1, intermittent headphones
First of all, we should understand that wearing headphones will increase the number of bacteria in the ears because the ears are closed for a long time and the bacteria can't get out. So in view of this situation, we just need to shorten the time of wearing headphones. The scientific time to wear headphones should be every 40 minutes, and rest 10 minutes. When resting, you should take off your headphones, shake your ears left and right, and clean and relax your ears.
2. Interchangeable left and right ears
This principle is similar to wearing headphones intermittently, except that you can keep your ears wearing headphones without injury. However, this method is only suitable for occupations that can wear headphones in one ear. It is best to exchange the left and right ears scientifically every 10 minute.
3. Massage your ears often
In fact, many people don't know that our small ears actually contain 103 reflex acupoints, which cover almost all organs of our body. Massage our ears often will help our hearing. The massage method is also very simple, that is, when nothing happens, try to rub your ears from the inside out.
