Seasonal Allergies: Causes & Relief
Sneezing, itchy eyes, and a runny nose every spring or fall? Here's what causes seasonal allergies and how they can be managed.
Triggered by pollen and airborne allergens
Tend to follow predictable seasons
Respond well to the right approach
Breathing trouble needs urgent care
Seasonal allergies — often called hay fever — affect a large number of people, usually at predictable times of year. They're not dangerous for most, but they can make daily life genuinely miserable, and they respond well to the right approach.
What causes them
Seasonal allergies happen when your immune system reacts to airborne triggers like pollen from trees, grasses, or weeds. The result is sneezing, a runny or stuffy nose, and itchy, watery eyes. They tend to follow the seasons, which helps distinguish them from a cold.

Reducing exposure to triggers helps — and a range of approaches can ease symptoms. Because what's best depends on your symptoms and history, it's worth a conversation rather than guessing among the many options available.
When to see a doctor
Consider seeing a physician if allergies are interfering with sleep or daily life, aren't improving, or if you're unsure whether it's allergies or something else. Seek urgent care for any difficulty breathing or signs of a severe allergic reaction.
