An allergen is a material that is otherwise harmless and induces an allergic reaction. An allergic reaction to particular allergens is allergic rhinitis, or hay fever. In the case of seasonal allergic rhinitis, pollen is the most common allergen. These are signs of allergies that arise with the change of seasons.
According to the American Academy of Allergy, Asthma & Immunology (AAAAI), nearly 8 percent of adults in the United States experience allergic rhinitis of some kind. Allergic rhinitis can also be present in between 10 and 30 percent of the global population.
Signs & Symptoms
Popular allergic rhinitis symptoms include:
After you come into contact with an allergen, you will usually experience one or more of these symptoms immediately. Some symptoms can only arise after long-term exposure to allergens, such as chronic headaches and fatigue. Fever isn’t a hay fever symptom.
It releases histamine when your body comes into contact with an allergen, which is a natural chemical that protects your body from the allergen. This chemical, including a runny nose, sneezing, and itchy eyes, can cause allergic rhinitis and its symptoms.
Other common allergens, besides tree pollen, include:
Pollen can be particularly troublesome at certain times of the year. In the season, tree and flower pollen is more prevalent. In the summer and fall, grass and weeds produce more pollen.
An allergic reaction to pollen is involved in hay fever.
Trees, grass, and ragweed are plants that cause hay fever. By the wind, their pollen is carried. (Insects bear flower pollen and do not cause hay fever.) The types of plants that cause hay fever differ from person to person and from region to region.
The amount of pollen in the air will influence whether or not the symptoms of hay fever develop.
It is more likely that hot dry, windy days have a lot of pollen in the air.
Most of the pollen is washed down to the ground on cold, humid, rainy days.
In households, hay fever and allergies also occur. You are likely to have hay fever and allergies if both of your parents have hay fever or other allergies.
How to diagnose allergic rhinitis?
You would possibly just need a physical exam if you have mild allergies. However in order to find out the best treatment and prevention plan for you, your doctor can conduct certain tests.
One of the most frequent ones is a skin prick test. To see how the body responds to each of them, your doctor puts many chemicals on your skin. Usually, if you’re allergic to a product, a tiny red bump emerges.
Also popular is a blood test, or RAST (radioallergosorbent test). The RAST tests the amount of antibodies to various allergens in your blood with immunoglobulin E.
Managing your allergies is the best way to avoid allergy symptoms before your body has a chance to react adversely to substances. For the specific allergens to which you are susceptible, take the following preventive measures:
Before seasonal allergy attacks, the AAAAI advises starting drugs. If you’re susceptible to tree pollen in the spring,
