The inaugural World Toilet Summit on 19 November, 2001, was the first global meet of its kind.

The day recognises the importance of sanitation crisis around the globe. It became an official United Nations Day on 24 July, 2013.

On World Toilet Day 2015, here are some of the weirdest toilet facts that will surely blow your mind:

  1. More people in the world own mobile phones than a private toilet.
  2. The average person visits the toilet 2,500 times a year i.e., about six-eight times a day. It means a person spends about three years of his life in the toilet.
  3. The first film that showed a toilet flushing was "Psycho." Due to this particular scene, a lot of complaints regarding indecency were made against the movie.
  4. The first toilet air-fresheners were pomegranates studded with cloves.
  5. $100,000 was spent on a study to find whether most people put their toilet paper on the holder with the flap in front or behind. In the end, it was found that three out of four people put the flap in front.
  6. 90% of medicines taken by people are excreted through urination. Hence, sewer systems often contain heavy doses of drugs. A recent study by the US Environmental Protection Agency has found fish containing trace amounts of oestrogen, cholesterol-lowering drugs, pain relievers, antibiotics, caffeine and even anti-depressants.
  7. British public toilets were voted the worst in a 1992 survey, followed by Thailand, Greece and France.
  8. The first ever toilet paper was created in 1391 AD, when Chinese emperors first felt the need to clean themselves after finishing up with the loo.
  9. Some synonyms of the loo used across the world are: Powder room, lavatory, outhouse, ladies, convenience, washroom, men's room, bathroom, dunny, bog, khazi, gents, garderobe, necessary, women's room, restroom, potty, privy, the smallest room, cloakroom, latrine, place of easement, water closet (WC), john, can, little girls' room, little boys' room, throne room, facilities, House of Honour (by the ancient Israelites) and the House of the Morning (by the ancient Egyptians).
