Saunas originated in European countries with colder climates some 2,000 years ago — the traditional Finnish saunas preceded the Estonian, Russian, and Latvian sweat baths, and is the style of sauna that is still the most popular today. Primitive and functional, they were built into a mound of earth and heated by a fireplace with sauna stones to throw water over. Over the years, the technology changed and designs evolved (you can even get your hands on a gondola converted into a sauna), but the traditional Finnish sauna remained as a way of life and ritual in Nordic and Scandinavian culture. Today, saunas are still considered a regular part of everyday life that improves wellbeing, promotes relaxation, and offers a communal space to gather and simply be. In public, sauna etiquette usually means being respectful of other bathers’ peace and quiet, always sitting on a clean towel, and of course, giving a nod or grunt if you fancy pouring more hot water over the sauna stone.
