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.

Beware of computer dangers
In the office, computers are our most important office supplies. It's hard to imagine how we would work without it. But unfortunately, when we enjoy the convenience brought by computer, we have to accept its threat to our physical and mental health. Therefore, we urgently need to know about computer "diseases" and prevent them. 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.
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: They are rich in protein, lecithin, vitamins, calcium, phosphorus and iron, and 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.
Eye health killer
alcohol
Alcohol is the number one enemy of beautiful eyes. Excessive drinking will lead to dull eyes and bloodshot eyes; Long-term alcoholism can lead to rough skin and long spots in eyes.
The way to deal with this enemy is: try to stay away from alcohol; If you really can't avoid drinking, you must drink more water or eat some fruit to offset its adverse effects on the skin.
tobacco
Recent scientific research has 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 in the skin, which will lead to wrinkles around the eyes.
Even if you don't smoke, you shouldn't let your guard down. Secondhand smoke can also damage your body, mind and appearance. Are you really happy with friends who smoke? Does Alice really mind wrinkles climbing up the corner of her eyes? If you are not so worried, keep a certain distance from them.
Computer "disease" is often formed slowly, with weak explosive power and no obvious harm to the body. It's easy to be ignored. Although it will not cause life-threatening, it should not be underestimated. It will cause chain diseases in other aspects of the body, affect the quality of work and life, and have great potential harm to the human body. Therefore, for people who have to use computers for a long time, it is very important to do a good job of protection.
