What causes cold intolerance?

The body balances heat production and heat loss through blood flow, metabolism, movement, and hormone signals. Anaemia, particularly Iron Deficiency Anaemia, may accompany tiredness, breathlessness on exertion, pale skin, or headaches. Hypothyroidism can slow body processes and may also cause constipation, dry skin, weight change, or a slower pulse. Poor nutrition, low body weight, some medicines, and prolonged exposure to cold can contribute. Cold Intolerance by itself cannot identify one condition; the timing and accompanying symptoms guide assessment.

Keep your living space comfortably warm, wear layers, eat regular nourishing meals, and notice whether coldness is new, constant, or limited to your hands and feet. Make an appointment if the symptom persists or is paired with fatigue, breathlessness, changes in weight, constipation, heavy menstrual bleeding, or changes in skin and hair. A clinician may check your history, pulse, skin, blood count, and thyroid function before suggesting treatment. Thyroid Hormone Replacement is used only when thyroid underactivity has been diagnosed.

Seek urgent help for confusion, severe drowsiness, slurred speech, uncontrolled shivering, fainting, chest pain, or breathing difficulty after cold exposure. These signs can indicate dangerous cooling or another acute problem and need prompt assessment.

Ask whether blood tests for anaemia or thyroid function are suitable, whether bleeding or nutrition could be relevant, and which symptoms should prompt earlier review.
