In China, as of December 2016, the size of China’s Internet users reached 731 million, of which 695 million were cell phone users. Based on this calculation, the proportion of China’s Internet users using cell phones to access the Internet is 95.1%. In other words, for every one hundred people, there are 95 low-headed people. That’s right, that’s you! So what are the hidden dangers of low-headed people? Obesity Thailand’s Ministry of Public Health (Department of Public Health) spokesman Dr. Phanphimon Wipulakorn recently pointed out in an interview that more and more Thai people are used to using smart phones for long periods of time, which will have a very negative impact on health. Dr. Phanphimon added that in addition to the risk of obesity, prolonged cell phone use will cause damage to the fingers, shoulders and even the back. Dr. Phanphimon suggested that people put down their phones for a while and keep proper exercise is the way to live a healthy life. Cell phone neck According to a new study published by the New York Crest Surgery and Rehabilitation Center in the journal Surgical Technology International, a buried head playing with a cell phone can put excessive pressure on the neck, which can lead to problems with the crest. Generally speaking, the average human brain weighs 10 to 12 pounds, but the neck tilts when playing with a cell phone with the head down, which leads to increased pressure on the crest. Looking down at the phone also tends to cause stiffness and spasm in the neck and shoulder muscles, and over time, it may lead to straightening of the cervical curvature, cervical disc protrusion, etc. There may also be signs such as probing the neck, looking down at the phone for a long time, it is easy to make the cervical joints misaligned, and may also suffer from carpal tunnel syndrome, tenosynovitis, etc. If your head is always tilted forward staring at the phone screen, it will shorten the muscles of the neck and increase the gravitational force on the cheek area, leading to a sagging jaw, which will also lead to sagging cheeks and so on. But in any case, looking at the phone is inevitable, and look at the correct posture! If you can’t insist on the correct posture, please look at the phone less; if you can’t insist on looking at the phone less, please understand the small knowledge of neck protection. Rotate your head and neck Take a standing or sitting position, cross your arms, rotate your head and neck to the left and right in turn, whenever you turn to the maximum, turn a little and then exceed the original amplitude. Both eyes also try to look backward or upward. Rotate 10 times on each side. Look up and watch the sky Take a standing or sitting position. Cross your arms, tilt your head and neck back and look at the sky, and gradually increase the amplitude, stop for a few seconds and then restore, do 8 times. Neck and arm resistance Take a standing or sitting position, cross your hands tightly against the occiput behind your head. Head and neck force backward extension, the hands forceful resistance, continued confrontation for several seconds after the bell restored. Do this 6-8 times in total. Rotate left and right with arms crossed, slowly turn your head to the left side, while inhaling in the chest, so that the right side of the neck straight, stay for a moment, then slowly turn to the left side, while whistling, so that the left side of the neck straight, stay for a moment. Repeat alternately 4 times. Lift shoulders and neck slowly lift both shoulders, neck as far down as possible, stay for a moment, slowly and relaxed shoulders down, head and neck naturally extend, restore natural, then sink both shoulders hard, head and neck upward stretch, stay for a moment, relax both shoulders, and natural whistle. Note that you should inhale slowly while stretching your neck, hold your breath when staying, and loosen your shoulders is to try to make your shoulders and neck relax. After returning to natural mode, repeat 4 more times. Eye diseases Dry eyes. According to statistics, normal people blink about 12 times a minute, but when staring at a screen, they blink only 7 times a minute on average. Reducing blinking also reduces tear secretion, which can easily lead to dry eye disease, and often leads to eye discomfort, dryness, fear of light, fear of wind, easy tearing, and red, swollen and congested eyes. This leads to a decrease in visual quality, and in severe cases, keratitis may occur. Cataract. The main reason is that the eye is exposed to high radiation for a long time, and the intraocular lens protein undergoes oxidation reaction, which gradually develops into a cloudy state as this reaction increases. Since the eye tissue contains a lot of water, it is easy to absorb electromagnetic radiation power, and the blood vessels of the eye are fine, so it is not easy to take away heat, therefore, under the action of electronic products with electromagnetic radiation, the temperature of the eye is easy to rise. And the lens and retinal tissue are very sensitive to high temperature, very easy to cause irreversible damage. LED screen light source contains a lot of blue light, is second only to ultraviolet light source of high energy short wavelength, strong penetration of eye tissue, can penetrate the front of the cornea, lens directly to the retina. These short wavelengths of light on the retina of chronic damage, increasing the chances of the retina’s central – macular lesions. In addition, blue light will also inhibit melatonin secretion, disturb sleep and increase the incidence of major diseases. How to protect your eyes? 1. Viewing distance at 6 times the diagonal of the electronic screen. 2. “20-20-20” rule: raise your eyes every 20 minutes to look 20 feet (about 6 meters) away for at least 20 seconds. 3. Maintain normal use of 3C products, do not slide the phone for a long time, stare at the computer, tablet, etc. 4. Try to use natural light sources or similar natural light sources, such as incandescent lamps, etc. 5. Supplement B C vitamins, maintain adequate sleep and rest, etc. 6. usually life can eat more food to help the eyes, such as: purple potatoes, carrots, spinach, blueberries, bananas, broccoli, goji berries, cherries, etc. are food to protect the eyes. Safety risks The improper use of cell phones not only affects life and health, but more importantly, can also endanger personal safety. Looking down at the cell phone on the road is very easy to happen accidents. Looking down at the phone, do not pay attention to the surrounding pedestrian traffic, the possibility of traffic accidents is very high. Escalators, steps, or looking down at the phone when getting on and off the bus, are also actually very dangerous. There is also driving to play with the phone, it is simply a joke with their own lives and the safety of others. Low-headed people’s “cell phone dependence”, in addition to causing disease and possible accidents, so that we should have some of the normal ability in gradually fading, such as the ability to get along with people, the ability to cooperate with people, the ability to communicate with people.
