What happens to people who lie down and play with their phones for a long time in the end?
5 problems you may have to "suffer"
In the information age, mobile phones and the Internet have been integrated into our lives and gradually developed into a necessity. Mobile phones have brought intelligence and convenience to our lives, but if used improperly, mobile phones may also become a "tool" that harms health.
Many people keep their mobile phones in their hands during the day, and playing with mobile phones while sleeping seems to have become a "bedtime ritual". But this behavior will continue to harm health over time. How harmful is it? Mr. William is a vivid example.
Mr. William, 34, works in an IT company. He often has to test the computer during the day, and starts playing with his mobile phone for entertainment after dinner at night. He forgets about it and becomes addicted to it. He turns off the lights before going to bed, and also brushes his mobile phone before going to bed, every day.
Just last week, Mr. William opened his eyes in the morning and found that the left side of his vision was dark and hazy, and he could not see anything at all.
Mr. William closed his eyes to relieve it, and opened his eyes again. The situation improved slightly, but the field of vision was still insufficient. He immediately went to the doctor. After preliminary examination, the vision of his right eye was only 0.4. After further diagnosis, Mr. William found that there was a blockage of the branch artery under the retina, which was a "stroke" in his right eye.
1.A study found that 8 minutes of mobile phone use before bedtime can make the brain excited for an hour
We may all have this feeling that the more you play with your phone before bedtime, the more excited you will be. What's going on?
A US study found that playing with your phone before bedtime can keep your brain excited, thus causing delayed sleep.
The US sleep platform Sleep Junkie released a study data that asked 2012 participants to wear smart watches, limit the time of playing with their phones to 8 minutes, and then record their rapid eye movement sleep time and sleep time. (https://tinyurl.com/r4yncd8w)
The results of the study found that 78% of people who play with their phones before bedtime take an average of 60 minutes to fall asleep. When the endogenous photoreceptor cells in the retina are stimulated by the blue light emitted by the mobile phone for up to 8 minutes, it may keep the body excited for more than an hour.

The researchers explained that playing with the phone before bedtime will stimulate the secretion of adrenaline, increase the release of dopamine, and keep the brain in an excited state. Even though people know that playing with mobile phones is not conducive to sleep, they still choose to play with mobile phones.
2. Lying down and playing with your phone only hurts your eyes? Wrong! You need to pay attention to these 5 major hazards
Staying up late to play with your phone does make people happy, but this happiness may come at the cost of physical damage. Just like our eyes, when people lie in bed, the distance of the screen will unconsciously get closer, which can easily induce myopia. Incorrect posture may roughly cause vision deviation of the left and right eyes, and excessive use of the eyes may also cause diseases such as dry eyes.
Not only that, staying up late to play with your phone also has these hazards.
① Disrupting the biological clock: Brushing your phone, tablet or other luminous electronic products in bed, the blue light it emits will inhibit the production of melatonin in the body. Once melatonin is inhibited, the most direct impact is reduced sleep quality.
② Freckles will make you "ugly": Studies have found that blue light can penetrate deep into the skin, causing DNA oxidation damage, causing skin collagen loss, pores will become larger, and the skin will become rough.
③ Blue light will also cause melanin deposition, causing dark circles, freckles and other manifestations. Staying up late to play with your phone will also affect the body's hormone secretion and make it more likely to get acne.
④Causes chronic strain: Keeping a posture for a long time to watch videos or play games, the body cannot bend naturally, the neck leans forward... The muscles of the head and neck are constantly stretched forward. Over time, it will easily induce cervical spondylosis, causing chronic strain, and even "neck arch" in severe cases.
⑤ Causes of conjunctivitis: Lying down and playing with mobile phones all the time, blood is concentrated in the eyes, causing mild congestion of the root conjunctival blood vessels. Papillary hyperplasia or follicular hyperplasia may occur in the eyelid conjunctiva. If you don't pay attention to rest, it is easy to cause chronic inflammatory lesions in the conjunctival tissue, and eventually develop into chronic conjunctivitis.
The result is joint disease: playing games, typing, cutting screens, etc. all require sliding our fingers, and repetitive, high-intensity activities can easily cause excessive friction between the tendon and the tendon sheath, causing damaging inflammation, swelling, pain, etc.
3. The phone always quit, do this 4 points to minimize the harm
Many people know that playing with mobile phones before going to bed is not good, but habits cannot be changed by talking. If you have to play, you should pay attention to these behaviors.
① Don't play with mobile phones while lying on your side
The posture of playing with mobile phones while lying on your back is the least harmful to the whole body. It is recommended to tilt downward by about 45°. Never play prone, let alone side-lying. The prone posture is not conducive to blood supply to the brain, elbows, etc., and cervical spondylosis doctors are prone to inertial ischemia; lying on the left and right sides, the pressure on the left and right eyes is the greatest, which is easy to cause visual deviation.
② Don't turn off the lights to play with mobile phones
When people look at things at close range, their pupils will shrink, but in a dark environment, their pupils will expand. Therefore, playing with mobile phones in the dark will cause the opposite physiological requirements of the eyes, thereby affecting the circulation of intraocular fluid. The contrast between the screen and the dark environment is too large, which can easily accelerate eye fatigue and cause vision loss.
③ Don't play with mobile phones excessively
When playing with mobile phones for more than 30 minutes, it will inhibit the formation of melanin, thereby affecting sleep quality. Moreover, if you stare at the phone for a long time, you will blink less frequently and your tears will evaporate easily, which will cause dry eyes. Therefore, it is best not to play with your phone for more than 30 minutes before going to bed.
④Try to adapt to the night mode
The brightness of today's smartphones can be adjusted according to the external environment. If you play games at night, you can use the night mode with lower eye load, that is, lower the contrast of the phone screen to a more moderate data to reduce the stimulation of the screen brightness to the eyes.
