What are the hazards of static electricity to the human body?
There are often static phenomena in daily life, so what harm does static electricity have on the human body? The static interference generated by the human body can change the normal potential difference of the human body surface, and affect the normal electrophysiological process of the myocardium and the normal conduction of the electrocardiogram without interference. This kind of static electricity can make the patient aggravate the condition or induce premature beats. The long-lasting static electricity will also increase the alkalinity of the blood, causing the calcium content in the serum to decrease, and the excretion of calcium to increase, causing itching and pigmentation of the skin, affecting people. The body's physiological balance, interferes with people's emotions.
The harm of static electricity: Many computer workers have facial erythema, pigmentation, and other facial diseases. The static electricity generated by the computer screen attracts a large amount of suspended dust, which causes the face to be stimulated. In addition, because the skin of the elderly is relatively dry compared with young people, coupled with factors such as aging of the cardiovascular system and weakened anti-interference ability, it is more susceptible to static electricity and causes cardiovascular disease.
The harm of static electricity is that the air in the winter is too dry, and static electricity is easily generated between human skin and clothing. The high static voltage can reach tens of thousands of volts, causing discomfort. Some people have investigated and measured the static electricity generated in daily life. Walking on the carpet can generate 1500~35000 volts of static electricity. When walking on the vinyl resin floor, it can generate 250~12000 volts of static electricity. The indoor buttocks will be on the chair. Generates static electricity above 1800 volts. The level of static electricity depends mainly on the humidity of the surrounding air. Usually, if the static interference exceeds 7000 volts, people will have a shock. Relevant information shows that static electricity is very harmful to the human body.
Long-lasting static electricity can increase the alkalinity in the blood, reduce the calcium content in the serum, and increase the amount of calcium excretion in the urine. This is an increase in the blood calcium level in children who are growing and developing, and the need for calcium. Pregnant women and nursing mothers are undoubtedly worse. Excessive static electricity builds up in the human body, and it also causes abnormal conduction of current in the nerve cell membrane of the brain, affecting the central nervous system, leading to changes in blood pH and oxygen characteristics of the body, affecting the physiological balance of the body, causing dizziness, headache, irritability, and insomnia. , loss of appetite, mental paralysis, and other symptoms. Static electricity can also interfere with human blood circulation, immunity, and the nervous system, affecting the normal operation of various organs (especially the heart), which may cause abnormal heart rate and premature beats. In winter, about one-third of cardiovascular disease is associated with static electricity. Inflammable and explosive areas, static electricity in the human body can also cause fires.
