The primary cause of cold hands is cold weather, which impairs peripheral nerve circulation; this condition is also directly linked to a weakened immune system. Insufficient blood supply can also lead to persistently cold hands. During winter, capillaries typically constrict (not dilate), and lack of physical activity may exacerbate symptoms of cold hands. It is essential to increase physical activity and take appropriate measures to keep the body warm.
