Sauna from the Wikifile: The word sauna is an ancient Finnish word referring to the traditional Finnish bath and to the bathhouse itself. In Baltic-Finnic languages other than Finnish, sauna does not necessarily mean a building or space built for bathing. It can also mean a small cabin or cottage, such as a cabin for a fisherman.^[4]
  

<sup>A sauna (/ˈsɔːnə/ [1] or /ˈsaʊnə/;[2][3] Finnish pronunciation: [ˈsɑunɑ]) is a small room or house designed as a place to experience dry or wet heat sessions, or an establishment with one or more of these and auxiliary facilities. The steam and high heat make the bathers perspire. Saunas can be divided into two basic styles: conventional saunas that warm the air or infrared saunas that warm objects. Infrared saunas may use various materials in their heating area such as charcoal, active carbon fibers, and other materials.

I was first introduced to "sauna" in high school. Our headmaster was Sweedish. In his ambitions, he had the woodsmen/women team build a log cabin sauna, complete with a one sided deck, changing room. and year round outside shower. It was the cats meow. 

Later in life after hard winters, working in dairy barns, sore muscles I started swearing that I would "NOT GO THROUGH ANOTHER VERMONT WINTER" without a sauna. We have finally arrived at that place in life, where we have our spot on planet earth, and built ourselves a sauna. 

In addition to the definitions of sauna, I was taught that one of the objects is to draw your blood out to  the epidermis, making your skin a breathing organ, and oxygenating your blood. We do this by heating for ten to fifteen minuets and then cooling, in a series of three to four heating sessions. 

For us, sauna happens on Sunday night. It is a chance to gather ourselves prior to the week starting. It is a chance to let out toxins, reinvigorate, and fill up on fluids. It is a spiritual space collecting ourselves, and cleaning ourselves from the inside out.</sup>
