The following is a brief description of both:
First of all, sunshine
Modern scientific research shows that there are mainly ultraviolet rays, infrared rays and visible light in sunlight. Among them, ultraviolet rays have the greatest influence on human body. Although this kind of light can't be seen by naked eyes, it can make the skin healthy, stimulate the body's hematopoietic skills, improve the body's immune ability, improve the body's glucose metabolism, promote the body's calcium and phosphorus metabolism and vitamin D synthesis, effectively prevent rickets or rickets, and also promote blood circulation, stimulate appetite and enhance physical fitness.
Infrared is also a kind of invisible light, accounting for 60%~70% of sunlight. It can penetrate into subcutaneous tissue through skin, stimulate human body, thereby dilating blood vessels, accelerating blood circulation, promoting metabolism in the body, and playing the role of diminishing inflammation and relieving pain.
Visible light is sunlight that the eyes can see. It consists of seven colors: red, orange, yellow, green, cyan, blue and purple. It can adjust people's mood, cheer up their spirits, improve people's life fun and work efficiency, and improve various physiological functions of the human body.
Chinese traditional medical theory attaches great importance to the effect of sunlight on human health, and holds that regular exposure to the sun is helpful to promote human yang, and can achieve the functions of strengthening yang, warming meridians and dredging collaterals.
Regular sun exposure is good for health. Regardless of spring, summer, autumn and winter, I suggest you go out and get in touch with the sun, as long as you avoid the scorching sun at noon and summer. Ultraviolet rays in the sun can kill bacteria in the air, and many molds can't survive in the sun; Ultraviolet rays can also kill bacteria on the skin, increase the elasticity and softness of the skin, and resist foreign bacteria. More sun exposure will make your skin dark and red, healthier and less prone to sores, acne and skin diseases. Sunlight on the skin can stimulate the hematopoietic function of the body, promote the metabolism of calcium and phosphorus in the body and the synthesis of vitamin D, and make your bones and body stronger; The infrared rays in sunlight can penetrate the skin and reach the subcutaneous tissue, which can stimulate the human body, speed up blood circulation, promote metabolism in the body, and have anti-inflammatory and analgesic effects. When there is a lack of sunshine, the brain will produce a kind of worry hormone, which makes people feel sleepy and depressed. Sunlight is the best stimulant, which can adjust people's mood, cheer up their spirits, relieve melancholy symptoms, improve life interest and work efficiency, and improve various physiological functions of the human body.
In short, sunshine has many benefits to human body, but choose sunny weather and be careful not to overexpose to avoid damaging skin and eyes; It is also not advisable to sunbathe on an empty stomach, full stomach and fatigue to avoid dizziness; Patients with severe heart disease, hypertension and nervousness, people who are allergic to sunlight, and women during menstruation and one month after delivery should be careful not to be overexposed to avoid accidents.
Benefits of sunbathing:
1, sunshine helps you supplement vitamin D.
Most of the health benefits of sunlight are related to its ability to increase the content of vitamin D in the body. Vitamin D controls the regeneration of human cells and helps the human body absorb nutrients beneficial to bones and teeth. As long as you get enough sunlight every day, you can meet 90% of your vitamin D needs, and the rest 10% needs to be obtained from your daily diet. Foods rich in vitamin D include fish, fish eggs, liver, egg yolk, cream, butter, cheese, meat, milk, fruits, nuts, vegetables and grains. However, it should be noted that if you don't accept the sun, you can't guarantee the demand for vitamin D simply by food.
2. Six Healthy Points
① Promote the health of bones and teeth.
Long-term avoidance of sunlight can easily lead to calcium deficiency. Ultraviolet rays in the sun can increase vitamin D in our body, which is very important for the health of bones. Vitamin d can improve the absorption of calcium and phosphorus in human body, and make the plasma calcium and phosphorus levels reach saturation level; It promotes bone growth and calcification and helps to keep teeth healthy.
If you receive too little sunlight, your body will lack vitamin D, so rickets, hand and foot convulsions, rickets and osteoporosis may all get you into trouble.
② Make the skin healthier.
If you love beauty, you are always afraid of being tanned or even sunburned, so you avoid the sun. In fact, sunshine is of great benefit to the health of the skin! It can enhance skin resistance, kill bacteria on skin, enhance skin elasticity, luster and softness, and make skin more perfect. The latest scientific research shows that sunlight can also prevent several kinds of skin cancers.
③ Improve immunity.
Ultraviolet rays in sunlight can stimulate cholesterol in human skin to be converted into vitamin D. Don't underestimate this very common vitamin. As long as 0.009 mg per day can improve your immunity 1 times.
Not only that, sunlight can also increase oxygen and white blood cells in the blood, so experts believe that sunbathing can improve people's immunity. Studies have shown that regular sunbathing can prevent colds and many infectious diseases.
④ Prevention of cancer
The latest medical research shows that sunlight can prevent the growth of some cancer cells, including several kinds of skin cancer, lymphatic adenocarcinoma and breast cancer. Fully accepting sunlight can increase vitamin D in your body, which scientists believe is the reason for the decrease of cancer incidence.
Scientists in Sweden and Denmark have found that ultraviolet rays in sunlight can reduce the risk of lymphoma by 30%~40%. A study by the University of New Mexico found that exposure to sunlight reduced the mortality rate of patients with malignant melanoma.
In addition, people who live in sunny environment will have a much lower risk of breast cancer. Some surveys show that people who live in sunny environment.
Give you a good mood.
You must feel that on a sunny day, your mood has become cheerful and your work efficiency seems to have improved. This is because sunlight can stimulate the brain to release a large number of chemicals that can produce pleasure, regulate emotions, make people refreshed, feel comfortable, and become positive and energetic.
⑥ Improve sexual interest.
Sunlight can also raise the level of sex hormones and make your sex life more like a duck to water. In fact, the influence of Yangguan on hormone level is remarkable, and it is even used to treat menopausal syndrome.
In addition, sunlight can prevent multiple sclerosis and rheumatoid arthritis.
(1) sunbathing, sunbathing.
Although sunbathing is of great benefit to health, exposure to the sun without protection, regardless of time and intensity, may harm the skin and even cause physical discomfort or skin cancer. Therefore, there must be surgery in the sun!
(2) Drying time
Compared with summer, autumn, winter and spring are mild sunshine seasons. Depending on the intensity of light, you can sunbathe for 5 to 30 minutes. It should be noted that the sun's ultraviolet rays are strongest between 1 1 and 3 pm every morning. It is best to avoid this time when sunbathing to avoid sunburn.
③ sunbathing posture
Expose your skin as much as possible and receive sunlight. You can choose the riverside, lakeside or beach bath in the suburbs, or lie or sit, or do it during activities. Pay attention to changing the position at any time to avoid uneven illumination.
④ Sun protection
When sunbathing, you should pay special attention not to overexpose, so as to avoid skin aging and even skin cancer caused by excessive ultraviolet radiation. When sunbathing, you should also pay attention to protecting your head and eyes to avoid dizziness and fatigue caused by excessive exposure.
Sunscreen is also essential when sunbathing. UVA (98.9% of ultraviolet rays) will tan your skin, and UVB (only 1. 1% of the total) will make your skin sunburned and red. Sunscreen can help you block most UVA and UVB and protect your skin. But don't think that wearing sunscreen is absolutely safe. Overexposure can still hurt the skin.
(5) sunbathing is not suitable for five situations:
People suffering from severe heart disease, hypertension, infiltrative tuberculosis and nervousness;
Those with bleeding tendency;
Women during menstruation and within one month after delivery;
When you are hungry, holding your stomach and tired;
People who are allergic to sunlight.
Second, computer radiation.
1, correlation principle
Experts have found that all household appliances that use electricity every day will produce electromagnetic radiation, which is harmful to human body. The most important thing is to look at the amount of radiant energy. According to the regulations of the International Radiation Protection Association and the International Labor Organization, the safe intensity of electromagnetic field is 0. 1 1-0.3 microtesla (this is the safe limit of electromagnetic field when computer is contacted for 24 hours), and there is no danger to human body below this intensity. A special research institution has tested the electromagnetic field intensity of the computer, and the results show that the electromagnetic field intensity near the screen is 0. 9, but it is less than 0. 1 at about 5 cm from the screen, and it is almost impossible to measure at 30 cm (this is the customary distance between the computer operator's body and the screen). In addition, electromagnetic waves in space are indeed everywhere, but generally speaking, the intensity of this electromagnetic radiation is very small and will not cause harm to human health. The Regulations on the Protection of Electromagnetic Radiation promulgated by China stipulates the standard limits of electromagnetic radiation pollution equipment and its impact on personnel. Only when the electromagnetic wave reaches a certain intensity, it needs special protection.
2. The harm of computer radiation to human body
① computer radiation leads to hair loss.
Radiation is the number one factor leading to hair loss; Too long computer use is also the key to hair loss; When the brain is highly concentrated on using the computer, the excitement of the brain will increase for a long time, and endocrine will be disordered. Sebaceous glands connected with hair follicles will secrete too much, leading to hair follicle embolism, blocked hair nutrition supply, brittle hair and hair loss. For slight hair loss, it can be alleviated by reducing computer use time and adjusting lifestyle.
② Damage to eyes
Blue radiation
With the traditional C RT display replaced by more and more LCD flat panel displays, LCD displays have obvious advantages over traditional CRT displays in solving screen flicker and luminous quality, but with the increasing popularity of LED lamps and flat panel displays, more and more opposition voices begin to appear.
According to the survey of the German authoritative computer magazine Macwelt, although the radiation of LCD screen is much smaller than that of ordinary display screen, it is easier to make our eyes tired and may even lead to symptoms such as headache because of its high brightness. This problem exists not only in LCD computers, but also in LCD TVs. In order to improve the definition, these LCD screens not only rely on the lamp behind the screen to improve the brightness, but also generally use special "polishing technology" to make the display surface look like a piece of glass, which is very textured, and also improve the color contrast and saturation of the screen. Consumers who use this kind of display screen for a long time are likely to be "stabbed" by light, and there will be symptoms of eye fatigue, which will gradually lead to health problems such as decreased vision and headache.
These "inappropriate lights" continue to irradiate our eyes, which will cause dysfunction, especially the light emitted by LED lamps and computer screens, which contains a lot of high-energy short-wave blue light with irregular frequency. These short-wave blue lights are extremely energetic and can penetrate the lens and reach the retina. Blue light will produce free radicals, which will lead to the decline of retinal pigment epithelial cells, and the decline of epithelial cells will lead to the lack of nutrition of photoreceptor cells, resulting in visual damage. These "inappropriate lights" are the chief culprit of macular degeneration (AMD), a large part of senile blindness.
microwave radiation
The harm of electromagnetic waves to human eyes was reported as early as the 1950s. In the United States, it was reported that many people working in radar stations had cataract diseases, and there were more such reports in the 1970s. People's understanding of it is gradually profound, and the research on the harm of electromagnetic radiation to human body has also entered a period of rapid development.
In 1980s, China began to study the influence of electromagnetic waves on living things. The Research Report on the Harm of Microwave Radiation to Human Eyes points out that the lens of human eyes contains only a few blood vessels and is not easy to carry too much heat. However, its dielectric constant and conductivity are very high, and the microwave power entering the eyeball decays quickly, which shows that the eyeball has strong absorption characteristics of microwave power. From the biological mechanism analysis of radio frequency electromagnetic radiation, under the action of electric field, it is rearranged after polarization. In this process, collision and friction produce a lot of heat. In addition, the ions in organs move and vibrate at high speed under the action of electric field, which makes the electrolyte hot. In a certain range, the shorter the wavelength, the more energy is absorbed. When the wavelength is equal to 3 cm, it can absorb 98% energy. In this way, the local or whole body temperature of the body can be increased. The greater the power density of electromagnetic radiation, the greater the energy absorbed by biological tissues and the greater the electromagnetic harm caused.
Because the eyes are exposed in microwave and have strong microwave absorption characteristics, the absorbed microwave electric energy becomes heat energy, and when the microwave power increases to a certain limit, the eyes will be damaged. Mild injury, feeling tired, dry eyes; Moderate injury makes the lens turbid and reduces vision; Under severe damage, changes in the lens of the eye lead to cataracts, complete loss of vision and blindness. Therefore, people working in microwave environment, especially those working in radar system, should pay attention to eye protection. When working, we should strengthen protective measures, wear shielding clothing, shielding cap and shielding glasses to reduce the stay time in strong field and prevent the damage of microwave radiation to eyes.
③ Influence on pregnant women
Qualified computers will pass the electromagnetic radiation test, and generally there should be no major problems. Of course, this does not include people who spend a lot of time on the computer every day. The developing fetus, especially in the first three months of pregnancy, is in the process of forming fetal organs. In the latest revision on computer screens and workers' health, the World Health Organization pointed out that pregnant women who use computers for more than 20 hours a week may have an impact on fetal development. So I personally suggest that if possible, it is best to suspend this kind of work during pregnancy.
3. Avoidance method
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 It is found that the radiation generated by the computer will affect the development of the fetus, which will seriously cause fetal malformation. Keep a good working environment indoors, such as comfortable temperature, clean air, suitable negative ion concentration and ozone concentration;
(3) The light in the computer room should be appropriate, not too bright or too dark, so as to avoid interference light caused by direct light irradiation on the 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 a computer to radiate 4.
Computer radiation 4
Glass or high quality plastic filter;
⑤ Pay attention to keep the 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.
⑥ Pay attention to supplement nutrition. Computer operators working in front of the screen for too long will consume rhodopsin on the retina, which is mainly composed of vitamin A. Therefore, computer operators should eat carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal livers, 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;
⑦ Computer placement is very important. Try not to let the back of the screen face the place where people live, because the back of the computer has the strongest radiation, followed by the left and right sides, and the front of the screen has the weakest radiation;
We should adjust the brightness of the screen when using the computer. Generally speaking, the brighter the screen, the stronger the electromagnetic radiation, and vice versa. But it can't be too dark, so as not to affect the effect because of low brightness, which is easy to cause eye fatigue.
4. Radiation-proof food
Recommend some Chinese herbal medicines with homology of medicine and food that can prevent radiation, which can be used for making tea or cooking.
① Chrysanthemum
Chrysanthemum is sweet, bitter and slightly cold; Has the effects of dispelling pathogenic wind, clearing away heat, clearing liver-fire, improving eyesight, removing toxic substances and diminishing inflammation. It has certain curative effect on dry mouth, intense fire and eye astringency, and can make the symptoms of eye fatigue subside and restore vision. For office workers who often work overtime and stay up late, they can drink more. Chrysanthemum can also protect against radiation. If you spend a long time in front of computers and mobile phones, you can drink more chrysanthemum tea, which can resist the radiation of computers. However, chrysanthemum is cold, so drinking alone is not recommended. It is suggested that chrysanthemum tea made of Lycium barbarum and mulberry leaves can effectively relieve radiation for a long time.
② Fructus Lycii
Lycium barbarum is flat and sweet. Long-term consumption has the effects of tonifying kidney and liver, benefiting eyesight, strengthening bones and muscles, eliminating low back pain and prolonging life. Especially for middle-aged and elderly people with kidney deficiency, it is most suitable for eating and can make tea for a long time. For example, "Materia Medica Xuan Tong" records: "Lycium barbarum, tonifying kidney and essence, strengthens water and bones, while thirst, dizziness, backache and knee pain all heal themselves." Lycium barbarum is rich in carotene, vitamins, calcium, iron and other nutrients necessary for healthy eyes, so it has the function of improving eyesight, commonly known as "improving eyesight".
③ Mulberry leaves
Mulberry leaves have the effects of dispersing wind and heat, clearing lung-heat, moistening dryness, clearing liver-fire and improving eyesight. Modern medical research shows that mulberry leaves contain a variety of amino acids and vitamins. Mulberry leaves picked by frost in the early autumn, that is, autumn mulberry, are the best. At this time, mulberry leaves contain the most effective components such as rutin and chlorogenic acid, and the effect is also the best. Mulberry leaves have the effects of reducing blood lipid, cholesterol, thrombosis and atherosclerosis, anti-aging and anti-fatigue. Mulberry leaves also have a good skin care effect, especially on acne and brown spots on the face.
④ Mulberry
Commonly known as mulberry fruit. Has the functions of nourishing liver and kidney and nourishing yin. For example, "Southern Yunnan Materia Medica" said: "Mulberry benefits kidney and strengthens essence. Long-term use will turn black and improve vision. " Wang Qing Meng Ying also said: "Mulberry nourishes liver and kidney, and enriches blood." Therefore, people with kidney deficiency, especially those with insufficient kidney yin, are best to eat. Mulberry is called "folk sacred fruit", which is rich in active protein, vitamins, amino acids, carotene, minerals and other ingredients. Mulberry can nourish yin and replenish blood, promote fluid production and moisten intestines, and can be used for chronic physical weakness, liver and kidney yin deficiency, soreness of waist and knees, dark eyes and tinnitus.
⑤ buckwheat tea
"Compendium of Materia Medica" records that tartary buckwheat is bitter in taste, cold and flat in nature, benefiting qi, refreshing, benefiting eyes and ears, and has the functions of lowering qi, relaxing intestines and strengthening stomach. Modern clinical observation shows that tartary buckwheat powder and its products have the functions of lowering blood sugar, lowering blood fat and enhancing human immunity, and are used for adjuvant treatment of patients with diabetes, hypertension, hyperlipidemia, coronary heart disease, stroke and so on. Improve the circulation of the heart and brain, remove the garbage in the body, eliminate fatigue and restore energy. Dietary fiber in coarse grains can increase skin antioxidant function and make skin healthy and shiny, beauty beauty. The rare coarse grain dietary fiber in tartary buckwheat can balance the distribution of gastrointestinal nutrition and effectively treat constipation.
6 kelp
Kelp is the "nemesis" of radioactive substances, which contains a substance called kelp colloid, which can promote the excretion of radioactive substances invading the human body from the intestine. The latest research found that kelp extract can improve human immune function, isotope and radiation damage, inhibit immune cell apoptosis, thus playing an anti-radiation role.
All landowners honeysuckle
Honeysuckle has the effects of clearing away heat and toxic materials, expelling wind and clearing heat, cooling blood to stop dysentery, reducing blood and fire, relieving sore throat and benefiting diaphragm. It can be used for treating fever, fever, bloody dysentery due to toxic heat, carbuncle swelling, scrofula, hemorrhoid and leakage. The smell is fragrant and the taste is light and bitter. Honeysuckle is cold and sweet, and enters the lung, heart and stomach meridians. It has the effects of clearing away heat and toxic materials, resisting inflammation, tonifying deficiency and treating wind, and is mainly used for treating fullness, fever, heat toxic carbuncle, tumor and other diseases. It has certain curative effect on dizziness, thirst, mumps, suppurative tonsillitis and other diseases. At the same time, honeysuckle tea can also inhibit and kill pathogenic bacteria in the throat, and has anti-infection effect on the elderly and children. Therefore, taking honeysuckle soaked or decocted frequently is beneficial to the treatment and rehabilitation of wind-fire and red eyes, sore throat, obesity, liver-heat syndrome and liver-heat hypertension.
Step 5 avoid radiation
① Replace the desktop with a notebook computer.
Yes, you'd better get rid of the desktop at home as soon as possible, because research shows that the radiation of desktop chassis is far greater than that of notebook computers.
And you don't have to worry about the laptop being slower than the desktop, and the display screen being smaller than the desktop. All kinds of ultra-high quality notebook computers emerge one after another, and the display screen is large enough. If it really doesn't work, you can also connect an external monitor.
But I also want to remind you that it is best not to turn on the laptop while charging, because the live transformer is the main radiation source, so it is best to unplug the laptop after it is fully charged. In addition, don't put your notebook on your lap, which will only make you closer to the computer and more vulnerable to radiation.
② Clean the computer screen every day.
Before using the computer every day, wipe the computer screen with special liquid crystal cleaning liquid to remove the dust attached to the screen due to static electricity.
Because those tiny particles attached to the screen will increase the amount of radiation.
③ Put a bottle of hydroponic plants in front of the computer desk.
Put a bottle of hydroponic plants in front of the computer desk, whether it is rich bamboo or green radish. Green leaves can relieve visual fatigue.
④ Stand once every 1 hour for 10 minute.
Sitting in front of the computer for a long time without exercise will not only affect the blood circulation and lymphatic circulation of the whole body, but also lead to slow metabolism, accumulation of metabolic waste in the body, edema of limbs and sore eyes.
What you didn't expect is that the cerebral cortex will also feel tired and it is difficult to work at its best.
⑤ Wash your face every 3 hours.
Did you find it? The closest thing to the computer screen is your face.
Because the tiny facial pores are easily blocked by particles gathered around the computer because of static electricity, the skin can only make the pores bigger and bigger in order to continue breathing, which leads to the facial skin becoming rougher and rougher, and acne often grows, which is certainly not the result you want.
So I suggest you wash your face every 3 hours, clean your skin, and then carefully apply moisturizer to moisturize your skin.
Step on two golf balls.
When sitting in front of the computer to work, step on two golf balls and roll on the ground in a small area while working.
This can not only prevent you from sitting cross-legged, but also help you to move your legs at any time, prevent edema of lower limbs, stimulate acupoints on the soles of your feet and help you lose weight.
⑦ Adjust the brightness of the computer screen.
Turn down the computer screen to reduce the irritation to the eyes. It would be better if you could wear a pair of radiation-proof glasses.
⑧ Move your wrists at any time.
Take time to exercise your wrist at any time between work. Put your palms together, cause fever through mutual friction, then make a fist with your fingers crossed, and then quickly stretch your little finger, ring finger, middle finger and index finger in turn. Repeating 10 times will promote the blood circulation of the wrist, relieve the stiff state and effectively prevent the "mouse hand".
In addition, you can also drop a drop of lemon essential oil on your palm in advance, so that when the palms rub against each other and heat up, the fragrance of lemon essential oil will be emitted, which has a refreshing effect.
Pet-name ruby prepare a high-quality work chair.
Since you have to spend a lot of time in front of the computer, of course you can't abuse yourself. You must prepare a high-quality work chair for yourself.
After trying it, you will immediately find the benefits of a good chair. It can not only help you lose weight by sitting in a sitting position, but also effectively relieve the pressure on your waist, abdomen, shoulders and back, and effectively prevent the pain in your waist, abdomen and shoulders and back.
If the working atmosphere is relaxed, it is a great choice to replace the working chair with a fitness ball!
Attending to move neck and shoulders at any time.
Another thing to pay special attention to when working in front of the computer is to move your neck and shoulders at any time.
Doing head rotation and shoulder encircling can prevent "neck and shoulder diseases" caused by long-term computer use.
At the same time, it can also effectively exercise the neck and shoulder muscles. You know, if the neck and shoulder muscles lack exercise, the skin will easily relax and get old!
Eat more pomegranate
The latest medical research of Michigan State University found that ellagic acid contained in pomegranate can effectively prevent human cells from being damaged by ionizing radiation.
Therefore, when you sit in front of the computer and work every day, you might as well prepare yourself a fresh pomegranate for dinner. Of course, a cup of freshly squeezed pomegranate juice is equally effective. Stop drinking carbonated drinks. Wouldn't it be better to lose weight with a cup of freshly squeezed juice rich in vitamins?
Eat more bananas.
If you have to sit in front of the computer for a long time every day, I suggest you eat 1 banana every day.
Bananas are rich in mineral potassium, other trace elements and vitamins, which can help you effectively relieve eye cell fatigue. Moreover, bananas can also provide a good feeling of fullness, so that you don't want to eat snacks, which has the effect of preventing obesity.
