Seasonal allergies, also known as hay fever or allergic rhinitis, affect millions of people across the United States every year. From spring pollen to fall ragweed, seasonal allergies can significantly impact daily life, productivity, and overall health. Sneezing, runny nose, itchy eyes, and congestion are common symptoms that worsen during specific times of the year.

This comprehensive guide by Ivermectinkart covers everything you need to know about seasonal allergies in the USA.

Tree pollen (Spring)
Grass pollen (Late spring to summer)
Weed pollen / Ragweed (Late summer to fall)
Mold spores (Spring through fall, especially in humid regions)

Pollen from trees, grasses, and weeds is the leading cause of seasonal allergies in the USA.
Climate and Weather Changes
Warmer temperatures and longer pollen seasons have increased allergy prevalence.
Genetics
A family history of allergies increases your risk.
Weakened Immune Response
An overactive immune system mistakenly identifies harmless allergens as threats.
