Detailed explanation-1: -That’s because of vasodilation of the blood vessels right under the surface of your skin (called capillaries), which increases blood flow to your face. Step into a hot tub: When you enter the hot water, your body automatically tells capillaries to dilate. This is to help your body heat up more slowly.
Detailed explanation-2: -Vasoconstriction is a response to being too cold. The process involves the narrowing of blood vessels at the skin surface to reduce heat loss through the surface of the skin. Vasodilation is a response to being too hot.
Detailed explanation-3: -Vasodilation refers to the widening of the arteries and large blood vessels. It is a natural process that occurs in response to low oxygen levels or increases in body temperature. It increases blood flow and oxygen delivery to areas of the body that require it most.
