Why do people suffer from hypothermia look pale?

People suffering from hypothermia often appear pale due to the body's response to extreme cold. As the body temperature drops, blood vessels constrict to conserve heat, reducing blood flow to the skin and extremities. This vasoconstriction results in a lack of oxygenated blood reaching the surface, leading to a pale appearance. Additionally, less blood flow means the skin loses its normal color, further contributing to the pallor.
