Let's take a look at the relevant knowledge and understand its harm.

A sedentary lifestyle can cause back pain

If you sit for a long time, your muscles will not have the opportunity to stretch and contract, and you will have back pain in the long run, resulting in repetitive mechanical movement injuries. Many people are accustomed to sitting in front of a computer for long periods of time for work or play. Medical experts warn that excessive computer use can have adverse effects on people's health.

Two commonly used mice will have stiff fingers

Long-term use of computer keyboards and mice can be linked to a condition called wrist syndrome, which can lead to pain in the index or middle finger, numbness and weakness of the thumb muscles, which can lead to nerve damage and muscle weakness in the hand. The problem lies in the repetitive typing on the keyboard or moving the mouse every day, and the long-term, intensive, repetitive, and excessive movement of the wrist joints, resulting in peripheral nerve damage or compression, so that nerve conduction is blocked, resulting in impaired sensation and movement of the palm. In addition, the elbow is often lower than the wrist, and the hand is held high, and the nerves and tendons are often compressed, and the hand will begin to numb, the fingers will lose flexibility, and there will often be joint pain.

Frequent finger exertion can also damage the nerves and muscles of the hand and related parts due to excessive fatigue, resulting in a series of symptoms such as numbness due to ischemia and hypoxia.

3. Exposure to electromagnetic radiation will cause insomnia

If the display is too hot, there will be quite a lot of it when working'Electromagnetic radiation, which ionizes the air, constantly generates a positive charge (positive ions), and constantly neutralizes with the negative ions of the air, resulting in an almost zero amount of negative ions. Negative ions are more beneficial, positive ions are more harmful, long-term in the environment with too many positive ions, they enter the lungs through breathing, and then are transported to various tissues of the human body with blood circulation, so that people's blood and body fluids are acidic, delay the normal metabolic function of the body, so that toxins are hoarded in the body, make people insomnia, reduce immunity, and women may also have endocrine disorders.

After the above introduction, I believe that everyone will have a deeper understanding of what are the dangers of computer disease, we recommend not to sit in front of the computer for a long time, should go outside to move your muscles and bones, and look at the green scenery in the distance, which is also good for our eyes, and we should take appropriate measures to reduce the damage of the computer to us.
