Smoke rises from the sauna as Eda Veeroja walks past with birch twigs at Mooska farm near the village of Haanja December 20, 2014. Smoke saunas are usually built without chimney and have a stove that rest on boulders where firewood is burnt until the room heats up. When the smoke is gone and the room reaches the right temperature, people sit inside and whisk each other with birch twigs. The tradition of the smoke sauna in Voromaa vicinity, in the south of Estonia, is enlisted in the UNESCO representative list of the intangible cultural heritage of humanity.
