From chinese believes
Do you wash your hair or eating cold food during period? From what i've been told by my chinese relative, expecially grandma and aunties, they said we female are weak. So dont wash your hair or eat cold food its bad for our body expecially ovary.. If we eat cold food regulary, it will cause problem to our period flows. Wash hair during period, will cause many problem like back pain etc, in future. But do you believe in it?
