The Symptoms of Hayfever

Both seasonal allergic rhinitis (hayfever) and year around allergic rhinitis (perennial) produce essentially the same symptoms, but with different severities.

The symptoms of hayfever come from a localised allergic reaction in the nose, throat and eyes. Once an allergy to a particular pollen has been established (see ‘How an allergic reaction develops’ for further information), any further contact with it will stimulate the immune system to release histamine and other chemicals. These then act as a trigger for common ‘hayfever’ symptoms such as...

  • Sneezing
  • A runny nose
  • A stuffy nose (congestion)
  • Itching of the eyes, nose, and back of the throat
  • Itching, watery and inflamed eyes (conjunctivitis)
  • A dark appearance under the eyes due to inflammation in the sinuses
  • Coughing
  • Loss of sense of smell and taste
  • Tiredness
  • Sensitivity to light
  • Headache
  • Asthma may become worse (Seek medical advice from a qualified healthcare professional if symptoms are persistent or become more severe).


On top of all these symptoms, hayfever sufferers may feel miserable, irritable and listless and many people find their ability to work, drive and enjoy a social life is impaired.
