Niddah

Niddah names both the Jewish legal category of ritual status a woman enters with the onset of menstrual bleeding and the body of law, running from Leviticus through the Mishnah's dedicated tractate of the same name and the later codes that elaborate it, governing conduct during this period, which suspends physical contact, including affectionate as well as sexual contact, between a married couple from the onset of bleeding through a subsequent count of seven clean days confirmed free of bleeding, considerably longer in total than the menstrual period itself for most women, a duration that is a distinctive and sometimes surprising feature of the practice to those unfamiliar with it. The period closes with immersion in a mikveh, the ritual bath, which halakha treats as the specific act that ends the state of niddah and permits the couple's marital relations to resume, tying this practice directly to mikveh immersion as one of its central applications alongside the other uses of ritual bathing addressed elsewhere in the atlas.

Observance of niddah today is concentrated substantially, though not exclusively, within Orthodox Jewish communities, where the laws are treated as fully binding halakha and taught to brides as part of standard premarital religious education, while non Orthodox movements vary considerably in how far they retain the practice, with some non Orthodox Jews observing forms of it by choice and many not observing it at all as a matter of binding law, reflecting the broader denominational divergence over the ongoing authority of rabbinic legal categories more generally.

Contemporary discussion of niddah among Orthodox women and rabbis themselves is genuinely varied rather than uniform, with some describing the practice, particularly its built in period of physical separation within marriage, as fostering renewed intimacy and anticipation within a committed relationship, and others, including some Orthodox feminist voices, raising more critical questions about how the underlying framework of menstrual impurity is taught and experienced, a live internal conversation within observant communities rather than an externally imposed criticism alone, distinct in character from the harder edged restriction and physical danger documented in practices such as chhaupadi, even though both are sometimes discussed together as instances of the broader cross cultural category of menstrual religious restriction.
