Generally speaking, the room climate conditions in the sweat cabin of a sauna facility are referred to as the sauna climate. The room climate in the sweat cabin is essentially determined by the temperature, humidity and air circulation. In addition, of course, there are the materials used in the sweat room and the design and performance of the sauna oven. It is initially advisable to take a closer look at the three most important factors: air, humidity and temperature.
Sauna climate: air circulation
The air circulation in the sweat cabin has far-reaching effects on both the humidity and the temperature gradient in the sauna. Therefore, special attention must be paid to the installation of special ventilation and extraction devices in the sauna. Faults in the air circulation result in defects in the heating system and thus have a lasting effect on the well-being in the sweat cabin. Both the ventilation and the air extraction must be located near the floor, if possible opposite each other, whereby the air intake opening should generally be located behind the sauna oven.
Sauna climate: regulating the temperature
The increased temperature is a typical feature of the classic sweat cabin. In general, temperatures of between 40° and 100° are reached here, depending on the type of sauna. Typical for the Finnish sauna, for example, is the temperature gradient from about 100° on the ceiling to 70° on the top bench to 40° near the floor. This temperature gradient is mainly caused by the function of the sauna oven and the air circulation.
Sauna Climate: Topic Air Humidity
In the sweat room of a classic Finnish sauna, the relative humidity is between 2 and 60 percent, with the low value at the ceiling and the high value at floor level. Whenever an infusion is carried out, the relative humidity rises for a short time. To achieve a reasonable relationship between temperature and humidity, good air circulation is necessary.
In the final analysis, the three basic factors air, temperature and humidity, accompanied by other factors, play an important role in the typical room climate in the sauna.
Can the room climate in the sauna be influenced?
Of course the sauna climate can be influenced. This is usually already done during the professional planning and the correct construction of the sweat cabin. If mistakes are made here, this has a lasting effect on the sauna climate. Incorrectly installed devices for the air circulation are just as common mistakes as the wrongly dimensioned electric sauna oven or poor heat insulation. The most important factor for the sauna climate is therefore already to be found in the planning stage.
In addition, the sauna climate can also be changed by the basic settings of the sauna oven and air circulation during operation. However, this is rather unusual, as basic fixed values are provided for comfortable sauna operation. Only the air humidity can be changed at short notice, for example by infusions or sudden airing.
In addition to the three basic factors of air, temperature and humidity, various other factors also affect the current sauna climate. These include the number of people in the sauna and the use of different materials. Here, however, the effects are of secondary importance.
