Allergic shiner

Allergic Shiner

Allergic shiner (pronunciation: /əˈlɜːr.dʒɪk ˈʃaɪnər/) is a term used to describe the appearance of dark circles under the eyes, which are similar to a "black eye" or shiner, caused by allergic reactions.

Etymology

The term "allergic shiner" is derived from the word "allergy", which comes from the Greek words allos meaning "other" and ergon meaning "work". The term "shiner" is a colloquial term for a black eye, which is often dark and shiny, hence the name.

Definition

Allergic shiners are dark circles under the eyes caused by congestion of the nasal and sinus cavities. This congestion leads to poor venous return, which is the process of blood flowing back to the heart. This results in the pooling of blood and the dilation of the small vessels under the eyes, causing a darkened appearance.

Symptoms

Symptoms of allergic shiners include dark circles under the eyes, puffiness, and a tired appearance. They are often accompanied by other allergy symptoms such as sneezing, itching, watery eyes, and a runny or stuffy nose.

Causes

Allergic shiners are caused by allergies, which can be triggered by a variety of allergens such as dust mites, pet dander, pollen, and certain foods. When an individual with allergies is exposed to these allergens, their body releases histamine, a chemical that causes allergy symptoms.

Treatment

Treatment for allergic shiners involves managing the underlying allergies. This can be done through avoidance of allergens, use of antihistamines, nasal sprays, and allergy shots. In some cases, a doctor may recommend immunotherapy, a treatment that helps the body build resistance to allergens.
