What harm does surfing the Internet do to your health every day? Thank you and God bless you. If you sit in front of the computer for a long time without LCD, your body will be exposed to too much radiation, which will affect your health. It mainly includes electromagnetic radiation (various electromagnetic rays and electromagnetic waves, etc.). ), sound (noise), light (ultraviolet, infrared radiation and visible light, etc. ) and other radiation "pollution" generated and emitted by computers at work. Judging from the degree of harm, electromagnetic radiation is undoubtedly the most harmful. Research by medical experts at home and abroad shows that long-term and excessive electromagnetic radiation will directly harm human reproductive system, nervous system and immune system, and it is the main inducement of cardiovascular disease, diabetes and cancer mutation, the inducement of abortion, infertility and teratogenesis of pregnant women, and it can directly affect the development of body tissues and bones of minors, leading to the decline of vision, memory and liver hematopoietic function, and even lead to retinal detachment in severe cases. In addition, electromagnetic radiation also brings hidden dangers to information security, which can be received and decoded by special signal receiving equipment, leading to information leakage and unnecessary losses. Excessive electromagnetic radiation will also interfere with other electronic devices around, affecting their normal work, resulting in electromagnetic compatibility (EMC) problems.
Please accept it, thank you!
What's the harm of noise? Thank you, great god Noise is noise. It is a kind of sound that causes people to be agitated or loud and is harmful to human health. Noise usually refers to those unpleasant and boring sounds. The waveform of noise is chaotic. From the perspective of environmental protection, any sound that affects people's normal study, work and rest, and any "unwanted sound" that people make on some occasions, is noise. Noise pollution mainly comes from social noise such as traffic, vehicle horn, industrial noise, building construction, concert hall, tweeter, morning market and people talking loudly. In the Law of People's Republic of China (PRC) on the Prevention and Control of Environmental Noise Pollution formulated by China, the phenomenon that it exceeds the national environmental noise emission standard and interferes with others' normal life, work and study is called environmental noise pollution. The decibel of sound is the unit of sound pressure level, which is recorded as dB. Used to indicate the size of the sound. The "People's Republic of China (PRC) Urban Regional Noise Standard" clearly stipulates the maximum limits of environmental noise in five urban areas: sanatorium area, senior villa area and senior hotel area, 50dB during the day and 40dB at night; Areas dominated by houses and cultural and educational institutions, 55dB during the day and 45dB at night; Residential, commercial and industrial mixed zone, 60dB during the day and 50dB at night; Industrial zone, 65dB during the day and 55dB at night; Urban trunk roads, inland waterways and areas on both sides of primary and secondary railways are 70dB during the day and 55dB at night (from 22: 00 to 6: 00am the next day at night). According to national standards, the noise in residential areas should not exceed 50 decibels during the day and should be lower than 45 decibels at night. If it exceeds this standard, it will be harmful to human body. So, what is the noise standard of indoor environment? The fourth paragraph of Article 5 of the National Method for Measuring Environmental Noise in Urban Areas stipulates that when measuring noise indoors, the indoor noise limit is lower than the standard value of the area where it is located, that is, 10dB. Harm of noise to people With the development of industrial production, transportation, urban buildings, the increase of population density and the increase of household facilities (audio, air conditioning, television, etc.). ), environmental noise is becoming more and more serious, which has become a major public hazard that pollutes the human social environment. Noise has regional, temporal and frequency characteristics. Noise will not only affect hearing, but also have adverse effects on people's cardiovascular system, nervous system and endocrine system, so some people call noise "a chronic poison that kills people." The physical and psychological harm of noise mainly includes the following aspects: (1) It interferes with rest and sleep and affects work efficiency. Rest and sleep are the necessary conditions for people to eliminate fatigue, restore physical strength and keep healthy. But the noise makes people fidget, making it difficult to rest and fall asleep. When people can't sleep after tossing and turning, they will feel nervous, shortness of breath, increased pulse, excited brain, and feel tired or weak limbs the next day. Thus affecting work and study, over time will get neurasthenia, manifested as insomnia, tinnitus, fatigue. After people fall asleep, even the noise of 40-50 decibels will change from a sleep state to a semi-sleep state. When people sleep, their brain activities are slow and regular, and they can get enough rest. However, in the semi-sleep state, the brain is still in a tense and active stage, which will make people unable to get adequate rest and physical recovery. (2) reduce work efficiency. The study found that noise exceeding 85 decibels can make people feel agitated, and people will feel noisy and unable to concentrate on their work, resulting in reduced work efficiency. (2) We all have the experience of damaging the hearing and visual organs. When I get off the plane or come out of the forging workshop, my ears are always buzzing, and I can't even hear the voice of the other party clearly, but I will recover after a while. This phenomenon is called auditory fatigue, which is a protective response of human auditory organs to the external environment. If people are affected by strong noise for a long time, their hearing will be weakened, leading to organic damage of hearing organs and hearing loss. ① Strong noise can cause ear discomfort, such as tinnitus, earache and hearing loss. According to the measurement, noise exceeding 1 15 decibels can also cause deafness. According to clinical medical statistics, if you live in a noise environment above 80 decibels, the number of deaf people can reach 50%. Medical experts believe that family noise is one of the reasons for children's deafness. Noise is more harmful to children's physical and mental health. Because children are immature, tissues and organs are delicate and fragile. Whether it is a fetus or a newborn child in the body, noise will damage the hearing organs, leading to hearing loss or loss. According to statistics, there are more than 70 million deaf people in the world today, and a considerable part of them are caused by noise. Expert research has proved that indoor noise is the main cause of children's deafness. If you live in noise above 85 decibels, the deaf can reach 5%. (3) the damage of noise to vision. People only know that noise affects hearing, in fact, noise also affects vision. Experiments show that when the noise intensity reaches 90 decibels, the sensitivity of human visual cells decreases and the reaction time to identify weak light is prolonged. When the noise reaches 95 decibels, 40% people have dilated pupils and blurred vision; When the noise reaches 1 15 shellfish, the adaptation of most people's eyeballs to light brightness is weakened to varying degrees. Therefore, people who are exposed to noise for a long time are prone to eye fatigue, eye pain, dizziness and tears. At the same time, noise can also make color vision and visual field abnormal. It is found that noise reduces the visual field of red, blue and white by 80%. (3) Physiological effects on human body Noise is a malignant substance, which acts on human central nervous system for a long time, causing imbalance of excitation and inhibition of cerebral cortex, abnormal conditioned reflex, dizziness, headache, tinnitus, dreaminess, insomnia and other symptoms. Palpitation, memory loss, inattention and other symptoms. In severe cases, it will lead to insanity. This kind of symptoms, the curative effect of drug treatment is very poor, but when out of the noise environment, the symptoms will be significantly improved. Noise can cause dysfunction of autonomic nervous system, which is manifested as increase or decrease of blood pressure, change of heart rate and aggravation of heart disease. Noise will reduce the secretion of saliva and gastric juice, reduce gastric acid, weaken gastric peristalsis, lose appetite and cause gastric ulcer. Noise will also have an impact on human endocrine function, such as: leading to female sexual dysfunction, menstrual disorder, increased abortion rate and so on. Noise also has a negative impact on children's intellectual development. According to the survey, children living in 75 decibel noise environment before the age of 3 will suffer different degrees of damage to their heart and brain function development. Children living in a noisy environment are 20% less intelligent than children living in a quiet environment. The psychological impact of noise on people is mainly to make people anxious, excited, fidgety and even lose their minds. In addition, noise is harmful to animals and buildings, and plants under noise do not grow well, and some even die. ① Damage to cardiovascular system. Noise is a risk factor for cardiovascular diseases, which will accelerate heart aging and increase the incidence of myocardial infarction. Medical experts have proved through human and animal experiments that long-term exposure to noise will increase adrenal secretion in the body, thus raising blood pressure. People who live in noise with an average of 70 decibels for a long time can increase the incidence of myocardial infarction by about 30%, especially at night. The survey found that the myocardial infarction rate of residents living beside the expressway increased by about 30%. 110/textile female workers were investigated. The incidence of hypertension was 7.2%, of which the contact intensity reached 100 dB noise, and the incidence of hypertension reached 15.2%. ② Damage to female physiological function. Women are threatened by noise, and there will be irregular menstruation, miscarriage, premature delivery, etc., such as causing female sexual dysfunction, menstrual disorder, and increased abortion rate. Experts conducted a three-year systematic investigation in seven regions, including Harbin, Beijing and Changchun, and found that noise can not only make female workers suffer from noise deafness, but also have a negative impact on their menstruation and fertility. In addition, it can also lead to miscarriage, premature delivery and even teratogenesis. Foreign countries have made a survey on the common situation of miscarriage and premature delivery of pregnant women in a certain area, and found that they live near an airport, and the culprit is the huge noise generated when the plane flies and lands. ③ Noise can also cause nervous system dysfunction, mental disorder, endocrine disorder, and even increase the accident rate. Noisy working environment can lead to dizziness, headache, insomnia, dreaminess, general fatigue, memory loss, fear, irritability, inferiority and even insanity. In Japan, there have been cases in which someone went insane because he couldn't stand the noise of the train and finally committed suicide.
