What causes static electricity? How to avoid or eliminate static electricity? What causes static electricity?

In winter, we often encounter this phenomenon: we get up in the morning and comb our hair, but the more we comb it, the more messy it becomes, and we may even get "angry"; when friends meet, they feel like bees as soon as each other's fingertips touch each other. It stings like a sting; you turn off the lights at night and take off your clothes to get ready for bed. Sometimes you hear crackling sounds in the dark, accompanied by blue flashes... These phenomena are all the result of static electricity "stimulation". Static electricity is invisible and intangible. It adheres to the surface of objects and releases energy only when it interacts with other objects. The human body generates static electricity mainly due to two reasons: one is dry air; the other is non-conductive chemical fiber clothing. Especially in winter, people will feel that the static electricity on their bodies is relatively large. This is because the climate in most parts of my country is very dry in winter, and the dry environment is more conducive to the accumulation of static electricity. Research shows that any two objects of different materials will generate static electricity when they come into contact. Therefore, when we move, the static electricity on our bodies is mainly caused by the friction between clothes or between clothes and the body. Moreover, clothes made of different materials are "charged" differently. For example, clothes made of chemical fibers are more likely to generate static electricity, while clothes made of cotton generate less static electricity. There are also dense high-rise buildings in modern cities. Most of the houses are made of reinforced concrete. In addition, a large number of electrical facilities are used, and indoor static electricity accumulation is not easy to release. All of these can produce powerful static electricity, making people live in more difficult conditions. Surrounded by increasingly strong static electricity. Although experiments have proven that people will not feel uncomfortable when the electrostatic voltage is 50,000 volts, static electricity does have many negative effects on human health. For example, excessive static electricity accumulation in the human body can affect the central nervous system, causing symptoms such as dizziness, headache, insomnia, and irritability. Another example is that some people with arrhythmia cannot find organic disease and the cause of the arrhythmia. However, after following the doctor's advice and wearing pure cotton clothes, the heart rhythm quickly returns to normal. In addition, a large amount of electrostatically adsorbed floating dust is mixed with a variety of pathogenic bacteria, and it is very easy to spread infectious diseases such as influenza, hepatitis, and tuberculosis. So, how to eliminate static electricity and avoid static electricity damage in daily life? To deal with static electricity, we can start from two aspects: "prevention" and "release". Let’s first talk about how to “prevent” static electricity. We should try to use pure cotton products as fabrics for clothes and home accessories, and try to avoid using chemical fiber carpets and furniture with plastic surface materials to prevent frictional electrification. Keep as few electrical appliances as possible in the bedroom to prevent induction electrification. In addition, pay attention to frequent ventilation indoors. "Put" means to increase the humidity so that local static electricity can be released. The static electricity accumulated in the body can be consumed through output. For example, walk barefoot indoors and let your feet touch the ground directly to release the static electricity accumulated in the body; wash your hands before going out, or put your hands on the wall to remove static electricity before opening the door; when you turn off the TV or leave the computer, you should Wash your hands and face immediately to allow the static electricity on the skin surface to be discharged in the water. In addition, in winter, using a humidifier to maintain indoor humidity is also a good way to release indoor static electricity. In addition to using a humidifier, raising ornamental fish and daffodils indoors can also adjust indoor humidity and help release static electricity. In the house, static electricity may be generated by friction between the carpet and the soles of shoes, and outside the house, the wind may also cause the body to become electrified. At this time, when you touch the iron door when entering or exiting, you are likely to get electric shock on your hands. Therefore, when touching an iron door, do not touch the iron door directly with your hands. Instead, first let your hands grasp a bunch of keys in your pocket over a large area (usually this will not cause static electricity stimulation), and then, use a key Touch the tip of the iron door to the iron door, so that the static electricity on your body will be discharged. It is also common to be stimulated by static electricity when getting out of a taxi. This is mainly due to the accumulation of static electricity caused by the friction between the body and the seat when getting off the bus. When closing the door after getting off the bus, if the hand suddenly touches the iron door, it will be stimulated by static electricity. Therefore, it is best to hold the metal door frame in advance before your body completely leaves the seat, so that you can discharge the static electricity from your body at any time, and avoid the sudden generation of static electricity when you touch the iron door after getting off the car. Finally, I would like to remind everyone that frequent bathing and changing clothes can effectively eliminate static electricity and charged dust accumulated on the surface of the human body. Eating more vegetables, fruits, yogurt and other foods, drinking more water, and paying attention to supplementing calcium and vitamin C can also reduce the adverse effects of static electricity on the body.
