What should you know about hands and feet cold during winter?

In cold air, blood vessels in the hands and feet narrow to conserve heat for the body’s core. They should gradually warm in a comfortable environment. Symptoms that continue indoors, affect one side, cause pain or numbness, or lead to white, blue, or blotchy skin may point to reduced circulation. Anaemia, iron deficiency anaemia, hypothyroidism, and peripheral arterial disease can also be associated with cold extremities, though symptoms alone cannot identify the cause.

Use insulated socks, gloves, and layers that are warm without restricting movement. Keep the whole body warm, move your fingers and toes regularly, and take breaks from sitting still. Warm cold skin gradually with body warmth or lukewarm water; avoid placing numb hands or feet against a heater. Protect the skin from cracking and record episodes, colour changes, pain, and how long warming takes. Do not take iron unless a clinician recommends it after assessment.

Seek urgent care if a hand or foot suddenly becomes pale, blue, very painful, weak, or numb, or if you also have chest pain, fainting, or severe breathlessness. Make an appointment if coldness persists through warmer settings, repeatedly disrupts daily life, causes sores, or comes with fatigue, dizziness, or walking pain. A clinician can examine pulses and consider blood or thyroid tests.

Is the circulation to my hands and feet normal? Could anaemia or thyroid disease be involved? Do my medicines or smoking affect circulation? What warming method and tests are suitable for me?
