if it is a computer, you need to choose a high-quality chassis for radiation protection. The metal plate should be thick and the cooling holes should not be opened too much. The display is replaced by LCD.
then choose a good quality mouse and keyboard. Because they emit more radiation than your monitor. It is also the closest equipment to the human body.
then pay attention to indoor cleaning. Dust is also one of the culprits for absorbing and diffusing radiation. Especially near the computer. Will be absorbed by the machine.
The role of plants, especially cactus and aloe, has been exaggerated by the public. This erroneous view has been clarified in CCTV's earlier programs. Experiments show that cactus has no ability to resist radiation and absorb radiation.
And this spiny plant has been listed as unsuitable for indoor placement by Feng Shui experts.
This is like saying that plants can purify the air, and two pots of ivy can eliminate formaldehyde in 15 square rooms. But you can't get rid of formaldehyde even if you cover the newly decorated room with plants.
controlling the source is the key.

The following is quoted by others:
In office, the computer is our most important office supplies. It is hard to imagine how we would work without it. But unfortunately, while we enjoy all the convenience brought by the computer, we have to accept its threat to our health both physically and mentally. Therefore, it is urgent for us to understand the computer "disease" and prevent it. In order to fully understand the negative impact of computers on OL's body and mind, we specially organized this plan to comprehensively introduce the tips and methods to alleviate the eight computer "diseases" that OL is most difficult to escape.
count 1: electromagnetic radiation
symptoms: insomnia, endocrine disorder
cause of disease: when the monitor is too hot, there will be quite a lot of electromagnetic radiation at work, which will ionize the air, constantly produce positive charges (positive ions), and constantly neutralize with negative ions in the air, resulting in almost zero negative ion content. The more beneficial negative ions are, the more harmful positive ions are. In the environment with too many positive ions for a long time, they enter the lungs through breathing, and then they are transported to various tissues of the human body with blood circulation, making people's blood and body fluids acidic, delaying the normal metabolic function of the body and accumulating toxins in the body. Causes insomnia, decreased immunity, female endocrine disorders, etc.
mitigation methods
1. Clean the office environment carefully. Because positive ions will be firmly adsorbed on dust particles, the more dust, the more positive ions.
2. drink more tea. Tea polyphenols and other active substances contained in tea help to absorb radioactive substances.
3. Most of the radiation emitted by the display does not come from its front, but from its sides and back. Therefore, don't point the back of your monitor at the back of your colleague's head or the side of your body.
4. Always drink green tea. Green tea is the most talked about health drink in recent years, because it contains powerful antioxidants catechol and vitamin C, which can not only eliminate free radicals in the body, but also make the accessory kidney cortex secrete hormones against stress, which greatly improves the mood. However, it is best to drink it during the day to avoid affecting sleep.
5. Mung bean can clear away heat and toxic materials, induce diuresis and reduce swelling, while Coix seed can strengthen the spleen and relieve diarrhea, lighten the body and replenish qi, which is very helpful to eliminate irritability when you often need to work late or get upset, dry mouth and constipation.
6. Washing your face frequently can prevent the skin from being stimulated by radiation waves.
7. Put a pot of plants or water under the computer desk to absorb the electromagnetic waves emitted by the computer.
8. Try to use LCD monitors.
9. wear a radiation-proof Chinese-style chest covering.
count 2: dust field
symptoms: skin allergy
cause of disease: an electrostatic field will be formed around the monitor in the turned-on state, which will almost suck the dust suspended in the air of the whole room into its own field, thus stimulating the facial skin and causing allergic rash. Sitting in front of the computer, your surroundings are filled with air containing a lot of dust particles, so the user's skin is very prone to allergic phenomena such as rash.
mitigation methods
1. Don't put mountains of papers and documents around the computer, but put all the necessary documents into the cabinet in different categories, because the dust on papers and documents is usually difficult to clean.
2. Wipe the surface of the computer desk with a wet cloth dipped in antistatic agent.
3. Always open the window for ventilation.
4. Rub some moisturizing cream on your face before using the computer, or soak a towel with chamomile extract (a simpler way is to use a wet chamomile tea bag) and apply it directly to your forehead and cheeks.
5. Put a pot of cactus on the computer desk, because the acupuncture of cactus can absorb dust.
6. Clean the keyboard frequently. Wash your hands before eating when using the keyboard and after using it. Cover the keyboard with a cloth when not in use. Because the keyboard is uneven, it is very easy to accumulate dust, and it will become a hiding place for skin diseases and cold germs.
count 3: the picture flickers and gives off heat, which causes the environment to be dry
Symptoms: dry eye
Cause: Although it can't be seen by naked eyes, the picture on the monitor actually flickers all the time. When looking at the monitor, we often stare at a certain point for a long time and rarely blink, so the eye muscles are easy to get tired, the eye mucosa is dry, and the eyes are red, inflamed and painful. After working in front of the computer for 4 hours without interruption, almost everyone's eyes will feel sore and trachoma. The working environment of computer workers is closed, the humidity in the environment is low, and the computer constantly emits heat. In a dry environment, the tear layer evaporates in a few seconds, which has become an important cause of dry eye.
mitigation methods
1. It needs to be more than 7cm away from the monitor, and the placement position should be slightly lower than the line of sight of both eyes, so as to minimize the area of eyeball exposed to air.
2. adjust the brightness to a level that will not make your eyes tired.
3. When working in front of the computer, the room should be neither too dark nor too bright. The ideal office environment is that the brightness of the room is the same as that of the screen.
4. To avoid the images of your face, lights and objects appearing on the screen (all light and shadow will make your eyes twice tired), so avoid the indoor light directly shining on the screen and causing interference light. The light source should preferably come from the left or right of the computer user. If you wear glasses, you should get yourself a pair of lenses with anti-reflective coating.
5. In order to prevent dry conjunctiva, drop some eye drops with the same composition as our tears when using the computer.
6. When eyes are tired, applying a wet towel boiled with light black tea for a few minutes will quickly eliminate congestion and fatigue.
7. fry 5g of black beans, cool them and grind them into powder. 5 grams of walnut kernel, stir-fry slightly to remove clothes, and mash it like mud after cooling. Take 1 spoon of each of the above two foods, pour into 1 cup of boiled milk, add 1 spoon of honey, and take it in the morning or after breakfast. It can enhance intraocular muscle strength, strengthen adjustment function and improve the symptoms of eye fatigue.
Count 4: Long-term use of mouse
Symptoms: Mouse hand (wrist joint syndrome)
Cause of disease: Long-term use of computer keyboard and mouse may be linked to a disease called wrist joint syndrome, resulting in pain and numbness of index finger or middle finger and muscle weakness of thumb, which may lead to nerve damage and muscle atrophy of hand. The problem is that typing on the keyboard or moving the mouse repeatedly every day, the wrist joints are long-term, dense, repeated and excessively active, which leads to peripheral nerve injury or oppression, which blocks nerve conduction, thus causing obstacles in the feeling 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 start to numb, the fingers will lose flexibility, and joint pain will often occur. Frequent exertion of fingers will also damage the nerves and muscles of hands and related parts due to excessive fatigue, resulting in a series of symptoms such as ischemia and hypoxia and numbness. According to the survey, women have more "mouse hands" than men, because women's wrists are usually smaller than men's, and the median nerve of the wrist is easily oppressed.
Relief methods
1. Try to avoid the upper limbs being in a fixed, mechanical and frequent working state for a long time. When using the mouse or typing, you should get up and move your limbs every hour of work, and do some movements such as clenching fists and pinching fingers to relax your fingers.
2. When using the computer, the height of the keyboard and mouse on the computer desk should be lower than the elbow height when sitting, which is beneficial to reduce the damage to the tendon sheath of the wrist when operating the computer.
3. When using the mouse, don't hang your arm to reduce the pressure on your wrist. Move the mouse by arm instead of wrist to reduce the stress on your wrist.
4. Don't knock the keys of the keyboard and mouse too hard, and it's better to do it easily and moderately.
5. It is best to choose a mouse with large radian, wide contact surface and helpful dispersion.
6. When using the mouse, use the "mouse wrist pad" to pad the wrist.
count 5: impaired brain function
symptoms: memory loss
cause of disease: with the increasing popularity of personal computers, people are suffering from memory loss more and more, mainly because they rely too much on computers, which makes their brain function weaken.
Relief methods
1. Lie flat on the bed before going to bed, relax the whole body, and put your head back below the edge of the bed to relieve the lack of blood supply and oxygen supply to the brain.
2. Ensure adequate sleep. No matter how stressful the work is, 8 hours of sleep every day is essential, and we should try our best to ensure the quality of sleep, so that the blood circulation in the cerebral cortex can be adjusted in time.
3. practice meditation. It is best to have 2-3 minutes to meditate on the relaxing and beautiful things in life every day, listen to the rhythm of your breathing, and let your mood relax as much as possible. The posture is informal, whether sitting or lying down, subject to comfort.
4. Learn to use the five-stroke input method, instead of always using the associative input method of intelligent pinyin. Try not to use the computer to input handwritten words. Even if electronic files are necessary, you can try to use the handwriting board to input words.
5. Change the unhealthy diet structure and eat more brain-nourishing food.
count 6: using incorrect sitting posture for a long time
symptoms: neck, shoulders and waist pain
cause of disease: if you use the computer with your arms held high and your head down, and cross your legs under the table with difficulty, you will feel pain in your back, numbness in your neck and shoulders and inflexible arms after working for one hour. Keep this sitting posture for one to one and a half years, and you can get double chin and cervical joint stiffness.
Relief methods
1. The upper body should keep the neck upright, so that the head can be supported, the shoulders naturally droop, the upper arm is close to the body, and the elbow is bent at 9 degrees. Operate the keyboard or mouse, and try to keep the wrist in a horizontal posture, and the palm center line and forearm center line should be kept in a straight line. The waist of the lower body is straight, the knees are naturally bent at 9 degrees, and the sitting posture with both feet on the ground is maintained.
2. You must choose a desk and chair with ergonomic design, use a special computer chair, and sit on it and follow the "three right angles": the first right angle is formed at the knee under the computer desk, the second right angle is formed at the thigh and back, and the third right angle is formed at the elbow joint. Lean your shoulder blades against the back of the chair, put your shoulders down and keep your chin away from your neck. Eyes looking straight at the center of the computer screen, it is best to have a supportive chair back and armrest, and the height can be adjusted.
3. Flying a kite: When flying a kite, you can hold your chest high and look around, which can maintain the muscle tension of cervical vertebra and spine, keep the elasticity of ligaments and the flexibility of spinal joints, help to enhance bone metabolism and enhance the compensatory function of cervical vertebra and spine, and prevent the degeneration of vertebrae and ligaments. It is really a good method left by our ancestors to prevent and treat cervical spondylosis.
4. Swimming: Because the head is always lifted up when swimming, the neck muscles and waist muscles are exercised, and people do not have any burden in the water, and will not cause any damage to the intervertebral disc, which can be regarded as a relatively comfortable way to exercise the cervical spine.
5. When using the computer, you should rest for 5-1 minutes every hour, do soft exercises or local massage, and at the same time develop regular exercise habits, and carry out lacing and muscle strength training for shoulder, neck and upper limbs to increase softness and muscle strength.
6. The height of the computer should be appropriate. Install the center of the computer screen at the same level as the operator's chest, and it is best to use a chair with adjustable height. There should be enough space to stretch your feet, your knees naturally bend at 9 degrees, and keep your feet on the ground. Don't cross your feet to avoid affecting blood circulation.
7. Keep your eyes at an appropriate distance from the monitor. The eyes and the computer monitor form a slight downward gaze angle on the screen, which can relax the neck muscles.
8. Relaxing gymnastics
A: Basic posture: Before each training movement, stand naturally, with eyes looking straight, feet slightly apart, shoulder width apart, and hands drooping naturally. Relax all over.
B: lean forward and lean back: with your hands akimbo, raise your head and lean back first, and inhale at the same time, looking up at the sky with your eyes, stop for a minute; Then slowly lower your head to the chest position, exhale at the same time, and look at the ground with your eyes. When doing this action, keep your mouth shut, so that your jaw is as close to your chest as possible. After stop for a minute, do it up and down again for 4 times. The essence of the action is: stretch, relax and slow, so as not to feel uncomfortable.
C: Turn left and right: hands akimbo, first slowly turn your head to the left, and inhale into your chest to straighten your right neck, then stop for a minute, then slowly turn to the right, and exhale, and then straighten your left neck, then stop for a minute. Do this repeatedly and alternately for 4 times.
D: lift your shoulders and shrink your neck: before doing exercises, you should stand naturally, with your eyes looking up, your feet slightly apart, parallel to your shoulders, and your hands drooping naturally. When moving, the shoulders are slowly lifted, and the neck is contracted as far as possible. After stop for a minute, the shoulders are slowly relaxed, and the head and neck are naturally extended to restore nature. Then, the shoulders are forced to sink down, and the head and neck are pulled up. After stop for a minute, the shoulders are relaxed and exhale naturally. Pay attention to inhale slowly while stretching your neck, hold your breath when staying, and relax your shoulders and neck as much as possible when loosening your shoulders. After returning to the natural style, do it again four times.
E: Swing left and right: Before doing exercises, stand naturally, with eyes looking straight, feet slightly apart, parallel to shoulders, and hands akimbo. When moving, the head slowly leans to the left, so that the left ear is attached to the left shoulder. After stop for a minute, the head returns to the middle position; Then tilt to the right shoulder, and the right ear should be close to the right shoulder. After stop for a minute, return to the middle position. This swing from side to side is repeated for 4 times. Inhale when your head swings, exhale slowly when you return to the middle position, and relax your shoulders and neck as much as possible when doing exercises. It is better to move slowly and steadily.
count 7: thinking patterns, unaccustomed to getting along with people
symptoms: computer depression
causes: long-term computer operation forms an "either-or" thinking pattern, unaccustomed to reaching compromise and understanding with people, losing self-confidence, and being physically and mentally exhausted, which makes it difficult to start work.
mitigation methods
1. Do a good job of self-psychological adjustment and correct the way of thinking in time.
2. Actively handle interpersonal relationships, especially with colleagues.
count 8: emotional stress and irritability due to excessive dependence on computers
symptoms: computer mania
pathogenic cause: excessive dependence on computers.
