Actually our ancestors were very educated about mensuration periods but was later misinterpreted so much with every next generation to end up like this.

Same ancestors were the ones who practiced yoga and meditation.

This is such a shame. Shame on us that we don't try to teach them in a way they understand about periods, importance of keep them in clean space, giving them time for good rest during such pain. If other households aren't clean enough, they should stay away from that room. Also, during periods, women need more nutrients than normal days.

Problem is, these people have never read the book. Instead, follow those idiotic pundits who are self proclaimed educated ones (which they are not since most of the only recite and don't even understand the proper meaning of what they are reciting. Actually, they are the ones who misinterpreted the proper way of taking care of women during periods to such horrible one. )

Here's an extract hindufacts.org:

Angirasa Smriti (Verse 37), for example, advises women to resume their household work only after their monthly periods stop. Similarly, Vashishta Dharmasutra (5.6) says that menstruating women should not indulge in physical exertion, be it household work, or activities like running. During Ambubachi festival in Kamakhya temple in Assam, the temple is closed for three days to give rest to the Goddess, who is believed to be menstruating during that time. Similarly, during the Tulu festival called Keddasa in Karnataka, mother earth is believed to have begun her earthly menstrual cycle and is given a rest for three days. This is also practiced during Raja Parva (menstruation festival) in Odisha, where farmers don’t plough the land and give rest to Goddess earth.
