The sauna bather's advisor

The general order of events when sauna bathing or taking a sauna is as follows:

Before the sauna: Preparation phase

After entering the sauna, select the place that you want, e.g. on the middle or upper bench, and sit completely on the towel that you brought along (spread out).
If there is enough room, first of all lay down; otherwise sit with your legs drawn up slightly.
Add water if necessary, whereby you should be in the pre-sweat phase for 5 - 10 minutes before adding water, enjoy adding the water as a "climax" for approximately 6 - 8 minutes, and then possibly go into a post-sweat phase for 1 - 2 minutes.
Usually, the time spent in the sauna (Finnish sauna) is approximately 10 to 15 minutes as a rule.
You should spend the last 2 minutes sitting upright.
Leave the sauna quietly (please not when the water is added).

Spend approximately 2 minutes in fresh air to fill up with oxygen and to cool the respiratory tract.
Cold water applications: e.g. cold water shower, flood shower, or Kneipp hose and possibly a plunge bath. The cold water applications cause the skin to cool.
Hot footbath: Put your feet into ankle-deep hot water that is approximately 40°C. By the blood vessels expanding, the internal heat can pass to the outside through increased circulation to the skin resulting in the body cooling down.
Possibly take a quiet break.
