Dousing is the practice of making something or someone wet by throwing liquid over them, e.g., by pouring water, generally cold, over oneself. A related practice is ice swimming. Some consider cold water dousing to be a form of asceticism.

Cold water dousing

Cold water dousing is used to "shock" the body into a kind of fever. The body's reaction is similar to the mammalian diving reflex or possibly temperature biofeedback. Several meditative and awareness techniques seem to share similar effects with elevated temperature, such as Tummo. Compare cold water dousing with ice swimming. The effects of dousing are usually more intense and longer-lasting than just a cold shower. Ending a shower with cold water is an old naturopathic tradition. There are those who believe that this fever is helpful in killing harmful bacteria and leaving the hardier beneficial bacteria in the body.

Japan

Poland

Śmigus-dyngus (or Dyngus Day) is a festival held on Easter Monday, traditionally celebrated by boys throwing water over girls.

Russia

Jumping in freezing lakes, ice swimming, is an old Russian tradition that goes hand in hand with going to banya, a sauna-like bath. Some douse with a bucket of cold water. The bucket is filled with water and left out overnight. They then walk with it outside and spill it over themselves. Preferences include being barefoot outside on the earth, and performing dousing at certain times and more frequently when ill. For some, dousing accompanies fasting (absence of all food and water) as an alternate means for the body to obtain water. Some follow cold water dousing with air-drying outside or in wintertime taking a "snow bath" by rubbing handfuls of snow on the body or lying/moving in it.

Thailand

Songkran is a popular festival in April which includes dousing using water. It is also celebrated by the Dai people in Yunnan Province in China, and in Laos, Cambodia and Myanmar during the traditional New Year.
