We do eye exercises. We wear sunglasses. We do a lot of things to protect (保护)our eyes. But we usually forget another important part of our body—the ears.
Ears help us hear the world. But many things, such as loud noise, can cause hearing loss (听力丧失).Once this happen, it's hard to get your hearing back. March 3 is Ear Care Day. It reminds us to take good care of our ears. So how can we protect our ears? Let's take a look together.
Keep your ears dry and warm
Dry your ears with a towel (毛巾) after swimming or taking a bath. If you feel water in your ear, shake your head a little bit. This can help you get the water out of your ear.
Also, when the sun is shining, wear some sunscreen (防晒霜)on your ears. During the winter, protect your ears with a hat or a scarf.
How to clean your ears
Usually, our ears can clean themselves. The earwax (耳屎) builds up, dries out, and then comes out of the ear along with some dirt (污垢).
So don't clean your ears with anything sharp (尖锐的). Sharp objects can make the earwax go too deep into your ears and hurt them. But if the earwax is making you feel bad, you can ask a doctor for help.
How to use headphones
Don't listen to loud music on your headphones for a long time. Follow the 60:60 rule:listen to music at 60 percent of your headphones' maximum volume (最大音量) for no more than 60 minutes a day.
Over the-ear (头戴式) headphones are better than in-ear (入耳式) ones. They do a better job of stopping outside noise, so you can listen at a lower volume.
