Some countries are especially known for having bidets: South Korea, Japan, Egypt, Greece, Italy, Spain, France, Portugal, Turkey, Argentina, Brazil, Chile, Uruguay, Venezuela, Lebanon, and India.
A bidet (pronounced "be-day") looks like a toilet but has warm-water jets for personal hygiene after you use the toilet. Bidets are normally situated near the toilet and are especially helpful to: people who are recovering from surgery; people who have physical disabilities; people with dexterity or other problems that limit their range of motion; people who have various medical conditions, such as hemorrhoids, diarrhea, dysentery, difficult bowel movements, or other ailments that involve the rectal or genital areas; people who have developmental disabilities, such as Down's Syndrome, mental retardation, autism, or cerebral palsy; men and women who want better hygiene before or after sexual activities; and women who want more effective feminine hygiene during monthly menstrual periods.
While your first encounter with a bidet can be a little daunting, they are actually very simple (and hygienic) to use. Here are a few easy steps to using a bidet.
