What are the seven hazards of playing mobile phones frequently?

1. Affect the biological clock: using mobile phones, tablets or other luminous electronic products in bed for more than 1 hour will reduce the total amount of melatonin produced by people by about 22%. Once human melatonin is suppressed to this extent, then human 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, you may have to play it for another 3 hours because you can't sleep.

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 on the left and right has the greatest pressure on the left and right eyes, which will lead to vision deviation of the left and right eyes in less than a month (why do some people wear glasses with different left and right degrees, while people are born with the same eye degree? It is because some people like playing mobile phones, reading novels and reading comics sideways. ) 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 vertebra reverse arch: We normal people all have physiological curvature of cervical vertebra. 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 mobile phone is relatively large, including the radiation of screen and the reception of body signals by radiation 2. 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.

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