Spring is beautiful But not everyone loves this season. The wind in spring brings pollen (花粉) and dust(灰尘) .This makes some people sneeze and itch (发痒) .Why does this happen? Let's find out!

Your eyes itch. Your nose is running. You are sneezing. And you have rashes (疹子) on your skin (皮肤) .This is caused-by allergies (过敏)! Allergies are caused by your immune system (免疫系统) , Usually, your immune system fights against germs (细菌) to keep you healthy but when you have allergies, it acts differently and fights against things like grass, pollen or some foods. This makes you feel uncomfortable.

There are many different kinds of allergies. Food allergies are some of the most common. Many children are allergic to foods like milk, eggs and peanuts.

Some people are also allergic to pollen. They may sneeze or cough when pollen gets into their nose or eyes.

Medicine may also give people allergies. For example, penicillin (青霉素) can be fatal to some people.

Some people can't even touch water. They have a hard time taking baths.

However, there is a way to find out what you are allergic to: Skin testing. Doctors put samples of different allergens on your skin. Then they wait to see if the skin around the sample becomes red. Once you know what you are allergic to, the best thing to do is try to stay away from them.
