What will happen to people who play mobile phones before going to bed every night? The latest research gives the results

Mobile phones, computers, LED lights, can emit blue light. Previous studies have shown that exposure to artificial light at night can cause circadian rhythm disorder and increase the risk of breast cancer and prostate cancer. Recently, a study published in Spain analyzed the relationship between blue light exposure and colorectal cancer, and found that the two were also significantly correlated! < / P > < p > the researchers obtained data from about 2000 adults in Barcelona and Madrid through the MCC Spain project, including 660 colorectal cancer patients and the rest randomly selected locally. Based on the space images taken from the international space station, the researchers determined the levels of artificial light sources at night in two cities. There was a positive correlation between blue light exposure and colorectal cancer. Those who had been exposed to blue light for the longest time had a 60% higher risk of colorectal cancer than those who had been exposed to blue light for the longest time. < / P > < p > this result is related to melatonin. Melatonin affects people’s circadian rhythm. When exposed to artificial light at night, the secretion of melatonin in pineal gland of human brain will decrease, which will destroy the circadian rhythm and induce cancer. As early as 2007, the international agency for research on cancer (IARC) had considered classifying “dysrhythmic shift work” as a carcinogen. In recent years, “blue light” has become a hot topic in the medical field at home and abroad: there are studies on the carcinogenesis of blue light, studies on the effects of blue light on sleep, and even studies that blue light can induce obesity All kinds of impeachment of blue light make people talk about the color change of blue light. Blu ray, is it really that terrible? < p > < p > in fact, blue light is not a big disaster. There are many different color spectra in nature, blue light is one of them. Whether it is nature, or computers, mobile phones, electronics and other products, there are traces of blue light. The wavelength of blue light is between 400-500 nm. Because the shorter the wavelength, the higher the energy and the stronger the penetration, so the blue light is the strongest in visible light. The harm of blue light to human body is objective, such as inducing macular disease, disturbing human physiological rhythm and increasing disease risk. However, “regardless of the dose to talk about toxicity is playing rogue”! The harm of blue light to people is related to the intensity and duration of exposure. If a person is free to stare at the strong light all day long, it will be strange that the eyes are not blind! In addition, blue light is not all harmful. The short wave blue light between nanowires and nanometers, while the blue light between 450-500 nm has a certain effect on regulating biological rhythm, affecting people’s mood, sleep, memory, etc. Of course, we should not exaggerate the harm of blue light, but if we are exposed to harmful blue light for a long time, we should take precautions, such as: < / P > < p > first, blue light protection. Many anti blue glasses on the market can play a role in blocking blue light, we’d better buy in regular channels. But it needs to be emphasized that although blue glasses can block blue light, it does not mean that you can freely “roam” in the world of electronic products after wearing them, because blue glasses can not prevent myopia and relieve fatigue! In addition, too much blocking blue light is not advisable, otherwise it is easy to cause color deviation and aggravate visual fatigue, which is also not conducive to health. < / P > < p > Second, use the lamp correctly. The LED lamp that has passed the national quality inspection should be used. When using, the eyes should not face the LED light source directly. At the same time, the lampshade should be lowered to cover the light source. < / P > < p > people who often play with their mobile phones before going to bed might as well take a look at this anti glare nightlight. It is divided into warm white light and yellow light. At the same time, it adopts light control induction, and the OPP brand is also trustworthy. A small one can protect your eye health. Third, develop good eye habits. Control the time of playing with mobile phones and computers. After staring at the screen for 1 hour, you should overlook the scenery. It is suggested to take part in outdoor activities and avoid using digital products in the dark. There are still controversies about the “harm of blue light” in the medical field, but the medical research in this field will be more in-depth and comprehensive in the future. At present, what we ordinary people can do is to avoid risks in advance, reduce the time of exposure to blue light at night, reduce the dependence on electronic products, and reasonably work and rest. < p > < p > [4].
