The sauna has dim lighting; talking is forbidden, and everyone sits quietly and comfortably. The temperature is usually between 80°C and 110°C. Some people tie together birch branches with leaves on them to make a 'vihta' and gently tap their skin with it. Vihtas are also sold in shops and can be stored in the refrigerator for use in winter.
Vihta is said to stimulate blood circulation, and the scent of birch is refreshing.
Once the desired temperature is reached, the smoke is cleared from the room, and those wishing to bathe enter. The scent of burning wood lingering in the room is part of the cleansing ritual. This type of fragrant bath is called savusau-na (smoke sauna) in Finnish.
"Many people find the smell of smoke and wood relaxing.
In traditional Finnish saunas, swimwear, towels, or wraps are rarely worn; nudity is not taboo in this society. Families go to the sauna together; this is an old tradition, and many families have their own private saunas.
In public saunas, there are separate sections for men and women. Saunas are not seen as related to sexuality; for the Finnish people, the sauna is considered the most sacred place after the church. Until the beginning of the 20th century, many Finnish women gave birth to their children in saunas, which were considered a warm and clean environment."
