Dry salt air has been used for respiratory comfort for a very long time, and we make no medical claims about it. What we can say is that the room is the quietest space in the building and that forty-five minutes of counted breathing inside it does something to people that forty-five minutes of counted breathing at home does not.

The session runs in three parts. The first fifteen minutes lengthen the exhale — you will be counted into an out-breath roughly twice the length of the in-breath, which is the single most reliable way to move a nervous system out of its alert setting. The middle fifteen drop the count entirely and simply hold the room quiet. The last fifteen bring the breath back to something ordinary before you stand up, which matters more than it sounds; standing up from deep work too quickly is how people get dizzy.

You stay clothed and reclined. Wear something you would not mind a fine salt dust settling on — it brushes off, but dark wool holds it. The guide speaks little and never over the top of you, and there is no participation of any kind expected beyond lying still.

We run it on Thursday evenings and Sunday mornings, capped at eight chairs, because a salt room with twelve people in it is a room with coughing in it. It is the cheapest thing we sell and the one most likely to be rebooked on the way out.
