What are the dangers of chatting online for a long time?

With the continuous progress of society, we have unknowingly entered the information age. Computers: I believe they are already very familiar in people's hearts. It not only promotes human beings and brings social progress, but also provides us with a large amount of spiritual food and material wealth. But what many friends don’t know is that while it brings us countless wealth, it is also quietly causing great harm to our physical and mental health. It is mainly manifested in the following aspects: 1. Microwave hazards: Low-energy X-rays and low-frequency electromagnetic radiation from computers can cause central nervous system disorders. A British study confirmed that low-frequency radiation and magnetic fields emitted by computer screens can cause 7 to 19 kinds of symptoms, including runny nose, itchy eyes, neck and back pain, temporary amnesia, irritability, and depression. For women, symptoms such as dysmenorrhea and prolonged menstruation may also occur, and a small number of expectant mothers may also suffer from premature birth or miscarriage. In addition, long-term computer work results in mental stress, high psychological pressure, and general fatigue. Coupled with electromagnetic radiation, the incidence of breast cancer in female operators is about 30% higher than that of the average person. Relevant studies have also found that electromagnetic radiation from computers can cause cancer; and with the popularity of computers and the Internet, a new modern disease called "computer syndrome" will cause those who have been engaged in computer operation and programming for a long time. Central nervous system disorders cause headaches, insomnia, palpitations, anorexia, nausea, depression, slow thinking, irritability, and frequent fatigue. The best way to protect your computer from microwaves is to keep a distance from it. The safest way to place it is to place the "back brain" of your computer against the wall, with the distance between each computer at least 1 meter. If there is really no space, the distance between the person and the "back head" of the computer should be kept at more than 1 meter. If the time on the plane is too long, leave for 15 to 30 minutes every 1 to 2 hours, stand up, take a break, look out the window, and breathe fresh air. Drink more tea. The active substances such as tea polyphenols in tea are beneficial to absorbing and resisting radioactive substances. 2. Vision hazards: The eyes are most vulnerable to damage when using computers, especially myopia and ciliary muscle spasm in teenagers. Known as "computer vision syndrome," these conditions are a stress disorder caused by staring at one spot for long periods of time and blinking only one-third as often as usual, reducing the secretion of lubricants in the eyes. If this happens for a long time, it will not only cause eye fatigue, double images, blurred vision, but also cause other uncomfortable reactions. You should blink more often in front of the screen to increase tear gland secretion and moisturize your eyes. The most effective method is to rest properly and eat more foods containing vitamin A to supplement the rhodopsin on the retina, such as carrots, cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat, etc. 3. Tissue damage: Repeated and tense movements when operating a computer can damage muscles, nerves, joints, tendons and other tissues in certain parts. In addition to back pain, people suffering from carpal tunnel syndrome may experience wrist pain or even numbness, with these symptoms extending to the palms and fingers. More exercise is the most effective way to overcome this computer occupational disease. The amount of exercise does not need to be too large. Walking, lifting dumbbells and light aerobic exercise can all achieve good results. The important thing is to persevere. Change your position frequently and avoid working in the same position for long periods of time. Adjust tables and chairs to a height that suits you. The correct height should be: when sitting on a chair, the line between your elbows and the keyboard should be parallel to the ground. The computer screen should be placed slightly lower than your line of sight. Make sure your neck is slightly tilted upward when looking at the screen and avoid looking up; Your feet should be flat on the ground, the chair should be stable, and your back should feel comfortable. 4. Respiratory system hazard: The gas emitted by the computer can harm the respiratory system. A recent research report published by researchers from the British Allergy Foundation pointed out that office equipment can release ozone gas that is harmful to human health. The main culprits are computers, laser printers, etc. Not only are these ozone gases toxic, they can also cause breathing difficulties for some people. For those with asthma and allergies, the situation is even more serious. In addition, staying in places with high ozone gas concentrations for a long time can also cause lung disease. The computer room should frequently open doors and windows for ventilation, and place a small air freshener or green plants near your seat to improve indoor air quality. The printer will also produce irritating gases that can irritate the nose and trachea. Prolonged contact should be avoided as much as possible. Drinking green tea can prevent computer radiation: Computer radiation not only harms people's health, but also affects the quality and efficiency of work.

For people who live a stressful and busy life, the easiest way to resist computer radiation is to drink 2 to 3 cups of green tea and eat an orange every morning. Tea is rich in provitamin A, which can be quickly converted into vitamin A after being absorbed by the body. Vitamin A can not only synthesize rhodopsin, but also enable the eyes to see things more clearly in dark light. Therefore, green tea can not only eliminate the harm of computer radiation, but also protect and improve vision. If you are not used to drinking green tea, chrysanthemum tea can also play a role in resisting computer radiation and regulating body functions. Help you reduce computer radiation: Technicians said that computer radiation is inevitable, but it can be reduced. First of all, you should try to buy a new computer as much as possible. Generally, do not use old computers. The radiation of old computers is generally more severe. Under the conditions of the same distance and the same model, the radiation is generally 1-2 times that of a new computer. When operating a computer, it is best to install a computer-specific color filter on the display screen to reduce the harm of radiation. Do not place stray metal objects indoors to avoid re-emission of electromagnetic waves. When using a computer, you must adjust the brightness of the screen. Generally speaking, the brighter the screen, the stronger the electromagnetic radiation, and vice versa. However, it should not be adjusted too dark, so as not to affect the effect due to too low brightness and easily cause eye fatigue. Also be sure to keep an appropriate distance from the screen. The closer you are to the screen, the greater the electromagnetic radiation the human body will receive, so it is better to be half a meter away from the screen. Computer radiation damages the skin, so you must wash your face after using the computer: Computers are increasingly becoming a necessity for work. Dermatologists recently reminded that when using computers on a daily basis, you must wash your face after using the computer. The distance between the body and the computer screen should be kept at least 70 cm as much as possible. Although the amount of radiation generated by computer screens is very small, it can still damage the skin over time, easily causing facial spots, sagging skin around the eyes, crow's feet, eye bags, and dark circles. Experts from the Municipal Dermatology Hospital remind frequent computer users, especially women, that it is best to apply some protective products, such as isolation cream or foundation, before getting on the computer. At the same time, it is best to use a computer screen protector. After using the computer, it is best to wash your face frequently. Because you spend a long time in front of the screen, your skin is prone to excessive oil secretion, dust accumulation, etc. Before going to bed and after using the computer, you need to clean your skin in time. The greatest damage caused by computer radiation occurs on the keyboard: Do you often feel a heavy head or memory loss? When sleeping on your stomach, remember to turn off the computer, not just the screen. Because just turning off the screen cannot eliminate radiation, and we all sleep on our stomachs with our heads directly facing the computer. If we get Alzheimer's disease or a brain tumor one day, it will be too late. With the continuous progress of society, we have unknowingly entered the information age.
