In fact, Internet cafes only provide a place for everyone to surf the Internet, so the Internet cafes themselves are harmless. It's just that Internet cafes are generally run by some black-hearted bosses, so they become harmful. The following are some recognized dangers. First of all, destroy the body. Internet cafes have mixed air, high population density and complete smell of smoke, vegetables, sweat and odor. The noise of machines, slapstick and swearing is harsh, and the sanitary environment is extremely poor, which seriously affects health. Therefore, when the internet addicts who play all-night video games walk out of the internet bar, their eyes are red, unkempt and their legs are weak, and they look like white mustard. This is the time when our young students grow up. If we don't know hunger and thirst, staying in Internet cafes day and night will do no less harm to our health than marijuana, white powder and other drugs. This is not an alarmist. Second, psychological harm. Internet addicts have a strong psychological dependence on the internet, which may affect their study and health, and may lead to psychological abnormality and mentality distortion in severe cases. The purpose of surfing the Internet is to adjust the mentality. The school has a heavy academic burden and great psychological pressure. If we can find a loyal audience (not necessarily a friend) to chat online, our mood will be relaxed and stable. We don't deny this statement. If we grasp the harmony, it will be beneficial to adjust our mentality. But in fact, once online, many minors can't master it. Spending too much time and energy in Internet cafes will affect their study, make teachers criticize, and make parents angry, but the psychological burden will be heavier. Third, make trouble. Most of the people who go in and out of Internet cafes are primary and secondary school students, ranging in age from a few years old to seventeen or eighteen. Most of them have no income. In order to get the money into the internet cafe, some gang up to extort money, and some steal it. There is also a person who goes in and out of Internet cafes. They simply blackmail primary and secondary school students, and there are often fights in Internet cafes. This shows that Internet cafes have become a big gathering place for trouble. Fourth, it affects your studies. I remember reading the voice of an online fan in the newspaper: Damn Internet cafe, you took away my studies and my university. I gnash my teeth and feel distressed! But I just can't help myself! The classmate said: I saw the keyboard as soon as I closed my eyes. When my fingers touch anything, I feel like a mouse. When I click the mouse, the missile will be launched. We can't really go into the inner world of those internet addicts to understand their feelings, but we can imagine their eyes drifting, their eyes reddening and their psychological exhaustion. How much energy do you have to study? Fifth, security risks. Most Internet cafes don't ask professionals to install equipment, and they don't get permission from the departments of fire control, safety supervision, culture and health. The density of computers in its business premises, computer wiring, safety exits, etc. There are different degrees of problems, and most internet cafes only have one door to enter and exit, and there are no safe passages and guiding signs.
