Pollen Allergy

hay fever sufferer from pollen allergy


Hay fever is a common allergy which affects approx 2 in 10 people in the UK and is caused by an allergy to pollen.  Hay fever is traditionally associated with grass or hay pollens, the most common is grass pollen. Grass pollen normally affects people each year from late spring to early summer.

However, pollen is also produced by other plants, trees and flowers, tree pollen usually affects sufferers in early spring to late spring whilst nettles and docks (weed pollen) pollinate from early spring through until early autumn. As the symptoms of hay fever occur at the same time or in the same season each year, it is also known as season allergic rhinitis.

Symptoms of hay fever (an allergy to pollen):

  • A runny or itchy nose
  • Itchy and watery eyes
  • Itchy throat
  • A block nose
  • Sneezing
  • Headaches
  • Face pain

The above symptoms will vary from person to person, and in some instances, only nasal symptoms can occur whilst other suffers may only be affected by itchy and watery eyes.  Sometimes, the symptoms may be so severe that they affect sleep and interfere with school, studying or work.

Children who are school-age along with teenagers often develop hay fever, and, in many cases, the condition improves or goes away.  Hay fever can run in families and if you suffer from asthma or eczema, you are more likely to develop hay fever (hay fever sufferers are also more likely develop asthma or eczema as well.)

Avoiding pollen – is it possible?

Avoiding pollen is impossible but reducing your exposure can help to alleviate the symptoms. Always check the pollen count, this is measured by the number of pollen grains per cubic metre of air, a high pollen count is above 50. The following may help when the pollen count is high:

  • Keep away from large grassy places, avoid camping and cutting grass
  • When you are out and about wear wrap-round sunglasses
  • After being outdoors shower and wash your hair, especially if you have been in the countryside
  • Keep your windows and doors shut and stay inside as much as you can.

Practical PIV

Staying inside is one thing but when it’s hot outside you may be in need of some air. If opening the window is not a good option you may want to consider another method to keep you and your home ventilated. EnviroVent’s Mr Venty range of condensation control units provide you with continuous fresh, filtered air all year round without having to open a window in summer.

Using a technique called Positive Input Ventilation (PIV), the units gentle ventilate the home from a central position (hallway, landing or loft) to transform a stagnant and stale atmosphere into a fresh and healthy one! What’s more, the Mr Venty loft unit has an added bonus for hay fever sufferers as it is fitted with a G4 filter which filters out large pollen particles.

In addition to this, asthma and allergy sufferers will also benefit from this as the continuous fresh, filtered air from a Mr Venty unit also controls the levels of humidity in the home, keeping it free from condensation and mould (another known allergen); not only will the humidity in the home be controlled, this type of ventilation will also diminish the dust mite population, another known ‘trigger’ of asthma and allergies.
