Four sauna types from savusauna to electric, the löyly ritual, eight etiquette rules and the sauna-to-avanto cycle. Plus Lapland's stranger saunas.
Since 2020, Finnish sauna culture has been recognised by UNESCO as an Intangible Cultural Heritage of Humanity. For over two millennia, the sauna has been at the centre of Finnish life, a place for physical cleansing, mental restoration, and community.
The oldest and most traditional form, the savusauna has no chimney. The entire room is heated by burning wood, filling it with smoke before bathing. The resulting heat is extraordinarily soft and enveloping.
A minimalist sauna carved into or built adjacent to a frozen lake. The contrast between the intense heat inside and the frozen world outside creates a uniquely powerful sensory experience.
The quintessential summer sauna experience. A traditional wooden cabin on the lake's edge, where you alternate between the intense heat and the cool clarity of the lake water.
The modern evolution of the sauna tradition, found in urban wellness centres and apartment buildings across Finland. Precise temperature control and immediate availability make it the most widely used form today.
Every Finnish home has a sauna. Lapland keeps the ones that don't fit inside a home.
Ylläs runs what it calls the world's first sauna gondola, a heated cabin that climbs the fell while you throw löyly, the treeline dropping away beneath the window. You ride up sweating and ride down cooled: the contrast bath, done at altitude.
A wood-fired sauna built onto a raft and moored a few metres off a quiet shore. No avanto to find, no snowbank to reach, you open the door and step off the deck straight into the lake. Some you can even pilot slowly across the water, steam trailing behind.
No road reaches it. You arrive on skis, snowshoes or behind a team of huskies to a log sauna by a frozen lake, lit hours earlier by someone who knew you were coming. The nearest light is your own. This is the sauna Finns picture when they close their eyes.
Past Utsjoki, where Finland thins to its last villages, sit the northernmost saunas in the European Union. The avanto is the Teno river; the silence is complete enough to hear the stove tick. In midwinter the sun never clears the horizon, so you bathe by candle and aurora.
has no direct translation in any other language. It describes the steam that rises when water is cast upon the hot stones, but it means far more than steam alone. Etymologically linked to the words for breath and spirit, löyly carries the soul of the sauna tradition.
Throwing löyly is an art. Too much water can cool the stones and create an unpleasantly humid environment; too little, and the heat remains dry and harsh. The skilled bather reads the room, the heat, the mood of fellow bathers, the time, and throws with intention.
In Lapland's wilderness saunas, löyly is sometimes infused with tar essence, birch extract, or Arctic cloudberry, carrying the scents of the northern forest into the steam itself.
The sauna has its own social code, passed down through generations.
Always rinse before entering the sauna: it is a matter of respect for fellow bathers and tradition.
The sauna is a place of calm. Loud conversation, boisterous behaviour, or raising your voice are considered poor form.
The sauna is sacred space. Phones and electronic devices are left at the door, without exception.
Always ask if others want steam before throwing water on the stones, especially if newcomers are present.
The birch whisk (vihta or vasta) is used to gently slap the skin, stimulating circulation. Use it thoughtfully.
Sit at the level that suits your tolerance. The upper benches are hottest (80-100 °C), lower cooler. No judgement.
Public saunas traditionally allow nudity, with separate sessions for men, women, and mixed groups. A towel is always provided.
Drink water before, during (in cool-down periods), and after. The sauna is deeply dehydrating, respect your body.
Here is where the sauna stops being a hot room and turns into something stranger and better. You sit in the löyly until your skin can no longer tell warm from too-warm. Then, and visitors never quite believe this until they have done it, you walk out into the −20 °C night and keep walking: to the snowbank, or to the hole cut in the frozen lake.
