What Causes Seasonal Allergies?

Here’s what you need to know about triggers throughout the year — all of them — so you can properly treat nasal congestion and enjoy the season. 

Seasonal Allergies Tips: Spring


Unless you live at the North Pole, spring usually means beautiful blossoms and blooms galore. While blossoms make for a great photo op, they also make a lot of pollen, especially the ones on trees. In fact, the first pollen of the season to hit the air is from trees, sometimes as early as January in the South.

Seasonal Allergies Tips: Summer


Frolicking through green fields is anyone’s summer dream. While those sunny fields look enticing, remember grass is the main culprit of Summer allergies, and hot, dry days can only make it worse. So, make sure to rinse off and change outfits when coming back inside to get rid of that grass pollen.

Seasonal Allergies Tips: Fall


Along with beautiful foliage, autumn brings its biggest sinus allergy trigger — ragweed and other weed pollen. It’s worst in September and spreads for miles, so you still sneeze even when you’re miles from the woods. Found in wet leaves and soil, mold is another autumn trigger, so think twice before jumping in that leaf pile.

Seasonal Allergies Tips: Winter


Luckily, pollen levels go down during winter. Unfortunately, we spend less time outside during colder months, and more time cozying up indoors. This makes indoor allergies the biggest triggers, like dust mites, and pet dander — nothing a vacuum with a HEPA filter and RHINOCORT® can’t help with.
