What harm does radiation do to the human body?

Radiation hazards

1, computer radiation affects the human nervous system, regular use of computers will make people have headaches, insomnia, dreams, hair loss, memory loss and other symptoms; will also harm the skin, eyes, endocrine system, reproductive system, nervous system, and even cause leukemia, cataracts and cancer. Computer radiation is particularly harmful to women and children. Women due to physiological reasons, the regular use of computers can lead to menstrual disorders, infertility, facial spots, miscarriage, fetal malformation. Children are in the period of physical development, regular use of computers will lead to children's retinal damage, vision loss, memory loss, mental development is not normal, pediatric leukemia, etc., a serious threat to the normal growth and development of children.

2, electromagnetic radiation harm to the human body mechanism is mainly thermal effect, non-thermal effect and cumulative effect.

Thermal effect: more than 70% of the human body is water, water molecules by electromagnetic radiation friction, caused by the body temperature. This affects the normal work of the organs in the body.

Non-thermal effect: the organs and tissues of the human body there is a weak electromagnetic field, they are stable and orderly, once the interference of the external electromagnetic field, in a state of equilibrium of the weak electromagnetic field is about to be destroyed, the human body will also suffer damage.

Cumulative effect: thermal and non-thermal effects on the human body after the role of the human body has not had time to repair the damage to the human body before (usually referred to as the human body's ability to withstand - internal resistance), and then again by the electromagnetic radiation, the extent of the damage will occur cumulatively, and in the long term, will become permanently sick, endangering health.

▲Vision Hazard: The use of computers, the eyes are most vulnerable to infringement, especially easy to cause teenagers myopia and ciliary muscle spasm. These are known as "computer vision syndrome" is a stress-induced disease, the reason is that the eyes are staring at a place for a long time, the number of blinks is only one-third of the usual, thus reducing the secretion of lubricant in the eye. This reduces the production of lubricant in the eye. Long-term effects such as eye fatigue, double vision and blurred vision can also lead to other discomforts. You should blink more in front of the screen to increase the secretion of tear glands and moisturize your eyes. The most effective way is to take proper rest and eat more food containing vitamin A to replenish the retinal retinal retinas, such as carrots, cabbages, bean sprouts, tofu, jujubes, oranges, milk, eggs, animal livers, lean meat and so on.

▲Tissue damage: the repetitive and tense movements of operating a computer can damage certain parts of the muscles, nerves, joints, tendons and other tissues. In addition to low back pain, those suffering from carpal tunnel syndrome, in addition to wrist pain or even paralysis, these symptoms will extend to the palm of the hand and fingers. More exercise is the most effective way to overcome this computer occupational disease. The amount of exercise does not need to be too large, walking, lifting dumbbells and light aerobic exercise, can receive good results. The important thing is to be persistent. Change your position often and avoid working in one position for a long time. Adjust the table and chair to the height that suits you. The correct height should be: sitting in a chair, elbows and keyboard line should be parallel to the ground, the computer fluorescent screen should be placed in your line of sight a little lower, to ensure that when you look at the fluorescent screen, the neck slightly tilted upward, do not look up; feet should be placed flat on the ground, the chair should be smooth, the back feels comfortable.

▲Respiratory hazards: The gases emitted by computers can harm the respiratory system. The British Allergy Foundation researchers recently published a study that office equipment will release harmful ozone gas, the main culprit is the computer, laser printers, and so on. These ozone gases are not only toxic, but can cause breathing problems for some people. For those with asthma and allergies, the situation is even more serious. In addition, staying in places with high concentrations of ozone gas for longer periods of time can lead to lesions in the lungs. Computer rooms should be ventilated by opening windows and doors frequently and placing small air fresheners or green plants near your seat to improve indoor air quality. Printers also produce irritating gases that irritate the nose and airways, and prolonged exposure should be avoided.

Drinking green tea can prevent computer radiation

Computer radiation is not only harmful to human health, but also affects the quality and efficiency of work. For people who live a stressful and busy life, the easiest way to ward off computer radiation is to drink 2 to 3 cups of green tea and eat an orange every morning. Tea is rich in vitamin A original, it is absorbed by the body, can be quickly converted into vitamin A. Vitamin A not only can synthesize retinol, but also can make the eyes in the dark light to see things more clearly, so green tea can not only eliminate the hazards of computer radiation, but also to protect and improve eyesight. If you are not used to drinking green tea, chrysanthemum tea can also play a role in resisting computer radiation and regulating body functions.

Help you reduce computer radiation

Technicians said that computer radiation is inevitable, but can be reduced. First of all, should be as far as possible to buy new models of computers, generally do not use the old computer, the old computer radiation is generally more powerful, in the same distance, the same type of model conditions, generally 1-2 times the new computer. Operation of the computer is best in the display on a computer special color filter to reduce the harm of radiation, do not place indoor idle metal objects, so as not to form the re-emission of electromagnetic waves. When using the computer, to adjust the brightness of the screen, in general, the greater the brightness of the screen, the stronger the electromagnetic radiation, and vice versa, the smaller. However, can not be adjusted too dark, so as not to affect the effect of too little brightness, and easy to cause eye fatigue. Also note that the screen to maintain an appropriate distance. The closer the screen, the greater the electromagnetic radiation suffered by the human body, so the better is half a meter away from the screen.

Computer radiation damage to the skin, wash your face after the computer

Computers are becoming more and more essential supplies for work, dermatologists recently reminded that daily operation of the computer, after the computer must wash your face. The body and the computer screen should be as far as possible to maintain a distance of not less than 70 centimeters.

The amount of radiation generated by the computer screen is very small, but the accumulation of time will still damage the skin, easy to produce facial discoloration, the skin around the eyes appears slack, crow's feet, bags and dark circles under the eyes. City dermatology hospital experts reminded frequent computer users, especially women, in the machine before it is best to apply some protective products, such as isolation cream or foundation. At the same time, it is best to use computer protection screen. After using the computer, it is best to wash your face often. Because long time in front of the screen, the skin is also prone to excessive oil secretion, dust accumulation. Before going to bed, after using the computer more need to clean the skin in a timely manner.

Computer radiation damage in the keyboard

Do you often feel heavy head or memory loss?

When you sleep on your stomach, remember to turn off your computer, not just your screen. Because turning off the screen alone won't eliminate radiation, and because we all sleep on our stomachs with our heads directly in front of the computer, it's too late to get Alzheimer's or a brain tumor.

You often sit at a computer desk, whether you sit for hours and hours and sit in an incorrect posture, always feel inexplicable shoulder and neck pain, and even distracted by work? Now please do a small test, please look to the left direction, and then head 45 degrees down slowly bent, action to do here, your neck, neck and shoulder whether you feel abnormal pain? If you have the above symptoms, you have to be careful, because you are likely to have a modern computer civilization disease - "thoracic outlet syndrome".
