Question
My 5-year-old occasionally experiences red and hot ears, but it’s not a frequent occurrence. What has been the treatment and its effectiveness in the past? I want to know what causes red and hot ears and how they are triggered, as well as whether they are harmful to the body.
Answer
Red and hot ears may be caused by the thin skin on the head, face, and ears, which contain a rich network of blood vessels. When a large amount of blood flows through the ears, the vessels dilate and become thicker, leading to redness. Since blood has a certain temperature, the ears also feel hot. Additionally, when exposed to lower outdoor temperatures, the vessels constrict, causing the face to appear pale. If you step out from a warmer indoor environment into cooler air, the vessels suddenly dilate, making the ears feel hot.
