The tree pollen season is now in decline with mainly low amounts of oak pollen. The main grass pollen season is a couple of weeks away, expected to start in early June in the south-east of Ireland so now is the time to start taking your medication so that you avoid that first hay fever attack. Low amounts of early-flowering grasses are airborne in good weather, triggering sneezes in some people.

Top Tips to Survive Hay Fever Season

  • Talk to doctor or pharmacist NOW about taking medication to prevent / reduce symptoms. Don't wait until you feel unwell.​
  • Keep an eye on our pollen tracker
  • Stay indoors as much as possible on high pollen days
  • Stay away from grassy areas, especially freshly cut places
  • Keep windows and doors closed when the pollen count is high
  • Put Vaseline around your nostrils to trap pollen
  • Wear wraparound sunglasses to stop pollen getting into your eyes
  • Shower, wash your hair and change your clothes if you have been outside for an extended period
  • Avoid drying clothes outdoors​​​
  • Minimise your contact with pets that have been outdoors and are likely to be carrying pollen
  • Consider a purifier with a built-in air quality sensor to remove allergens and pollutants from the air

When you have an allergy your body reacts when you come in contact with a particular allergen or trigger.  In hay fever/rhinitis when one of these allergens is breathed in, there is an immune response in the lining of the nose. This causes the nasal passages to become swollen and inflamed. 

  • Symptoms occurring mainly in spring and summer are usually triggered by pollen from grasses, weeds and trees.  This is called seasonal rhinitis, and is commonly known as hay fever.
  • When problems occur all year, this is called perennial rhinitis, and they are usually triggered by house dust mite, animal dander or mould spores.

Hay fever is very common in Ireland and up to 80% of people who have asthma also have this condition.

Both asthma and allergic rhinitis are caused by an allergic reaction and are related conditions linked by a common airway. Many of the same allergens are known to trigger asthma and allergic rhinitis.

  • If allergic rhinitis is treated effectively it could reduce asthma symptoms and may even help prevent the development of asthma.
  • If you have asthma hay fever can make your symptoms worse, so the most important step you can take ahead of the pollen season is to make sure your asthma is under control.  If you don't already have an Asthma Action Plan to help you manage your asthma then get one today.

There is currently no cure for either hay fever or asthma, but in most cases symptoms can be controlled.

Some treatments require a prescription from a doctor but others can be purchased over the counter.  Speak to your community pharmacist who can advise on the best non prescription treatment for you. 

Start treatment early if you can.  To help you to do this, identify when your symptoms start and what time of year is worst for you.   This can help you determine what is triggering it, as different pollens and spores are active at different times of the year.
