Sitting in front of the computer for a long time will cause various problems, some may already know, some may not know Deep vein thrombosis High blood viscosity, slow blood flow and damage to the blood vessel wall are the three main causes of this disease, which occur mostly after various operations, long-term bed rest due to chronic diseases, and people with limited physical activity due to various reasons. It is easy to cause physical disability after illness, and severe cases can endanger the patient's life. And the love net people who don't like sports in front of the computer for a long time, still have more exercise! Influence visual system A man using a computer before going to bed can also have an adverse effect on the visual system. Since the eye belongs to the sensitive organ of the human body to electromagnetic radiation, excessive electromagnetic radiation pollution may also affect the visual system. Mainly manifested as decreased vision, causing cataracts and so on. Upper limb dysfunction Upper limb dysfunction caused by prolonged use of the computer includes neck paralysis, paralysis of the hands and feet, persistent pain, and the inability to lift heavy objects. It is recommended to play with walnuts when you are okay, practice brushwork, or play badminton, and exercise the whole body to activate the blood circulation of the upper limbs. waist pain Poor sitting posture often leads to back pain, and I believe that everyone has a deep understanding of this.

Radiation is easy to induce cancer Computer radiation pollution can affect the body's circulatory system, immune, reproductive and metabolic functions, and it can also induce cancer and accelerate the proliferation of cancer cells. Affect the reproductive system The main affecting people's reproductive system is the reduction of sperm quality in men, spontaneous abortion and fetal malformation in pregnant women. The sperm fertilization ability of men exposed to computer electromagnetic radiation in the long and medium term is normal, but the sperm fertilization function has been reduced compared with the use of computers less than 2 hours per week. Computer radiation can cause structural and functional damage to the testes, affecting reproductive hormone levels, and causing decreased sexual function and fertility. So, how can we prevent the various problems that arise from long-term work in front of the computer? Here are a few common ways to learn together. Use your eyes for 1 hour and rest for 10 minutes.

The shoulder blade rests on the back of the chair, the shoulders are lowered, the chin should not be close to the neck, and the distance between the eyes and the screen should be 40-50 cm. In addition, the height of the computer chair is very important, the seat is slightly hard, and the height can be bent 90 degrees naturally or slightly forward, and the foot should be placed on the ground.

It is best to take a break in 30 minutes. You can take a walk outside, or look up at the sky, or look into the distance, or practice stretching neck and chest for 10 to 20 times. Keep your skin clean There is a large amount of static electricity on the surface of the computer screen, and the accumulated dust can be transferred to the exposed parts of the face and hands. For a long time, it is prone to rash, pigmentation, and even skin lesions. In order to reduce radiation, the office should be kept ventilated and dry, so that harmful substances can be discharged as soon as possible. Putting a basin of water under the computer desk or putting a pot of flowers can also reduce radiation. Washing your face can also prevent radiation waves from irritating the skin. Of course, in addition to developing good habits, diet is also very important. Therefore, you should add more nutrients before you can do a computer. Let's take a look at what nutrients to add. Vitamin A It can form a photosensitive substance on the surface of the retina, and night blindness is caused by the lack of vitamin A. Zhao Qiang, head of the nutrition section of the Taipei District of Taiwan's Ma Rong Hospital, pointed out that staring at the computer screen for a long time would consume a lot of vitamin A. The most common foods rich in vitamin A are animal guts, but they contain high levels of cholesterol and are not suitable for large-scale consumption. It is recommended to eat foods containing more beta carotene, such as carrots, spinach and other green and yellow vegetables, yellow fruits, eggs, dairy products, etc., because the average beta carotene in the body will be converted into vitamin A. However, vitamin A and beta carotene are fat-soluble and eat better with fat, so it is best to eat or eat after meals. Beta carotenoid In addition to beta carotene, other members of the carotenoid family, such as lutein and zeaxanthin, can contribute to eye health. Sources of carotenoids include dark yellow, dark green and red fruits and vegetables such as pumpkin, green pepper, tomato, corn, papaya, cantaloupe, mango, watermelon, etc. Lutein and zeaxanthin can be found in dark green leafy vegetables such as spinach, kale, mustard, and celery.

Whole grains such as brown rice, germ rice, whole wheat bread, as well as liver, lean meat, yeast, milk, beans, green vegetables, etc., are rich in B vitamins. Vitamin C Zhao Qiang said that guava, kiwi, papaya, orange, orange, grapefruit, strawberry and so on contain more vitamin C. At the same time, the vitamin C of the seasonal fruits is higher. Some vegetables have both vitamin C and 夂懿匪兀缜 m贰 13. 胬 muscle (10) 蓟 蓟 2 2 2 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 10 Try to eat raw as much as possible to reduce nutrient loss. Vitamin E Vitamin E is also an antioxidant, vegetable oil (such as olive oil, soybean oil, peanut oil, sunflower oil, etc.), nuts (such as walnuts, almonds, cashews, peanuts, pine nuts, sunflower seeds, etc.), wheat germ, are vitamin E a good source. However, Zhao Qiang reminded that to control the intake of oil, take the porcelain spoon of the meal, up to two tablespoons a day. Nuts are not low in energy and can only eat up to two at a time. Nuts should be fried without salt and without sugar. anthocyanin The Mayo Medical Center of the United States pointed out that anthocyanins, an antioxidant, can enhance night vision and slow down the deterioration of the macula. Vegetables, fruits or berries of red, purple, purple, blue, etc., such as red beets, blueberries, cranberries, black cherries, purple grapes (skin), California Li, etc., all contain anthocyanins. Zinc The body needs to remove free radicals and needs minerals such as zinc to help. In addition, studies have found that the lack of zinc may lead to macular degeneration. Zinc is found in all seafood such as oysters, shellfish, and fish and shrimp. In addition, wheat and nuts also contain zinc. Conclusion: Before sitting on a computer, perhaps because of work needs, perhaps because of play, but inevitably, it has caused great harm to our body, so in order to prevent more possible harm in the future, we should Now it's a good habit to use a computer, and continue to do so, so that it can minimize the damage caused to us by long-term use of computers.
