Sauna Wellness Black Forest: Finnish, bio & steam bath

Four very different sauna experiences await you in our spacious wellness area: the powerful heat of the Finnish sauna, the gentle climate of the bio sauna and the soothing humidity in our two steam baths. Find out why a sauna session is far more than just relaxation - and why saunas have such a special effect on body and mind.

Why saunas are more than just wellness

Four very different sauna experiences await you in our spacious wellness area: the powerful heat of the Finnish sauna, the gentle climate of the bio-sauna and the soothing humidity in our two steam baths.
A sauna is much more than just relaxation - it is a holistic experience for body, mind and soul. Find out in this guide which type of sauna is right for you, how to sauna properly and why a sauna session at Schluchsee is simply part of your wellness vacation in the Black Forest.

Finnish sauna vs. bio sauna: which is the right choice?

Two sauna highlights await you at our wellness hotel at Schluchsee: the classic Finnish sauna and the gentle bio sauna. Both invite you to relax - but which heat experience suits you best?
The Finnish sauna: intense heat for deep relaxation
The Finnish sauna offers intense heat at around 90 °C and low humidity (10-30%). This traditional form of sauna:

Promotes blood circulation

Supports detoxification

Provides profound relaxation

Strengthens the immune system

Who is it suitable for?

Anyone who appreciates intense heat and already has sauna experience. The Finnish sauna is the perfect end to a hike on the Schluchsee circular trail.

The bio-sauna: gentle warmth for relaxed well-being

The bio-sauna, on the other hand, is milder: At 45-60 °C and pleasant humidity (40-60%), it is perfect for anyone who prefers gentle warmth. Special features of the bio sauna:

 

 

Gentle on the circulation

Aromatherapy

Light shows

Longer dwell time

 

 

Who is it suitable for?

 

Sauna beginners, people with sensitive circulation or anyone looking for a particularly gentle form of heat relaxation. Both types of sauna enhance well-being, but differ in terms of the experience: powerful and hot - or gentle and calming.

Fun fact: There are more saunas in Finland than cars - sauna culture is as much a part of everyday life there as coffee is in the morning here. With only 5.5 million inhabitants, there are over 3 million saunas!

Soothing warmth for the body & respiratory tract

In addition to our Finnish sauna and bio sauna, our two steam baths offer a particularly gentle heat experience. With temperatures between 40 and 50 degrees Celsius and a humidity of almost 100%, the steam bath provides a pleasant, moist heat that is good for the body and respiratory tract.

 

The advantages of the steam bath

 

For the skin:
- The high humidity opens the pores intensively
- Promotes blood circulation and has a positive effect on the complexion
- Ideal for dry or sensitive skin
- Supports natural skin regeneration

 

For the respiratory tract:
- The warm, moist air helps to clear the airways
- Facilitates breathing with a blocked nose
- Beneficial for mild cold symptoms (especially in cold winter months)
- Can have a positive effect on the bronchi and lungs

 

For muscles & relaxation:
- Tension is often noticeably relieved in the gentle warmth
- Joints become more flexible
- Stress reduction through a calming atmosphere

The 5 most important health benefits of saunas

 

1. strengthening the immune system:
- Regular sauna sessions (1-2 times a week) train the blood vessels
- The body becomes more resistant to infections
- Studies show that sauna users are 30-50% less likely to catch a cold
- The alternation between heat and cold simulates an "artificial fever" and activates the immune system

 

2. detoxification & skin cleansing:
- Heavy sweating excretes toxins through the skin
- The body loses approx. 0.5-1 liter of sweat per sauna session
- Harmful substances, heavy metals and metabolic waste are also removed with the sweat
- Tip: Drink plenty of water or herbal tea after the sauna to support detoxification

 

3. stress reduction & mental relaxation:
- The heat lowers the cortisol level (stress hormone)
- At the same time, the release of endorphins (happiness hormones) is promoted
- Result: deep relaxation and a better mood
- Afterwards you can relax in the relaxation area at the Auerhahn Hotel

 

4. improved blood circulation & cardiovascular training:
- The alternation between heat and cold acts like a gentle vascular workout
- Blood vessels dilate (heat) and contract (cold)
- This strengthens the cardiovascular system in the long term
- Important: Check with a doctor beforehand if you have existing cardiovascular disease

 

5. better sleep:
- Many people sleep more deeply and restfully after a sauna session
- Muscle relaxation and stress reduction have been proven to improve sleep quality
- Our tip: Take a sauna in the evening and then enjoy a light dinner in the Auerhahn restaurant - you'll sleep like a baby
