Anonymous users2024-02-06One is that the computer itself will directly affect people's physical health. Computer monitors use electron guns to emit electron beams to produce images, accompanied by electromagnetic waves and radiation, long-term fixation can cause visual fatigue, and at the same time, screen glare and flickering can also damage the eyes, which can lead to temporary myopia and secondary headaches. When operating the computer, the body posture rarely changes, and the movements are fast and single.
1. Repetition can easily lead to diseases of the musculoskeletal system. The keys on the keyboard are densely packed, and prolonged keystrokes can cause damage to the fingers and upper limbs. The second is the harm of computer microwaves to the body.
The low-frequency electromagnetic radiation and low-energy X-rays of computers can easily cause central nervous system disorders. A UK study of electromagnetic waves in the office confirmed that magnetic fields and low-frequency radiation emitted by computer screens can cause 19 conditions, including itchy eyes, temporary memory loss, irritability, depression, etc. It is also easy to cause abnormal reproductive function and embryonic development in women.
Third, the gas emitted by the computer harms the respiratory system. Researchers from the British Allergy Society** believe that office equipment will release more or less ozone that is harmful to human health, and the office equipment here mainly refers to computers, laser printers, etc., these ozone gas is not only toxic, but also may cause some people to have difficulty breathing, for allergy and asthma patients, the situation is more serious. If you stay in a place with a high concentration of ozone gas for a long time, it can also cause lung lesions.
Fourth, it increases mental and psychological pressure. In the process of operating the computer, the attention is highly concentrated, and the eyes and fingers move quickly and frequently, which makes the physiological and psychological burden excessive, resulting in neurasthenia, head soreness, dreams, decreased body immunity, and even induces some mental diseases.

Glasses can hurt, probably due to a high concentration for long periods of time (both games require a lot of reflexes, don't they?). If you can't wait until you're done to take measures after playing, you should consciously do eye exercises every 1 hour or so (never be lazy), close your eyes and rest for a while, and take eye drops every day to soothe your eye nerves.
At the end of the day, it's that you play too much every day. I'm also an otaku, but I pay attention to controlling the time I spend playing with the computer every day, no more than 5 hours, try to use full screen when watching movies and TV series, and then move the seat farther away.
When you have free time (such as when you lie down and still haven't fallen asleep), you can ask yourself what you played today, what would happen if you played less or not at all, and what would happen if you kept playing or didn't play in the future. If you can understand the true value of playing a game, you won't be held back by it, and you can make it a great addition to your life.

The main component of monosodium glutamate is monosodium glutamate, which can be broken down during digestion, which is catalyzed by enzymes in brain tissue and can be converted into an inhibitory neurotransmitter. When excessive intake of MSG, this inhibitory neurotransmitter will inhibit various nerve functions in the human body, resulting in a series of symptoms such as dizziness, headache, drowsiness, muscle spasms, etc. In particular, glutamate can combine with zinc in the blood to produce zinc glutamate that cannot be used and is excreted from the body, resulting in zinc deficiency in the human body, so it is recommended not to consume too much monosodium glutamate.
