How about playing mobile phone shoulder ache, finger numbness, cervical back arch before bed?

 Cause dry eyes

A new study published in the Journal of Optometry and Visual Sciences finds that when people read text messages or surf the Internet on their mobile phones, their eyes are closer than when they hold a book or a newspaper in their hands, which means that focusing their eyes on the pictures and texts of the mobile phone is more arduous, and using the mobile phone for a long time can lead to dry eyes. In addition, it is more likely to cause headache and binocular fatigue.

Leading to blurred vision

Staring at the cell phone for a long time in a dark room, the light emitted by the cell phone will cause eye muscle fatigue, affect the focusing ability, and lead to blurred vision. Initially it may be temporary visual fatigue, but in the long run it will become permanent, leading to myopia and possibly astigmatism.

Lead to visual deviation

People are born with the same degree of binocular vision, while lying in bed for a long time and playing with mobile phones will cause visual deviation of left and right eyes for a month. Because the pressure on the left and right eyes is the greatest, so a month will cause vision deviation of the left and right eyes, pillow pressure on the eyes caused insufficient blood supply, a long time will have a sense of expansion of the eyes, short-term image overlap.

Affect vision

The pressure on the left and right eyes is greatest when lying on both sides of the body, so that within a month, the vision deviation of the left and right eyes will be caused (why some people have different degrees of left and right eyeglasses, while people are born with the same degree of two eyes, because some people like to lie on the side playing with mobile phones. The pressure of pillow on eyes causes insufficiency of blood supply. As time goes on, the eyes will have a sense of swelling. Short-term image overlap. This is not an eye drops can be good! 

Influencing the biological clock

Using a cell phone in bed for more than an hour can reduce the total amount of melatonin produced by people by about 22%. Once people's melatonin is inhibited to this extent, the physiological cycle of people will also be affected, the direct impact is that people are always in light sleep, or even greatly reduce people's sleep time. That is to say, after an hour of playing with your mobile phone, you may have to play for another three hours because you can't sleep.

Affect intelligence

Mobile phone radiation is relatively large, there are two kinds of 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 slight effect on this balance. Although it is small, it is still harmful. Long time will cause the body immunity decline, fatigue, nausea, and other adverse reactions. Long-term effects on mobile phones can also affect vision. When sleeping at night, it is recommended to play with mobile phones less. In addition, the signal reception radiation of mobile phones will affect the brain nervous system, which will reduce intelligence over a long period of time.

Numbness of fingers

Frequent keystrokes, sore thumb. Excessive use of mobile phones and frequent text messaging can lead to discomfort such as thumb soreness, numbness or swelling.

Chronic strain

The neck droops too much, the body does not bend naturally, and the neck is leaning forward more and more. This makes the human cervical sternoclavicular papillary muscle continue to stretch forward, after a long time will be in a chronic congestion state, over time easy to compress the vertebral artery and induce cervical spondylosis, resulting in chronic strain.

Cervical arch

Normal people have physiological bending of cervical spine. If there is no physiological bending, even bending in the opposite direction, it is called "back arch". "Cervical back arch" is the most common pathological basis of cervical spondylosis. High pillow can make the head flex forward, increase the stress of lower cervical spine, and accelerate cervical degeneration. The bad habits such as high back-to-back TV watching, long time internet surfing and lying on mobile phones, which drag the cervical spine for a long time, will also lead to the decrease, straightening and even reverse bow of the curve.

Damage the skin

The radiation of mobile phones to people can not be underestimated. When people use mobile phones, they are very close to the face, which will affect the skin to a certain extent. It is uncertain whether there will be spots, but it is certainly not conducive to the skin and easy to get acne.
