You close the door. You turn off the light. You lie down.
For the next 8 hours, you will do nothing. But the room around you will be doing a lot.
The door is closed. The window is closed. Nothing is circulating.
The bedding industry calls this the "recovery chamber." What it actually is, is eight closed-door hours in the same small volume of air.
And unlike every other room in your house, you don’t have to DO anything to be exposed. You just have to breathe.
