Do not visit sauna on a full or empty stomach.
After showering wipe yourselves dry, because only a dry body will sweat well.
Take a towel with you. Lay on the middle bench for ten minutes. A less desired affect will be achieved if sitting on the lowest bench or on the floor. If you choose the highest bench, time yourselves carefully, since higher temperatures can affect the head particularly. Exaggerating may be dangerous.
Prior to leaving the sauna sit up for a few minutes, otherwise blood flow to your brain will be insufficient. Avoid the top-most bench shortly before leaving the sauna.
Immediately after coming out from the sauna, cool yourself down on the terrace by moving all the time, breathing deeply the fresh air in and out.
