Hlo Buddy!

Answer :  Red ears may be the result of your body flushing or blushing. Flushing also results in warm and burning skin. A main cause of flushing is an emotional reaction, resulting in your blood vessels opening wider in certain areas because of a signal in the nervous system.

Ears can turn red and hot as a result of body's reaction to an internal or external action. During the times of nervous or panic attacks or episodes of stress, the body reacts to it. There is sudden release of chemicals in the body, which results in certain changes in the body.

Normally, in situations of embarrassment, acute fear, anxiety and stress there is release of adrenaline and noradrenaline. This causes a sudden wave like feeling in the body and results in vasodilation. It raises the heart beats, causes rapid pulse and increases the blood supply. This can result in flushing of the parts and is particularly noted on the face. The ears may appear red due to blushing and may feel hot to touch. It is more noticeable in people with a fair skin.

•Ears Turning Red and Hot Caused Due to Exposure to Environment

Ears are naturally exposed to the surroundings and any changes in weather or temperature can easily affect the skin around the ears. Being exposed to the sun for long, during summer or peak hours of heat, can cause reddening of ears, with hot flushing. Similarly, exposure to extreme cold or snow, when ears are not covered, can affect the skin and cause red ears.
