Why are my ears cold all the time?

* Low body temperature. The most common cause of cold ears is low body temperature, which can occur when you're exposed to cold weather, or when you're sick or taking certain medications.

* Anemia. Anemia is a condition that occurs when you have low levels of iron in your blood. Iron is essential for producing red blood cells, which carry oxygen throughout your body. When you're anemic, your body doesn't have enough red blood cells to carry oxygen to your extremities, including your ears.

* Raynaud's disease. Raynaud's disease is a condition that affects your blood vessels. It causes your blood vessels to narrow in response to cold temperatures, which can lead to cold fingers, toes, and ears.

* Hypothyroidism. Hypothyroidism is a condition that occurs when your thyroid gland doesn't produce enough thyroid hormone. Thyroid hormone helps regulate your body's metabolism, and when you're hypothyroid, your metabolism can slow down. This can lead to cold ears, as well as other symptoms such as fatigue, weight gain, and constipation.

* Diabetes. Diabetes is a condition that occurs when your blood sugar levels are high. High blood sugar levels can damage your blood vessels and nerves, which can lead to cold ears.

* Certain medications. Certain medications, such as beta-blockers and chemotherapy drugs, can cause cold ears as a side effect.

If you're experiencing cold ears that are accompanied by other symptoms, such as fatigue, weight gain, or constipation, it's important to see a doctor to determine the cause.
