Item 1: Electromagnetic radiation

Symptoms: insomnia, endocrine disorders.

Cause of disease: the monitor is too hot, and there will be a considerable amount of electromagnetic radiation when working, which will ionize the air, constantly produce positive charges (positive ions), and constantly neutralize the negative ions in the air, resulting in almost zero negative ion content. The more beneficial negative ions, the more harmful positive ions. Being in an environment with too many positive ions for a long time, it enters the lungs through breathing, and then it is transported to various tissues of the human body with blood circulation, which makes people's blood and body fluids acidic, delays the normal metabolic function of the body and accumulates toxins in the body. Causes insomnia, decreased immunity, and female endocrine disorders.

Mitigation method

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. So, don't point the back of the monitor at the back of your colleague's head or the side of your body.

4. Drink green tea often. 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 renal cortex secrete hormones against stress, greatly improving the mood. But it is best to drink it during the day, so as not to affect sleep.

5. Mung beans can clear away heat and detoxify, induce diuresis and reduce swelling, and coix seed can strengthen the spleen and stop diarrhea, and lighten the body and replenish qi. Often need to work late or when fidgety, dry mouth, constipation, it is very helpful to eliminate fidgety.

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.

Item 2: Dust field

Symptoms: skin allergy

Cause: An electrostatic field will be formed around the turned-on monitor, 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 skin rash. Sitting in front of the computer, your surroundings are full of air containing a lot of dust particles, so the user's skin is very prone to allergic phenomena such as rash.

Mitigation method

1. Don't put mountains of papers and documents around the computer, but put all the necessary documents in the cupboard in different categories, because the dust on papers and documents is usually not easy to clean up.

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 the towel with chamomile extract (a simpler method is to use a wet chamomile tea bag) and apply it directly to your forehead and cheeks.

5. Put a cactus on the computer desk, because the acupuncture of cactus can absorb dust.

6. Clean the keyboard frequently. Wash your hands when and after using the keyboard and before eating. Cover the keyboard with a cloth when not in use. Because the keyboard is uneven, it is very easy to accumulate dust, which will become a hiding place for skin diseases and cold germs.

Count three: the screen flashes and heats up, causing the environment to be dry.

Symptoms: dry eye

Cause of disease: Although it is invisible to the naked eye, the picture on the monitor has been flashing. 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, swollen and painful. Almost everyone's eyes will feel sore and trachoma after working in front of the computer for 4 hours without interruption. The working environment of computer workers is closed, the humidity in the environment is low, and the computer keeps heating up. In a dry environment, the tear layer will evaporate in a few seconds, which has become an important cause of dry eye.

Mitigation method

1. It should be more than 70cm away from the monitor and placed slightly below 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 won't make your eyes tired.

When working in front of the computer, the room should not be too dark or too bright. The ideal office environment is that the brightness of the room is the same as that of the screen.

4. Because you want to avoid the images of your face, lights and objects on the screen (all light and shadow will double the fatigue of your eyes), you should avoid the direct illumination of indoor light on the screen to produce interference light. The light source should preferably come from the left or right side of the computer user. If you wear glasses, you should buy yourself a pair of lenses with anti-reflective coating.

In order to prevent conjunctival dryness, we should drop some eye drops with the same composition as our tears when using the computer.

6. When eyes are tired, apply a wet towel boiled with light black tea for a few minutes, which will quickly eliminate congestion and fatigue.

7. Stir-fry 500 grams of black beans, cool and grind into powder. 500 grams of walnut kernel, slightly fried, stripped, cooled and mashed into mud. Take the above two foods 1 spoon, pour them into 1 cup of boiled milk, add 1 spoon of honey, and take them in the morning or after breakfast. It can strengthen the muscle strength in the eye, strengthen the regulation function and improve the symptoms of eye fatigue.

Point 4: Use the mouse for a long time.

Symptoms: mouse hand (wrist joint syndrome)

Cause of disease: Long-term use of computer keyboard and mouse may be associated with a disease called wrist joint syndrome, which leads to pain and numbness of index finger or middle finger, muscle weakness of thumb, which may lead to nerve damage, and then lead to muscle atrophy of hand. The problem is that knocking on the keyboard or moving the mouse repeatedly every day leads to long-term, intensive, repetitive and excessive activity of the wrist joint, which leads to injury or oppression of peripheral nerves and blocks nerve conduction, thus causing sensory and motor disorders of the palm. In addition, the elbow is often lower than the wrist, the hand is held high, the nerve and tendon are often compressed, the hand will start to numb, the fingers will lose flexibility, and joint pain often occurs. 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, hypoxia and numbness. The survey shows that 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.

Mitigation method

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 actions 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 height of the elbow when sitting, which is beneficial to reducing the damage to the tendon sheath of the wrist when operating the computer.

3. When using the mouse, don't suspend your arm to reduce the pressure on your wrist. When moving the mouse, don't use wrist force but try to rely on arm force to reduce the stress on the wrist.

4. Don't push the buttons of the keyboard and mouse too hard, and it is better to be relaxed and moderate.

5. It is best to choose a mouse with large radian and wide contact surface, which is helpful for dispersion.

6. When using the mouse, use the "mouse wrist pad" to pad your wrist.

Item 5: Decline of brain function

Symptoms: Good memory.

Etiology: With the increasing popularity of personal computers, people are increasingly troubled by memory decline. The main reason is that they rely too much on computers and weaken their brain function.

Mitigation method

1. Lie flat on the bed before going to bed, relax all over, 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, it is essential to sleep for 8 hours every day. We should try our best to ensure the quality of sleep and adjust the blood circulation in the cerebral cortex in time.

3. Practice meditation. It is best to have 20-30 minutes every day to meditate on the relaxing and beautiful things in life, 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, the comfort shall prevail.

4. Learn to use the five-stroke input method instead of the associative input method of intelligent pinyin all the time. Try not to use the computer to input handwritten words. Even if you must use electronic documents, you can try to input words with the handwriting board.

5. Change unhealthy diet and eat more brain-nourishing food.

The sixth measure: sitting incorrectly for a long time.

Symptoms: Neck, shoulder and waist pain.

Cause of disease: If you hold your arms high, head down and cross your legs under the table when using the computer, you will feel backache, 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.

Mitigation method

1. The upper body should keep the neck upright, which can support the head, the shoulders naturally droop, the upper arm is close to the body, and the elbow is bent 90 degrees. Operate the keyboard or mouse to keep the wrist as horizontal as possible. The center line of the palm and the center line of the forearm should be kept in a straight line. The waist of the lower body is straight, the knees naturally bend 90 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 to follow the "three right angles": the knee under the computer desk forms the first right angle, the thigh and back form the second right angle, and the arm forms the third right angle near 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. Look straight at the center of the computer screen, preferably with a supported chair back and armrest, and the height can be adjusted.

3. Flying a kite: When flying a kite, you can hold your chest out and look around, which can maintain the muscle tension of cervical vertebrae and spine, keep the elasticity of ligaments and the flexibility of spine joints, help to enhance bone metabolism and enhance the compensatory function of cervical vertebrae and spine, and prevent the degeneration of vertebrae and ligaments. It is indeed a good way to prevent and treat cervical spondylosis left by our ancestors.

4. Swimming: Because the head is always raised 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 of cervical spine exercise.

5. When using the computer, you should rest for 5 ~ 10 minutes every hour, do soft exercise or local massage, and at the same time develop regular exercise habits, and do stretching and muscle strength training for shoulders, 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 height 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, bend your knees 90 degrees naturally 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 computer monitor form a slightly downward gaze angle on the screen, which can relax the neck muscles.

8. Soothing gymnastics

A: Basic posture: Before each training exercise, stand naturally, look straight at your eyes, separate your feet slightly, shoulder width apart, and hang your hands naturally. Relax all over.

B: lean forward and lean back: put your hands on your hips, head up and then back, inhale at the same time, look up at the sky, and pause for a minute; Then slowly lower your head to the chest position, exhale at the same time, and look at the ground. When doing this, keep your mouth closed and keep your chin as close to your chest as possible. After stopping for one minute, do it up and down four times. The essence of 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, inhale into your chest and straighten your right neck, then stop for one minute, then slowly turn to the right, exhale and straighten your left neck, and then stop for another 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, lift your shoulders slowly and shrink your neck as much as possible. After stopping for one minute, the shoulders slowly relax, the head and neck naturally stretch and return to nature. Then, the shoulders sink hard and the head and neck are pulled up. After stopping for one minute, relax your shoulders and exhale naturally. Pay attention to inhale slowly when stretching your neck, hold your breath when staying, and relax your shoulders and neck as much as possible when relaxing your shoulders. After returning to the natural style, do it again four times.

E: Swing from side to side: Before doing exercises, stand naturally, with eyes straight up, 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 stopping for one 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 stopping for a minute, return to the middle position. This swing from side to side is repeated four times. Inhale when your head swings, exhale slowly when you return to the middle position, and try to relax your shoulders and neck when doing exercises. It is best to move slowly and steadily.

Count seven: rigid thinking and unaccustomed to getting along with others.

Symptoms: computer depression

Causes: Long-term computer operation has formed an "either-or" mindset, and I am not used to reaching compromise and understanding with others, losing self-confidence, being physically and mentally exhausted, and it is difficult to start my work.

Mitigation method

1. Do a good job of self-psychological adjustment and correct the way of thinking in time.

2. Actively deal with interpersonal relationships, especially with colleagues.

Eighth measure: emotional tension and irritability caused by excessive dependence on computers.

Symptoms: computer mania

Cause of disease: due to excessive dependence on the computer, when the computer fails, it will be nervous, irritable and uneasy, and even have a tendency to "use force" on the computer, such as banging the keyboard and mouse hard, swearing at the computer, smashing the computer, etc. Some will vent their dissatisfaction on family members or colleagues.

Mitigation method

1. Once the computer breaks down, find a professional to repair it immediately, avoid sitting alone at the computer desk, divert your attention and relax as soon as possible.

2. Save the working documents at any time and back up the data with the mobile hard disk, so that once there is a problem with the computer, it will not suffer too much loss and the mood will not suddenly get out of control.

Don't sit in front of the computer for a long time. Go away for a cup of tea, coffee or exercise your limbs every once in a while.

Healthy food for computer families

Brain-strengthening element

1. fat: it is the main substance to strengthen the brain. It plays an important role in developing the complex and delicate functions of the brain.

Representative foods are nuts, sesame seeds and animals raised in nature.

2. protein: It is the material basis of intellectual activities and the main substance to control the process of brain cell excitation and inhibition. Representative foods are lean meat, eggs, fish and so on. Carbohydrate is the energy source of brain activity. After being decomposed into glucose in the body, it becomes an important energy source for the brain. Representative foods include miscellaneous grains, brown rice, brown sugar, cakes and so on. Adequate vitamin C can make the brain function flexible and sharp, and improve IQ. Representative foods are fresh fruits, yellow-green vegetables and so on.

3.b vitamins: an assistant to intellectual activities. Include vitamin B 1, vitamin B2, folic acid, etc. When B vitamins are seriously deficient, it will cause mental disorders, irritability, inattention and difficulty in maintaining mental stability. Representative foods are mushrooms and wild vegetables. Nuts contain a lot of protein, unsaturated fatty acids, lecithin, inorganic salts and vitamins. Regular consumption is conducive to improving the nutritional supply of the brain. Lentinus edodes has obvious curative effect on hypertension and arteriosclerosis, and has the functions of eliminating fatigue, refreshing mind, stabilizing spirit and preventing anemia and cancer.

4. Eggs: rich in protein, lecithin, vitamins, calcium, phosphorus and iron, are indispensable substances for brain metabolism. In addition, eggs contain more acetylcholine, which is necessary for the brain to complete memory.

5. Fish: It can provide rich protein, unsaturated fatty acids, calcium, phosphorus, vitamin B 1, vitamin B2 and so on for the brain. Are important substances that constitute brain cells and improve the vitality of brain cells.

6. Daylily: It is rich in protein, fat, calcium, iron and vitamin B 1, which are all needed by brain metabolism, so it is called "brain-nourishing dish".

7. Onion: contains anti-platelet aggregation substances, which can dilute blood and improve blood supply to the brain. It is of great benefit to eliminate mental fatigue and excessive tension. Eating half an onion every day can get a good brain-nourishing effect.

8. Millet: It is rich in nutrients such as protein, fat, calcium, iron and vitamin B 1, and is known as the "brain-nourishing staple food". Xiaomi also has the effect of preventing and treating neurasthenia.

9. Longan: It can nourish the heart and spleen, nourish blood and soothe the nerves. All forgetfulness, insomnia, palpitation and mental decline caused by deficiency of both heart and spleen can be adjusted by taking longan.

10. Grapefruit: It contains a lot of vitamin A, vitamin B 1 and vitamin C. It is a typical alkaline food and can eliminate the damage to the nervous system caused by long-term computer use. Eating regularly can make people energetic, refresh their minds and promote memory. In addition, oranges and lemons have similar effects.

Eye protection element

1. Vitamin C: It's also good for the eyes. The content of vitamin C in human eyes is several times higher than that in blood. With the increase of age, the content of vitamin C decreases obviously, and the lens is malnourished, which will cause lens degeneration over time. So eat more vegetables and fruits rich in vitamin C.

2. Spinach: It contains protein, fat, carbohydrate, crude fiber, calcium, phosphorus, iron, carotene, riboflavin, etc. It is not only a vegetable with high nutritional value, but also a good eye protection product.

3. Tomato: rich in vitamins, minerals, carbohydrates, organic acids and a small amount of protein. Because of its acidity, it has the function of protecting vitamin C and is not easy to be destroyed during cooking.

4. Vitamin A: Due to the computer operator's eyes staring at the computer screen for too long, rhodopsin, a photosensitive substance on the retina, will be consumed too much. If the synthetic substance vitamin A and related nutrients are not supplemented in time, it will lead to decreased vision, eye pain, photophobia and reduced adaptability to darkness. Therefore, computer operators need more vitamin A than ordinary people and eat more foods rich in vitamin A.

5. Lycium barbarum: It is rich in beta carotene, vitamin B 1, vitamin C, calcium and iron. It has the function of nourishing liver and kidney and improving eyesight, because it is sweet in itself. Whether you make tea or eat it as a snack like raisins, it will be of great help to the computer family's problems such as sore eyes, fatigue and decreased vision.

6. Chrysanthemum tea: It has the effect of improving eyesight and clearing liver. Some people simply make tea with chrysanthemum and medlar, or brew with honey and chrysanthemum tea, which is also very effective for relieving eye fatigue.
