Hay fever sufferers are being warned of high pollen levels across the country today and tomorrow.
Met Éireann says there are high levels of tree pollen at present, but there's a reduced risk on eastern coasts.
Most people with hay fever will have mild symptoms like sneezing, a runny nose, and itchy eyes.
However, around 300,000 people have both hay fever and asthma, which can lead to more severe problems.
Ruth Morrow, respiratory nurse specialist with the Asthma Society of Ireland, says there are ways of managing hay fever:
'Wear a pair of wrap around sunglasses that will block the pollen from getting into your eyes.
Splash your eyes with some cold water, it'll cool down that eye irritation.
Take your antihistamines, there are a lot of antihistamines that are available over the counter in your local pharmacy.
When you're out for your exercise or your daily walk, maybe go when the pollen count tends to be a little bit lower.
They tend to be that little bit lower in the morning time, so I would advise go out in the morning time instead of the evening time.'
