The Finnish classic bath appeared about 2000 years ago. The institution was intended not only for hygienic procedures, but also for communication with friends, colleagues and relatives. The sauna could unite or quarrel with people forever.

The tent later became a stationary structure, a wooden house. The sauna was drowning “in black” when the smoke was launched inside the steam room. Some Finnish baths are still heated today.

Use only coniferous trees, only their broom part. This ensures the right microclimate and prevents the release of wood resin. Prefer spruce and pine. But recently began to meet alder and linden. All interior decoration of the sauna (benches, buckets, shelves) is made of hardwoods.

Such wood has low thermal conductivity. This helps protect visitors from unpleasant burns. An open stove is used as a stove. The stones are located outside, it evenly heats the room. Humidity at the same time does not exceed admissible limits.

It occurred to Dr. Ishikawa that to enhance the therapeutic effect, you can equip a small room with several emitters. This is how infrared outdoor saunas appeared.

The basic principle of operation of infrared outdoor saunas is the radiation of special heaters (emitters) of thermal (infrared) waves. Infrared radiation is completely safe and natural for humans.
