What is a finnish sauna (dry), how to use it and what benefits does it provide?

The first question to be answered is what a Finnish sauna is and how it works. Its construction is simple: a dry sauna consists of a wood-finished cabin designed for one or several people, with very low humidity-typically between 5% and 20%. At the same time, temperatures range from 80 to over 100°C. These conditions differ significantly from those in an infrared or steam sauna. The most important element of a dry sauna is the heater with stones that reach very high temperatures. From time to time, water is poured over the stones; it evaporates immediately and briefly increases the humidity in the cabin, intensifying the sensation of heat.

The essence of a Finnish sauna lies in the unique conditions inside it. Its defining characteristics are exceptionally high temperatures and very low humidity. Temperatures of around 100°C-or slightly lower-are standard. By comparison, a steam sauna typically operates at around 50°C. Another distinguishing feature is the low humidity level, which does not exceed 20% and is often only a few per cent. In other types of saunas, this figure is higher; in a steam sauna, it can reach 100%. What else is worth knowing about a Finnish sauna?

A dry sauna is the hottest type of sauna, with lower temperatures found in all other variants. It is extremely hot, and temperatures can sometimes exceed 100°C. These conditions are ideal for promoting perspiration and eliminating toxins from the body, but they may not be suitable for beginners. Those new to sauna use should start at lower temperatures and gradually increase them. When trying a Finnish sauna for the first time, sessions should last only a few minutes. If you are considering installing a Finnish sauna at home, the temperature can be adjusted to suit individual preferences, for example starting at 70-80°C. What does a dry sauna offer, and why is it worth considering?

Regular use of a Finnish sauna brings numerous benefits for the both body and mind. Sweating helps eliminate toxins, which contributes to improved skin condition. Dry heat also helps reduce tension and stress, making it an excellent way to relax after a long day. In addition, a dry sauna supports the immune system, accelerates metabolism, and stimulates the digestive system. It also improves blood circulation and promotes the efficient functioning of internal organs. To gain the maximum benefit from sauna sessions, it is important to understand how to use a sauna correctly and how long sessions should last.

A garden Finnish sauna, a home sauna and one located in a spa center offer many advantages, but how should a dry sauna be used to achieve the best results? There are several basic rules that should be followed. Before a session, the body should be well hydrated to prevent dehydration or fainting. Moreover, it is recommended to wash and dry the body thoroughly before entering. While in the sauna, the duration of the session should be carefully monitored and not exceeded, as this may negatively affect well-being. After leaving the cabin, the body should be cooled down gradually; depending on preference or availability, a cold shower or a bath with cool water may be used. Another important consideration when using a dry sauna safely is taking breaks between sessions. Before re-entering the sauna, you should wait at least 20 minutes. Additionally, two or three cycles per visit are recommended. How should you dress for a Finnish sauna?

To maximize the benefits, it is recommended to use the sauna without clothing. This is a requirement in many public facilities. In some establishments, swimsuits are permitted, and designated textile and non-textile days may apply. If wearing a swimsuit, avoid synthetic materials, which can irritate the skin when heated. A towel to sit on is essential in a Finnish sauna, as it prevents direct contact between the skin and the bench while maintaining hygiene. You may also wrap yourself in a towel, which is generally more acceptable than wearing swimwear or clothing. Towels made from natural fabrics such as cotton or linen are recommended, as they absorb sweat effectively.

Finnish sauna vs. steam sauna - are towel recommendations different? When deciding between a Finnish and a steam sauna, it is worth noting that the high humidity in a steam sauna often makes the use of a towel impractical. For some individuals, this may feel uncomfortable, so factors such as privacy, temperature, humidity and the possibility of using textiles should be considered.

You already know how a Finnish sauna works, how to use it correctly and how to dress for it. Another important question to address is how long you can safely spend in it to maximize the benefits while ensuring safety. The most important rule is that beginners should start with short sessions lasting only a few minutes. Over time, the duration can be gradually extended. A single session should ideally last between 8 and 12 minutes, while more experienced users may remain in the sauna for 12 to 15 minutes, depending on individual tolerance. However, the total time spent in the sauna should not exceed 20 minutes. Typically, two or three cycles are recommended during one visit, each consisting of a stay in the sauna followed by cooling down and a 20-minute rest period. Moreover, if symptoms such as weakness or dizziness occur during a session, you should leave the sauna immediately.

A sauna is commonly associated with relaxation, regeneration and positive effects on health. However, it is not suitable for everyone. A Finnish sauna has certain contraindications, primarily due to the combination of low humidity and exceptionally high temperatures. In some cases, such conditions may pose a risk to health.

People with cardiovascular diseases, such as hypertension, and those with respiratory disorders should avoid using a dry sauna. It is advisable to consult a doctor before beginning sauna use. The same applies to individuals with hormonal disorders, mental health conditions, eye diseases or epilepsy. A Finnish sauna is also not recommended for pregnant women, during menstruation, or for young children. Older adults should exercise particular caution.

If there are any contraindications to using a dry sauna, it is worth considering an infrared sauna as an alternative. It operates under milder conditions and can be used by a broader group of individuals.

A dry sauna is one of the wellness options that supports both physical health and mental well-being. It is an excellent way to relax after a demanding day or physical exertion. By using it correctly-taking into account session duration, rest periods and possible contraindications-you can safely enhance your well-being without resorting to synthetic preparations.
