Thermal Suite
1. Have a shower: Wash yourself decently reasons. You don't want body odors in a sauna/steam room. Make sure mostly for hygienic that you dry yourself. Many spa visitors enter the sauna wet, which is not ideal since the moisture evaporating from your skin cools the body.
2. Stay calmly in the sauna: Relax and don't lift your feet over your head (which you could by lying down). Most of the saunas in spas will have 80 to 90 degrees Celsius. One session should last for 15 minutes.
3. After the 15 minutes, open the door and let fresh air in. The temperature will drop, but only temporarily. Close the door and pour water with aromatic oils on the oven or at Ten spa the equipment does it for you. It will evaporate and then condensate on the skin of everybody in the sauna. This generates an extremely high temperature and can be enhanced by waving a towel around your body. This is called "Aufguss" in German. Wait for a few minutes or for however long you can handle the temperature.
4. Shower briefly with cold water to rinse off the sweat. Following this, go outside in winter to rub snow on your arms and chest - this might be a bit hard at first, but will help to decrease your body's core temperature. In summer, jump into a cold water pool or Experiential shower (@Ten spa) or you might have to use a cold shower for that purpose.
5. Drink a lot to compensate the loss of liquids: Isotonic solutions are good for that, or fruit juices that are diluted with mineral water.
6. Rest for at least 30 minutes.
After this, you could repeat the procedure up to three times. However, newbies to the wellness business are advised to start things easy.
