2. Anemia: When the body lacks iron
Anemia is another common factor linked to cold feet. This condition occurs when the body does not have enough healthy red blood cells to carry oxygen. With less oxygen circulating, the feet and hands may feel colder.

Causes of anemia include a lack of iron or vitamin B12 or even chronic diseases.

3. Diabetes: Watch out for neuropathy

Diabetes is a disease that affects the way your body processes blood sugar. When it is not well controlled, excess sugar can damage your nerves, especially in your extremities, such as your feet.

This condition, called diabetic neuropathy, can cause abnormal sensations such as tingling, numbness, or a feeling of intense coldness in the feet.

4. Hypothyroidism: Slow metabolism, cold feet
The thyroid is a small gland in the neck that produces hormones that regulate metabolism. When the thyroid is working less than it should, the entire body slows down, including the body’s ability to maintain its temperature.

If you suspect hypothyroidism, see a doctor. Diagnosis is made through blood tests, and treatment is usually simple, with hormone replacement therapy.

5. Raynaud’s phenomenon: Fingers that change color
Raynaud’s phenomenon is a condition that affects the blood vessels in the hands and feet, causing them to constrict in response to cold or stress. This reduces blood flow, leaving the fingers pale, blue, and, in some cases, even numb.

After the episode, the fingers may become red and painful as the blood returns to the bloodstream. Although not serious, Raynaud’s can be associated with other diseases, such as lupus or rheumatoid arthritis.

Protecting your hands and feet from the cold and avoiding stressful situations helps control symptoms.

6. Multiple sclerosis: An impact on the nerves
Multiple sclerosis is an autoimmune disease that affects the central nervous system, interfering with communication between the brain and the body. One of the symptoms is dysesthesia, or abnormal sensations such as intense heat or cold in the feet and hands.

This type of discomfort occurs because damaged nerves have difficulty transmitting temperature signals.

Treatment varies depending on symptoms and may include medications to relieve discomfort.
