What are the hazards of electromagnetic waves to human body?

1. Harm to the central nervous system The nervous system is very sensitive to electromagnetic radiation. After repeated exposure to low intensity, the function of the central nervous system changes, and neurasthenia syndrome appears, mainly manifested as headache, dizziness, fatigue, memory loss, sleep disorder (insomnia, dreaminess or lethargy), daytime dozing, irritability, sweating, palpitation, chest tightness, hair loss and so on. Hyperhidrosis and memory loss are particularly prominent. All these indicate that the brain is dominated by the inhibition process. Therefore, in addition to the above symptoms, the victim also showed short-term memory loss and prolonged visual motor reaction time. The poor coordination between hand and brain shows that the speed of marking numbers is slow and there are many mistakes. 2. Damage to the immune function of the body reduces the body's resistance. Animal experiments and investigations on radiation exposure of people show that the percentage of bacteria swallowed by white blood cells and the number of bacteria swallowed by human body are reduced. In addition, the formation of antibodies in people exposed to electromagnetic radiation for a long time is obviously inhibited. 3. People who are affected by electromagnetic radiation often have hemodynamic imbalance, vascular permeability and tension decrease. Due to the influence of autonomic nerve regulation function, people often show bradycardia and a few show tachycardia. The victim's blood pressure fluctuates, starts to rise, then returns to normal, and finally appears hypotension; The decrease of R T wave voltage in ECG is the result of vagus nerve allergic reaction and myocardial malnutrition. p？ Q interval is prolonged and P wave is widened, which indicates that atrioventricular conduction is poor. In addition, people who are exposed to electromagnetic radiation for a long time will have cardiovascular diseases earlier, and it is easier to promote their occurrence and development. 4. Influence on the blood system Under the action of electromagnetic radiation, the peripheral blood picture may be unstable, mainly showing a downward trend and leukopenia. Erythropoiesis was inhibited and reticular erythropenia appeared. The health survey results of radar operators show that most people have leukopenia. In addition, when radio waves and radiation act on the human body at the same time, the impact on the blood system can be more obvious than a single factor. 5. Effects on reproductive system and heredity. People who have been exposed to ultrashort wave generators for a long time may have decreased function and impotence; Women have menstrual cycle disorder. Due to poor blood circulation of testis, it is very sensitive to electromagnetic radiation, and sperm production is inhibited, which affects fertility. It denatures the egg cells, destroys the ovulation process and makes women lose their fertility. High-intensity electromagnetic radiation can produce genetic effects, causing chromosome aberration and abnormal mitosis in testis. Pregnant women receive short-wave diathermy treatment in the early stage or before pregnancy, which leads to congenital birth defects (deformed babies) in their offspring. 6. Influence on the visual system The eye tissue contains a lot of water, which is easy to absorb electromagnetic radiation power, and the blood flow of the eye is small, so the temperature of the eyeball is easy to rise under the action of electromagnetic radiation. Rising temperature is the main condition leading to cataract. The increase in temperature leads to protein condensation of the lens of the eye. Most scholars believe that the long-term effect of low-intensity microwave can accelerate the aging and opacity of lens, and may shorten the colored field of vision, prolong the dark adaptation time, and cause some visual obstacles. In addition, the long-term effect of low-intensity electromagnetic radiation will promote visual fatigue. 7. Carcinogenesis and Carcinogenesis of Electromagnetic Radiation Most experimental animals can increase the incidence of cancer after microwave treatment. Experiments by some microwave biologists show that electromagnetic radiation can promote chromosome mutation and mitosis in human body, leading to pathological proliferation of some tissues. Turn normal cells into cancer cells. The long-term exposure of American embassy staff abroad to high electromagnetic radiation from microwave eavesdropping leads to an increase in the white blood cell count of embassy staff and a higher incidence of cancer than normal people. Another example is that in areas affected by high-power long-range microwave radar, after investigation, the number of local cancer patients has increased sharply. The heating effect of microwave on human tissue can be used not only for physical therapy, but also for treating cancer and raising the temperature of cancer tissue center. It destroys the proliferation of cancer cells. In addition to the above health hazards, electromagnetic radiation also has adverse effects on endocrine system, hearing, substance metabolism and morphological changes of tissues and organs. Electromagnetic waves are so terrible, how should we guard against them? (1) unplugging can prevent electromagnetic waves: when electrical appliances are not in use, it is best to unplug them to avoid the indoor environment from being invaded by electromagnetic waves. (2) Keeping a distance can reduce electromagnetic waves: Yes, the farther the distance, the weaker the electromagnetic wave intensity. Therefore, when using computers, televisions, electric fans, hair dryers, microwave ovens, induction cookers and other electrical appliances, we should stay away from these electrical appliances to ensure safety. Computers and televisions have entered thousands of households, becoming people's mentors and friends, and indispensable partners for children, teenagers and young people. No matter men, women and children, almost everyone can't live without computer TV. While enjoying the happiness and happiness brought by her, people have also been hurt by an invisible killer and paid a heavy price. Computer monitors and TV screens will radiate some rays harmful to people's eyes and body, such as ultraviolet rays, high-energy photons, X-rays and other radiation-causing rays, which will affect people's eyes and health. (1) These rays kill the visual cells of human eyes, damage the visual nerve and central nervous system, cause vision loss, eye pain, and cause many eye diseases such as cataracts. (2) These rays will accelerate the aging of facial skin, produce spots and papules, lead to sarcoma sclerosis, and affect people's appearance and image. (3) These rays will stimulate the nerve center, affect sleep and lead to high blood pressure. (4) These rays will reduce white blood cells and reduce the body's resistance and immunity. (5) These rays will make people's mood fidgety, endocrine disorders and various functional disorders decline. Soft and pleasing computer video screen can eliminate the damage caused by various rays and create a comfortable, soft and warm environment for you; Protect your eyes and nerves; It not only makes you healthy, but also makes you happy. She is an environmental protection product to prevent light pollution, which is suitable for computer workers, especially children and teenagers. It can make them have bright eyes and a relaxed and happy mood and ensure their healthy growth. Usage: Hang the soft and pleasing computer video screen on the computer and TV screen, and hang the small hook on the belt on the cooling hole of the computer and TV.
