What is the difference between seasonal and perennial allergies in the context of Needle Grass pollen?

Seasonal and perennial allergies are both responses of the immune system to allergens, but they differ primarily in their timing and duration.

Seasonal allergies, also known as hay fever, occur during specific times of the year, usually when certain trees, grasses, and weeds release their pollen into the air. If you have a seasonal allergy to Needle Grass pollen, you'll likely experience allergic symptoms only during the period when this grass is actively pollinating, which typically occurs in late spring and early summer. Symptoms may include sneezing, runny nose, itchy eyes, and congestion.

On the other hand, perennial allergies are year-round allergies. They're usually triggered by exposure to allergens that are present throughout the year, such as dust mites, pet dander, and mold spores. If you were to have a perennial allergy to Needle Grass pollen, it would imply that you're exposed to this type of pollen constantly, no matter the season. This might be possible if, for example, you live in a region where Needle Grass blooms all year or you frequently handle this grass as part of your job or hobby.

It's important to note that the symptoms of seasonal and perennial allergies are largely similar. However, perennial allergies could lead to chronic symptoms such as long-term nasal congestion or recurrent sinusitis.

In both cases, treatment usually involves avoiding the allergen as much as possible and taking medications to manage symptoms. Over-the-counter antihistamines, decongestants, and nasal steroid sprays are common options. For more severe allergies, prescription medication, allergy shots or under-the-tongue immunotherapy might be recommended. Always speak with a healthcare provider to choose the right course of action.
