The Sauna Is Universal — But Every Culture Does It Differently

The sauna is one of the oldest wellness practices in the world. From the birch forests of Finland to the bathhouses of Russia, cultures across the globe have developed their own rituals, rules, and traditions around heat bathing. What unites them all: the belief that time in the heat is time well spent.

Here's a look at how different cultures approach the sauna — and what you can borrow for your own practice.

Finland: The Original

Finland is the spiritual home of the sauna. With over 3 million saunas for a population of 5.5 million, it's less a luxury and more a way of life. The Finnish sauna (“sauna” is a Finnish word) is typically a wood-fired room heated to 80–90°C, with low humidity until water is ladled over hot stones — a practice called löyly.

Key elements of the Finnish ritual:

• Löyly: The act of throwing water on the kiuas (sauna stove) to create a burst of steam. The quality of the löyly — its heat, humidity, and feel — is taken seriously.
• Vihta (or vasta): A bundle of fresh birch branches used to gently beat the skin, improving circulation and releasing a pleasant, earthy scent.
• The sauna hat: Worn to protect the head from intense heat, allowing longer, more comfortable sessions. A practical tool, not decoration.
• Cold plunge: After the heat, Finns traditionally cool off in a lake, river, or cold shower before returning for another round.
• Silence and stillness: The Finnish sauna is a place of quiet reflection. Loud conversation is considered poor form.

Russia: The Banya

The Russian banya is the Finnish sauna's more intense cousin. Temperatures can reach 100°C or higher, with high humidity — a combination that demands serious heat tolerance. The banya is a social institution: Russians go with friends and family, and sessions can last hours.

Distinctive banya traditions:

• The pareniye: The art of using a venik (a bundle of birch, oak, or eucalyptus branches) to beat and massage the body. A skilled pareniye practitioner is genuinely respected.
• The felt hat (kolpak): Essential in the banya. The extreme heat makes head protection non-negotiable — a tall felt or wool hat is standard kit.
• Kvass and herbal infusions: Water thrown on the stones is often infused with kvass (a fermented bread drink), honey, or eucalyptus oil for added aroma and therapeutic effect.
• Cold plunge or snow roll: The contrast between extreme heat and cold is central to the banya experience. In winter, rolling in snow is not unusual.

Germany and Austria: The Aufguss

In German-speaking countries, the sauna ritual has evolved into a performance art. The Aufguss (literally “infusion”) involves a trained Aufguss master pouring scented water over the sauna stones and then theatrically waving a towel to distribute the steam evenly around the room.

What makes Aufguss distinctive:

• Essential oils — eucalyptus, mint, citrus, pine — are added to the water for therapeutic and aromatic effect
• The towel-waving technique is a genuine skill, with competitions held across Europe
• Sessions are timed and structured, often lasting 10–15 minutes with multiple rounds
• Textile-free bathing is the norm in German sauna culture — swimwear is typically not permitted

Japan: The Sento and Onsen

Japan's heat bathing tradition centres on water rather than dry heat. The sento (public bathhouse) and onsen (natural hot spring) are deeply embedded in Japanese culture, with their own strict etiquette.

• Thorough washing before entering the communal bath is mandatory — the water is for soaking, not cleaning
• Tattoos are traditionally prohibited in many establishments
• Silence and calm are expected; the onsen is a place of restoration, not socialising
• Dry sauna rooms (sauna in Japanese, borrowed directly from Finnish) are increasingly common in modern sento facilities

What Every Ritual Has in Common

Across cultures, the core elements of a meaningful heat bathing ritual are consistent:

• Heat: Sufficient temperature to induce a genuine sweat
• Contrast: Cold exposure between rounds to amplify the physiological benefits
• Repetition: Multiple rounds rather than a single session
• Intention: Treating the sauna as a ritual, not just a warm room
• Protection: Caring for the body — including the head — during intense heat exposure. A dense wool hat is the one piece of kit every tradition agrees on.

Wherever you sauna, the fundamentals hold. Start with the right kit, respect the heat, and take your time.
