The Basics & Etiquette
I have never been to a Finnish sauna. What is the number one rule?
Respect the löyly (the steam). Always ask others before throwing water on the stones. A simple "Löylyä?" is the Finnish way of asking permission. Beyond that, the sauna is a space for equality and peace — leave your ego and your phone outside.

Do I really have to be naked?
In Finland, nudity is the norm because it is the most hygienic and effective way for the skin to breathe. However, outside Finland or in a public spa, a clean linen towel is a perfectly acceptable alternative. Avoid synthetic swimwear, as it can off-gas chemicals in high heat.
How long should I stay inside?
There is no correct timer. A Finn stays until they feel ready. For beginners, this is usually 10–15 minutes. Listen to your heart rate — when it begins to pick up significantly, it is time for a cooling break. Our etiquette guide covers the full rhythm of a proper sauna session.
Health & Safety
Is the sauna safe for everyone?
While the sauna has profound health benefits — cardiovascular health, stress reduction, skin clarity — anyone with heart conditions, low blood pressure, or who is pregnant should consult a doctor first. Never enter a sauna under the influence of alcohol.
How much water should I drink?
Hydration happens before, during, and after. Aim for 500ml of water before entering. During your breaks, sip water or electrolyte-rich drinks. If you feel a headache coming on, you have waited too long to hydrate.
Can I go to the sauna if I have a cold?
If you have a fever, stay home. The sauna puts strain on the body that can worsen a fever. However, for a mild stuffy nose, the steam can help clear the airways — just keep the session short and gentle.
The Finnish Method
What is that bundle of branches I see people using?
That is a vihta (or vasta). It is a bundle of birch twigs used to gently whisk the skin, which improves circulation and releases a natural soap-like substance (saponin) and a fresh forest scent. It is the ultimate natural skin treatment. You can learn more in our sauna accessories guide.
Is the cold plunge mandatory?
Mandatory? No. Essential for the full experience? Yes. The thermal shock of moving from heat to cold causes vasoconstriction, which pumps your circulatory system. If you are not ready for a lake, a cold shower works wonders.
Electric vs. wood-burning: which is better?
A wood-burning sauna is the gold standard for soft löyly and atmosphere. However, modern high-end electric heaters — especially those with large stone capacity — can replicate the experience beautifully for urban environments.
Sauna Rituals & Traditions
What are the different types of Finnish sauna?
The main types are: the everyday electric sauna (most common in apartments), the wood-burning sauna (puusauna, found at cottages), and the revered smoke sauna (savusauna, the ancestral type with no chimney, producing the softest löyly). Each offers a distinct experience.
What is the bridal sauna tradition?
The morsiussauna is a centuries-old Finnish tradition where the bride is bathed and prepared on the eve of her wedding. The ritual involves body scrubbing with natural materials like salt and honey, therapeutic birch whisking, and is a celebration of care and renewal.
Can I use herbs or scents in the sauna?
Yes, but never pour essential oils directly on the stones. Add a few drops to the bucket water, or hang dried herb bundles near the ceiling. Traditional Finnish scents include birch, tar (terva), and pine. Eucalyptus and lavender are popular modern additions.
Professional & Practical
What makes a sauna "authentically Finnish"?
According to Sauna from Finland, an authentic Finnish sauna experience involves proper heat quality from a well-built kiuas, the ability to throw löyly freely, natural materials (wood benches, stone), and the full ritual cycle of heat, cooling, and rest. It is a holistic experience, not just a hot room.
I am a hotel or spa owner. Why should I follow Finnish sauna principles?
Most international spas treat the sauna as a storage room for heat. By following authentic Finnish principles, you transform a facility into a destination ritual. Authentic rituals increase guest satisfaction, encourage longer stays, and allow for premium experience add-ons.
