With the development of the Internet, there are 84 million netizens in China, including165,000 minors under the age of 8, accounting for 19%, and 14.8% of the165,000 minors, that is, 2.44 million. They not only fell in love with the Internet, but also fell in love with it. According to international standards, this is called "Internet addiction syndrome" (IAD for short). Its basic "symptom" is that online time is out of control and it is difficult to extricate itself. They may not eat or sleep, but they must surf the Internet. Even if they realize the seriousness of the problem, they will continue. Often manifested as depression, dizziness, shaking hands, fatigue, loss of appetite and so on. Internet addiction has become the trauma and confusion of many families, and triggered a series of social problems. How to guide people to surf the Internet healthily is an urgent problem for our whole society.
Internet is a "double-edged sword", which not only opens a brand-new cultural space, but also brings new challenges to law and morality, directly affecting people's lifestyle, values and behavior.
In the Internet, the information space is open to everyone and has no absolute authority. People have a strong demand for novelty, fantasy and entertainment. The novelty, virtuality and playfulness of the network just meet people's special psychological needs. Experts point out that if the Internet is used properly, it can bring efficiency and happiness to people's work and life. If used improperly, "virtual world" can sometimes make people lost and even confuse reality and virtual world.
Internet makes people's communication and interaction more open than ever before, but it also implies some new challenges to the past laws and ethics caused by laissez-faire. In all kinds of internet information, there are various toxic cultures lurking, such as the network "black culture" with negative ideological function, the network "pornographic culture" and "violent culture" which exaggerate pornography and violence, all of which bring various negative effects to people.
Experts pointed out that in the process of purifying the internet space and building a healthy and civilized network culture, we should adopt the policy of simultaneous legal construction and moral construction. In a sense, whether the Internet brings people efficiency and happiness or harm and danger lies not in the Internet itself, but in how people grasp and use it.
"In order to resist viruses on the Internet, scientists have invented a' firewall' for antivirus and antivirus. For the social virus of' electronic heroin', it is necessary for the whole society to build a solid' firewall'. "
Healthy surfing the Internet means controlling the content and time of surfing the Internet. At home, colleagues and classmates should also remind each other to be as healthy as possible.
Be good at online learning and don't browse bad information;
Honest and friendly, not insulting and deceiving others;
To enhance self-protection awareness, don't date netizens at will;
It is necessary to maintain network security without disturbing network order;
It should be beneficial to physical and mental health, and we should not indulge in virtual time and space.
Second, good health.
Pay attention to develop good hygiene habits: computer operators should not eat while operating the computer, nor eat in the operation room, otherwise it will easily cause indigestion or gastritis. Touch the computer keyboard too much, wash your hands after work to prevent infectious diseases.
Keep your skin clean: Always keep your face and hands clean, because there is a lot of static electricity on the surface of the computer screen, and the accumulated dust can be transferred to the exposed skin of the operator's face and hands. If you don't pay attention to cleaning for a long time, it will easily lead to ugly macula and pigmentation, and even cause skin lesions in severe cases, affecting beauty and physical and mental health.
Pay attention to supplement nutrition: computer operators working in front of the screen for too long will consume rhodopsin on the retina, which is mainly synthesized by vitamin A. Therefore, computer operators should eat more carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal livers, lean meat and other foods to supplement vitamin A and protein. You can drink more tea at ordinary times, because tea contains active substances such as tea polyphenols, which can absorb and antagonize radioactive substances and protect human cognitive function and heredity to some extent.
Pay attention to the correct posture: the seat should be straight and comfortable when operating. The center of the computer screen should be installed at the same height as the operator's chest, and the distance between the eyes and the screen should be 40-50 cm. It is best to use a chair with adjustable height. During the operation, you should blink or close your eyes for a while frequently to adjust and improve your vision and prevent it from declining.
Pay attention to the working environment: the light in the computer room should be suitable, neither too bright nor too dark, so as to avoid interference caused by direct light irradiation on the fluorescent screen. Regularly remove indoor dust and microorganisms. When cleaning, it is best to disinfect the air filter with a wet cloth or a warm mop, adjust the air volume reasonably, and change the fresh air. If you are doing computer operations at home, you should also try to refer to your heart and use protective screens to minimize the harm of electronic radiation to the human body.
Pay attention to the combination of work and rest: Generally speaking, computer operators should rest for about 1 0 minutes after continuous work. Moreover, it is best to exercise your hands and feet and torso outside the operating room, take a walk, do radio exercises, take the initiative to rest, or do eye exercises, and exercise your head indoors (many people complain about cervical pain, and moving your head will help).
Pay attention to protecting eyesight: To protect eyesight, besides taking regular rest and supplementing foods rich in vitamin A, it is best to pay attention to the distance and do eye exercises regularly to ensure adequate sleep time.
Online female skin care
I used to have good skin, white and tender, without spots. I've been surfing the Internet for a long time recently. ...
MM skin care guide for computers
Today is the world of the Internet, and more and more female netizens surf the Internet, and the time is getting longer and longer. In foreign countries, the number of women surfing the Internet has surpassed that of men for the first time to become the main force. However, during your happy close contact with the Internet, do you know the potential harm of electromagnetic radiation to your face?
Facial protection
Although the harm of surfing the Internet to the appearance of female netizens is not an enemy, the power of electromagnetic radiation cannot be underestimated. In the survey, a female netizen said: "I used to have a good skin, white and tender, with no spots at all." Recently, I have been surfing the Internet for a long time, sometimes 7 to 9 hours. I feel dry, peeling and yellow these days. "For female netizens who don't want to give up surfing the Internet and want to keep their skin bright, this has become a prominent problem.
Screen radiation produces static electricity, which is the easiest to absorb dust. Face to face for a long time is more likely to lead to spots and wrinkles. Therefore, before surfing the Internet, you may wish to apply skin care lotion and add a layer of calomel to increase the skin's resistance.
Thoroughly clean the skin
After surfing the internet, the first task is to clean the skin. Wash your face thoroughly with warm water and cleansing liquid, wash away all the dust and dirt adsorbed by static electricity, and then apply mild skin care products. Long-term use can reduce injuries, moisturize and beautify. This is really a pay and a gain for women who surf the Internet.
Keep bright eyes.
If you don't want to see a person with red eyes, haggard face and dark circles the next day, then don't fight continuously for a long time, especially don't stay up late surfing the Internet. Prepare a bottle of eye drops at ordinary times in case of emergency. It is also good to apply a slice of cucumber, potato chips or frozen milk and cold dishes after surfing the Internet. The method is: slice cucumber or potato, apply it to double eyelids, close your eyes and rest for a few minutes; Or use gauze to soak frozen milk herbal tea and apply it to eyes, which can relieve eye fatigue and nourish skin around eyes.
Increase nutrition
It is very important to increase nutrition for people who often surf the Internet. Vitamin B is very beneficial to mental workers. If you go to bed late, the quality of your sleep is not good. You should eat more animal livers and fresh fruits and vegetables, which are rich in vitamin B. In addition, meat, fish and dairy products also help to increase memory; Chocolate, wheat doughnuts, seafood and dried fruits can enhance the coordination of the nervous system and are the best snacks when surfing the Internet.
Drinking Lycium barbarum juice and carrot juice from time to time is also very effective for eye care and skin care. If you are very concerned about your appearance, drink carrot juice or freshly squeezed juice.
Do gymnastics often to get rid of fatigue.
After surfing the Internet for a long time, you may feel dizzy, stiff fingers, backache, and even edema and varicose veins of lower limbs. Therefore, we should do more gymnastics at ordinary times and maintain vigorous energy.
For example, lie flat on the bed before going to bed, relax the whole body, and put your head back below the edge of the bed with the back of your head to alleviate the lack of blood supply and oxygen supply to the brain; Raise your feet and lie flat on the bed or sofa to reduce foot edema, help blood return and prevent varicose veins of lower limbs; Stretch from time to time during surfing the internet, stretch your muscles or lean on a chair, push your hands back, and stretch your tense and tired waist muscles; You can also shake your fingers, which is the easiest way to completely relax your fingers. Remember, this kind of gymnastics does not exercise much, but it is far more effective than sleeping late.
