Symptoms of hyperthermia include fever, dizziness, lethargy,
sleepiness, and fainting. Side effects of hyperthermia include per-
ception disorders, inability to recognize the need to leave the
room, inability to identify imminent danger, harm to the foetus in
the case of pregnant women, inability to physically leave the
room, unconsciousness.
Alcohol, drugs, and medications increase the risk of hyperthermia.
Do not exceed the maximum recommended time in the sauna.
Leave the sauna cabin if your body responds abnormally to the
heat or if you do not feel well.
Avoid alcohol, drugs, and medications when you are using the
sauna.
