Why You Shouldn’t Wear a Swimsuit in the Sauna
Although it may feel unusual at first, if you are not used to it, traditional sauna culture encourages entering without swimwear. This is not about nudity—it is about hygiene, safety, and proper heat exchange. Wearing synthetic fabrics in high temperatures can be harmful to your body and to the sauna environment.
1. Health and Hygiene
Swimsuits are usually made of nylon, polyester, or elastane—all synthetic materials that trap sweat, block pores, and can release micro-toxins when heated. A clean cotton towel allows your skin to breathe freely and keeps the benches hygienic. At Emerald Spa, our sauna (and other areas) are clothing optional. If you do wish to cover up, then it’s best to use a thin cotton wrap and sit on a clean towel. (We can provide everything you need). And dont worry about the aroma of sweat either – all our sauna sessions include aromatherapy premium-quality essential oils in the steam/water put onto the hot-stones in the sauna, ensuring a wonderful, inspiring and relaxing environment.
2. Effective Heat Transfer
Sauna heat works best when it contacts the skin directly, encouraging even sweating and detoxification. A swimsuit prevents this process and can cause uneven heating, making your session less effective. Scientific research confirms the health benefits of airing your whole body and letting your body sweat.
3. Cultural Respect and Comfort
In countries such as Finland, Germany, and Poland, textile-free saunas are normal and non-sexual. Towels are used to sit on for hygiene and modesty. This natural approach promotes equality and comfort, removing the focus from appearance and returning it to wellbeing.
At Emerald Spa, guests are invited to embrace authentic sauna etiquette—wrapped in a towel, or nude, relaxed, and free to experience the full cleansing power of the heat.
