The reason for this may be the General state of health, says the doctor. People with cold hands can have Raynaud’s phenomenon. It is characterized by the blood vessels overreact to cold or emotional stress.

Accordingly, the fingers become icy, wrinkled look and turn pale or blush.

Raynaud’s phenomenon is little known, and its symptoms can seem minor, so people with them rarely go to the doctor.

Sometimes the phenomenon occurs as a result of Smoking, injury of the hands or feet, disease related to the arteries or carpal tunnel syndrome — a pathological condition that occurs due to compression of the median nerve in the wrist canal and cause pain, numbness and tingling in the fingers.
