Yes, if you are allergic to it. There all sorts of pollen and the main ones that cause hayfever are grass tree and weed pollens. Mould spores also trigger allergies. It all depends on your sensitivity level or trigger point.

If you have a high trigger point then you might only get a reaction on the worst of the pollen days - or maybe you won't react at all because you never reach your trigger level. So reducing the amount of allergen in your immediate vicinity will help with hayfever. That's why people use pollen blockers and pollen barriers on their nose, and it's also why air purifiers in the home can be helpful.
