What are Jewish personal hygiene practices?

Answer 1

Other than washing hands more often at meals, hygiene practices vary among Jewish people as they would among any other group. Some shower more often, some are pickier about germs. We're all just people. Jewish scripture encourages cleanliness, just as Christian scripture, and medical advice, advocates.

Answer 2

The same as anyone else; with the addition that Jews are commanded to wash their hands before eating bread (Code of Jewish Law, Orach Chaim 158). This is for ritual religious purposes above and beyond the consideration of cleanliness. Also, the act of bathing is mentioned many times in the Torah.

In the medieval period when other populations may have been less scrupulous about washing and bathing, Jews maintained their ancient practices of spiritual and physical cleanliness and every Jewish town, no matter how small, had its bathhouse. This is one of the reasons why relatively few Jews died during the Black Plague (1347-1350).

The saying that "Cleanliness is next to Godliness" has its parallels in Jewish sources.
