It turns white when it is hot. Is it warm and white skin?

When the weather is hot, because the skin temperature is lower than the outside temperature, a lot of heat will accumulate inside the skin, which will lead to particularly active blood circulation. Blood will easily penetrate into the skin surface through tiny blood vessels on the skin surface. At this time, the metabolism level of the skin will be enhanced due to the accelerated blood circulation, and the skin color will become whiter than usual.

Warm white skin tends to be yellow and warm. One of the ways to judge whether you have cold skin or warm skin is to observe the color of veins under the wrist skin in the sun. If blood vessels are mostly green, they are warm-skinned; if blood vessels are mostly blue, they are often cold-skinned.
