Saunas have a long and rich history that spans many cultures and regions around the world. The earliest known saunas were used in ancient Finland, where they were called "savusaunas" and were used as a means of both bathing and healing.
Over time, saunas spread to other parts of Europe and eventually to other parts of the world, where they were adapted to local customs and traditions. For example, in Russia, saunas were known as "banyas" and were used for purification rituals, while in Japan, saunas were called "mushiburo" and were used as a means of relaxation and stress relief.
In many cultures, saunas were viewed as sacred spaces, where people could cleanse themselves both physically and spiritually. They were often used as part of religious or cultural rituals, and were sometimes even believed to have magical or mystical powers.
Today, saunas are popular all over the world, and are used for a variety of purposes, including relaxation, stress relief, and health and wellness. There are many different types of saunas available, including traditional wood-fired saunas, electric saunas, and infrared saunas, each with their own unique benefits and features.
