摘要：
Embodiments include cooling articles including a receptacle, an endothermic ingredient contained in a first capsule within the receptacle, an endothermic matrix within the receptacle, and a color indicator. The endothermic ingredient, when mixed with the endothermic matrix, generates an endothermic reaction, and the color indicator is activated upon the generation of the endothermic reaction to indicate that cooling has been initiated. Other embodiments include cooling articles including an electric circuit configured to melt at least a portion of the first capsule to enable the endothermic ingredient and the endothermic matrix to mix. Systems for providing cooling that include a person support apparatus and a cooling article including a thermoelectric device coupled to the person support apparatus to direct heat from a source region to a sink region including the person support apparatus are also described.
