wiki too says -->
  • Yes. Capillaries do constrict known as vaso constriction. This is when the body gets cold therefore the capillaries constrict so that no heat is lost through the skin. Capillaries also dilate, this is when the body is too warm. They dilate which means the blood comes to the surface and heat is lost by diffusion through the skin and into the atmosphere.

Capillaries vasoconstrict under "special" circumstances such as an adrenaline rush (eg. fear) or if you have internal bleeding. This is so that blood can be sent to our vital organs, like our brain and heart. Our body is very happy to sacrifice the skin of our nose, fingers etc (like during frostbite) to keep our vital organs alive.
