What is electromagnetic radiation?
A: Electromagnetic radiation in a broad sense usually refers to the electromagnetic spectrum. In a narrow sense, electromagnetic radiation refers to the radiation wave generated by electrical equipment, usually referring to the part below infrared.
What harm does electromagnetic radiation do to human body?
A: The mechanism of electromagnetic radiation endangering human body is mainly thermal effect, non-thermal effect and accumulation effect.
Thermal effect: More than 70% of human body is water, and water molecules rub against each other after being radiated by electromagnetic waves, which causes the body to heat up, thus affecting the normal work of other organs of the body.
Non-thermal effect: There are weak electromagnetic fields in human organs and tissues, which are stable and orderly. Once disturbed by external electromagnetic waves, the weak electromagnetic field in equilibrium will be destroyed, and the normal circulation function of human body will be destroyed.
Cumulative effect: after thermal and non-thermal effects act on human body, if the damage to human body is radiated by electromagnetic waves again before it can repair itself, the damage degree will accumulate and become permanent pathological or life-threatening. For groups exposed to electromagnetic radiation for a long time, even if the power is very small and the frequency is very low, unexpected lesions will be induced, so be alert!
Scientists from all over the world have proved through long-term research that long-term exposure to electromagnetic radiation will lead to decreased immunity, metabolic disorder, memory loss, premature aging, arrhythmia, decreased vision, abnormal blood pressure, acne and rough skin, and even lead to various cancers. The reproductive capacity of men and women is declining, and women are prone to menstrual disorders, abortion, teratogenesis and other diseases.
With the improvement of people's living standard, TV, computer, microwave oven, electric blanket, refrigerator and other household appliances are becoming more and more popular, and electromagnetic wave radiation is more and more harmful to human body. For example, electric blanket is the most widely used household appliance, which has the closest contact with human body, the longest contact time and the most serious harm to human body. At present, the electromagnetic radiation intensity of most electric blankets used by people exceeds the national standard by 20 ~ 100 times, which is extremely harmful to human health and should be paid attention to.
