Lava stones, also known as volcanic rocks, have long been a cornerstone of the traditional sauna experience. These porous, rugged stones are not just ordinary rocks; they carry a unique blend of natural energy and cultural significance that enhances the sauna ritual. In this article, we'll explore the role of lava stones in saunas, their benefits, and how they contribute to the overall sauna experience.
Lava stones are formed from volcanic activity, where molten lava cools and solidifies into these distinct, porous rocks. Their formation involves intense heat and pressure, which infuses them with unique properties such as high heat retention and the ability to withstand extreme temperatures. This makes them an ideal material for use in saunas.
Historically, lava stones have been used in various cultures for their believed healing and spiritual properties. In the context of saunas, these stones have been cherished for their ability to create a consistent and gentle heat, transforming the sauna into a place of relaxation, detoxification, and rejuvenation.
In a sauna, lava stones are typically placed atop the sauna heater, where they play a crucial role in the heat and steam generation process. When water is poured over these hot stones, it instantly vaporizes, creating the characteristic burst of steam known as löyly in Finnish tradition. This steam enhances the humidity in the sauna, intensifying the heat and providing that soothing, enveloping warmth that sauna enthusiasts seek.
The porous nature of lava stones allows them to hold and release heat slowly, ensuring a steady and prolonged heat distribution within the sauna. This slow release is essential for maintaining a comfortable and consistent temperature, which is key to a relaxing and therapeutic sauna session.
Heat Retention and Distribution: Lava stones are excellent at retaining and gradually releasing heat. This ensures that the sauna remains warm for extended periods, providing a consistent and enjoyable experience.
Durability: These stones can withstand the extreme temperatures and rapid heating-cooling cycles that occur in saunas. Their resilience means they last longer, reducing the need for frequent replacement.
Enhanced Steam Quality: The steam produced when water contacts hot lava stones is soft and soothing, creating a more comfortable atmosphere. The steam also carries heat evenly throughout the sauna, making the environment more therapeutic.
Natural Purity: Lava stones are a natural product, free from any artificial chemicals or treatments. This purity ensures that the air in the sauna remains clean and free from harmful emissions.
Aesthetic Appeal: The rugged, earthy appearance of lava stones adds to the natural ambiance of the sauna, contributing to the overall aesthetic and making the sauna experience more immersive.
To ensure that lava stones continue to function effectively in a sauna, proper care and maintenance are essential. Over time, the constant heating and cooling, as well as the exposure to water, can cause the stones to crack or break down. It's recommended to periodically inspect the stones for any signs of wear and replace them as needed.
Additionally, it's important to avoid using too much water at once when creating steam, as this can cause thermal shock to the stones, leading to cracking. Instead, water should be poured slowly and evenly over the stones.
Lava stones are much more than just a heating element in a sauna—they are the heartbeat of the sauna experience. Their natural properties of heat retention, durability, and ability to generate soothing steam make them indispensable in creating the perfect sauna environment. Whether you're seeking relaxation, detoxification, or a deep connection to ancient traditions, the use of lava stones in your sauna can elevate the experience, making each session a journey of rejuvenation and well-being.
