Essential Oils
Fragrance is one of the most characteristic elements of modern Aufguss—but “natural” does not automatically mean harmless.
Essential Oils in Sauna examines the composition, application and safety of essential oils and fragrances under the unusual thermal conditions of a sauna cabin. Essential oils contain complex mixtures of volatile compounds, and their behaviour depends on concentration, temperature, oxidation, formulation and method of application.
The section covers essential oils for sauna, Aufguss fragrances, fragrance perception, essential-oil dosing, fragrance safety, irritation, sensitisation, toxicology, storage and professional application.
Different essential oils can have very different chemical profiles. Lavender, citrus oils, eucalyptus, peppermint, conifer oils, cinnamon, clove and other aromatic materials therefore cannot simply be treated as interchangeable “natural fragrances.” Some are comparatively suitable for controlled sauna use, while others require caution or should be excluded from routine professional application.
Oxidation is another important issue. Storage, exposure to air, heat and light can change the chemical composition of essential oils and may increase sensitisation potential. Correct documentation and known composition are therefore more important than marketing descriptions such as “100% natural.”
The articles also examine common practices involving menthol, fragrance concentrates and different methods of introducing aroma into the sauna cabin.
The guiding principle is straightforward:
The sauna comes first. Fragrance comes second.
Fragrance should complement a professionally controlled sauna experience—not dominate it or introduce unnecessary chemical and sensory load.
