We do eye exercises. We wear sunglasses. We do lots of things to protect 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 noises, can cause hearing loss (听力丧失). Once (一旦) this happens, it’s hard to get your hearing back. 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 clean themselves. The earwax (耳屎) builds up, dries out, and then comes out of the ear along with some dirt.

Don’t clean your ears with anything sharp, or it can make the earwax go too deep into your ears and hurt them. But if your ears start to hurt, you can go to 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 headphones are better than in-ear ones. They do a better job of stopping outside noise so you can listen at a lower volume.

Teeth are important to us. We should keep our teeth healthy. Do you know how to keep teeth healthy? Here are some do’s and don’ts. Please remember them.
