What should you know about constant cold hands and feet?

Blood vessels normally narrow in cold conditions, making fingers and toes feel cooler. Persistent symptoms can occur with anaemia or iron deficiency anaemia, particularly when tiredness, breathlessness, paleness, dizziness, or headaches are also present. Hypothyroidism may cause cold sensitivity with low energy, dry skin, constipation, or changes in weight. Reduced blood flow from peripheral arterial disease is more concerning when one foot is colder, walking causes leg pain, or there are slow-healing sores. Colour changes, numbness, tingling, or pain provide useful clues, but the symptom alone cannot identify a cause.

Keep your hands and feet warm with layers, dry socks, and comfortable footwear, and avoid direct heat that could burn numb skin. Do not smoke, as smoking can narrow blood vessels. Note whether both sides are affected, how long warming takes, and whether activity brings leg pain. Arrange a GP review if the problem persists, is new, or comes with fatigue, breathlessness, skin changes, numbness, or reduced exercise tolerance. Blood tests and circulation checks may help clarify the cause; do not start iron supplementation without advice.

Seek urgent care if a hand, foot, finger, or toe suddenly becomes cold, pale, blue, very painful, numb, or difficult to move. Prompt assessment is also needed for a new sore that does not heal, severe swelling, or rapidly changing skin colour. Chest pain, severe breathlessness, fainting, or sudden weakness require emergency help regardless of temperature in the limbs.

Ask whether you need tests for anaemia or thyroid function, whether pulses and circulation should be checked, whether iron treatment is appropriate, and which colour or pain changes require same-day care.
