Lewis' Hunting Response
Typical response to immersion of the hand in cold water. Skin temp drops significantly in order to conserve heat (to avoid loss of heat through the skin) and then the temperature of the hand fluctuates a few degrees thereafter during exposure. This is caused by fluctuations in blood flow because of the sudden opening of arteries and veins that were previously being constricted to conserve heat.
