The scene of “lying in bed playing with the phone” is extremely familiar to many people, since the popularity of smart phones, before going to bed to brush microblogging, reading information, the next day the first thing to open the eyes or look at the phone. In this regard, British scientists pointed out that this cell phone psychological dependence, is also a kind of Internet addiction. The British “Daily Mail” recently reported that the International Lighting Research Center (LRC) “light and health” project leader Mariana Figueroa, Professor introduced the night in bed using more than an hour of cell phones, tablet computers or other light-emitting electronic products, will make the sleep engine melatonin reduced by 22%. The impact is not only that, in the long run formed a psychological dependence, and Internet addiction, smoking addiction is similar in nature, a night without playing with the phone, you will feel anxious and irritable, always fearful of missing a call or message. It can also harm the health of the eyes, cervical and lumbar spine. ”This is a manifestation of psychological insecurity, to rely on the information provided by the cell phone to achieve a sense of value identity, relying on the social network that exists in the phone.” The doctor explained that if you don’t use the phone to produce the above-mentioned difficult to control “withdrawal reaction”, the psychology is often in a state of entanglement, may be like quitting smoking, quit the habit. The doctor suggested that it might be a good idea to advance the time to play with the phone to two hours before bedtime, telling yourself that you can only choose one of the phone, computer or TV a day, and after playing to empty your brain for a few minutes, you can go to sleep after drifting off. Quitting any “addiction” requires strong restraint, and so does quitting the cell phone. If you are lying in bed and can’t control your hand to get the phone, then put the phone far away. When you do this for a while, you will find that you don’t look at your phone before going to bed, you don’t have to brush Twitter all the time, and your life is not missing anything.
