The harm of mobile phone: the content of handwritten newspaper

1. People can access the Internet more conveniently, without having to bring a computer to connect the network cable. The convenience this brings to people's lives is obvious. It has changed people's way of life, and it will certainly develop in a more intelligent direction.

2. Because of the development of mobile phones, those various applications have also entered people's field of vision. Among them, learning is one of them. You can use the dictionary application on your mobile phone to look up words, or you can watch an open class. Let everyone's study come into life.

3. Understand the latest information in the world. For people, there is no need to subscribe to newspapers or anything. Of course, it is obviously impossible to replace newspapers and magazines at present, which may be more important for businessmen.

Second, the shortcomings:

1, radiate the body; As we all know, mobile phones have radiation effects. When the magnetic field of mobile phone is close to human body for a long time, our bones will deform and bend, resulting in pain symptoms. The radiation effect of mobile phones will also affect the development of the brain, and in the long run, there will be a phenomenon of mental decline.

2. Distraction; The harm of mobile phones goes far beyond physical harm. Walking and playing mobile phone will distract attention, lead to inattention, affect work efficiency, and even lead to emergencies.

3. Hearing loss; Long-term use of mobile phones, if the two-way phone calls are too loud, may affect our hearing, leading to hearing loss. Many people use mobile phones as a tool to watch videos and listen to music for a long time, but wearing headphones will affect our overall hearing, which is not conducive to the good development of our eardrums and even lead to hearing loss.

4. Reduce the quality of sleep; When you sleep at night, put your mobile phone aside. After we enter the dream, the radiation of the mobile phone will start to invade our brain, stimulate the normal development of the brain, wake up the nervous system of the brain, so as to make people's minds clear and the quality of sleep decline. So when you sleep at night, try not to use your cell phone or put it near your head.

5. Finger syndrome; Chatting with mobile phone for a long time, whether it is QQ chat or SMS chat, when typing, both thumbs are often controlling the screen of the mobile phone. Finger-thumb syndrome will appear when talking for a long time, fingers will bend inward, phalanges will start to loosen, and adverse reaction symptoms such as numbness, pain and soreness will appear. Be sure to use the mobile phone moderately.

6. Mobile phone dependence; For a long time, we took out our mobile phones to entertain ourselves whenever we were free. Over time, we will have a dependence on mobile phones, which is subtle.

The hazards of mobile phones can also be as follows:

1. affects the biological clock.

Using mobile phones, tablets or other electronic products that emit light over 1 hour in bed will reduce the total amount of melatonin produced by people by about 22%. And once human melatonin is suppressed to this extent,

Then people's physiological cycle will also be affected, the direct impact is that people are always in a shallow sleep state, and even greatly reduce people's sleep time. In other words, after playing the mobile phone for 1 hour, it may take another 3 hours.

Because you can't sleep anymore.

2. Chronic strain

The neck droops excessively, the body bends unnaturally, and the neck leans forward more and more. This makes the sternocleidomastoid muscle of human neck stretch forward continuously, and it will be in a state of chronic congestion for a long time. Over time, it is easy to oppress vertebral artery, induce cervical spondylosis and cause chronic strain.

3. Affect vision

Lying flat is the most oppressive to the left and right eyes, which will cause vision deviation of the left and right eyes within one month (why do some people wear glasses with different degrees, but people are born with the same degree of eyes? It is because some people like to play mobile phones sideways, read novels and read comics. ) The pressure of the pillow on the eyes causes insufficient blood supply. After a long time, eyes will feel swollen, and short-term images will overlap. This is not enough eye drops! So really, for our eyes, really don't!

4. Cervical reverse arch

We normal people all have physiological curvature of cervical spine. If there is no physiological curvature or even bending in the opposite direction, it is called "anti-bow". "Cervical spondylolisthesis" is the most common pathological basis of cervical spondylosis. High pillow can bend the head forward, increase the stress of lower cervical vertebra, and accelerate the degeneration of cervical vertebra. And bad living habits such as lying on your back and watching TV, surfing the Internet for a long time, lying on your back and playing with your mobile phone, pulling the cervical vertebra for a long time, etc., will also lead to the reduction, straightness and even retroflexion of its curve.

5. Affect intelligence

The radiation of the mobile phone is relatively large, including the radiation of the screen in radiation 2 and the signal reception of the body. The blood in the human body needs to maintain the balance of positive and negative charges, and the radiation of the screen will have a slight impact on this balance, although it is not big, it is still harmful. After a long time, it will cause adverse reactions such as decreased immunity, fatigue and nausea. Facing the mobile phone for a long time will also affect your eyesight. It is recommended to play less mobile phones when sleeping at night. In addition, the radiation received by mobile phone signals will affect people's brain nervous system, which will reduce their intelligence after a long time.

Damage the skin

The radiation of mobile phones to people should not be underestimated. When people use mobile phones, they are close to their faces, which will have a certain impact on their skin. They are not sure if they will get spots, but they are definitely bad for the skin and prone to acne.

7. Numbness of fingers

Frequent keystrokes, sore thumb. Excessive use of mobile phones and frequent texting can cause discomfort such as sore thumb, numbness or swelling.

8. disgust

Cell phones can cause allergies. Some people have inexplicable skin allergies after using their mobile phones for a short time. After inspection, it was found that it was caused by some metals such as nickel on the mobile phone.
