Why a white person his skin turns red after a hot bath?
Muscles pull the blood vessels of the body, primarily the systemic arteries which carry red (oxygenated) blood, closer to the surface of the skin where it can easily show through if the skin has little pigment. A person with darker pigments does not show the red blood so clearly. This occurs after a hot bath for rapid heat exchange, since the hot water has heated up the internal environment and the body can cool down faster. The opposite also happens on a cold day, when a person comes in and his skin turns red so that the blood vessels can absorb heat at a more efficient rate.
