Systems and methods are provided for controlling infrared radiation (IR) sources of a sauna including tuning IR wavelength-ranges and radiated power-levels of IR sources, and directing IR to locations on a user's body. In one illustrative embodiment, a sauna may be provided having adjustable heat sources to emit IR at any wavelength resulting in a desirable radiation treatment for the sauna user. In another illustrative embodiment, a method is provided for tuning IR sources in a sauna.

Systems, devices, and methods are disclosed herein for ultraviolet saunas. Systems include a plurality of walls of an enclosure, the enclosure being a sauna enclosure configured to accommodate a user. The systems further include a plurality of heating elements coupled to the plurality of walls, a plurality of emissive elements configured to generate ultraviolet (UV) light, and a controller coupled to the plurality of heating elements and the plurality of emissive elements. The controller includes one or more processors configured to generate activation properties for each of the plurality of heating elements and the plurality of emissive elements, activate at least one of the plurality of heating elements based on the plurality of activation properties, and activate the at least one emissive element based on the plurality of activation properties.

An apparatus, method and computer program of heating a sauna sweat room for providing a comfortable temperature and environment in the sauna sweat room for a pleasant sauna experience. The apparatus includes a heating unit comprising a heat accumulator and a duct for collecting a hot air and a cool air and enabling the mix of the collected hot and cool air for providing homogenous temperature in the sauna sweat room. The method includes receiving the hot air heated by the heat accumulator in the at least one duct, receiving in the at least one duct the cool air, mixing the received hot air with the received cool air to obtain a mixed air stream, directing at least part of the mixed air stream towards a lower section of the sauna sweat room via the second end of the at least one duct.

The cabin (1) for wellness treatments, particularly saunas, steam baths and the like comprises: a containment structure (2) comprising a plurality of walls (3) coupled to each other and defining at least one treatment space (4) adapted to accommodate at least one user, the plurality of walls (3) comprising at least one access wall (3a) for the access to the treatment space (4), at least one back wall (3b) opposite the access wall (3a), and at least one pair of side walls (3c, 3d) opposite each other and located between the access wall (3a) and the back wall (3b); and at least 2 one air conditioning system (6) of the treatment space (4) comprising at least heating means (7) and at least one electronic management and control unit (U) of the heating means (7): in which the air conditioning system (6) is associated with the back wall (3b), each of the side walls (3c, 3d) being devoid of the heating means (7) and of the electronic management and control unit (U).

The disclosure relates to backlit wall covering for a sauna with wood lamellae arranged spaced from one another and fastened to slats spaced from one another. A diffuser is adhesively bonded onto the rear sides of the wood lamellae.

A personal therapy compartment includes a base of size to receive a human patient. The compartment includes a bed in the base said bed being made of a light transmissive material. An array of lights mounted is below the bed to transmit light onto a body supported on the bed. A control panel controls at least the wavelength, intensity and pulsation of the light.
