The attraction of mobile phones is so powerful. Nowadays, many people's eyes are inseparable from mobile phones, and they even stay up late to play with mobile phones in the dark. It seems that we forget that the light of mobile phones can cause irreversible damage to eyes. Staying up late to play with mobile phones does not only harm people's eyes. Let's talk about the bad consequences of playing mobile phones before going to bed for a long time.
Hazard 1: sudden death
According to foreign research reports, people who spend two hours a day staring at TV and computer screens are twice as likely to suffer from heart disease. It is easy to cause sudden cardiac death by playing with cell phone for a long time.
Hazard 2: vision loss
Generally speaking, the degree of two eyes is the same from the time of birth, and long-term lying in bed playing with mobile phone for a long time before going to bed can easily lead to the decline of vision, and the degree of left and right eyes is not the same.
Whether it is lying on the left side or looking at the right side, the pressure on the eyes is the biggest, and the pillow will also cause pressure on the eyes, resulting in insufficient blood supply. As time goes on, the eyes will have swelling feeling, short-term image overlap, and even affect vision.
In addition, staring at the eye in the dark environment can easily lead to blurred vision. At first, it may be temporary visual fatigue, but in the long run, it will become permanent, eventually leading to myopia, and may even lead to retinal detachment.
Hazard 3: loss of self-control ability
Psychological experts believe that people always can't help playing with mobile phones before going to bed, which is a manifestation of the loss of self-control. In short, it means that you can't control your behavior, and you will be disappointed and self reproached. You may even be in a conflict between "should sleep" and "can't put down your mobile phone", so as to cause inner agitation. This will have a great impact on people's mood in the long run, which can lead to depression in severe cases.
Hazard 4: affecting the biological clock
Using a cell phone, tablet or other light emitting electronics for more than an hour in bed can reduce the total amount of melatonin produced by about 22 percent. Once people's melatonin is inhibited to this extent, then the physiological cycle of people will also be affected. The direct impact is to keep people in shallow sleep, and even greatly reduce people's sleep time. In other words, after playing with your mobile phone for one hour, you may have to play for another three hours because you can't sleep.
Hazard 5: chronic strain
The neck droops excessively, the body does not bend naturally, the neck inclines forward more and more. This makes the sternocleidomastoid muscle of human neck continue to stretch forward. After a long time, it will be in a chronic hyperemia state. Over time, it is easy to compress the vertebral artery and induce cervical spondylosis, resulting in chronic strain.
Hazard 6: affect intelligence
Mobile phone radiation is relatively large, there are screen radiation and body signal receiving 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 slight effect on this balance. Although it is not big, it is still harmful. A long time will cause body immunity to decline, easy to fatigue, nausea, and other adverse reactions. Long time exposure to a cell phone can also affect vision. It is recommended to play less mobile phones when sleeping at night. In addition, cell phone signal reception radiation will affect the human brain nervous system, a long time will make intelligence decline.
Hazard 7: skin damage
In fact, the radiation of mobile phones should not be underestimated. When people use the mobile phone, the distance is very close to the face, which will have certain impact on the skin. It is not sure whether there will be spots, but it is certainly not conducive to the skin and easy to get acne.

Frequent keystroke, thumb ache. Excessive use of mobile phones and frequent text messages can lead to thumb pain, numbness or swelling.
