Sauna is one of the oldest rituals of returning to the elements. Fire heats stone, water rises as steam, air fills the lungs, skin opens to release. Wood carries the scent and spirit of the forest into the room. The sauna is a place of purification and community, a reminder that healing begins when we meet the world stripped back to essentials. Here, we become naked and authentic. For Experience Aika, sauna is both practice and inspiration: a design where the Four Elements and body merge.
