The Internet age makes people fully realize the magic brought by digital technology, but it also brings some health concerns. At present, the impact of computers and networks on health has aroused great concern.

The keyboard is a "garbage dump"

In the course of daily work, many people may not realize that frequently used keyboards may cause diseases.

First of all, the keyboard is a "garbage dump" with dust, hair, hair, eyelashes and so on. According to statistics, this kind of dirt accumulates at an average rate of 2 grams per month. In addition, the keyboard surface is covered with a large number of bacteria, such as Streptococcus, Staphylococcus aureus, Aspergillus fumigatus and so on.

The harm of computer radiation to the body can not be ignored.

A British study confirmed that low-frequency radiation and magnetic fields emitted by computer screens can cause 7- 19 diseases, including itchy eyes, neck and back pain, transient memory loss, irritability and depression. Computer radiation is also easy to cause abnormal reproductive function and embryonic development in women. According to the investigation of more than 200 computer operators in Wuhan banking system, more than 35% of women have symptoms such as dysmenorrhea and prolonged menstrual period, and a few women have premature delivery or abortion. According to the research of the World Health Organization, if pregnant women use computers for more than 20 hours a week, the incidence of abortion will increase by more than 80%, which may also lead to fetal malformation.

Among them, when the eyes are itchy, dry and sour, the eyes are only in the stage of functional injury. However, if we don't pay attention to protect our eyes at this time and make them dry for a long time, it will lead to corneal epithelial cells falling off, causing organic damage, further aggravating symptoms and seriously affecting our vision.

Cervical dorsal syndrome caused by long-term tension or injury of neck muscle and soft tissue will develop into cervical spondylosis if it is not treated in time.

Women who have been engaged in computer-related work for a long time have a higher risk of breast cancer than non-computer workers. This is a survey in Taiwan Province Province. At present, there are more than 3 million computers in Taiwan Province Province, and most of them are women. If you work in front of the computer for a long time, it will increase the risk of breast cancer; Premenopausal women are more likely to develop breast cancer than postmenopausal women. After the reproductive health of professional women is damaged, the main manifestations are menstrual disorder, pregnancy-induced hypertension syndrome, early menopause, decreased fertility, spontaneous abortion, low birth weight, congenital malformation and even fetal death.

The most radiant part of the computer

The radiation on the back of the computer is the strongest, followed by the left and right sides, and the radiation on the front of the screen is the weakest. So try not to let the back of the screen face someone, and the distance should be at least 50 cm to 75 cm, which can reduce the harm of electromagnetic radiation.

How to minimize the harm of computer radiation to human body

Pay attention to the details of life and maintain health bit by bit.

1. Avoid operating the computer continuously for a long time and pay attention to rest. To maintain a most suitable posture, the distance between the eyes and the screen should be 40~50 cm, so that the eyes can look down or slightly down at the screen.

2. Maintain a good indoor working environment, such as comfortable temperature, clean air, proper negative ion concentration and ozone concentration.

3. The light in the computer room should be suitable, neither too bright nor too dark, so as to avoid the interference of light caused by direct irradiation on the fluorescent screen. The studio should be kept ventilated and dry.

4. Color filters should be used on the computer screen to reduce visual fatigue. It is best to use glass or high-quality plastic filters.

5. Install protective devices to reduce the intensity of electromagnetic radiation.

6. Pay attention to keep your skin clean. There is a lot of static electricity on the surface of computer screen, and the accumulated dust can be transferred to the exposed parts of face and hand skin for a long time, which is prone to macula and pigmentation, and even cause skin lesions in severe cases.

7. Pay attention to supplementary nutrition. Computer operators working in front of the screen for too long will consume rhodopsin on the retina, which is mainly synthesized by vitamin A. Therefore, computer operators should eat more foods such as carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal livers and lean meat to supplement vitamin A and protein in the human body. Drink more tea, tea polyphenols and other active substances in tea can help absorb and resist radioactive substances.

Six points for attention in health care of "computer family"

At present, people pay more and more attention to the negative effects of computers on human physiology and psychology. Therefore, we should use computers scientifically to reduce the harm of computers and networks.

First, enhance self-care awareness and pay attention to proper rest during work. Generally speaking, computer operators should rest for about 1 0 minutes after continuous work. And it is best to move your hands, feet and torso outside the operating room. At ordinary times, we should strengthen physical exercise, enhance physical fitness, and conduct regular physical examination and self-psychological measurement.

Second, pay attention to the working environment. The light in the computer room should be suitable, neither too bright nor too dark, so as to avoid interference caused by direct light irradiation on the fluorescent screen. The studio should be ventilated and dry, so that those harmful gases can be discharged as soon as possible, and try to reduce noise with a non-impact printer.

Third, pay attention to the correct operating posture. The center of the computer screen should be installed at the same height as the operator's chest, and it is best to use a chair with adjustable height. When sitting, you should have enough space to stretch your feet and don't cross your legs, so as not to affect blood circulation.

Fourth, pay attention to protect your eyesight, avoid operating the computer continuously for a long time, and pay attention to rest in the middle. To maintain a most suitable posture, the distance between the eyes and the screen should be 40-50 cm, so that the eyes can look down at the screen horizontally or slightly, which can relax the neck muscles and minimize the exposed area of the eyeball. If you have dry eyes, redness, burning or foreign body sensation, heavy eyelids, blurred vision, or even eye pain or headache, you need to go to the hospital to see an ophthalmologist.

Five, pay attention to the computer operators who work too long in front of the screen, rhodopsin on the retina will be consumed, and rhodopsin is mainly synthesized by vitamin A. Therefore, computer operators should eat more carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal liver, lean meat and other foods to supplement vitamin A and protein in the human body. Drink more tea, tea polyphenols and other active substances in tea can help absorb and resist radioactive substances.

Sixth, pay attention to keep your skin clean. There is a lot of static electricity on the surface of computer screen, and the accumulated dust can be transferred to the exposed skin of face and hands. After a long time, it is easy to cause macula and pigmentation, and even cause skin lesions in severe cases.

Health care of computer families

Computer people can drink more green tea and chrysanthemum tea.

In addition to being exposed to electromagnetic radiation, the flicker of computer screen also has a strong stimulating effect on eyes.

People who use computers for a long time are prone to eye diseases. Experts believe that drinking more green tea at ordinary times can play a certain anti-radiation role. In addition, chrysanthemum also has a good effect on treating eye fatigue and blurred vision. For computer families who often feel dry eyes, drinking chrysanthemum tea is beneficial and harmless.

Many people know that long-term use of computers will affect health.

Computer families are prone to varicose veins of lower limbs, cervical spondylosis, lumbar disc herniation and eye diseases.

Eyes are in a state of tension

Because the computer patriarch sits in front of the computer for a long time and sees things closer, it forces the ciliary muscles of the eyes to be in a state of contraction and tension, thus making the lens bulge to adapt to nearby objects. Long-term eye tension without rest can lead to myopia. Excessive visual fatigue can also lead to the obstruction of aqueous humor operation, which is more likely to lead to glaucoma. At the same time, dry eye, cataract, corneal ulcer and retinal detachment are also common eye diseases for long-term computer users.

In addition to being exposed to electromagnetic radiation, the flicker of computer screen also has a strong stimulating effect on eyes, causing people to cry, vision loss, dizziness and other symptoms.

Anti-radiation effect of green tea

Experts believe that drinking more green tea at ordinary times can play a certain anti-radiation role. Shennong Materia Medica lists tea as one of 365 kinds of medicines, and says: "Drinking tea tastes bitter, which makes people think better, lie down less, make them healthy and improve their eyesight."

Experts believe that vitamin C and vitamin E contained in green tea, especially tea polyphenols, have strong antioxidant activity and can remove oxygen free radicals in the human body, thus playing a role in anti-radiation and enhancing the body's immunity.

In addition, tea contains carotene, which can be converted into vitamin A under the action of intestinal wall and liver. Vitamin A can nourish eyes, relieve eye fatigue and prevent night blindness.

Make the brain more agile

Not long ago, British scientists found that drinking tea can prevent the synthesis of an enzyme in the human body, which will destroy acetylcholine, the medium that transmits information between brain cells. Therefore, drinking tea has another advantage for office workers who often use computers, which is to make their brains more agile.

Previous medical reports show that there are more than 700 known compounds isolated and identified in tea, including protein, fat, sugar, polyphenols, saponins, alkaloids, theanine, pigments and aromatic substances.

Chrysanthemum tea protects eyes.

In addition, computer families can also use chrysanthemum tea to "care" their eyes. People in China have known since ancient times that chrysanthemum has the function of protecting eyes. Chrysanthemum has a good effect on treating eye fatigue and blurred vision.

Lycium barbarum chrysanthemum tea

"Compendium of Materia Medica" records that chrysanthemum is "sweet in nature, cold in taste, and has the effects of dispelling wind and clearing heat, calming the liver and improving eyesight". Modern pharmacology shows that chrysanthemum is rich in vitamin A, which is an important substance to maintain eye health. Chrysanthemum tea can make people clear-headed and bright eyes, especially for dry eyes caused by excessive liver fire. For computer families who often feel dry eyes, drinking chrysanthemum tea is beneficial and harmless.

The drinking method of chrysanthemum tea is very simple, as long as the dried chrysanthemums sold in the market are soaked in water or boiled. Usually, you can soak one or two cups of chrysanthemum tea regularly, which can achieve the effect of eye care. If you drink three or four cups of chrysanthemum tea every day, it will also help your eyesight.

Some people also like to add Lycium barbarum to chrysanthemum tea. The brewed tea is the famous "Chrysanthemum Lycium Tea", which has a higher eye protection effect, because chrysanthemum and Lycium barbarum are both Chinese medicines for eye protection.

It is worth noting that people who are cold in chrysanthemum, cold in constitution, afraid of cold at ordinary times and prone to cold hands and feet should not drink it often, but should drink it in moderation.
