Place the crystals in the sauna ladle along with hot water (over 42 degrees Celsius). Let them melt for a few seconds and then pour onto the hot stones. Lean back, breathe, and enjoy!

As a general guide, we usually say 2-5 crystals, the size of a grain of rice.

The size of the crystals can vary. People can also react differently to menthol, depending on how sensitive the cold receptors on your skin and in your airways are. If you are a person who gets cold easily, you may be more susceptible to menthol (cool, right?). The size of the sauna, the heat, and the effect you are looking for also play a role.

Experiment and find the dosage that suits you best!

The sauna is and should be hot! Menthol binds to the body's cold receptors and tricks the brain into thinking it's cold. The effect is an incredibly intense contrast where the brain receives signals that it is both hot and cold at the same time. Imagine taking a sauna > ice bathing > taking a sauna again, but all at once. One customer described it as sitting in a throat lozenge, which is quite descriptive.

Yes! Menthol has been used in many forms by humans for hundreds of years and is generally considered safe. Our menthol crystals are lab-tested and approved according to EU regulations. Menthol allergy occurs, albeit very rarely. If you know you are allergic or very sensitive to menthol, we do not recommend using Sauna Ice. High doses can also lead to eye irritation. Remember that Sauna Ice is an extremely potent product, and use it accordingly. Follow the instructions and guidelines. Avoid direct skin contact with the crystals.

Sauna Ice is a 100% natural product extracted from the wild mint plant (Mentha arvensis). This plant species is cultivated almost exclusively in India and is used specifically for its naturally high content of L-menthol, which enables a very pure end product. The production takes place through a natural separation process:

1. Extraction: First, the essential oil is extracted from the wild mint leaves through steam distillation.
2. Crystallization: The oil is gradually cooled in a controlled manner. The pure menthol separates from the remaining oil and forms solid, transparent crystals of pure L-menthol.
3. Centrifugation: The crystals are separated from the remaining liquid in a centrifuge.
4. Sorting: The perfect crystal size for sauna use is sorted out, and the remaining crystals find more suitable homes in other products such as nasal sprays, throat lozenges, skincare, baked goods, and chewing gum.

The result is a 100% natural product with a very short ingredient list: menthol.

Dry and cool! Never store Sauna Ice in the sauna. Moisture can make dosing more difficult if it becomes sticky in the bag/jar. Sauna Ice has a melting point of 42 degrees Celsius. If you have a bag or jar in the sauna, it will melt quickly. When it then solidifies at lower temperatures, the menthol will not recrystallize but will become a single menthol cake. The product is not ruined as the effect is unaffected by this, but it becomes significantly more difficult to dose as you have to break, scrape, or chop off pieces.

Always store Sauna Ice at room temperature as its melting point is 42 degrees Celsius. If it has melted into a menthol cake, its function remains unchanged, but to continue dispensing it easily, you can do one of the following:

1. Break it into small pieces with a mortar and pestle or a hammer. Store in an airtight glass jar.
2. Scrape pieces of the menthol cake with a metal spoon directly into the bucket or pail.
3. Continue storing the menthol, tightly sealed, in the sauna. As the sauna heats up, the menthol will melt again. You can then drip the desired amount into the bucket or pail. If you choose this method, be very careful not to drip it on the floor, sauna benches, or get the menthol on your skin, as it can easily spread to more sensitive parts of the body.

Besides smelling magical, Sauna Ice menthol crystals have the effect of cooling the skin and opening the airways! When you throw Sauna Ice on the rocks with water, the menthol spreads with the steam, over your skin and into your airways as you breathe. As soon as the water hits the rocks, you'll smell the scent; after 5-10 seconds, you'll notice that breathing becomes easier, and after 20-30 seconds, you'll feel a noticeable coolness on your skin.

Yes, but it is very rare. What people often mistake for menthol allergy is in fact a reaction to substances like carvone or limonene. These are found in, for example, spearmint (common in toothpaste), but are not present in the menthol crystals from field mint used in Sauna Ice. At very high concentrations, menthol can be irritating to the skin or eyes, but this is a reaction to its strength and not an actual allergy.

Yes! Sauna Ice is a strong product, but about 15 minutes after use, 90% of the scent should be gone. No residue will remain on the stones either. Good sauna etiquette dictates that you ask your sauna neighbours if it's okay with them for you to use Sauna Ice before use.

Yes! Sauna Ice is a strong product, but about 15 minutes after use, 90% of the scent should be gone. No residue will remain on the stones either. Good sauna etiquette dictates that you ask your fellow sauna-goers if they are okay with you using Sauna Ice before use.

No! Sauna Ice leaves no residue on the stones. Pour as usual and the next person to use the sauna won't notice that you've used Sauna Ice.

Yes! A wood-fired sauna with Sauna Ice is a perfect combination. The king of saunas with the king of sauna fragrances.

Yes! Follow the instructions and avoid throwing directly onto the heating coils.

Hmm... Since there's no heater to throw water on, you'll need to be a bit creative. We've had some customers with infrared saunas who bring a mug of hot water into the sauna and add Sauna Ice to it. You won't get the cooling effect on your skin, but you will get easier breathing and a wonderful scent!

Sauna Ice menthol crystals are guaranteed to be ~99.9% pure L-menthol. The remaining 0.1% is difficult to guarantee but is most likely water for the most part. The crystals are produced through a natural separation process of wild mint leaves. Read more about this under the question "How is Sauna Ice produced?".

Sauna Ice has no direct health benefits, but: L-menthol activates the body's cold receptors, TRPM8, on the skin and in the airways. These receptors normally respond to cold, and when stimulated by menthol, the brain perceives the air as cooler and the airways as "opening up". This provides a strong subjective feeling of freer breathing and increased comfort during the sauna session, even though it is not a physical or medicinal decongestant. The resulting effect is that our customers sauna more often, longer, and hotter, which has a significant and proven health benefit.

Menthol also has a proven effect in alleviating dry coughs during and after colds.

Please consult a doctor. We have customers who have reported both that they cannot use Sauna Ice as it worsens their asthma, and customers who can finally sauna with their partner with asthma again thanks to Sauna Ice.

Physically, Sauna Ice menthol crystals do not facilitate breathing, but the cold receptors in the airways react to the menthol, creating a strong sensation of easier breathing for most people.

Yes. Menthol, like all other oils, has a natural flash point and an autoignition point. Although it's unlikely, it's possible for example that a large crystal falls among the stones and heats up to the point of autoignition, creating a 10-15 cm high flame. There is no danger as it burns up quickly and is easy to extinguish with a scoop of water, but it can be perceived as unpleasant. If you use warm water with Sauna Ice, the crystal will melt, distribute evenly over the stones, and the risk is then virtually nonexistent.

The difference is that Sauna Ice is 100% pure menthol in solid form, whereas regular sauna scents are often diluted liquids. It provides a physically cooling sensation that opens up the airways and is significantly more potent than traditional sauna scents.

To summarize a very long answer briefly, we do a number of things to guarantee optimal use for the sauna. You will be hard-pressed to find menthol crystals that are better suited for the sauna than Sauna Ice menthol crystals.

Sauna Ice should only smell of menthol. If it smells strange, the culprit is most likely one of the following:

1. Dirty stones: If it's been a long time since you cleaned the stones, many years of dirt accumulated on the sauna stones can be dissolved by the menthol crystals and carried with the sauna steam. Consider it your reminder to rinse the stones with a pressure washer every two years!
2. Non-pure water: If you use e.g., lake water, you might accidentally introduce something into it that lands on the stones.
3. Plastic from the packaging: Did you just open the bag and perhaps tear off a piece of plastic that went into the scoop? Not very likely perhaps, but it has happened to at least one customer that I know of!

Yes, but be careful! Sauna Ice is extremely potent. Children are more sensitive and the menthol can be unpleasant. Avoid using it completely if children under 3 years old are in the sauna.

The product never becomes bad or dangerous, but its effect diminishes over time. We usually use 2-3 years as a benchmark, but if it's not stored airtight, that time is significantly shorter.

No, unfortunately not. Sauna Ice is a very potent product where only 20 grams is enough for many, many sauna sessions. Packaging small sachets with only a few crystals is technically very difficult due to the size of the sachets and the crystals' heat sensitivity.

Yes! Sauna Ice can be used in humidifiers and aroma diffusers to spread a wonderful menthol scent in the room and provide a feeling of relieved breathing. Vacuuming up a few crystals provides a similar effect. Sauna Ice can also be used for foot baths and in the bathtub (for those who dare!). There is research on increased running performance through long, warm baths. Here, Sauna Ice can be a key to enduring 40+ degree hot water for 30+ minutes.
