How is cold intolerance treated?

Cold intolerance is treated by identifying its cause and addressing it, while using practical measures to keep your body warm. A clinician may ask when the symptom began, whether it affects your whole body or hands and feet, and whether you have tiredness, pale skin, weight changes or changes in your bowel habits. Assessment may include an examination and blood tests. Treatment is not one-size-fits-all: replacing a nutrient, treating anaemia or managing an underactive thyroid may help when one of these is responsible.

Feeling cold all the time can occur when the body has fewer red blood cells or less iron available for healthy red blood cell production. It can also occur with hypothyroidism, when reduced thyroid activity slows processes that help regulate energy and body temperature. Other explanations include low body weight, circulation problems, some medicines or exposure to a cold environment. The same symptom can have different causes, so taking iron or thyroid medicine without an assessment may be unhelpful or unsafe.

If tests show iron deficiency, treatment may involve an iron supplement and attention to why the deficiency developed. Anaemia is managed according to its type and cause. If an underactive thyroid is confirmed, a clinician may prescribe thyroid hormone replacement and monitor the response with follow-up tests.

Arrange a primary-care appointment if cold intolerance is persistent, new or becoming more noticeable. Keep a brief record of when you feel cold, the areas affected, medicines you take and other symptoms. Dress in layers, keep your home comfortably warm, protect your hands and feet, and eat regular balanced meals if you can. Avoid direct heat on numb skin because reduced sensation can make burns harder to notice. Do not start supplements or borrow prescription medicine before a clinician has checked the likely cause.

Seek urgent medical help if feeling cold comes with confusion, unusual drowsiness, trouble breathing, chest pain, fainting, severe weakness or blue or grey lips. These symptoms can signal a problem needing prompt assessment rather than routine treatment. Contact a clinician promptly for new swelling, marked paleness, rapid heartbeat, unexplained weight change, heavy bleeding or symptoms that are steadily worsening.

You could ask: Which causes of cold intolerance fit my symptoms? Do I need blood tests for anaemia, iron deficiency or thyroid function? Could any of my medicines contribute? If treatment is started, when should we review my symptoms and test results?
