Because it contains receptors that are sensitive to blood temperature
But the skin also contains temperature receptors that send electrical impulses to this part of the brain

Q

Vasoconstriction

A

Capillaries constrict and become more narrow
So less blood runs through
Therefore less what from the blood is transferred from the skin surface

Skeletal muscles begin contracting
Which requires energy so the muscle cells begin respiring more
So heat released
