Count one: electromagnetic radiation
Symptoms: insomnia, endocrine disorders.
Cause of disease: When the monitor is too hot, there will be a considerable amount of electromagnetic radiation when it is working, which will ionize the air, constantly produce positive charges (positive ions), and constantly neutralize them 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 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 side 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. 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 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 beans can clear away heat and detoxify, induce diuresis and reduce swelling, while Coix seed can strengthen the spleen and stop diarrhea, lighten the body and replenish qi. It 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 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 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 method
1. Don't put a mountain of papers and documents around the computer. You should put all the necessary documents into the cabinet in different categories, because the dust on papers and documents is usually not easy 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 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 screen flashes and emits heat, resulting in dry environment.
Symptoms: dry eye
Cause of disease: Although it can't be seen by naked eyes, in fact, the picture on the monitor is always 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, 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 method
1. It should be more than 70cm away from the display, and placed 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.
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. Because it is necessary to avoid the images of your face, lights and objects appearing on the screen (all light and shadow will double the fatigue of your eyes), it is necessary to 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 of the computer user. If you wear glasses, you should get yourself a pair of lenses with anti-reflective coating.
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, 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 them and grind them into powder. 500 grams of walnut kernel, stir-fry slightly to remove clothes, and mash it like mud after cooling. Take each 1 spoon of the above two kinds of food, pour it into boiled milk 1 cup, add honey 1 spoon, 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 the 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 then hand muscle atrophy. The problem is that typing on the keyboard or moving the mouse repeatedly every day leads to long-term, intensive, repeated and excessive activity of wrist joints, 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.
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 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 that of the elbow 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 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 your wrist.
4. Don't beat 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: Decreased brain function
Symptoms: memory is handsome.
Cause of disease: With the increasing popularity of personal computers, people are increasingly troubled by memory loss. The main reason is that they rely too much on computers, which weakens their brain functions.
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 shortage 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 20-30 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 you must use electronic files, you can try to use the handwriting board to input words.
5. Change the unhealthy diet and eat more brain-nourishing food.
Count 6: Sitting incorrectly for a long time.
Symptoms: pain in neck, shoulders and waist.
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 sore back, numb neck and shoulders and inflexible arms after working for an 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, so that the head can be supported, the shoulders droop naturally, the upper arm is close to the body, and the elbow is bent at 90 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 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 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 by the arm. 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 to 10 minutes every hour, do soft exercises or local massage, and at the same time develop regular exercise habits, and conduct lacing and muscle strength training for shoulders, necks 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 90 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. Soothing gymnastics
A: Basic posture: Before each training exercise, stand naturally, with eyes looking straight, feet slightly apart, shoulder width apart, and hands drooping naturally. Relax all over.
B: Leaning forward and leaning back: hands akimbo, head up and leaning back first, while inhaling, eyes looking up at the sky, 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 to 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 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 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 seven: thinking is stereotyped and I am not used to getting along with others.
Symptoms: computer depression
Cause of disease: Long-term computer operation forms an "either-or" mindset, and I am not used to reaching compromise and understanding with others, losing self-confidence and being physically and mentally exhausted, which makes it 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 handle interpersonal relationships, especially with colleagues.
Count 8: Emotional stress and irritability due to 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, agitated and uneasy, and even have a tendency to "use force" on the computer, such as punching the keyboard and mouse hard, swearing at the computer, smashing the computer, etc., and 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, and avoid sitting alone at the computer desk. You should 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 the computer has problems, 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 primary substance for strengthening the brain. It plays an important role in developing the complex and delicate functions of the brain.
Representative foods are nuts, sesame seeds, animals raised in nature, etc.
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 include lean meat, eggs and fish. Carbohydrate is the energy source of brain activity. After it is 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 include fresh fruits and yellow-green vegetables.
3. B vitamins: It is an assistant of intellectual activities. Including vitamin B 1, vitamin B2, folic acid, etc. When B vitamins are seriously insufficient, it will cause mental disorders, irritability, inattention and difficulty in maintaining mental stability. Representative foods include mushrooms and wild vegetables. Nuts contain a lot of protein, unsaturated fatty acids, lecithin, inorganic salts and vitamins, which are beneficial to improve brain nutrition supply if eaten regularly. Lentinus edodes has obvious curative effect on hypertension and arteriosclerosis, and has the effects of eliminating fatigue, refreshing, stabilizing spirit, preventing anemia and cancer.
4. Egg: It is rich in protein, lecithin, vitamins, calcium, phosphorus and iron, and is an indispensable substance for brain metabolism. In addition, eggs contain more acetylcholine, which is necessary for the brain to complete memory.
5. Fish: It can provide the brain with rich protein, unsaturated fatty acids, calcium, phosphorus, vitamin B 1, vitamin B2, etc. They are all important substances that constitute brain cells and improve their vitality.
6. Day lily: It is rich in protein, fat, calcium, iron, vitamin B 1, which are all needed by brain metabolism, so it is called "brain-nourishing dish".
7. Onion: It 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-strengthening effect.
8. Millet: It is rich in nutrients such as protein, fat, calcium, iron, vitamin B 1, and is known as the "brain-nourishing staple food". Millet also has the effect of preventing and treating nervous weakness.
9. Longan: It can nourish the heart and spleen, nourish the 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, which is a typical alkaline food and can eliminate the harm to the nervous system caused by long-term computer use. Eating regularly can make people energetic and have the effect of refreshing their minds and promoting memory. In addition, oranges and lemons have similar effects.
Eye protection element
1. Vitamin C: It's also very 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. Therefore, we should 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 care product.
3. Tomato: It is 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: Because the computer operator's eyes stare at the computer screen for too long, the photosensitive substance rhodopsin on the retina can be consumed too much. If the synthetic substance vitamin A and related nutrients are not replenished in time, it will lead to decreased vision, eye pain, fear of light, and reduced dark adaptability. Therefore, computer operators need more vitamin A than ordinary people, so they should eat more foods rich in vitamin A.
5. Lycium barbarum L.: It is rich in beta carotene, vitamin B 1, vitamin C, calcium and iron, and has the functions of nourishing the liver, tonifying the kidney and improving eyesight, because it is sweet in itself. Whether it is to make tea or eat it as a snack like raisins, it will be of great help to the problems of computer families such as sour 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 it with honey and chrysanthemum tea, which is also very effective for relieving eye fatigue.
Eye health killer
alcohol
Alcohol is the number one enemy of beautiful eyes. Excessive drinking can lead to dull eyes and bloodshot eyes; Long-term alcoholism will lead to rough skin and spots on the eyes.
The way to deal with this enemy is: hide away from alcohol as far as possible; If you really can't avoid drinking alcohol, you must drink more water or eat some fruit to offset its adverse effects on the skin.
tobacco
Recent scientific research has more clearly pointed out that once tobacco is burned, it is definitely an enemy that cannot be ignored. Not only does it do great harm to the respiratory system, but long-term smoking will also accelerate skin aging. The smoke produced by tobacco burning will take away a lot of water from the skin, which can lead to wrinkles around the eyes.
Even if you don't smoke, you shouldn't let your guard down. Secondhand smoke will also destroy your body, mind and appearance. Are you really happy when you get together with your friends who smoke? Is it true that silk doesn't mind wrinkles climbing up the corner of her eyes? If you are not so relieved, just keep a certain distance from them.
Computer "disease" is often formed slowly, and its explosiveness is not strong, and its harm to the body is not very obvious. It is easy to be ignored. Although it will not cause life danger, it should not be underestimated. It will cause chain diseases in other aspects of the body, affect the quality of work and life, and it has great potential harm to the human body. Therefore, it is very important for people who have to use computers for a long time to do a good job of protection.
