Deep dives
Understanding Seasonal Allergens
During spring, tree pollen emerges as the primary allergen affecting many individuals, particularly in regions like New York City. While mold spores can be present, they typically aren't significant until the fall, making pollen the main concern for allergy sufferers at this time. For those sensitive to these allergens, their immune systems overreact, resulting in common symptoms such as sneezing, runny noses, and nasal congestion, as well as impacting the eyes and even triggering asthma or eczema flare-ups. Recognizing these symptoms can help distinguish between allergies and viral infections, as allergic reactions often lack fever or body aches, which accompany infections.
