Peräruiske

Peräruiske, also known as Finnish sauna, is a traditional Finnish bathing ritual that involves heating the body to high temperatures in a sauna, followed by a cold-water immersion. The term "peräruiske" translates to "back splash" in English, referring to the cold water being poured over the back of the person emerging from the sauna. This practice is an integral part of Finnish culture and is believed to have numerous health benefits.

The sauna is typically a small, wood-heated room with a high temperature, often exceeding 90°C (194°F). The duration of the sauna session can vary, but it is common for people to spend 15 to 30 minutes in the sauna. After the sauna session, a cold-water immersion is performed, usually by pouring cold water over the back. This contrast in temperatures is believed to stimulate the circulatory system, improve blood circulation, and promote relaxation.

Peräruiske is not only a physical practice but also a social activity. It is often done in groups, and the ritual includes a communal aspect where participants take turns in the sauna and the cold-water immersion. This social interaction is an essential part of the Finnish sauna culture.

The health benefits of peräruiske include improved cardiovascular health, enhanced immune function, and stress reduction. The practice is also associated with improved mental well-being and a sense of community. However, it is important to note that peräruiske should be approached with caution, especially for individuals with certain medical conditions, as the extreme temperature changes can be stressful on the body. It is always recommended to consult a healthcare professional before engaging in this practice.
