What is Eucalyptus Oil?
- Eucalyptus oil is made from eucalyptus tree leaves: This oil comes from the leaves of the eucalyptus tree, mostly found in Australia but also in other parts of the world.
- Steam distillation is used to get the oil: The oil is taken out by heating the leaves with steam, which releases the strong natural ingredients.
- The fresh smell comes from a special ingredient called eucalyptol: Eucalyptus oil has a cool, minty scent because of eucalyptol, which also helps with many health benefits.

Why is Eucalyptus Oil Used in Saunas?
- Eucalyptus oil makes the sauna air fresh and easy to breathe: 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.
- Eucalyptus oil works differently in steam and dry saunas: In humid steam saunas, eucalyptus oil mixes with warm moisture to create a healing vapor that helps breathing and relaxation. In dry saunas, its fresh smell stays longer, giving a lasting calming effect.
- Some saunas use eucalyptus in snowballs for slow fragrance release: In certain Oslo saunas, eucalyptus oil is added to snowballs placed in the heat, which slowly releases the fresh aroma and improves the sauna experience.
- Eucalyptus oil helps the sauna feel more relaxing and refreshing: Adding eucalyptus oil makes the sauna’s warmth feel more soothing and the air more revitalizing. Many people find it turns a regular sauna session into a refreshing, calming ritual.
- Sauna use is growing and offers real health benefits: Sauna bathing, popular in Finnish tradition, is now more common worldwide. Studies show it can lower risks of heart and blood vessel problems and improve breathing health.
- The sauna environment and eucalyptus oil improve blood flow and immunity: The benefits come from better blood circulation, heart health, and immune support. Eucalyptus oil adds to these effects by making the sauna air healthier.
- Regular sauna and eucalyptus use helps reduce breathing problems: People who visit the sauna often have fewer lung issues like asthma and pneumonia. Heat, steam, and eucalyptus oil work together to protect and improve lung health.
- Eucalyptus oil helps reduce stress and supports muscle healing: Besides helping breathing, eucalyptus oil also calms the mind, lowers stress, and helps muscles recover, making sauna time even more beneficial.
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 should be mixed with water before use: In a wood-burning sauna, mix a few drops of eucalyptus oil with water and pour it on the hot stones for a gentle release of fragrance.
- Wood-burning saunas get hotter, so use oil sparingly: Because these saunas reach high temperatures, eucalyptus oil evaporates faster, so only add small amounts carefully.
- Too much heat and oil can cause strong vapors: High heat can break down the oil and create strong smells that may bother your lungs .
- Good airflow is important when using eucalyptus oil: Make sure the sauna has fresh air and don’t put too much oil in to keep the experience relaxing and safe.
Electric Saunas
- Always dilute eucalyptus oil before adding it to electric sauna rocks: Never pour eucalyptus oil directly on the rocks; mix it with water first and use a ladle to sprinkle.
- Diluted eucalyptus oil releases a steady, relaxing scent: Mixing the oil with water helps the fragrance spread slowly, making the sauna experience more calming and clearing your airways.
- Using diluted oil protects the electric sauna’s heater and keeps it clean: Because the oil is mixed with water, only a small amount reaches the heater as steam, preventing residue buildup and helping your sauna last longer.
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.

- Pure eucalyptus oil smells fresh and feels light on the skin: Real eucalyptus oil has a clean, refreshing scent and a light texture that helps you enjoy its calming effects safely in the sauna.
Dilute the Oil Properly
- Always mix eucalyptus oil with water before use: Essential oils are very strong, so you need to dilute eucalyptus oil to make it safe.

- Don’t pour pure oil on sauna stones: Using undiluted oil can cause burning and strong fumes that bother you.
- Diluting oil helps prevent skin and breathing problems: Pure eucalyptus oil can irritate your skin and lungs, making sauna time uncomfortable.
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
- Pour diluted eucalyptus oil mixed with water on sauna stones: This is the most common way to release eucalyptus scent slowly and keep the aroma mild but lasting.
- Use a diffuser to spread eucalyptus scent fast and strong: Diffusers fill the sauna quickly with a strong aroma but need occasional cleaning.
- Place a small bowl of diluted oil near the heat source: This method steadily releases eucalyptus fragrance without needing extra tools.
- Put fresh eucalyptus leaves on the hot stones for natural scent: Fresh leaves heat up and release oils gently, creating a soothing and natural aroma without any cleanup.
- Never put eucalyptus oil directly on hot surfaces: Applying oil directly to hot stones or heaters can be unsafe and cause damage.
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.
