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 mobile phone on 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. This is suitable for all parts of the body, except 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, try to adjust the browser screen to night mode at night. We perceive that fonts are recognized by color difference reaction. The greater the color difference between the two colors, the more troublesome it is. The colors are white, red, orange, yellow, green, blue and purple, and other derived colors are covered inside. 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 tone response problem, which is not discussed much)
5. 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). In addition, open the browser!
6. Don't turn on the small desk lamp when playing mobile phone at night. After 1 1 half past one in the evening, the body will secrete protease that inhibits melanin. This effect can last until 4 am, but if you see light during this time, the body will stop secreting. . There will be secretion before one o'clock, and it will decompose after one o'clock (look at your little faces ~ ~ especially girls, whether there are freckles. There are only three reasons: too many suns; Washing your face is not clean; Lack of sleep. The first reason is basically ruled out in winter. If there is no sun, even if there is, the light intensity is limited. As for the second one, didn't you wash your face? Well, it depends on your own cleanliness. The third one is up to you. ) Then the bags under the eyes will turn black and it will take a long time to get better.
7. Avoid eating a lot before playing mobile phone in bed at night. Well ... I think a lot of people do. They eat a lot before playing with their mobile phones under the covers at night, and they are afraid of falling asleep ... I didn't expect that the more they play, the more energetic they will be ... (The advantage of eating at night is that you can delay the arrival of your biological clock. The disadvantage is ... the next day, my eyes were swollen, and my stomach was going to go on strike for a long time! )
