What is infrared sauna
A standard infrared sauna is a cabin made of natural wood or other environmentally friendly material. Infrared emitters are mounted in the walls and under the seats. Individual cabins are very popular, where you can learn the delights of the thermal procedure alone, as well as thermal cabinets for up to 5 people.
IR sources for saunas are special ceramic heaters that are powered from the network. Due to the radiated heat, they provide warming of the tissues to a depth of 4 cm. Heat transfer occurs due to electromagnetic waves of the infrared range without using any transmission medium (air, steam). They are absolutely safe, as they represent the natural heat emitted by any heated bodies. Moreover, the length of their waves corresponds to those emitted by the human body (0.76–3 μm).
In contrast to the bath and the usual sauna in its infrared variety, energy is spent on heating the air, only about 20% of the radiation emitted by the heaters. And in the usual bath - up to 80% of thermal energy is spent on the same purpose. And only then the heated air gradually warms up the human body. Moreover, the heating of tissues in a conventional sauna occurs at a depth of just a few millimeters.
