4 Common Types of Seasonal Allergies

Updated: Dec 10, 2021

Pollen is the leading cause of seasonal allergies in the US. Plants, trees, and flowers use pollen to create other plants of the same species. While pollen is beneficial for plant species, it can trigger allergies in humans.

We list some other common types of seasonal allergies in this post and how to stay safe from them.


Like other allergies, pollen allergies manifest as sneezing, watery eyes, and a runny nose. Pollen allergies are divided into many kinds.

1- Birch Pollen Allergy

As the name suggests, this allergy is caused by birch trees. It usually happens in the spring season when the birch trees start to bloom. During the blooming season, many tiny pollen grains are spread through the wind. Do you know that a single birch tree can produce around 5 million pollen grains during the blooming season? Through the wind, these pollens are spread to distances as far as 100 yards from the producing birch tree.

2- Oak Pollen Allergy

Like birch trees, oak trees also start blooming in the spring season. However, oak pollen is less allergic than other pollens and results in less frequent and less intense allergic reactions. But, oak pollen stays in the air for a longer time than other kinds of pollens. These characteristics of oak pollens still make them a danger to some people that are extremely sensitive to oak pollen.
