Internet addiction is not good for teenagers, especially students who waste money in a panic and waste their studies, and may even go astray.

There is harm in surfing the Internet for a long time, and it is okay to play for a while. A small number of times.

Every day will make you want to go online every day without wanting to work.

a. Eye diseases: the brightness of the computer screen is high, and the picture often beats, if the user stares at the screen for a long time, it will make the eyes overtired, causing myopia in the light, and causing retinal detachment and even blindness in the heavy.

b. Cervical spondylosis, lumbar strain, frozen shoulder and other lesions: do not leave the grid overnight, and the shoulder should be laid off. People who work at their desks for long periods of time or are immersed in computers are more likely to develop frozen shoulder, especially in summer.

d. If you use the Internet for a long time in an environment with poor ventilation and sanitary conditions or in an air-conditioned room, heat cold, gastrointestinal diseases, contact dermatitis, dizziness, swelling and headache are common symptoms.

1. Damage to the eyes.

Staring at electronic products for a long time can easily lead to excessive eye use, cause eye fatigue, reduce vision, and in severe cases, lead to retinal detachment, and may face eye diseases such as glaucoma and presbyopia.

In particular, children's vision is unstable and may accelerate myopia. There are many young office workers, after working on the computer during the day, they still "keep the machine in hand" at night, use their mobile phones to brush short**, watch movies, watch**, etc., and even turn off the lights before going to bed and surf the Internet. I often wake up the next day with uncomfortable symptoms such as tears, vision loss, and dizziness.

2. Affect mental state.

Usually when we are online, we often underestimate the passage of time, when we keep our eyes on electronic products for 30 minutes to 1 hour, our concentration will begin to decline, and we need to rest for 15 to 20 minutes to regain concentration. Spending too much time online will also affect your studies and work, and you will have to spend more time on to-do lists, and once you can't complete your goals on time, you will accumulate negative emotions such as nervousness, anxiety, depression, and irritability. It can also interfere with sleep and cause social skills to deteriorate.

At present, there are many people who develop a bad posture when using 3C products. For example, when using the computer, the body bends forward, looks at the mobile phone and likes to bow the head, or reclines on the sofa to watch TV, play with the mobile phone, etc., over time, it is easy to lead to spinal joint injury, lumbar muscle strain, body destruction, and various cervical spondylosis due to poor posture.

4. Affect social activities.

Bad Internet habits are most likely to lead to the phenomenon of "crowding out", that is, users spend their precious time and energy on the Internet every day, but crowd out other important activities in life, such as diet and nutrition, sleep and rest, physical exercise, work and study, speech and communication, emotional exchange, etc., day after day, which will eventually affect physical and mental health and endanger interpersonal relationships.

Long-term Internet access to the human body includes headaches, palpitations, loss of appetite, muscle aches and other symptoms. Mental harms include:

It makes people feel social isolation and frustration, loneliness, pessimism and other psychology. Therefore, it is necessary to spend a reasonable amount of time online, and do not delay work, study or other normal life because of the Internet. Arrange your time reasonably, don't indulge in the Internet, and pay attention to distinguishing right from wrong to avoid the impact of bad information.

It must be very harmful to the eyes, and it is also harmful to the body when surfing the Internet regularly.

The main reason is that opinions and information on the Internet spread quickly and widely, which has an unintentional impact on Internet users.

This allows Internet communication to amplify the influence of negative information, such as fertility issues, and strengthen the awareness of the cost and burden of childbearing, which in turn has a negative impact on individual fertility intentions. Theoretically, the Internet itself is not enough to directly affect the fertility concepts and behaviors of netizens. Because the information on the Internet presents a variety of faces, of course, there is also some information that is not friendly to fertility and does not encourage childbirth.

For example, the phenomenon of unmarriage, the surplus of men and women, the single population and the economy, the Dink family, the rising divorce rate, the involution of education, and the high cost of raising children all seem to point to the general trend of low fertility. Under the influence of the low fertility culture on the Internet for a long time, netizens will be imperceptibly affected by the concept of low fertility. Behind the chic Dink culture, to a certain extent, people's emotional expression of fertility anxiety and active avoidance of fertility pressure are the manifestations of the decline in fertility confidence index.

However, correlation is not the same as causation. When applying cross-sectional data analysis, special care should be taken with regard to the relationship between variables, and it is difficult to make causal inferences without a forward and backward connection. Empirical analysis should be preceded by logical qualitative analysis.

This data and conclusions are also questionable and discussable.

Today, there are almost no young people who do not have access to the Internet, except for some people with disabilities who do not have access to the Internet or older people who have difficulty crossing the "digital divide". Perhaps, first of all, is there a comparable number of residents and non-users of the Internet? Is it statistically reasonable?

The nature of the group of people who do not use it, whether it is old or young, contains endless possibilities. Social science is characterized by ambiguity, and excessive pursuit of precision will miss its essence and make people lose the point. It is also worth paying attention to the demographic characteristics and fertility attitudes of netizens, and it is important to know that the heterogeneity of netizens is extremely large.

For people who have completed the task of childbearing, the Internet will naturally not affect their conception of childbearing; For those who are not yet married, childbearing is also the next step; For those who are married and have not yet had children, information about fertility on the Internet may affect their attitudes and confidence in childbirth.
