What is a traditional Finnish sauna?

As the name suggests, a Finnish sauna closely mirrors the traditional sauna from Finland that’s been around for thousands of years. A sauna like this has a kiuas or stove at the heart of it that heats a pile of stones.

Here, stones play a crucial part of the sauna heating mechanism as they retain heat. And when you pour water over them, they produce löyly or soft steam which defines the sauna experience.

Speaking of sauna temperature, you’ll find it in the range of 176–212 °F. This is way higher than the average sauna temperature in the country which is kept between 150°F-195°F on purpose. 

The reason? 
Well, the Finns have evolved to have a much higher heat resistance, thanks to the sauna being a part of both their cultural identity and daily routine. On the other hand, for us saunas are still a new world where we improvise, adapt, and find a tolerable way to get heat therapy. 

That said, a Finnish style sauna still has wooden benches arranged at varying heights with the upper benches being hotter and the lower ones being cooler. Meaning you can choose your preferred temperature zone and customize the experience to your comfort.

What are the different types of Finnish style saunas?

You know the basics of a Finnish sauna now. But what if I told you that these traditional saunas too have different types?

Yes, that’s right. 
In fact, from saunas with ancient Finnish heating methods to modern convenient heating options, you can find them all on the market. 

​Overall, here are the different dry Finnish sauna options you can choose from:

1. Smoke sauna (Savusauna)

This is the oldest and most traditional type of Finnish sauna you can find. And although there are plenty of these in Finland, it’s a rarity in our country. 

A smoke sauna or Savusauna doesn’t have a chimney. Instead, it has wood that burns in a stove for hours, filling the whole room with thick and fragrant smoke. 

Here, you’ll wait for the stones to fully heat, and then put out the fire and air out the smoke.

What’s left behind is this beautifully warm, even, and gentle heat that smells of wood and nature. 

Also, the walls in the sauna turn dark from the smoke, giving it a rustic charm. It’s quiet, slow, grounding, and a truly spiritual experience, especially for the Finns.

​Note: A smoke sauna is different from modern-day wood-burning saunas since there’s no chimney.
​​

2. Wood-burning sauna

A wood-burning sauna is what you might picture when we talk about a Finnish traditional sauna. It uses birch logs or other natural wood to heat a stove full of stones. 

The result: You get that cozy crackling fire sound, the smell of burning wood, and a soft heat that’s truly therapeutic. 

This is super popular in wellness resorts where you’ll find them in the form of lakeside cabin saunas. Also, a lot of sauna enthusiasts who want the “real” sauna experience install one in their homes.
​

3. Electric sauna

If you're in the city or living in a small apartment, the electric sauna is your go-to. And take my word, the experience in this is as good as an old-school Finnish style sauna. 

So what’s the difference?
Well, it’s just that instead of wood burning stoves you’re using a more convenient electric heater. 

The electric stove still heats stones just like the traditional ones, so you still get that authentic löyly when you pour water on them.

A sauna like this is compact and super easy to use. All you’ve got to do is flip a switch, set the timer, and you’re on your way to a relaxing session.

What are the science-backed benefits of a traditional Finnish sauna?

Now that you know what a Finnish traditional sauna is all about, you might be curious about its benefits. And rightly so since the health and wellness benefits of a sauna are the most important reason for people to use it in the first place. 

​So, here are the top benefits of a Finnish sauna backed by scientific research:
​

1. Cardiovascular health

Did you know that regular Finnish sauna use is linked to improved cardiovascular health?

Yes, that’s right. 
There are studies suggesting that frequent traditional sauna sessions lower blood pressure, improve circulation, and reduce the risk of heart-related issues. 

Here, the heat exposure helps dilate your blood vessels, improving blood flow and reducing arterial stiffness. This brings down your blood pressure and reduces the risk of heart disease.

​Plus, as you relax in the sauna, it reduces your stress levels and further improves heart health.
​

2. Respiratory support

The warm and humid ambiance of a traditional Finnish sauna helps open up your nasal passage and ease congestion. And this provides great relief if you’ve been experiencing respiratory issues. 

Here’s how it works: 
As you inhale steam during a sauna session, it helps clear mucus from the airways and makes breathing easier. This is particularly beneficial if you suffer from conditions like asthma or bronchitis.
​

3. Mental health support

You might already be aware that spending time in a traditional sauna has positive effects on mental health. 

But how does it work?

Well, exposure to high heat releases endorphins or feel-good chemicals. And this improves your mood and helps manage stress levels. 

Moreover, research shows regular sauna bathing also improves your sleep quality and cognitive function, which is excellent for mental health in the long-run. ​
​

4. Muscle recovery

Heat from all saunas, and not just Finnish ones, are great for muscle relaxation and pain relief. 

Nevertheless, a dry Finnish sauna is simply better. That’s because the higher temperature range here Increases blood flow and delivers more oxygen to tired muscles.

Also, the warmth helps reduce muscle stiffness and improve flexibility. 

​And if you’re someone who experiences chronic pain, regular sauna sessions can more than just provide relief and improve your overall mobility.

5. Immunity boost and detox

If you use a traditional Finnish steam sauna regularly, it stimulates the production of white blood cells, which is essential for fighting off infections. 

Here, heat exposure mimics a fever-like state and helps release heat-shock proteins which improves your body's immune response. 

​Not to mention, a traditional sauna session also helps to flush out toxins and impurities from your skin and detoxifies naturally.
​

Bonus: Benefits apart, saunas are deep rooted in Finnish culture

In Finland, saunas are deeply woven into the fabric of daily life. In fact, with approximately 3 million saunas in a country of 5 million people, sauna culture is integral to Finnish identity.

Traditionally, saunas used to be a place for significant life events like births, healing, and even death rituals. 

And in the modern-day it has retained its significance as a space for relaxation, reflection, and connection. Nowadays, people enjoy their sessions in silence, fostering a sense of peace and mindfulness. 

The best part: The Finns still practice vihta or vasta where they use birch twigs to gently beat the skin. This is a commonplace in Finland and is believed to stimulate circulation and promote relaxation. ​

5 tips to stay safe in a traditional Finnish sauna?

With traditional sauna benefits that are a win-win for everyone, you might already be planning to visit your nearest Finnish sauna. 

But before you do, here are a few tips on how to use a sauna that’ll keep you safe and help you make the most out of your session: ​
​

1. Stay hydrated

One of the most important things during a Finnish sauna session is to stay properly hydrated.

You see, you’re going to sweat a lot, and that’s part of the experience. But all that moisture leaving your body needs to be replaced, or you risk feeling dizzy, weak, or even getting a headache. 

So, take my advice and drink a big glass of water before your session. Also, sip some water or electrolyte-rich drink between rounds if you're doing multiple cycles, and then hydrate again afterward.

Most importantly. avoid caffeine or sugary stuff as they can dehydrate you and make things bad.    ​
​

2. Limit your time

Saunas are amazing for your health, but more isn’t always better. In fact, staying in too long, especially if you're new to it, can lead to overheating, dehydration, or even fainting. 

Now, 10 to 20 minutes is the sweet spot for most people and generally safe too. But I suggest you don’t extend your session beyond that.

Also, if you’re doing multiple rounds, take breaks in between to cool down and rest. And if you start feeling too hot, lightheaded, or uncomfortable, it’s time to step out.
​

3. Avoid alcohol during sauna

Having a cold beer after the sauna sounds super tempting. 
But drinking inside the sauna? 

That’s a big no-no. 

Alcohol affects your body’s ability to regulate temperature and can increase the risk of dehydration, dizziness, or even fainting. Plus, combining intense heat with booze can put extra strain on your heart. 

So, if you're at a sauna party or gathering, save the drinks for after you're done sweating it out. 

Bonus: Sauna can help you with hangovers, but make sure you’re taking the right precautions since your body might be too dehydrated. ​

4. Check with your doctor (if you’ve pre-existing conditions)

If you have any serious health conditions like heart disease, low or high blood pressure, epilepsy, or if you're on medications, it’s super important to check with your doctor.

While sauna bathing is great for your cardiovascular system, it still puts temporary stress on your body. 

This is especially true for women using saunas while pregnant, especially in their first trimester who should get a green light from their healthcare provider. 
​​

5. Supervise children during their session

Kids can use the sauna, but only with care and supervision. 

You see, although it’s totally normal for children in Finland to join family sauna time, they start slow. 

So, if you’re planning to take your little ones to the sauna, make them sit on the lower benches where it’s cooler and ensure they don’t stay in as long. Also, keep an eye on them at all times and take special care of their hydration.
