The classic Finnish sauna takes place in a cabin with wooden benches. In these rooms temperature is brought up to 80-100% and humidity at 10-30%. This first bath of dry air is followed by an overheated steam bath, obtained by throwing water on red-hot stones. Inside the sauna there are in fact a small brazier with a few stones, a bucket full of water and a ladle. By pouring the water on the stones the room fills up with steam causing the body to sweat. In Northern countries this practice is followed by an ice cold bath while in the Terme sensoriali it is followed by a cold shower. The most evident effect of the high temperatures in the sauna is the diaphoretic one: heat stimulates perspiration and the elimination of toxins. During the session the body loses one litre of liquids in the form of sweat, but this is soon reacquired by drinking in the relaxation and tea area. Through perspiration toxins are eliminated and the organism is totally purified. The increase in the body temperature also affects the muscles which relax and reduce contracture. Moreover heat helps eliminate the toxins which slacken the muscles. Detoxification also concerns the mind: in the general relaxing atmosphere guests can lie back and forget all their worries.
Sauna is not suitable for people with cardiac and pressure problems.
