8 major hazards of playing with mobile phones before going to bed

1. Affects the biological clock

Using a cell phone, tablet or other light-emitting electronic product in bed for more than an hour can reduce a person's total melatonin production by about 22%. Once people's melatonin is suppressed to this extent, their physiological cycle will also be affected. The direct impact is that people will always be in light sleep, or even greatly reduce their sleep time. That is to say, after playing with your phone for 1 hour, you may have to play for another 3 hours because you can't fall asleep.

2. Chronic strain

The neck is drooped too much, the body is bent unnaturally, and the neck is leaning forward more and more. This causes the sternocleidomastoid muscle in the human neck to be continuously stretched forward, and after a long time it will be in a state of chronic congestion. Over time, it is easy to compress the vertebral artery and induce cervical spondylosis, causing chronic strain.

3. Affect vision

Lying sideways puts the greatest pressure on the left and right eyes. If you continue like this for less than a month, the left and right eyes will have vision deviations (why some people wear glasses with different degrees for the left and right eyes, while people are born with the same degree for both eyes, it is because some people like to lie sideways to play with their mobile phones, read novels, and read comics.) The pressure of the pillow on the eyes causes insufficient blood supply, and after a long time, the eyes will feel swollen and have short-term image overlap. This cannot be cured by eye drops! So really, for the sake of our eyes, we must never do it!

4. Cervical kyphosis

Normal people all have a physiological curvature of the cervical spine. If there is no physiological curvature, or even if it bends in the opposite direction, it is called "reverse arch". "Cervical kyphosis" is the most common pathological basis of cervical spondylosis. A high pillow can cause the head to flex forward, increase the stress on the lower cervical spine, and may accelerate cervical degeneration. Bad habits such as lying on a high backrest to watch TV, surfing the Internet for a long time, or playing with mobile phones while lying down will cause the cervical spine to be stretched for a long time, and its lordosis will gradually decrease, become straight, or even become reversed.

5. Affects intelligence

The radiation from 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 effect on this balance. Although it is not large, it is still harmful. Over time, it will cause a decrease in the body's immunity, fatigue, nausea, and other adverse reactions. Looking at the phone for a long time can also affect your eyesight. It is recommended to play less with your phone before 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 the skin

The radiation from mobile phones to humans should not be underestimated. When people use their mobile phones, they hold them very close to their faces, which 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 may cause acne.

7. Numbness in fingers

My thumbs hurt from pressing the keys frequently. Excessive use of mobile phones and frequent text messaging can cause discomfort such as soreness, numbness or swelling in the thumb.

8. Allergies

Cell phones cause allergies. Some people develop skin allergies for no apparent reason just after using their mobile phones for a short period of time. After much investigation, I found out that it was certain metals such as nickel in the mobile phone that caused the problem.
