Market research and consulting company Gartner released the latest survey report that the total number of mobile phone users in China exceeded 1 billion for the first time in 2013. Gartner analysts predict that in 2014, 443.5 million mobile phones will be sold in the Chinese market, and more than 1.075 billion mobile phones will be in use.

There are 41 people in our class. According to the survey, everyone has a smartphone on hand (not excluding some rich people who have two). From Samsung to Apple to Nokia, the price ranges from 800 to 3,000.

According to the survey, 89% of students use mobile phones to surf the Internet every day, and 92.3% of students said they use their mobile phones to play games and watch videos online in class. Even 45% of students said they often use mobile phones to surf the Internet in class. As for playing with mobile phones before going to bed at night, 100% of them will check their mobile phones before going to bed, including refreshing Moments, Weibo, and Space. But half of the students will read e-books or movies for a while before going to bed.

Analysis: Communication software has the largest number, which reflects that mobile phones are mainly tools for communication.

Judging from the statistics of learning software, most of them are auxiliary learning software.

The course grid eliminates the need for students to print out course schedules, and the software will notify them in advance of what classes will be held the next day. Youdao Dictionary and Jinshan Dictionary help to better learn English words and translations, and more students will have several CET-4 and CET-6 vocabulary and listening training software on their mobile phones, which reflects the importance of CET-4 and CET-6 among students. influence and the good wish to pass the exam in one go.

1. Influence the biological clock

Using a mobile phone, tablet, or other electronic product that emits light for more than an hour in bed will reduce the total amount of melatonin produced by people by about 22%. Once people's melatonin is suppressed to this extent, the person's menstrual cycle will also be affected. The direct impact is that people will always be in light sleep, and even greatly reduce people's sleep time. In other words, after playing with your mobile phone for 1 hour, you may have to play for another 3 hours because you can no longer sleep.

2.Chronic strain injury

The neck droops excessively, the body bends unnaturally, and the neck leans forward more and more. This causes the sternocleidopapillary muscles in the human neck to continuously stretch forward, and over a long period of time, they will be in a state of chronic congestion. Over time, it is easy to compress the vertebral artery, induce cervical spondylosis, and cause chronic strain.

3. Affect vision

Lying on the left and right sides puts the greatest pressure on the left and right eyes. If this continues within a month, it will cause vision deviation in the left and right eyes (why some people wear glasses with different degrees on the left and right, but the degree of the two eyes are the same when a person is born, is because some people I like to lie on my side playing with my mobile phone, reading novels, and comics.) The pressure of the pillow on the eyes causes insufficient blood supply. Over time, the eyes will feel swollen and the images will overlap for a short time. This cannot be cured by dropping eye drops! So! Really, for the sake of our eyes, we really shouldn’t do it!

4. Cervical arching

We normal people all have physiological curvature of the cervical spine. If there is no physiological curvature, it may even bend in the opposite direction, which is called "reverse arch". "Cervical back arch" is the most common pathological basis of cervical spondylosis. A high pillow can bend the head forward, increase the stress on the lower cervical spine, and may accelerate the degeneration of the cervical spine. Bad lifestyle habits such as lying on a high back and watching TV, surfing the Internet for a long time, lying down and playing with mobile phones, etc., will stretch the cervical spine for a long time, which will also cause the lordosis of the curve to gradually decrease, become straight, and even arch.

5. Affects intelligence

The radiation of mobile phones is relatively large, and there are two types of radiation: screen radiation and body signal reception radiation. The blood in the human body needs to maintain a balance of positive and negative charges. The radiation from the screen will have a subtle impact on this balance. Although it is not large, it is still harmful. Over time, it will cause a decline in the body's immunity, fatigue, nausea, and other adverse reactions. Looking at your phone for a long time can also affect your vision. It is recommended to play less mobile phones when going to bed at night. In addition, the signal reception radiation of mobile phones will affect the human brain nervous system, which will reduce intelligence over time.

6. Damage to skin

The radiation of mobile phones to people should not be underestimated. When people use mobile phones very close to their faces, it will have a certain impact on the skin. It is not certain whether it will cause spots, but it is definitely not good for the skin and can easily lead to acne.

suggestion:

First of all, you must self-restraint on the time you use your mobile phone. Self-control is the most important. If a person cannot control himself, then there is nothing others can do. Not only should we control the daytime, but we should also pay attention not to use mobile phones for too long at night and get a good rest.

Secondly, we must enrich our spare time life and divert our attention. Divert the time you spend on your phone to things like going out, chatting with friends, walking, working out, participating in some physical exercises, etc.
