What is Eucalyptus Oil?
Eucalyptus oil comes from the leaves of the eucalyptus tree, mainly found in Australia, though it grows in other parts of the world too.
The oil is extracted through steam distillation, where heat releases its powerful compounds.
The main component, eucalyptol, gives it a fresh, minty scent and strong therapeutic effects.
There are different types, including Eucalyptus globulus and Eucalyptus radiata, each with unique benefits.
Eucalyptus oil stands out for its ability to clear airways, refresh the mind, and fight bacteria. Its invigorating aroma makes it perfect for sauna use.

Why is Eucalyptus Oil Used in Saunas?
Eucalyptus oil transforms the sauna atmosphere into a refreshing, spa-like retreat. Its crisp scent clears the air, making every breath feel deeper and more satisfying while opening up the airways to ease congestion and improve respiratory health.
In humid steam saunas, eucalyptus oil blends effortlessly with the warm moisture, creating a therapeutic vapor that enhances breathing and promotes relaxation.
In contrast, drier saunas allow its invigorating aroma to linger longer in the air, offering a more sustained sensory experience.
In some Oslo saunas, eucalyptus oil is even infused into snowballs and placed in the heat, slowly releasing its invigorating aroma and enhancing the overall experience.
This simple yet powerful addition deepens relaxation, making the warmth more soothing and the air even more revitalizing.
Many sauna-goers find that incorporating eucalyptus oil into their routine turns an ordinary session into a truly refreshing ritual.
Sauna bathing, a practice with deep roots in Finnish tradition, is gaining popularity worldwide, and research is uncovering its significant health benefits.
According to a comprehensive review of studies, regular sauna sessions can reduce the risk of vascular diseases like high blood pressure and cardiovascular issues, as well as improve respiratory health.
The positive effects are linked to enhanced circulation, cardiovascular function, and immune response, showing that the sauna's environment, much like the use of eucalyptus oil, provides real benefits for overall well-being.
Studies also suggest that frequent sauna bathing, similar to the effects of eucalyptus oil, lowers the risk of respiratory diseases like pneumonia, asthma, and chronic obstructive pulmonary disease.
Those who enjoy multiple sauna sessions each week experience significantly fewer breathing issues, highlighting how heat, steam, and natural elements like eucalyptus work together to support lung health.
Beyond its respiratory benefits, eucalyptus enhances relaxation, reduces stress, and boosts circulation, promoting muscle recovery.
Together, these therapeutic effects make it an essential part of a truly revitalizing sauna experience.
The Science Behind Eucalyptus Oil and Sauna Heat
Eucalyptus oil works effectively in a sauna due to its rich compounds like cineole, which has antibacterial and anti-inflammatory properties.
Heat makes cineole more potent, enhancing deep breathing and relaxation. The steam in a sauna helps disperse eucalyptus oil, creating a therapeutic mist that clears congestion.
Additionally, the warmth allows the skin to absorb eucalyptus oil better, improving circulation and soothing muscles. Unlike some essential oils, eucalyptus retains its potency in high temperatures, maximizing its benefits.
Steam inhalation therapy, much like the steam from a sauna enhanced with eucalyptus, has shown potential in managing respiratory conditions.
According to a review of studies, steam inhalation can be a helpful approach for respiratory health, though more scientific backing is needed to solidify its benefits.
This review explored how steam and heat impact SARS-CoV-2, finding that steam inhalation, especially with herbal additions, could be a valuable adjuvant treatment.
The research highlighted the importance of safety and proper application, emphasizing stream's ability to help clear airways, a key benefit also seen with eucalyptus oil in saunas.
This reinforces the idea that heat combined with therapeutic vapors can significantly aid respiratory health, making eucalyptus oil in a sauna a potent combination.
Which Sauna Types Work Best with Eucalyptus Oil?
Steam Saunas
Eucalyptus oil pairs well with steam saunas. Mix a few drops with water before adding it to the steam dispenser to disperse it evenly.
As the steam rises, the oil enhances relaxation and clears the airways, making it excellent for respiratory health.
Other great essential oils for steam saunas include peppermint, lavender, and tea tree oil.
Traditional Finnish Saunas
In a Finnish sauna, eucalyptus oil enhances the experience with its clean scent. Dilute a few drops in water and ladle the mixture onto the hot sauna stones to prevent damage.
The steam carries the aroma, easing breathing and supporting respiratory health. Never use eucalyptus oil undiluted on sauna rocks, as it evaporates too quickly.
Infrared Saunas
Since infrared saunas don’t produce steam, apply eucalyptus oil differently. Add a few drops to a damp towel or diffuser placed inside the sauna.
The warmth enhances the oil’s soothing properties, promoting relaxation and improving air quality.
Eucalyptus and infrared heat together support detoxification and clear congestion.
Wood-Burning Saunas
Eucalyptus oil works well in a wood-burning sauna. Mix a few drops with water before ladling it onto the hot stones for a steady release of fragrance.
This combination deepens relaxation while supporting lung health. Because wood-burning saunas get hotter, eucalyptus oil may dissipate faster, so apply it carefully and in small amounts.
Too much heat can break down its beneficial properties and create strong vapors that may irritate the lungs.
To keep the experience soothing, ensure good airflow and avoid overloading the sauna with oil.
Electric Saunas
In an electric sauna, never pour eucalyptus oil directly onto the rocks. Instead, dilute it in water and sprinkle it onto the stones using a ladle.
This way, the scent releases gradually, enhancing relaxation and clearing your airways.
Because the oil is mixed with water, only a small amount reaches the heater, turning into steam without leaving residue that could affect the heating elements.
This not only keeps your sauna fresh but also helps maintain your equipment over time.
Portable Steam Saunas
Eucalyptus oil enhances portable steam saunas, making small spaces feel like a spa. Add a couple of drops to the sauna’s water reservoir or a diffuser pad for gradual scent release.
The steam helps distribute the oil, easing congestion and promoting relaxation. Always clean the sauna after use to prevent residue buildup.
How to Use Eucalyptus Oil in a Sauna Safely?
Choose High-Quality Eucalyptus Oil
"During the monsoons, eucalyptus oil proves to be a versatile remedy for various common issues.
From colds, coughs, and flu to dandruff, prickly heat, and pimples, eucalyptus oil offers effective solutions," says Dr. Kochhar, a well-known expert in natural remedies.
One user even shared how applying a few drops under the feet helped prevent frequent colds, while massaging diluted eucalyptus water into the hair effectively addressed dandruff and fungal infections.
This highlights the importance of using high-quality eucalyptus oil, as pure and well-sourced varieties maximize its therapeutic benefits. Look for 100% pure eucalyptus essential oil with no additives.
The botanical name Eucalyptus globulus or Eucalyptus radiata should be listed on the label.
High-quality oils are stored in dark glass bottles to protect them from light, preserving their potency.
Low-quality or synthetic oils not only lack the full therapeutic benefits but can also cause irritation, making the sauna experience less enjoyable.
Be wary of oils with an overly sharp or harsh camphor-like scent or an unusually greasy texture, as these could be signs of adulteration with lower-quality camphoraceous oils or carrier oils.
Pure eucalyptus oil should feel light and crisp, with a clean, refreshing aroma that stays true to its natural form, allowing you to fully enjoy its soothing and revitalizing effects in the sauna.
Dilute the Oil Properly
Dilute eucalyptus oil – Essential oils are highly concentrated, so always mix eucalyptus oil with water before use.
Follow the safe ratio – Use about 3-5 drops per liter of water to avoid overpowering aromas and irritation.
Never apply undiluted oil – Pouring pure oil directly onto sauna stones can cause burning, excessive fumes, and discomfort.
Prevent irritation – Undiluted eucalyptus oil may lead to skin sensitivity, respiratory issues, and an unpleasant sauna experience.
Use the Right Amount
A little eucalyptus oil goes a long way. For an average sauna session, 3-5 drops diluted in water is enough.
In larger saunas or those with more people, you may need a few extra drops to keep the scent balanced and noticeable.
In steam saunas, the oil disperses faster, so you may need to reapply every 10-15 minutes to maintain the aroma.
Application Methods
The most common way to use eucalyptus oil in a sauna is by adding diluted oil to water and pouring it over the stones.
Other methods include placing a small bowl of diluted oil near the heat source or using a sauna diffuser.
A diffuser spreads the scent quickly and fills the space with a strong aroma, while stones release the fragrance gradually, creating a milder but longer-lasting effect.
For an even more natural approach, placing fresh eucalyptus leaves on the stones allows the heat to slowly release their invigorating oils, creating a soothing and earthy infusion.
Diffusers may need occasional cleaning, but stones and fresh leaves require no upkeep, making them simple, eco-friendly options. Avoid applying oil directly to hot surfaces.
Avoid Direct Contact with Sauna Surfaces
Eucalyptus oil can seep into sauna wood and stones, leaving stains or a sticky buildup.
Always mix it with water and apply it indirectly. If oil contacts the wood, wipe it down immediately to prevent residue buildup.
Practice Safe Usage
If you have sensitive skin or respiratory conditions, start with a lower concentration to test your body’s reaction. Inhaling too much eucalyptus oil can cause irritation or dizziness. Ensure the sauna is well-ventilated and store eucalyptus oil in a cool, dark place.
Clean and Maintain Your Sauna
Eucalyptus oil can leave residue, so regular cleaning is necessary. Wipe down sauna surfaces with warm water and a mild cleanser after use.
Vinegar helps remove oil buildup without harming the wood. Clean the sauna weekly to prevent stains or lingering residue.
