Frost sauna, also known as cold chamber or cryosauna, is a form of therapy in which the body is exposed to extremely low temperatures. This method has gained popularity in recent years as it offers numerous health benefits. Frost saunas are the opposite of the classic Finnish sauna.

As the name suggests, they are cold cabins. Experts call them cold shock rooms because of the icy temperatures. They lure visitors with the promise: beautiful, slim and fit in just 180 seconds. However, there is still no unanimous statement about the extent to which frost saunas have a positive effect on health.

How the frost sauna works

In the frost sauna, temperatures range from minus 125 to minus 147 degrees Celsius. As soon as users enter the frost sauna, they feel nitrogen in gas form on their skin. This reliefs tension and blocks pain. The icy cold sounds daunting to a majority, but the nitrogen is dry. Thus, during the three minutes, the body temperature does not change at all, only the skin cools down.

What are the benefits of the frost sauna?

Doctors recommend alternating showers to stimulate blood circulation and strengthen the immune system. Furthermore, the change between temperatures activates the happiness hormones. According to experts, the same applies to the frost sauna. In addition, it helps to relax, thereby dissolving stress into nitrogen instead of air. The benefits of the frost sauna include:

  • Improved circulation: the cold stimulates blood vessels and promotes blood flow throughout the body. This can lead to better oxygenation of muscles and organs and aid in recovery after physical exertion.
  • Relieve muscle and joint pain: the cold has an anti-inflammatory effect and can relieve pain and inflammation in muscles and joints. This can be especially beneficial for sports injuries, arthritis, or other muscle ailments.
  • Increase energy levels: cold treatments stimulate the metabolism and can lead to an increase in energy levels. Many people report being more vital and alert after a visit to the frost sauna.
  • Strengthening the immune system: the frost sauna can strengthen the immune system and increase resistance to infections. The cold activates certain immune cells that help fight off pathogens.
  • Relaxation and stress relief: the frosty environment in the cold chamber can contribute to deep relaxation and stress relief. The cold stimulates the release of endorphins and other happy hormones that can provide a pleasant sense of well-being.
  • Weight loss: the cold treatment in the frozen sauna can stimulate the metabolism and promote the activity of brown fat cells, which can play a role in fat burning. This can lead to increased calorie consumption and aid in weight loss.

Why do people go to the frost sauna?

There are many reasons why individuals head to a freeze sauna. They are composed of:

  • Asthma
  • Heavy legs
  • Back pain
  • Rheumatism
  • Weight loss

However, to achieve long-term results, visitors should visit this cold cabin regularly. Cold also has a positive effect on inflammations or sports injuries. It accelerates their healing process.

For whom is a visit to a frost sauna suitable?

People who sit a lot or always make the same movements while working can put an end to their suffering. However, it does not work without patience. Regular sessions in the frost barrel are also a necessary condition for success. Patients who are often disturbed by their migraine while working can also visit the cold sauna. This type of cryotherapy is also effective against skin problems. Finally, due to the cold, inflammations recede.

Slimming through cold

People who are unhappy with their weight can also practice sessions in the frost sauna. They burn more than 1,000 calories per visit. In this case, visible results appear after the first visit. Cellulite dimples become flatter. Of course, users who just want to relax also have the opportunity to pay a visit to the Frost Sauna and enjoy this special time out. The relaxation factor is by no means neglected.

Recent research has shown that a strong cold stimulus stimulates the activation of the so-called brown fat cells. A study by ETH Zurich suggests that these special fat cells may play a role in regulating body weight and metabolism.

Brown fat cells contain a higher proportion of mitochondria, which gives them the ability to convert fat into heat. When these fat cells are activated by cold, the body can burn more energy and boost metabolism.

The results of the study support the idea that frost sauna, as a form of cold treatment, can promote brown fat cell activity. This could have a positive effect on weight loss and metabolism.

How often should you go to the frost sauna?

The frequency of visits to the freeze sauna varies from person to person and depends on several factors, including individual health status, personal goals, and the body’s response to the treatment. Beginners are advised to start with a lower frequency to acclimate the body to the extreme temperatures. As a rule, it is recommended to visit the frost sauna once a week.

With regular sauna sessions, the body benefits from the positive effects such as improved blood circulation, relief of muscle and joint pain, higher energy level and strengthening of the immune system. It is advisable to consult a doctor before using the frost sauna regularly, especially if you have certain health conditions or are taking medication. A medical professional can make individual recommendations depending on specific circumstances and needs.

Who is the frost sauna not suitable for?

Although the frost sauna offers many health benefits, it is not suitable for everyone. There are certain groups of people who should refrain from using the frost sauna.

  • People with cardiovascular diseases such as hypertension, coronary artery disease or cardiac arrhythmias should avoid the frost sauna, as the extremely low temperatures can put additional stress on the heart.
  • People with Raynaud’s syndrome, a condition that causes a strong reaction to cold and can lead to circulatory problems in the extremities, should also stay away from the frost sauna.
  • Pregnant women should also exercise caution and consult their physician before using the frost sauna. The effects of extreme temperatures on the fetus have not been adequately researched, so it is advisable to be on the safe side.
  • In addition, people with open wounds, acute inflammation, or skin conditions should avoid the frost sauna, as the low temperatures may exacerbate symptoms.

Please note that this list is not exhaustive and individual circumstances should be considered. If in doubt, it is always advisable to consult a doctor before using the frost sauna to discuss possible risks and make a safe decision.

How long can one stay in a frost sauna?

How long one can stay in the frost sauna depends on various factors, such as individual comfort and cold tolerance. As a rule, it is recommended to limit the time spent in the frost sauna to 2 to 3 minutes. Although it may be tempting to stay longer in the cold, do not overwork your body.

The low temperatures can be a significant strain, especially for untrained individuals or those with certain health conditions. It is recommended to gradually increase the length of stay in the freezing sauna. Beginners should start with shorter sauna sessions and gradually increase the time when they feel comfortable and notice positive reactions from the body.

Also, pay attention to your own body signals. If discomfort, dizziness, or other negative symptoms occur, the sauna session should be discontinued immediately. It is advisable to be accompanied in the frost sauna by a qualified professional. He can make recommendations and adjust the time of stay to individual needs.


Frost sauna offers a variety of health benefits, including improved circulation, relief of muscle and joint pain, higher energy levels, and strengthening of the immune system.

The frequency of frost sauna visits depends on individual factors, but one visit per week is usually recommended.

Certain groups of people such as people with cardiovascular diseases, Raynaud’s syndrome, pregnant women and people with open wounds should be excluded from using the frost sauna.
