Skin temperature refers to the temperature of the outermost surface of the body. Normal human skin temperature on the trunk of the body varies between 33.5 and 36.9 C (92.3 and 98.4F), though the skin's temperature is lower over protruding parts, like the nose, and higher over muscles and active organs.[1] Recording skin temperature presents extensive difficulties and whilst not a clear reflector of internal body temperature, skin temperature nevertheless holds significance in assessing the healthy function of skin.[2] Historically, the physiological significance of skin temperature has been overlooked as clinical analysis has favoured measuring temperatures of the mouth, axilla and/or rectum.
