Radiator variants in the infrared sauna
1. the ultraviolet radiation (UV radiation)
This radiation is produced by the sun. Anyone who exposes himself or herself to this radiation unprotected in excess will get sunburn or increase the risk of developing skin cancer.
2. visible light (VIS radiation)
The human eye covers only a small area of this.
3. the infrared radiation or heat radiation (IR radiation)
This radiation is generated in the sun or in a fire and warms the human skin and is often used in medicine. It is part of the optical radiation and part of the electromagnetic spectrum. Every body you touch is heated.
The different infrared rays are divided as follows
Infrared A: short wave (780 to 1400 nm), temperature approx. 500 to 1 700° Celcius, penetration depth approx. 6 mm
Infrared B: Medium wave (1400 to 3000 nm), temperature approx. 250 to 750° Celcius, penetration depth approx. 2 mm
Infrared C: long wave (over 3000 nm to 1 mm), temperature up to max. 250° Celcius, penetration depth approx. 1 mm
Magnesium oxide, quartz sand or ceramic radiators are called spot radiators. The temperature of these radiators is very high and can cause burns if used incorrectly. Leaning against the cabin wall is not possible with these radiators. A combination of infrared B and infrared C radiation is emitted.
Infrared C surface emitters only reach a maximum temperature of 80° Celcius. The radiation in the infrared cabin is even and not so high, and is therefore perceived as pleasant. You can lean against the cabin wall.
