Using aromatherapy in a sauna isn't just about making the room smell nice. It's about transforming your session into a multi-sensory journey that can enhance your mood, support your respiratory system, and deepen your relaxation. Think of it as upgrading your sauna from a simple heat session to a personalized wellness ritual. This guide will walk you through everything you need to know about how to use sauna oil safely and effectively, turning your next sauna into your best one yet.
What Exactly Is Sauna Oil?
At its core, sauna oil is a concentrated aromatic liquid, typically made from essential oils, designed to be diffused in the high heat of a sauna. When you add water to the hot stones of a traditional Finnish sauna, it creates a burst of steam called löyly. Adding sauna oil to that water infuses the steam with fragrant, therapeutic compounds that fill the entire room.
It’s important to know that "sauna oil" can refer to two things:
Pre-diluted sauna scents: These are products specifically formulated for sauna use, often containing essential oils already mixed with a carrier like alcohol or water.
Pure essential oils: These are potent plant extracts that you dilute yourself before using. Using pure essential oils gives you more control over the scent and therapeutic properties.
For our purposes, we'll focus mostly on using pure essential oils, as they offer the most flexibility and benefits. You aren't just adding a fragrance; you're unlocking the power of plants.
Dilution is Non-Negotiable
You should never, ever drop pure essential oils directly onto hot sauna stones. Essential oils are highly flammable, and applying them directly to a hot surface is a serious fire hazard. Not only that, but the intense heat will "flash burn" the oil, destroying its delicate aromatic compounds and creating a harsh, unpleasant smell instead of a therapeutic one.
The proper method is always to dilute the oil in water. This ensures the sauna aroma is released gently and safely with the steam, allowing you to breathe in all the natural goodness.
The Benefits of Using Essential Oils for Sauna
Adding aromatherapy to your sauna does more than just delight your senses. The combination of heat and specific essential oils creates a synergistic effect, amplifying the wellness benefits of your session.
Deep Relaxation and Stress Relief
The most common reason people use a sauna is to unwind. Certain scents have a direct impact on the nervous system. Lavender, for example, is well-known for its calming properties. When you inhale its aroma in a warm, peaceful environment, you’re signaling to your brain that it’s time to switch off the stress response and enter a state of deep relaxation.
Respiratory Support
The steam in a sauna is already great for opening up your airways. When you add oils like eucalyptus or peppermint, you enhance this effect significantly. These oils contain compounds like eucalyptol and menthol, which act as natural decongestants. Inhaling this infused steam can help clear your sinuses, soothe a scratchy throat, and promote easier breathing. It’s a fantastic ritual if you're feeling congested or dealing with seasonal allergies.
Mood Enhancement and Mental Clarity
Feeling a little down or mentally foggy? Citrus oils like sweet orange, lemon, or bergamot are your best friends. Their bright, zesty aromas are natural mood lifters. Research from the National Center for Biotechnology Information (NCBI) suggests that certain essential oils can have a positive effect on mood and can help alleviate symptoms of anxiety and depression. A sauna session with an uplifting oil can leave you feeling more positive, focused, and mentally refreshed.
Post-Workout Recovery
If you use the sauna to recover after exercise, the right oils can help. Peppermint can create a cooling sensation that soothes tired muscles, while oils like spruce or pine can help ease minor aches and pains with their anti-inflammatory properties. The heat improves circulation to your muscles, and the oils enhance the feeling of relief and recovery.
How to Choose High-Quality Sauna Oils
Not all essential oils are created equal. Since you’ll be inhaling these compounds, quality is paramount. Here’s what to look for:
Purity: Look for oils that are 100% pure, with no synthetic fragrances, fillers, or additives. The label should clearly state this.
Botanical Name: A reputable brand will list the Latin botanical name of the plant (e.g., Lavandula angustifolia for Lavender). This ensures you're getting the correct species with the desired therapeutic properties.
GC/MS Testing: The gold standard for quality is Gas Chromatography/Mass Spectrometry (GC/MS) testing. This third-party analysis verifies the oil's purity and chemical makeup. Brands that make these reports available are usually trustworthy.
Dark Glass Bottles: Essential oils degrade when exposed to light and heat. Always buy oils that are packaged in dark amber or cobalt blue glass bottles to protect their integrity.
Avoid "fragrance oils" or "perfume oils." These are synthetic and lack the therapeutic benefits of true essential oils. They can also release harmful chemicals when heated.

A Step-by-Step Guide to Using Sauna Oil
Using sauna oil is simple, but the method can vary slightly depending on your sauna type. Remember, sauna safety is always the top priority.
For Traditional Finnish Saunas
This is the classic method for creating an aromatic steam bath.
Prepare Your Water: Fill your sauna bucket with cool, fresh water.
Add the Oil: Add 3-5 drops of your chosen essential oil or blend to the water. A little goes a long way!
Stir Gently: Give the water a gentle stir with your ladle to disperse the oil.
Create the Steam: Once your sauna stones are fully heated, ladle the scented water onto them. Pour a small amount at a time to create a gentle, fragrant steam. Avoid dumping the whole bucket at once.
Breathe Deeply: Sit back, relax, and inhale the therapeutic aroma.
For infrared saunas
infrared saunas heat the body directly and typically don't use water or steam. You'll need a different method here.
Use a Small Bowl: Place a small, heat-safe ceramic or glass bowl of water in your sauna. Add a few drops of essential oil to the water. The ambient heat will gently warm the bowl and diffuse the scent throughout the space.
Use a Passive Diffuser: You can also use a simple terracotta or sandstone diffuser. Add a few drops of oil to it and place it in a corner of your sauna.
Do not place oils directly on infrared heaters or any surfaces that get hot.
For Steam Rooms or Steam Showers
Steam rooms are already full of moisture, making them perfect for aromatherapy.
The Bowl Method: Similar to an infrared sauna, place a bowl of cool water with a few drops of oil inside the steam room. The steam will mix with the aroma and circulate it.
The Washcloth Method: Add a few drops of oil to a damp washcloth and place it on a bench or hang it away from direct steam outlets. As the room heats up, the scent will be released.
Sauna Safety and Important Precautions
While aromatherapy in sauna is generally safe, there are some important guidelines to follow to ensure a positive experience.
Always Dilute: As mentioned, never apply oils directly to hot rocks or heating elements.
Ensure Good Ventilation: Make sure your sauna has proper ventilation to prevent the aromatic compounds from becoming overwhelming. If you start to feel lightheaded or nauseous, exit the sauna immediately.
Skin Sensitivity: Essential oils are potent and can cause skin irritation if they come into contact with your skin undiluted. Wash your hands after handling the oils.
Pregnancy and Health Conditions: If you are pregnant, nursing, or have a serious health condition like epilepsy or high blood pressure, consult with your doctor before using essential oils. For more on essential oil safety, an overview from Johns Hopkins Medicine provides helpful context.
Children and Pets: Be extremely cautious when using essential oils around children and pets, as they are much more sensitive. Some oils are toxic to animals. It's often best to avoid using them in a sauna that pets or young children might enter. The CDC offers information on respiratory health related to flavorings and scents that highlights the importance of air quality.
Keeping Your Sauna Clean
Using sauna oils can sometimes leave a slight residue over time. To keep your sauna fresh and clean:
Wipe down benches with a damp cloth after each use.
For a deeper clean, use a mild solution of water and white vinegar to clean wooden surfaces.
If you use a diffusion bowl, wash it regularly with soap and water to prevent oil buildup.
Ensure your sauna bucket is emptied and dried after use to prevent mold.
By incorporating sauna oil into your routine, you’re not just adding a pleasant scent; you are actively enhancing your physical and mental well-being. It’s a simple act that transforms a good experience into a great one.
So next time you prepare for a session, take a moment to choose an oil that matches your intention. Whether you need to breathe easier, relax deeper, or feel more energized, the right sauna aroma can help you get there. Why not start tonight?
