What should you know about feet and hands get cold?

Cold hands and feet are commonly a response to the environment, while ongoing or one-sided coldness needs assessment. The symptom can also accompany low iron or anaemia, an underactive thyroid, or reduced circulation. It does not by itself identify a particular condition.

Write down when the coldness starts and whether warming restores normal sensation and colour. Persistent pallor or blue colouring, pins and needles, cramps when walking, skin changes, or unusual fatigue gives a clinician useful context. Iron-deficiency anaemia may cause tiredness and feeling cold; hypothyroidism can cause broader cold intolerance. Peripheral arterial disease more often affects circulation to the legs and may cause exertional discomfort. A symptom diary cannot diagnose the cause, but it can reveal a pattern.

Use layers, warm footwear, and regular gentle movement. Keep the skin dry and inspect toes and fingers if sensation is reduced. Do not smoke, and avoid tight shoes or gloves that restrict movement. Make a routine appointment if the problem persists despite warmth, is getting worse, or affects sleep or walking. Bring a list of medicines and mention heavy periods, dietary restrictions, or previous low blood counts.

Get urgent care for sudden coldness in one limb, intense pain, marked colour change, new weakness, or inability to move the hand or foot. Seek prompt advice for sores, blackened skin, or pain at rest. Chest pain or breathlessness alongside cold, clammy skin needs emergency help.

Ask what causes are most relevant to your history, whether a blood count or thyroid test is appropriate, and how circulation will be checked. If iron deficiency is suspected, ask what is causing it before considering iron supplementation.
