Does wearing a mask or having a cloth over your nose and mouth help with hayfever?

You may find that wearing a mask is helpful when doing specific activities like gardening where your body is exposed to high levels of pollen. It is quite hard to avoid pollen altogether, though, and it can still land on the skin or irritate the eyes even if you are wearing a mask.

My advice would be to wear sunglasses when you are out and to change your clothing when you get home. This way pollen will be less likely to be distributed around the home and your eyes will have some protection. You could also try a hayfever remedy like Pollinosan Hayfever Tablets to keep symptoms under control.
