An apparatus for a sauna includes a first and second heating element. The first heating element has a first conductive path and is coupled to pass a current. The second heating element has a second conductive path that runs adjacent to the first conductive path. The second heating element substantially blocks an electric field produced within the first heating element. The first conductive path is coupled to redirect the current to the second conductive path and set up complementary magnetic fields between the first and second heating elements.

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.

A soaking device and methods of using are used to cool and/or to heat a face of a person for a purpose of inducing a desired and/or intended outcome in that person. The cooling and/or the heating of the face may be sufficient to induce the desired and/or the intended outcome in that person. The desired and/or intended outcome may relate to: release of at least one type of neurotransmitter; trigeminal nerve stimulation; (indirect) vagus nerve stimulation; transdermal drug delivery; bypass of the blood-brain-barrier (BBB); aesthetic medicine; cardiovascular; dermatological; ears, nose, and throat (otolaryngological); ophthalmological; neurological; psychological; endocrinological; and/or rheumatological benefits to that person. At least one step of the method may include receiving at least some of the face within an immersion-liquid for at least a minimum amount of time while the immersion-liquid is within a temperature-range and while the immersion-liquid is within the soaking device.

An example sauna stove can include an open-air container with a plurality of sides and is open at the top, a heat-conductive plate that includes a first surface that acts as a side to the open-air container and a second surface opposite the first surface, an electric heating element that is positioned on the second surface of the heat conductive plate, and a furnace chamber that utilizes the second surface of the heat-conductive plate as a surface to transfer heat generated by the furnace chamber to the open-air container.

A wood burning sauna stove includes an outer frame and a firebox inside the outer frame. The outer frame includes an upper frame wall, a front frame wall, a rear frame wall, and lateral frame walls connecting the front frame wall and the rear frame wall. The upper frame wall is designed to support sauna rocks. The firebox includes an upper firebox wall, a lower firebox wall, and a perimeter firebox wall. The perimeter firebox wall includes front, rear, and side firebox walls. An exhaust conduit is positioned between the upper frame wall and the upper firebox wall to heat the upper frame wall and the sauna rocks on the upper frame wall. The exhaust conduit has an exhaust inlet aperture in the upper firebox wall adjacent the front firebox wall and an exhaust outlet aperture in the upper frame wall adjacent the rear firebox wall.
