Thermal sensations can be detected and communicated from localised sensory regions of the skin.[6] Skin acts as both a medium and means for delivering mechanisms of thermoregulation, including insulation, sweating and control of blood flow.[7] Skin tissue itself is subject to a maintaining function within a range of tissue temperatures (skin temperature), which are the result of several factors including heat loss from subcutaneous tissues via radiation, conduction and vaporisation of water.[2]
