How do fragrances in the sauna affect the way I feel?

KLAFS FAQ for well-being

Eucalyptus spruce and pine needles have a soothing effect on your respiratory tract. Citrus oils make you feel more cheerful and active. They also have a calming effect, and can help you concentrate better. Rosemary has an invigorating, stimulating effect; lemon balm relaxes you; and camomile is good for your skin. Use sparingly, as you’ll also be inhaling oil particles. For this reason, you should use only high quality oils.
