An allergy involves an exaggerated response of the immune system to a harmless substance. One of the common forms of allergies is seasonal allergic rhinitis or hay fever which affects many individuals all over the world with symptoms similar to the common cold.
Seasonal allergy can be caused by the airborne pollen from grasses, trees and flowers. Exposure to pollen instigates an immune response which leads to inflammation of the blood vessels in the air passages and generates various symptoms that can be annoying but rarely life-threatening.
What are the eye issues?
The symptoms of seasonal allergy usually affect the eyes. The abundance of blood vessels in and around the eyes can end up irritated and inflamed. In most cases of seasonal allergies, a reaction starts with itchy and watery eyes.
As the irritation persists, the individual will scratch or rub the eyes in an attempt to minimize the symptoms that can worsen them and cause them to turn red. The conjunctiva which is a membrane that lines the eye can become irritated which causes conjunctivitis. Several over-the-counter and prescription medications can be used to alleviate the eye issues linked with seasonal allergy.
An allergic reaction often causes nasal congestion and runny nose since the airways are inflamed and filled with mucus. Part of the immune response that occurs once the body is exposed to an allergen is the production of mucus.
The mucus accumulates in the sinuses and drains into the throat which causes various symptoms. The congestion can also trigger coughing, headaches, sneezing and wheezing. Those who have seasonal allergy will notice impairment of their sense of smell due to the buildup of congestion.
It is also possible for digestive symptoms to occur if an individual has seasonal allergy. Some individuals experience abdominal discomfort, stomach cramps and even episodes of vomiting.
Hay fever is known to cause sleep disturbance as one of the symptoms. This is likely due to the manifestation of other symptoms such as runny nose, coughing, sneezing, headache and congestion that makes it hard for the individual to get quality sleep at night.
Is fatigue a symptom of seasonal allergy?
Among those who suffer from seasonal allergies, the symptoms not linked with the condition can become an annoyance. These symptoms include irritability, fatigue, depression and mood swings.
Based on studies conducted, the reactions can trigger feelings of depression and even fatigue by releasing cytokines. Take note that the cytokines are chemicals that trigger inflammation as a way to protect the body from potential allergens, but once they react with other brain chemicals, it causes the erratic feelings experienced by the individual.
