A cold room and poor circulation are the most common causes of cold feet. Though the sensation is uncomfortable, soaking in a warm bath or putting on thick socks often relieves this temporary issue. People who experience cold feet on a regular basis, however, should talk to a doctor, as the problem could be symptomatic of a larger issue that requires medical intervention.
Raynaud's syndrome, also called Raynaud's phenomena or disease, has various causes, including inflammatory, nerve-related, and autoimmune responses. Injury to the hands or feet, certain medications, smoking, and repetitive use of the feet or hands can trigger the characteristic signs and symptoms of this condition. Some people with Raynaud's syndrome have no known underlying cause or risk factors. With Raynaud syndrome, the skin on the toes or fingers turns blue, purple, or white due to a lack of blood. This constriction makes the extremities overly sensitive to temperature changes. Raynaud's is more common in women and people over 30, particularly those with a family history of the syndrome and individuals living in colder climates.
