“I usually put my mobile phone in my bag, and I often feel like it is ringing when there actually is no phone call. Now I always want to keep it in my hand, being afraid that I might miss important calls or messages,” Miss Liu tells her doctor.

Miss Gu, a news worker, has to take her mobile phone with her all the time so as not to miss any calls from her office or readers. Gradually, she started to experience a great “panic” about her mobile phone. “Every night when I’m about to fall asleep, I often wake up with a start, feeling that my phone is ringing. Although I’m sure that I have turned it off, I still feel that it is ringing, clearly.”

The above phenomenon is what we call “mobile-phone acouasm (幻听)”. The mobile phone has now become a “new organ” in a white collar’s daily life, and “mobile-phone acouasm” has become a common phenomenon among office workers.

According to a report of China Youth Daily, “mobile-phone acouasm ” most likely results from people’s dependency on hi-tech products. It is associated with certain professions, such as salesmen, consultants and journalists. They use mobile phones almost continuously.

Constantly being in the “stand-by” mode, the strong psychological tension gives them acouasm. Meanwhile, a large number of this year’s graduates are joining the family of acouasm suffers due to the hard job-hunting experience.

“You know that the rings are not from your phone, but you always take it out and have a look. This is subconscious (潜意识) from your body sending you a signal, telling you that you must take a break to reduce your pressure,” Professor Sun Li from Huadong Normal University explains.

There are many ways to solve the problem. The professor says that the key is to deal with pressure from work. “This is just a kind of self-protection”; the most important thing is to find out the source of your pressure. And then take part in some activities that are not related to your work. You can do anything that can relax your body and mind.
