When we think about sauna in its modern form, we may think of elaborate bathhouses with elegant design, but in its simplest form, all that’s required for a healthy sweat is a heat source and a way of enclosing it. If our ancient ancestors were using fire as a tool a million years ago, it’s conceivable that with some rocks, sticks, and animal hides, they might have been having primitive sauna experiences as well. Given this, it is likely that sauna was not something that was “invented” at a single point in history so much as it “emerged into being” at similar times across cultures.
The Origins of Sauna
The actual word “sauna” originates from Finland, where it has been part of the Finnish lexicon over at least 2,000 years, suggesting the practice of sauna may have spread across groups of people in Northern Europe. Concurrently, the writings of the Greek historian Herodotus, nicknamed “The Father Of History,” identify the presence of established sauna culture in the Black Sea region over 2,400 years ago. Early saunas were simple pits dug into the ground, heated with stones to create warmth and steam. These saunas provided a vital refuge from the frigid winters of the region, offering a place to bathe and socialize. Over time, these pits evolved into wooden structures, and the sauna became central to Finnish life—not just as a bathhouse but as a sacred space for birth, healing, and spiritual rituals.
Sweat Bathing: A Universal Tradition
While colloquially “sauna” has evolved from denoting the Finnish tradition and into a catch-all term, the practice of sweat bathing itself is universal. Every circumpolar society (those living in the colder regions adjoining the North Pole) has some form of this communal heat therapy, and analogous traditions have been present in the American, the Mediterranean, Russian, and Asian societies for thousands of years as well. While the basic idea is the same, there are as many variations as there are cultures who have utilized the power of deep heat throughout history.
Russian Banya: In Russia, the banya emphasizes dry heat and the use of veniks—bundles of birch branches used to lightly whisk the body, stimulating circulation. The banya is a cornerstone of Russian wellness and community, blending relaxation with ritual.
Turkish Hammam: Originating in the Middle East, the hammam focuses on steam and ritualized cleansing. It traces its roots to Roman bathhouses and evolved into an essential part of Ottoman culture, offering a luxurious and meditative experience.
Indigenous Sweat Lodges: Across North America, indigenous peoples have used sweat lodges for centuries as sacred spaces for healing and spiritual ceremonies. These small, dome-shaped structures, heated with stones, symbolize purification and connection to ancestors and the natural world.
Mesoamerican Temazcal: In Central and South America, the temazcal has long been a practice for physical and spiritual renewal. Combining heat therapy with medicinal herbs and guided rituals, it reflects the interconnectedness of body, mind, and spirit.
Japanese Sentō and Onsen: In Japan, public bathhouses (sentō) and natural hot springs (onsen) are central to relaxation and rejuvenation. Though not saunas in the traditional sense, they share the sauna’s focus on cleansing, healing, and community.
Regardless of time and place, thermic bathers are united by a desire to cleanse, heal, and connect with one another and the surrounding environment.
While many wellness trends come and go, sauna bathing has stood the test of time, enduring as a practice for thousands of years. Today, sauna culture is thriving, with Finland leading the way with over 3 million saunas in a country of 5 million people. The country’s devotion to sauna is unparalleled, and for Finns, it remains a vital part of daily life—a space for both solitude and togetherness.
Saunas are also experiencing a worldwide resurgence, driven by a renewed appreciation for their physical and mental health benefits. From urban spas to mobile saunas that bring the experience into nature, more people are embracing the sauna as a means of finding balance in a fast-paced world.

A Tradition That Feels Like Home
If the origins of sauna are older than the written word, and perhaps even older than language, sauna is bridge to a practice that helped make us human. Perhaps this is why when we sit in the heat, whether sauna, badstue, or banya, there is a sense of arrival and a feeling of home, regardless of where we are or who we are with.
In the heat, there’s a feeling of homecoming—a connection to something ancient and enduring. It’s no wonder that sauna traditions have not only survived but thrived for thousands of years. They remind us of the power of simplicity: a heat source, an enclosure, and the human need to cleanse, heal, and connect.
