Hay Fever
Hay fever, also called seasonal allergic
rhino-conjunctivitis, occurs in the spring and
summer, and affects the eyes and nose. It is
also linked to oral allergy syndrome.

18. • Causes of hay fever
Hay fever is caused by breathing in pollen
particles and by pollen getting into the eyes.
You can get hay fever at any time from early
spring to late summer, depending on which
pollen or pollens you're allergic to.
The pollens most likely to cause problems
in early spring are those from trees such as
the silver birch, ash, oak and London plane.
Grasses pollinate during mid-summer from
May to August. The most profusely pollinating
grasses are timothy, rye, cocksfoot, meadow
and fescue.

19. The main Symptoms of hay fever
• Repeated sneezing attacks
• Runny or itchy nose
• Itchy or watery eyes
• Itchy throat, palate and ears
• Loss of concentration
• General feeling of being unwell (hence 'fever')

20. • Preventing hay fever
• If you have hay fever, there are steps you can take
to avoid exposing yourself to pollen:
• Keep an eye on the pollen count (often included
in weather reports) and stay inside as much as
possible when it's high.
• Wear wrap-around sunglasses to stop pollen
getting in your eyes
• Saline douches or a little Vaseline applied inside
the nose will reduce symptoms
• Keep car windows closed and switch on the air
conditioning to prevent pollen entering the car

21. • Keep bedroom doors and windows closed in
mid-morning and early evening when pollen
levels peak
• Avoid areas such as parks or fields, particularly
in the early evening when there's a lot of
pollen floating at nose level
• Get someone else to mow the lawn and don't
lie on freshly cut grass
• Change into clean clothes when you come
home and wash the clothes you wore outside
