Sauna Ice Original provides a clean, raw, and intensely icy menthol experience that is maximally invigorating. Cold Plunge retains the icy coolness and clear airways, but adds a classic and rich eucalyptus scent (Eucalyptus globulus). Cold Plunge is the perfect entry-level product for those who want a proven, reliable, and iconic sauna scent that delivers exactly what it promises.

Unlike our original product, the crystals in Cold Plunge are enriched with a rich coating of 100% genuine essential oils. We use natural minerals to bind the oil around the menthol crystals, giving them a moist surface.

When you dissolve the crystals in hot water as instructed, the oils are released into the room with the steam without leaving stains or residue on the stones. However, avoid spilling oily crystals directly onto untreated wood on the sauna bench, as concentrated essential oils can cause temporary grease stains.

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 2-4 crystals.

The size of the crystals can vary. People can also react differently strongly to menthol, depending on how sensitive the cold receptors on your skin and in your airways are. If you are a person who easily feels cold, you might be more susceptible to menthol (cool, right?). The size of the sauna, its 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.

The essential eucalyptus oil in Cold Plunge has a long tradition in sauna culture and aromatherapy. Eucalyptus is known for its strongly refreshing properties, its ability to benefit the respiratory system, and for providing an immediate sense of purity and clarity.

L-menthol (menthol crystals) activates the body's cold receptors, TRPM8, in the skin and respiratory tract. These receptors normally react 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 a sauna bath, even though it is not a physical or medicinal decongestant. The subsequent effect is that our customers use the sauna more often, longer, and at higher temperatures, which has a significant and proven health benefit.

Menthol also has a proven effect of relieving dry coughs during and after a cold.

Yes, Sauna Ice Cold Plunge is completely safe to use as long as the user instructions are followed.

Our base consists of 100% natural menthol crystals enriched with pure essential oils. All our products are lab-tested and comply with strict EU regulations and chemical legislation (CLP).

However, because Cold Plunge is an extremely potent and concentrated product, there are some important safety rules to keep in mind for a safe and enjoyable experience. Read more about these further up under the heading "Information" or on the back of the pouch.

Our menthol is extracted from the wild mint plant (Mentha arvensis). This plant species is almost exclusively grown in India and is specifically used 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 saunas 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.

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 perceived as irritating to the skin or eyes, but this is then a reaction to the strength and not an actual allergy.

Cold Plunge contains pure essential eucalyptus oil. This adds the naturally occurring fragrance allergen Limonene. Individuals with a known contact allergy to this substance should exercise caution.

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, as long as it is used with water in accordance with the instructions. Ladle on as usual, and the next person to use the sauna won't even notice 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 largely water. 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?".

The oil blend in Cold Plunge consists of essential oil from pink grapefruit and bergamot. The oil is stabilized using fumed silica, which is a natural mineral with fantastic chemical properties for stabilizing liquids. This allows the oil to form a film around each individual crystal and remain stable without the oil and crystals separating.

Please consult a doctor. We have customers who have told us both how they cannot use Sauna Ice as it worsens their asthma, and about customers who can finally sauna together with their partner with asthma again thanks to Sauna Ice. If you are unsure how it will affect your specific asthma, we recommend not using Sauna Ice.

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.

Sauna Ice's oil-infused product line offers a completely unique sauna fragrance and is the first of its kind. The combination of a stabilized oil film around the menthol crystals creates a magical sauna experience.

The difference is that Sauna Ice menthol crystals are 100% pure, solid menthol, whereas common sauna fragrances are often diluted liquids. It provides a physically cooling sensation that opens up the airways and is significantly more potent than traditional sauna fragrances. With Cold Plunge, you get all the benefits of Sauna Ice Original with added fragrance and health effects from carefully selected essential oils.

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. Menthol is a very economical product where only 20 grams is enough for many sauna sessions. Packaging small bags with only a few crystals is technically very difficult due to the size of the bag and the heat sensitivity of the crystals.

Yes! Sauna Ice is excellent for use in humidifiers and aroma diffusers to spread a lovely menthol scent in the room and provide a feeling of easier breathing. Vacuuming up a few crystals gives a similar effect. Sauna Ice can also be used for foot baths and in the bathtub (for those who dare!).
