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.

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.

In addition to having a magical scent, Sauna Ice menthol crystals have the effect of cooling the skin and opening the airways! When you throw Sauna Ice onto the stones 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 stones, you will smell the scent, after 5-10 seconds you will notice that breathing becomes easier, and after 20-30 seconds you will 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.

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. The crystals are produced through a natural separation process of wild mint leaves.

Sauna Ice is suitable for both wood-fired and electric saunas. It also works perfectly for use in gyms, swimming pools, or other public saunas. The scent lingers for about 15 minutes and leaves no residue. If there are others in the sauna, it is good sauna etiquette to ask your fellow bathers before using Sauna Ice or other fragrances.

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.

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.

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.
