A spine cooling device is configured to hold the evaporative cooling textile in contact with a wearer's skin, particularly in a location between the wearer's hips and extending toward the wearer's tailbone. The spine cooling device has a pocket to hold the evaporative cooling textile, which textile can be periodically re-wetted while the spine cooling device remains in place on the wearer. The spine cooling device facilitates direct contact between the evaporative cooling textile and the wearer's skin, and is worn beneath the wearer's clothes. However, the device includes a water resistant layer placed to prevent the evaporative cooling textile from wetting the wearer's clothes.

A heat sleeve for selectively heating a residual limb of an amputee is provided. The heat sleeve includes a first sock member having an open proximal end, a distal end and a continuous side wall, all defining an open interior area configured to receive the residual limb therein. A temperature regulating apparatus includes a thermal adjustment element adapted to be mounted onto an exterior surface of the first sock member proximate the distal end, and a power supply operatively coupled to the thermal adjustment element. When the power supply is in its ON orientation and providing power to the thermal adjustment element, the thermal adjustment element selectively heats the residual limb within the first sock. A second sock member may then receive the residual limb, the first sock member and the flexible heating element therein.

Disclosed is a cooling device, including a housing having a wall; a reservoir within the housing; a cooling material such as a liquid or gel in the reservoir; a pump within the housing; and a conduit passing adjacent the wall and through which the material is circulated by the pump from the reservoir back to the reservoir.

Disclosed are devices and methods for mitigating insulin resistance in a human subject by contacting one or more regions of the neck, the supraclavicular, and the interscapular regions of the human subject with a part of a cooling device, wherein the part of the cooling device has a temperature at about 15 or less Celsius degrees; cooling the one or more regions of the neck, the supraclavicular, and the interscapular regions of the human subject for a cooling period of at least 15 minutes; and performing previous two steps daily for about 14 or more days. The devices and methods may also be used to preventing, delaying or treating type 2 diabetes in a human subject or activating brown fat without incurring a sympathetic nerve-mediated cold feeling in a human subject.

A heat exchanger cap, and method of manufacture of a heat exchanger cap configured to conform to a human head the cap comprising a first element for covering one side of the head; a second element for covering the other side of the head; and an intermediate joining element joined to, and which spaces apart, the first element and second element. Each of the elements define a single passageway for the passage of fluid through the cap. Each of the elements are provided with a flow interface in the region where the elements are joined. The flow interface defines an inlet for the passage of fluid into the passageway of one of the elements, and an outlet for the passage of fluid from the passageway out of the same element.

A heat exchanger, and method of manufacture of a heat exchanger configured to be placed into contact with an object to regulate the temperature of the object. The heat exchanger comprises a layer of material defining a passage through which a heat transfer fluid may flow. The material layer has a first side for contact with the object; and a second side which, in use, will face away from the object. The first side has a relatively high coefficient of thermal conduction. The second side has a relatively low coefficient of thermal conduction compared to the first side.

A temperature regulation system for regulating the temperature of a portion of a body, in particular of a user's body.

The system comprises one humidity sensor for measuring humidity in the vicinity of the portion of a body, one temperature adjustment element for providing heat to a portion of the body, a memory unit for storing one threshold humidity related value (H.sub.thresh) and one reference user information related values (t.sub.ref, θ.sub.ref), a controlling unit in communication with the humidity sensor, with the memory unit and with the temperature adjustment element, and configured to determine one instant user information related value (t.sub.inst, θ.sub.inst), perform a comparison between one instant user information related value (tin.sub.ct, θ.sub.inst) and one triggering user information related value (t.sub.trig, θ.sub.trig) based on said reference user information related value (t.sub.ref, θ.sub.ref), activate the temperature adjustment element to provide heat to a portion of the body depending on the result of said comparison.
