However, a married woman who did not go to the mikvah during her younger years, MUST go to the mikvah once even though her menstrual cycle has ceased. A menstruating woman remains a Niddah until she immerses in a mikvah, and this includes even a post-menopausal woman, who bears her previous niddah status until she goes to the mikvah. Once she immerses in the mikvah, she is no longer niddah, and will likely never be again. Through this immersion, the wife brings holiness into her marriage and draws merit and blessing upon her home and family—including the children she bore in her pre-mikvah era.

Of course, a menopausal woman, even unmarried, may go to the mikvah on the day preceding Yom Kippur, as is customary.
