Sauna of “Ezerkalni”
Since time immemorial people go into sauna for various reasons: religious, hygienic, recreational, social or for health purposes.
Sauna as a health procedure is body’s exposure to heat to make it sweat. Therefore body can sweat out toxins. Heat also loosens tight muscles and relieves muscle pain.
Atmospheric conditions comprise the temperature and relative humidity. Humidity is changeable, from 0 to 100 %. Air temperature in sauna can vary from 30 to 150° C. In this range there are such saunas as:
Dry heat sauna – temperature 90 – 110° C, humidity 5 % – 10 % or temperature 120 – 140° C and humidity 5 % – 10 %.
Moist heat sauna – temperature 75 – 90° C, humidity 20 % – 35 %.
Steam sauna – temperature 45 – 65° C, humidity 40 % – 65 %, temperature 65° C and humidity 65 % or temperature 70° C and humidity 65%.
Steam sauna with 100 % humidity – temperature 40 – 45° C, humidity 100 %. There is a belief that steam saunas (for example – Japan saunas) are less effective to restore energy and vitality.
Body’s thermoregulation system can react differently depending of sauna’s humidity. Dry heat helps moisture to evaporate from the outermost layer of the skin, respiratory tract and lunges, it doesn’t heat up the body as much and the gas exchange in lunges doesn’t change. All in all dry heat eases thermoregulation processes and makes it easier to handle the high temperature.
It’s quite the opposite with moist heat. However there are also benefits of steam sauna. It is great for hygiene and toughening up. Dry heat saunas are recommended for less toughened people, as well as for people recovering from illnesses, older people, athletes to restore energy after a lot of physical exercise or to lose some body weight.
