Your body’s immune system ideally fights against “bad guys” like flu viruses, colds, and other infection-causing organisms that seek to make you sick. But sometimes, your immune system reacts to things that really aren’t all that harmful to you. This is the case with seasonal allergies. Seasonal allergies occur when your body reacts to allergens that tend to show up in a certain season. Seasonal allergies are usually your body’s reaction to pollen. Pollen is a powdery substance that forms the male sperms cells that fertilize plants so they can reproduce. Common culprits of seasonal allergies include:
Depending on where you live, spring allergies can pop up around February and end in early summer. Fall allergies can take place in late summer and continue until late fall. Pregnancy can make seasonal allergies worse. Also, a condition called “rhinitis of pregnancy” can cause similar symptoms to seasonal allergies. This usually occurs in the last trimester. But the cause of rhinitis of pregnancy is extra hormones, not allergens.
