[0003] For example, an infrared sauna with a number of infrared lamps has become well-known in the art. These infrared lamps can expose specific areas of the body to heat radiation. The application of heat can help with muscle relaxation, thereby increasing a person's sense of well-being and achieving a cosmetic effect. The disadvantage of this is that a person's body temperature in the sauna cabin can only be regulated very imprecisely. Temperatures that are too high or too low, in particular, can lead to a person feeling stressed and uncomfortable, meaning the cosmetic effect of the treatment is not optimal.

The device 1 comprises an application cabin 2 with an interior 2a and a plurality of application devices 3. The application devices 3 can be individually controlled by the control unit 4 with an operating unit 5. At least one application device 3 is designed as an ion device 6 for supplying ionized air into the interior 2a. By combining the application devices 3, an achievable cosmetic effect is improved compared to a single use of the application devices 3. The interior 2a of the application cabin 2 can be closed by a door (not shown), so that the effect of the application devices 3 and in particular of the ion device 6 is improved, since the ionized air is kept within the interior 2a of the application cabin and cannot simply be discharged into the environment.

[0038] The operating unit 5 of the control unit 4 is designed as a tablet. The tablet is connected to the control unit 4 via a wireless radio link. This allows the device 1 to be operated from the interior 2a or from outside the application cabin 2.

The axial fans 24 are arranged one above the other in a vertical direction so that the entire upper body of a person can be supplied with ionized air. Furthermore, the individual fan units 24 can also be controlled individually. The ion channel 9 with the rigid wall 25 leads to particularly low flow resistance.Here, the fragrance unit 17 of the application device 3 designed as an aromatherapy device 16 is arranged in the ion channel 9, so that the fragrance is directly distributed through the fan units 24 in the interior 2a of the. The fragrance sample is distributed throughout the application booth. Fragrance samples are provided via replaceable cartridges 17a, which are housed in a removable holder.

[0051] When using the device 1, user data, such as height, weight, and age, are first recorded in the operating unit 5 of the control unit 4. The control unit 4 derives application parameters from the user data. These include the duration of use, the intensity of use of the individual application devices, and the like. The ion concentration of the ionization device 6 is also adjustable. Subsequently, the individual cosmetic applications are coordinated by the individual application devices 3, and in particular their scheduling, and an application plan is created. The individual application devices 3 are then controlled depending on the application plan. Overall, this allows for an improved cosmetic effect to be achieved.

[0052] Regarding the term ionized air: Due to electrosmog in our environment, the concentration of negatively charged ions (anions) in our ambient air (breathing air) is steadily decreasing, and the production of positively charged ions (cations) in our ambient air (breathing air) is particularly steadily increasing, for example through radio masts, smartphones, Wi-Fi, etc.

[0053] The maximum anion concentration found in nature in the air can, for example, be in the range of 5000 anions per cm 3Ambient air. The control concentration in urban environments can preferably be between 200 (office) and 1200 per cm 3 Ambient air in parks and outdoors. By the sea, in the mountains or in the Forests can have a standard concentration of up to approximately 2500 anions per cm 3 of the ambient air. In densely forested areas with waterfalls, the concentration can even reach up to 5000 anions per cm 3 ambient air.

[0054] For example, by discharging the high voltage of 12KV at the tips of the 3 brushes, the ion device 6 can produce at least 10 million anions per cm 3 Air enriched (immediately near the brushes of the cascades). At a distance of 200 to 300 mm from the ion source (brush), the user receives a constant concentration of at least 1 million anions per cm 3 Air from the ion channel.

[0055] Effect on the human organism: The body can utilize more anions for metabolic processes, cell growth, and regeneration. Anions have a predominantly antibacterial effect and can enhance performance and promote sleep. Anions are particularly essential for the human organism.

[0056] In general, there should always be more anions than cations available to humans in the air. A deficient ratio between negatively charged ions and positively charged ions can often be one of the causes of fatigue, lack of motivation, depression, and insomnia.
