Why do the veins on my arms become less apparent when it is cold? But more apparent when it is hotter or I am doing physical labor?
This is part of your thermoregulation system. When it's hot, your body pumps more blood to veins near the surface in order to radiate heat from it. Likewise, when it's cold, blood is withdrawn from the surface to keep it warm.
The Short Answer
This is part of your thermoregulation system. When it's hot, your body pumps more blood to veins near the surface in order to radiate heat from it. Likewise, when it's cold, blood is withdrawn from the surface to keep it warm.
