Why are my eyes streaming? #pollen

Pollen levels are forecast to be high or very high in many parts of the UK over the next five days.

The fine powder released by certain grasses, trees and plants is causing chaos for the many who’re allergic to pollen.

Itchy eyes, sneezing, dripping noses, scratchy throats and headaches are a common complaint.

So what can you do to feel better?

If you’re sneezing hundreds of times day, your eyes are watering and you’re sleeping badly then it’s probably hay fever.

You’re not alone – around one in five people are allergic to pollen and the culprit is usually grass, although trees can also trigger symptoms.

Early summer is often peak pollen season, when the number of grains of pollen in the air multiplies.

This year the warm weather in the UK, plus last year’s too, means conditions have been ideal for birch tree pollen – a major hay fever trigger.

Recent warm, dry days in some parts of the UK have helped spread pollen through the air, creating what’s been dubbed a ‘pollen bomb’.

Cities often have lower pollen counts than rural areas, but pollution in urban areas can make symptoms worse.

In the long term, it’s likely that a changing climate will have an impact on hay fever.

Changing temperatures and rainfall could make the pollen season longer and increase the concentration of pollen in the air.

There’s no cure for hay fever, but there are medicines you can take to feel a bit better.

Allergy expert Professor Stephen Till, from Guy’s and St Thomas’ Hospitals in London, recommends “a cocktail approach”.

That means taking:

• antihistamine tablets or drops that don’t tend to make you feel sleepy and are long acting
• plus a steroid nasal spray
• and eye drops

“They all work in different ways and are all very safe for most people – just go to a pharmacy for advice,” Prof Till says.

These products can all be bought over the counter in your local chemist. Some types work better for some people than others, and prices vary, so it’s important to try lots of different ones.

Antihistamine medicines help dampen down your body’s allergic reaction to pollen. You can start taking them three or four days beforehand.

One idea is to keep a diary of symptoms and medicines, so you can tell the pharmacist what you’ve already tested out.

Avoiding hay fever triggers is essential too, says pharmacist Ashley Cohen from Leeds.

“I always say it’s about good hygiene – pollen sits on your face and arms when you go outside, so have a shower and change your clothes when you come in.”

And he warns that pets are “brilliant vehicles” for bringing pollen into your house.

Other things the NHS says you can do include:

• putting nasal balms or jelly around you nostrils to trap pollen
• wearing sunglasses, mask or a cricket hat to stop pollen getting into your nose and eyes
• vacuuming and dusting your home regularly
• trying out a pollen filter in the air vents of your car

Also, try to avoid:

• cut grass or walking on grass
• keeping fresh flowers in the house
• smoking or being around smokers
• drying clothes outside

“Ninety percent of people with hay fever can be managed with over-the-counter medication,” says pharmacist Ashley Cohen.

If your hay fever becomes really debilitating, then you’ll need to see your GP who can refer you to specialist – but that will mean waiting for a while.

Immunotherapy treatment might be available for the worst affected. That’s when tiny amounts of pollen are injected into the body over time to get it used to the substance, so that it no longer overreacts.

The NHS stopped offering the steroid injection Kenalog years ago for hay fever because of the risk of serious side-effects. The charity Allergy UK does not recommend anyone use it either, and private clinics are no longer allowed to advertise the drug.

Afraid not. Bees don’t pollinate grass and trees – they pollinate flowers, which don’t cause hay fever.

So there’s no evidence that spreading local honey on your toast will help hay fever caused by grass and tree pollens.
