a good old sauna. Finlandia style...in the woods, heated up by a wood burner instead of electricity, with a nearby lake to take a skinny dip in,with a good cold beer to sip,... haaaaa could go right now.
Sometimes people make a vasta (or vihta); they tie together small fresh birch branches (with leaves on) and swat themselves and their fellow sauna bathers with it. Vihtas can even be bought from a shop and stored into a freezer for later (winter) use. Using a vasta improves blood circulation, and its birch odour is considered pleasing.
The entrance to the smoke sauna door. The door handle is a moose antler. Note the birch whisk (vihta) hanging on the wall, with which we smote ourselves! In the heat of the sauna, the vihta produces a wonderful herbal smell.
