What harm can it do to play with a mobile phone under a quilt?

Eyes are the windows to the soul, especially at night. Basically, everyone hides under the covers and plays with their mobile phones. It's called cold in winter ~ ~ ~ but you can't forget that mobile phones have radiation. Although small, long-term accumulation will stimulate the nervous system. Of course, if you are healthy, it may take longer. There is nothing you can do about it. You must make some sacrifices if you want to play. . . . . . But there is one thing you must do! That's to protect our eyes! My myopia, the higher the degree, is also related to lying in bed playing mobile phones at night. We can only minimize the loss, so I'll give you several effective ways to reduce intraocular pressure! First, hide under the covers and play with your mobile phone at night. Try to minimize the light of the mobile phone, and then don't point the screen of the mobile phone at your eyes. Light is direct, you won't turn it by yourself (I won't consider interference diffraction), let alone radiation. It is best to tilt down about 45℃ instead of up, so the neck will be sore for a long time. Second, don't play with your mobile phone on your side! Listen carefully! Yes, never. Lying flat on the left and right has the greatest pressure on the left and right eyes, and less than a month will lead to the deviation of vision between the left and right eyes (why do some people wear glasses with different degrees, while people are born with the same degree of eyes? 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! ! Third, don't play with your stomach. It makes it difficult to circulate blood in the elbow and brain. This way is very tired and easy to fall asleep, so that the mobile phone is still connected to the internet. . . . Inertial ischemia is basically formed above the cervical vertebra. Fourth, the best way is to play with your mobile phone on your back, which is suitable for all parts of your body. Besides elbow fatigue, you can continue to play with a quilt under your elbow! This is the best way to have the least impact on health. In addition, at night, the browser screen should be set to night mode as far as possible. We perceive that fonts are recognized by color difference reaction. The greater the color difference between the two colors, the more eye-catching. The colors are white, red, orange, yellow, green, blue, purple and purple, and other derivative colors are covered. Black and white are the most eye-catching So you know why the night mode is always black and purple (or gray). Use cool colors at night, not warm colors. But there is a disadvantage: the color at night makes people feel tired easily. This is also the reason why I want to sleep after playing for less than a while at night (most people think that dark gray tone is better than black at night, which is also a color reaction problem. Fifth, try not to play for more than an hour and a half at night! After receiving a certain amount of external information, people will avoid memory (there are only two memory peaks in a day: around 10 in the morning and around 9: 00 in the evening, and the memory at other times is basically unchanged, but after 1 1 in the evening, all parts of the body start a new round of metabolism, so everyone should pay more attention).
