There are fears that this summer could be extra bad for millions of hay fever sufferers because of the cold spring.
Hay fever is a common allergic reaction to pollen, a fine powder released by plants.
At the moment there is no cure for hay fever but most people are able to relieve their symptoms with medication.
But here are some quick tips for beating pollen in the summer:
- Wear wraparound sunglasses to stop pollen getting in your eyes when you are outdoors.
- Change your clothes and take a shower after being outdoors to remove the pollen on your body.
- Try to stay indoors when the pollen count is high (over 50).
- Avoid playing or walking in grassy areas, and camping.
- Rub a small amount of balm inside your lower nostrils. This can help stop pollen getting in your nose.
- Don't keep fresh flowers at home.
- Keep your home pollen free by regularly vacuuming and dusting with a damp cloth.
- Keep pets out of the house - if your pet does come indoors, wash them to remove any pollen from their fur.
- Keep the windows closed when riding in a car.
