Sauna etiquette varies by culture and setting — here is a clear, practical guide.
The Finnish Way: Nothing or a Towel
In Finland, where sauna culture was born, the traditional approach is to sit unclothed on a towel. This allows your skin to breathe fully, sweat freely, and benefit maximally from the heat. The towel protects the bench.
Swimwear
In public or shared saunas, swimwear is standard and perfectly appropriate. Choose natural fabrics like cotton — synthetic materials like nylon or polyester trap heat against your skin and can become uncomfortable or even harmful at high temperatures.
What to Avoid
Tight synthetic fabrics (nylon, polyester, spandex). Underwire bras — metal heats up. Heavy fabrics that hold water and weight. Shoes or socks — bare feet only.
Accessories
A sauna hat (traditional felt or wool) helps protect your head from the most intense heat near the ceiling. A wooden headrest keeps your face off the hot bench. Both are worth having for longer sessions.
The Simple Rule
Wear as little as your comfort and setting allow. The sauna works best when your skin is unobstructed.
