CAN I USE THE SAUNA IF I HAVE A COLD?
KLAFS FAQ FOR WELL-BEING
You should only use a sauna when you’re in good health. If you’re suffering from an acute illness (e. g., flu) you should be in bed – not in the sauna. As soon as you’re well enough to get out of bed and no longer feel weak or faint, you can start using the sauna again.
