Anal hygiene[1] refers to practices (anal cleansing)[2] that are performed on the anus to maintain personal hygiene, usually immediately or shortly after defecation. Anal cleansing may also occur while showering or bathing. Post-defecation cleansing is rarely discussed academically,[2] partly due to the social taboo surrounding it. The scientific objective of post-defecation cleansing is to prevent exposure to pathogens.[2]
The process of post-defecation cleansing involves washing the anus and inner part of the buttocks with water. Water-based cleansing typically involves either the use of running water from a handheld vessel and a hand for washing or the use of pressurized water through a jet device, such as a bidet. In either method, subsequent hand sanitization is essential[2] to achieve the ultimate objectives of post-defecation cleansing.
