What are cold hands?
It is normal for your hands to feel cold in cold or freezing weather because warm blood is pumped out from your heart, and your hands are relatively far from your heart.
Persistent cold hands or a feeling of cold hands when the temperature is not cold might be a sign of a circulatory disorder, blood vessel damage due to frostbite, or another disease, disorder or condition that affects your arteries, veins, capillaries, or your metabolism.
