History of cold

Humanity has been entering cold water for thousands of years.

1. Sauna and cold immersion

   Finland

   Centuries-old, continuous

   The sauna is a domestic and social institution, historically used for bathing, birth and healing.

   Heat in the sauna is followed by immersion in a lake, the sea, or a hole cut through winter ice (avanto).

2. Misogi

   Japan

   Ancient, ongoing

   A Shinto purification practice with religious meaning; not a fitness activity.

   Ritual washing under a waterfall or in cold water, often accompanied by prayer and preparation.

3. Banya

   Russia and Eastern Europe

   Centuries-old

   A communal steam bath at the centre of village and city social life.

   Intense steam and birch venik alternated with cold plunges, snow or cold water pours.

4. Winter bathing clubs

   Nordic countries

   19th century onward

   Organised clubs made year-round sea bathing a civic, sociable ritual.

   Short sea dips through winter, often paired with sauna and community.

5. European hydrotherapy

   Central Europe

   19th century

   The 'water cure' movement built spa towns around therapeutic cold water application.

   Cold wraps, pours, treading and immersion prescribed as structured regimens.

6. Open-water swimming

   Global

   19th century onward

   From Victorian sea bathing to modern cold-water swimming communities worldwide.

   Sustained swimming in unheated natural water, often in organised groups.

These traditions are distinct, with their own histories and meanings. PLUNGD presents them side by side without treating them as interchangeable.
