Hay fever, also known as allergic rhinitis, is a common allergic condition that causes symptoms such as sneezing, a runny nose, and itchy, watery eyes. It occurs when the body’s immune system reacts to certain allergens, such as pollen, dust mites, or animal dander.
Pollen is one of the most common allergens that cause hay fever. Trees, grasses, and weeds release pollen into the air to fertilize other plants of the same species. When these tiny pollen particles are inhaled, they can trigger an allergic reaction in some people. The severity and duration of hay fever symptoms can vary depending on the type of pollen to which a person is allergic and the amount of pollen in the air.
Dust mites and animal dander are other common allergens that can cause hay fever. Dust mites are tiny bugs that live in house dust and can cause symptoms such as sneezing and a runny nose. Animal dander, which is made up of tiny flakes of skin from pets, can also cause hay fever symptoms.
Symptoms of hay fever can occur at any time of the year, but they are most common during the spring, summer, and fall when pollen levels are highest. Other symptoms of hay fever can include:
- Nasal congestion
- Sinus pressure
- Coughing
- Fatigue
- Headaches
- Itchy throat, nose, and ears
Hay fever can be diagnosed by a doctor through a physical exam, or through skin or blood tests that detect the presence of specific allergens. In many cases, avoiding exposure to allergens and managing symptoms with over-the-counter or prescription medications can effectively treat hay fever.
It is worth mentioning that even if Hay fever is a common and benign condition, it can also affect daily life quality and lead to chronic fatigue and sleep disturbance. In some cases, hay fever can also lead to more serious conditions such as sinusitis or asthma, so it’s important to see a doctor if symptoms persist or become severe.
