One in five people in Europe is thought to suffer from hay fever, and the bad news is there's no cure for it and you can't prevent it. You'll know if you're affected. It's the itchy, watery eyes, sneezing, runny nose that don't go away like a normal cold, often combined with headaches and tiredness. After you've been to your pharmacist or Huisarts/GP for advice on the best treatments, such as antihistamine tablets, drops or sprays, here are some other tips to try. Watch the clock Certain times of the day have higher pollen levels. On a typical high count day - dry, warm and sunny - at this time of year, the first half of the morning and later in the afternoon until late evening are the times to avoid being outside. Wash it off Pollen is made up of fine, microscopic grains released into the air by grass, plants and trees. They are carried on the wind, easily inhaled by humans and pets, and they stick to everything. So, it's a good idea to wash it all off once you're home, showering, washing your hair and changing your clothes. For the same reason - if you're really suffering you should avoid drying washing outdoors on a clothes line when the pollen count is high. When is the pollen season? Tree pollen - late March to mid-May Grass pollen - mid-May to July Weed pollen - end of June to September ...And for the techies The pollen count is the amount of pollen per cubic metre measured over 24 hours at various places, using a trap with sticky paper inside it. A reading of between 50 and 150 grains of grass pollen is considered high - enough for hay fever symptoms to appear.

While you're at it, keep windows and doors shut as much as possible - especially in the early morning and evening. Know your weather Make sure to monitor the pollen forecast. When it's warm, humid and windy, the pollen count is higher. Rainfall decreases pollen concentration in the air, particularly if it rains heavily in the morning. The amount of daylight also plays a role - plants and trees will produce less pollen when it's cloudy. Wear shades Healthcare professionals recommend: wraparound sunglasses to stop pollen from getting in the eyes and putting Vaseline around the nostrils to trap pollen. The don'ts Don't keep fresh flowers in the house Don't smoke or be around people smoking, because that makes symptoms worse Don't cut grass or walk on it, or close windows if it has to be done!
