97 free Hygiene trivia questions with answers — science & nature quiz, new questions added Oct 2026.
42 free Hygiene trivia questions with answers. Hygiene trivia is a lot more entertaining than a health class. These 97 questions cover the inventions and the inventors: soap in ancient Babylon, the Chinese hog-bristle toothbrush, the prisoner who mass-produced toothbrushes in England, the lead toothpaste tube, dental floss, Q-tips, the first deodorant and antiperspirant, roll toilet paper, the safety razor, the flush toilet Queen Elizabeth I tried and the bidet named after a pony. It also covers the medicine: why Ignaz Semmelweis was mocked for telling doctors to wash their hands, John Snow and the Broad Street pump, Joseph Lister's carbolic acid, Florence Nightingale's charts, London's sewers after the Great Stink, fluoridated water, and how many seconds the WHO wants you to scrub. Plus the marketing that changed habits, from Ivory soap that floats to the mouthwash that turned an obscure medical word into a national fear. Every answer is checked against a documented source, so it works for a school health unit, a nurses' quiz night or anyone who likes knowing where everyday things came from.
