Human skin has a certain color, due to race, genetic characteristics, lifestyle, hormonal background. Color change is more often associated with exposure to sunlight, and can also be caused by liver pathology, hypervitaminosis. Moreover, this change can affect both the entire skin integument, and be noted in a limited area. More often, there are transient changes that depend on physiological or pathological processes in the body.
The most common symptom of skin changes is redness. Usually this factor is due to physiological processes. The entire length of the skin is permeated with a network of large and small vessels. Filling them with blood or spasm causes this or that discoloration. The narrowing of the superficial capillaries is accompanied by pale skin, blood filling leads to redness.
Physiological causes
The most common reason for the blanching of the skin is hypothermia. Exposed areas of the skin, face, hands, ears, quickly turn pale when exposed to low temperatures. At the same time, it becomes obvious why the ears and face redden when exposed to the sun.
The factor that can cause spasm or blood filling is the release of adrenaline, which has a direct effect on the vessels. In this case, the impact on large vessels leads to spasm and increased blood pressure. Redistribution of blood in the body is accompanied by the expansion of small vessels and, as a result, reddening of the skin.
Strong emotions such as fear, joy, anger are accompanied by the release of hormones, which, in turn, affect the production of adrenaline. That is why, when patients are excited, their ears turn red and burn violently. In this case, the process can spread to the skin of the neck, décolleté. Often, this symptom is accompanied by moisture in the skin and increased sweating. The presence of these additional signs should be taken into account when diagnosing such a condition.
This state does not last long. After a certain time, when the action of the emotional factor stops, or compensatory mechanisms come into play, the color of the skin returns to normal.
With pronounced clinical manifestations, it is possible to use sedatives.
Depending on the influencing factor, redness can affect the entire body, or be characterized exclusively by the fact that the ears turn red. However, some patients note that only one ear may be reddened. Most often, unilateral damage is characteristic of motor or mental activity, when only certain parts of the brain are required to perform a certain work.
Why is the left ear burning or the right one? It all depends on which half of the brain was more involved. If the left ear burns in the evening, most likely, the right side of the brain was more actively involved during the day. However, this theory has not been supported by any serious scientific work. This conclusion is based only on the conclusions of some specialists. The development of this symptom as a result of physical activity is not accompanied by additional signs. Rest, change of activity helps to improve the patient's condition in a short time.
Pathological conditions
The most common reasons why human ears turn red are the following pathological conditions:
- exposure to high temperatures;
- excessive physical activity;
- a bite of an insect;
- exposure to alcohol and other chemical compounds;
- increased blood pressure;
- traumatic injury;
- allergy;
- otitis externa.
Otitis externa
With a unilateral lesion, a red ear may indicate the development of an inflammatory process, both local and diffuse.
This process is localized within the outer ear. In addition to hyperemia, the presence of pain or itching, swelling is also characteristic. If the inflammation is local in nature and is manifested by a boil, then the pain can be very intense, aching, twitching. Typically a local increase in temperature in the lesion, patients complain that it burns inside the ear. With a sufficient spread of the process, the development of subfebrile condition is characteristic.
The diffuse nature of inflammation of the external ear can be caused by trauma to the skin of the external auditory canal or auricle. Quite often, this is noted when the ear toilet is carelessly held. Untimely treatment of the wound surface with antiseptic agents creates conditions for the attachment of an infectious agent.
Traumatic and toxic injury
The toxic effect of some medicines and alcohol on the walls of blood vessels is also accompanied by blood filling of the capillaries and redness of the face. First of all, the vessels of the tip of the nose and earlobes react, with constant abuse, there is constant redness and swelling of the face.
Traumatic injury leads to disruption of the blood supply to the affected organ, the development of edema and pain in it. Symptoms build up over several hours. With a traumatic brain injury or a similar lesion of the ear, there may be heat in the ears, pronounced edema, intense redness of the ear. The improvement of this condition is facilitated by applying cold to the site of injury. To clarify the reason why the ear turns red in this case is not a difficult task.
Allergies and insect bites
It is not difficult to diagnose a condition associated with an insect bite. In cases where the process of injury to the skin remained invisible, there is a bite site. The process is characterized by a one-sided lesion. There may be severe swelling, itching, quite often - intense pain.

Depending on the degree of damage, the process may involve not only the earlobes, where the earrings were pierced, but also the entire auricle. Patients complain that the ear is on fire. There may be itching, swelling of it. In severe cases, an additional symptom is a deterioration in the general condition, the appearance of severe weakness, and a decrease in pressure.
