Warmer temperatures, longer days, and blooming foliage can bring seasonal allergies. According to the Asthma and Allergy Foundation of America, more than 100 million Americans experience various types of allergies each year. In fact, according to this source, approximately 81 million people in the United States were diagnosed with seasonal allergic rhinitis (hay fever) in 2021.  According to the Centers for Disease Control and Prevention (CDC), climate change may also impact pollen levels, which in turn can affect our health. According to the Asthma and Allergy Foundation of America, several cities in Texas, including Dallas, Houston, and San Antonio, consistently rank among the top 25 worst cities for allergies in the United States.

Individuals who experience allergy symptoms only during certain times of the year may be suffering from seasonal allergies. According to the Asthma and Allergy Foundation of America, seasonal allergic rhinitis is an allergic reaction to pollen from trees, grasses, and weeds, occurring in spring, summer, and fall when pollen is in the air. The type of seasonal pollen allergen can vary in terms of timing and severity depending on the region in which individuals live.
