The disadvantages of technological development. Urgent! Technological development can do more harm t

1. Mobile phone separation anxiety disorder:

An experiment done by psychologists at the University of Essex in the United Kingdom confirmed that mobile phone separation anxiety disorder affects more and more young people. As soon as they are not with their phones, they immediately show symptoms of anxiety and distraction, which are very similar to gambling addiction.

2. Computer vision syndrome:

Prolonged staring at a computer screen can easily lead to computer vision syndrome, with the main symptoms including: eye strain, blurred vision, and headaches. To alleviate these problems, it's best to reduce screen time, blink often, and do eye exercises to give your eyes plenty of rest.

3. Mouse hand:

Excessive computer use and frequent mouse operation can easily lead to tendonitis of the hand (commonly known as "mouse hand"), and the main symptoms are tingling and numbness. In such cases, in addition to using less computers, getting enough rest, and receiving physiotherapy if necessary**.

4. Mobile elbow:

Elbow is medically known as "cubital tunnel syndrome", which is characterized by tiredness, numbness, and pain in the elbow joint, and the inability to lift the arm in the early stage. The main reason is that after using the mobile phone for a long time, the flexing tendons of the elbow are too tense, resulting in damage to the nerves in the arm. When talking on your phone for a long time, it is best to use hands-free, or use headphones.

5. Motion sickness:

Facing the screen of digital products for a long time can easily lead to dizziness and nausea, which is called "screen sickness". Some people also get dizzy when browsing quickly on their phones. The reason for this is that the moving content on the screen can make the user feel dizzy and nauseous as if they were on a bumpy ship on the sea.

6. Carpal tunnel syndrome:

A new study published in the American journal Muscles and Nerves found that people who use smartphones, tablets or game consoles for long periods of time (at least 9 hours a day) are more likely to experience skeletal muscle pain and discomfort in the wrist and hand. This condition is called carpal tunnel syndrome, and its clinical manifestations mainly include: numbness, burning pain in the index finger, middle finger, and ring finger of the median nerve, which worsens at night and even affects sleep.

Dear teachers and students:

Hello. The pros and cons of technological development have now become a topic that everyone pays attention to. Before I give my opinion, I would like to make a comparison:

In ancient times, people were superstitious about ghosts and gods, believing that people's lives were determined by heaven, and that birth, old age, sickness and death were controlled by heaven;

In modern times, through the development of science and technology, people have proved that superstitious ideas are not advisable, and they have to create their own lives with their own hands.

In ancient times, many people fell seriously ill, and doctors could do nothing but watch the sick die in agony.

But now, through the development of science and technology, most of the incurable diseases have been successful, and people don't have to worry about getting sick.

In ancient times, communication was very inconvenient, and even when someone in the family died, the wanderer in another country would have to wait for more than a month to know;

But nowadays, communication has become very fast and convenient. Mobile phones, television, newspapers, e-mail, etc., have become a new way to bring people closer together.

These examples are just the tip of the iceberg of how technology has developed for the benefit of humanity. Technology is developing so rapidly that ancient people could not have imagined. Why do TV and newspapers say almost every day that we should advocate the development of science and technology, because how did the thousand-year-old dream of flying come true?

It is the development of science and technology; What is the reason for the ease of communication? It is the development of science and technology; How can a seriously ill person be able to live happily ever after? It is the development of science and technology;

If the development of science and technology is wrong, then why did inventors and scientists such as Galileo, Newton, Edison, Marie Curie, and Einstein dedicate their precious lives to science? Why spend so much precious time on "wrong" causes? Are they incapable of judgment?

Who thinks that their deaths are worthless, and who thinks that there is no point in dedicating their lives to science?

Of course, the development of science and technology has also caused certain negative effects, but these effects should be very small, but human beings are like a magnifying glass, magnifying these negative effects. If humans could consciously reuse plastic bags instead of throwing them away, would it cause such serious white pollution? If human beings can exhaustively exploit resources, will it cause the current shortage of resources?

If humans can save water and factories don't discharge sewage in violation of regulations, will it cause the current severe water shortage? There are many other things like this going on, and some people are not only not introspective, but blindly point the blame to "technology". I feel ridiculous and hopelessly incorrigible for these people.

I can't help but ask: Isn't the development of science and technology necessary for society and mankind?

The way humans lived, 200,000 years ago.
