Why cant Hindu women pray when they are on their period?

Hindu women are often restricted from participating in religious rituals and ceremonies while menstruating. This is due to the belief that women are considered impure during this time and their presence can defile sacred spaces and rituals. In some Hindu texts, menstruation is seen as a form of pollution that can contaminate others and disrupt the balance of the universe. As a result, women are expected to observe certain restrictions during their period, including avoiding temples, touching religious objects, and participating in rituals. These restrictions are rooted in traditional beliefs and social norms and vary across different regions and communities within Hinduism.
