What Causes Seasonal Allergies?

If you find your allergies are triggered at certain times of the year, they could be seasonal allergies. Here’s what you need to know about triggers throughout the year, so you can properly treat nasal congestion and enjoy the season.


Whilst most people are thinking of warmer weather, longer days and beautiful blooms, if you’re a hayfever sufferer we don’t blame you for being less than excited. While the blossoms make for a great photo, 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. 


Frolicking through green fields might be your idea of a summers 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. 


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


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.
