Burning ears are relatively common and are generally associated with increased blood flow after exercise, rapid temperature changes, and mental stress. However, inflammation or allergies in the ears need to be ruled out as well. I. Physiological factors: 1. After strenuous exercise: Exercise will cause an accelerated heartbeat, the body’s blood circulation will speed up, and more blood will be supplied to the limb muscles. After exercise, the blood in the limbs will flow back to the heart, and when it flows through the ears, a feeling of heat will appear, which can be automatically recovered after rest; 2. Large temperature difference: When entering a warm room from a cold outdoor area, the blood vessels in the ears will expand under the high indoor temperature, resulting in Ear heating; 3. Mental tension: When you are shy or arguing with others, your brain nerves will be overly hyperactive or tense, resulting in dilated ear blood vessels, rapid heartbeat, and hot ears. Pathological factors: 1. Inflammation of the ear: When suffering from otitis externa or otitis media, this can lead to local inflammation of the skin such as redness, swelling, heat and pain, and the phenomenon of burning; 2. Allergies: After the skin of the ear is stimulated by external allergens, this can lead to itching, redness, swelling and fever in the ear.
