Why Do Feet Get Cold?

Other than obvious reasons involving temperatures, many people have occasional or persistent cold feet that can make them feel very uncomfortable. Several causes are possible for the individual with this problem.

Sleep

Cold feet at bedtime is a common aggravation, and some people wear socks to bed, especially in winter. This problem occurs because body temperatures drop a bit when people get ready to sleep, resulting in cold extremities.

Peripheral Neuropathy

Impaired circulation to the feet, or peripheral neuropathy, is a relatively common cause of chronic cold feet. This is more likely in elderly people, inactive individuals and in those with diabetes.

Peripheral Vascular Disease

Another circulation issue, peripheral vascular disease, narrows blood vessels and restricts blood flow. This results in high blood pressure along with cold fingers and feet. Unlike peripheral neuropathy, it often affects only one foot.

Atherosclerosis

A person with atherosclerosis may have chronic cold feet. In this condition, fatty material adheres to artery walls, causing high blood pressure and angina.

Anemia

Anemia also can cause cold feet and fingers. In this condition, the individual has a low level of healthy red blood cells, resulting in fatigue and headaches.
