be pretty heavy. Same is true for cooking, an Indian joint family could be very big (20/25 members). And cooking for the whole family in open fire is not an easy feat either. So most of household work in a big joint family could be extremely strenuous. Some of these traditions let the woman avoid strenuous work during the mensuration.
Though I am speculating here, some of the tradition indeed could be meant for the well being of the woman. It may not be very relevant in the modern world though.
