Is it true that it is true to swipe your phone before going to bed?

A few days ago, the topic of "research found that playing with mobile phones and hurting the eyes before going to bed" has aroused the attention of netizens. The origin of this statement is an English technology report, which introduces a research recently published in "Natural Communications". Researchers at the Barc Institute of Barc found that restrictions on diet have the effect of extending the life of fruit flies. The specific mechanism is to activate some rhythmic genes, and an unexpected discovery is that the expression of these rhythm genes is related to light sensors. Later, the researchers let the researchers let the researchers let the researchers allow Drone flies have been in a dark environment for a long time, reducing the stimulation of light to its visual cells, and the life of the fruit flies has been extended. Researchers believe that this indicates that the stress and activation of the light sensor can hinder the extension of the life of fruit flies.

It is really worrying to look at this conclusion alone. In the modern living environment, everyone is inseparable from electronic products such as mobile phones, computers, and swinging mobile phones before going to bed at night. It is the habit of many people. So, how to avoid damage to the eyes as much as possible? Does it really affect life?

The psychology is relaxed, the eyes are "overworked"

Many people have such feelings: work and busy with baby for a day, only to enjoy a relaxed and quiet time before going to bed. For them, mobile phones are like a tool that sets a lonely atmosphere, and it doesn't matter whether to watch news, videos, novels or chatting. In other words, the mobile phone carries the function of psychological comfort at this time.

However, the eyes are nervous with psychological relaxation. Because when people are asleep, their eyes are full of eyes. When we work, they are working. When we think that "rest", we are still working. Moreover, watching the phone before going to bed at night, because there are no other things waiting for the process of "queuing", I often forget to look at the time. One or two hours fleeting, thereby increasing the burden on the eyes.

What changes will the eyes happen during watching the phone at night?

From a medical perspective, first of all, the blink of an eye when the eyes are focusing on the mobile phone, the tears on the cornea surface will become unstable and easy to rupture, and the tears will evaporate quickly. At that time or the next day, when the eyes appeared dry, fatigue, tears, and do not want to open their eyes, it was likely that dry eye disease had followed. There is also a term "video terminal syndrome" in medicine, which means that various discomforts caused by electronic screens such as mobile phones and computers are formed. This is directly related to the use time of the screen. The heavier, the severe cases may cause corneal epithelium damage, even eye pain, headache and other symptoms.

Secondly, when using the eyes for a long time, the ciliary muscle will continue to shrink and spasm, causing people in all ages to cause obvious fatigue and even dizziness. For adolescents, the continuous contraction of eye and ciliary muscles for a long time will induce the continuous progress of myopia; for middle -aged and elderly people, this move may reduce the elasticity of the crystal body, aggravate the eye eyes and even cataract.

Third, in the case of insufficient light at night, the pupils will naturally spread. If there are special anatomical structures such as the front room and the narrow corner of the house, it is possible to induce glaucoma in the dark environment for a long time. Eyes are severe pain, even headache, nausea, vomiting and other symptoms.

Eye protection mode cannot be completely eliminated

In addition to the impact on the eyes, the most common negative role of watching mobile phones at night is to affect sleep. This principle is well explained. Looking at the mobile phone before going to bed, all the information passed to the brain will cause the cerebral cortex and sympathetic nerves to varying degrees, which in turn causes the plant nervous system and biological clock disorders. Studies have also proved that the blue light released on the screen of mobile phone will inhibit the synthesis of melatonin (a kind of hormone that induces natural sleep), thereby aggravating sleep disorders such as difficulty in sleeping, easy to wake up and dreaming, and reduce sleep quality.

Now many electronic products have launched eye protection mode. By adjusting the color temperature of the screen, the screen becomes "yellow". The mobile phone highlights red and green light through the software algorithm, thereby reducing the output of blue light to a certain extent and increased. The comfort of the mobile phone. However, don't think that the eye protection mode can protect the eyes. On the one hand, the eye protection mode can only block a certain degree of blue light without blocking all. On the other hand, the screen in the eye protection mode will be relatively darker, and the contrasting degree is relatively decreased. Essence Therefore, the most effective eye protection method is still to reduce the length of watching the electronic screen, rather than relying on the so -called eye protection mode.

Others say that the color of the screen color of the mobile phone into green is good for the eyes. Is this scientific saying? Color psychology believes that green can make people feel comfortable and calm. The reason may be that the green light is in the center of the visible spectrum, and the human eye is more sensitive to green recognition, but its eye protection effect has no clear evidence -based medical evidence.

In addition, the bad posture of swiping mobile phones before going to bed may cause lumbar and cervical diseases. Some people see that mobile phones are accustomed to soft pillows on the back and behind their necks. In the short term, they have a comfortable feeling. However, maintaining this posture for a long time, the lumbar spine is suspended and the lack of effective support will cause the pressure of the lumbar disc herniation and induce lumbar disc herniation. Similarly, the long -term forward flexion and force of the cervical spine can also lead to stiffness and sore cervical spine, inducing cervical spondylosis.

The saying of "injury life" has no empirical

Night brushing mobile phones is really not good for eye health, but it is questionable to say that it affects life.

The research conclusions mentioned earlier, the research object is fruit flies. Fruit flies have a short life. In the research of life science, for genetic studies related to genes, especially aging, it is a very ideal scientific research model, but compared with humans, fruit flies are different from humans. huge. Therefore, it is not advisable to simply infer the results obtained by using fruit flies experiments. If you read the research papers carefully, you can find that the conclusion of the article is cautious, and the relationship between the visual system and life is very complicated from a macro perspective. It is far from a experiment to study thoroughly. In a sense, visual systems consume a lot of energy and resources for life, but at the same time, it is necessary for most biological foraging, puppets, and survival. Therefore, it is not possible to simply say that the visual system accelerates aging. Objectively speaking, there is a complex relationship between the visual system and the aging, and the two have also reached a subtle balance in the evolution of life.

On the other hand, the results of research sometimes bring people inspiration, but it can only stay in the laboratory, not to be promoted to the real world, even if it is a real fruit fly world. Fruit flies in the laboratory can delay aging in darkness for a long time, but in the real world, fruit flies have shortened their life due to the loss of visual systems that they cannot find food and avoid natural enemies. Similarly, there are many factors that affect the expected life expectancy in the real human world. Even if the activation of human eye lighting cells is indeed negatively related to life expectancy, it is difficult to exceed the impact of genetic, environmental, medical conditions and other factors. Differences.

Therefore, "playing mobile phone before bedtime will shorten life" is not a scientific judgment.

The key to healthy use is to control the duration

During the day, I was exhausted, but I was lying on the bed at night, but my mobile phone was brushed until late at night. This behavior was also known as "retaliated sleep procrastination." According to related research, this behavior may be a psychological compensation to fight against the pressure that will suffer during the day. Generally speaking, the greater the pressure and the more often suppressing their wishes during the day, the more prone to revenge sleep delay. Reverse sleep procrastination gives people the illusion of living control, but in fact decreased sleep time can lead to a series of side effects such as decision -making ability and decreased cognitive ability.

In the era of mobile Internet, people's lives are increasingly inseparable from mobile phones, but we can use mobile phones as healthy as possible.

For office workers, the key to using mobile phones to use mobile phones is to control the time of watching mobile phones. When using mobile phones to relax before going to bed, you need to remind yourself to stop, try not to exceed half an hour; keep staring at your mobile phone and computer screen during the day. When you feel tired of your eyes, you stand up and look at the distance.

For adolescent myopia prevention and control, there is a "20-20-20" rule, that is, 20 minutes after the eye with the eye at a close range, overlook 20 feet (about 6 meters) in the distance for more than 20 seconds. We can also promote this rule to the time to look at the electronic screen, which can greatly relieve the fatigue and discomfort in the eye. Children do not use their mobile phones as much as possible, let alone watch the electronic screen at night.

What the elderly need to pay special attention is that you should not watch your mobile phone in a dark environment. Do not turn off the indoor environment lights for power saving or worry about affecting the rest of the family. At the same time, you must adjust the brightness of the mobile phone screen appropriately to make it match the brightness of the environment. In addition, pay attention to the posture of the mobile phone, do not lie down for a long time, so as not to aggravate damage to the neck, waist and other parts.

Finally, people with contact lenses should be reminded, remember to take off the contact lenses before watching the phone before going to bed. If you accidentally fall asleep, wearing contact lenses all night may cause problems such as corneal epithelium and conjunctivitis.

In this era, various visual information was overwhelming, bringing huge challenges to eye health. 70%~ 80%of the information obtained by humans comes from vision, so we must protect this important sensory organ. If you look at the symptoms of sour eyes and fatigue behind the electronic screen for a long time, this is the early warning signal from the body. We can try to change the eye habits and reduce the time to watch the screen. Do a hot compress before going to bed at night. If you use hot compresses, it will help relax the eye neuromuscular muscles and relieve fatigue.
