The invention provides a physical recovery cabin. The physical recovery cabin comprises a cabin body and a gas pressure regulating device, wherein the cabin body comprises a plate member, a frame member, a corner point member and a connecting member; the frame member comprises a groove used for containing the edge of the plate member, and the groove is internally provided with a first surface suitable for abutting against the edge of the plate member, so that when the pressure in the cabin body is stronger than that of the outside of the cabin body, the edge of the plate member can abut against the first surface to form air-tight connection.
