Why some people are particularly susceptible to static electricity

The air is dry, and the clothes rub against the **, so it is easy to generate static electricity, especially the clothes of chemical fibers are more likely to produce static electricity.

1. Because the person gets up from the chair, or wipes the wall and other processes (the initial charge separation occurs on the outer surface of clothing or other related objects, and then, the human body is charged by induction.

2. Because people walk on insulated floors such as carpets made of high resistivity materials (the initial charge separation occurs between the shoe and the floor, and then, for conductive shoes, the human body is charged by the transfer of electric charge; For insulated shoes, the human body is charged by induction).

3. Because of the static electricity when taking off the coat. This occurs when the contact between the outer and inner layers of clothing causes electricity, and the human body is charged by charge transfer or induction.

Static electricity on the human body is caused by the friction of clothing and other items on the human body against each other. Static electricity is generated because the nucleus does not attract enough electrons to the outer electrons, so that electrons are lost under the action of friction or other factors, thus causing the friction to have a negative charge. In the case of good insulation properties of frictions, these charges cannot be lost and will accumulate.

In addition, the capacitance of the insulator is extremely poor, resulting in a situation where the charge is not large but the voltage is high.

Clothing made of chemical fibres is more likely to generate static electricity, while cotton clothing produces less electricity. And because the dry environment is more conducive to the transfer and accumulation of electric charge, people will feel that the static electricity on their bodies is greater in winter.

Answer: In daily life, wearing chemical fiber clothing often causes static electricity to accumulate in the body after rubbing against the body, and when it suddenly touches metal, it will suffer the pain of electric shock, especially in winter when the climate is relatively dry. To prevent static electricity, you can use a humidifier to keep the indoor air humid, mop the floor frequently, and sprinkle some water indoors. In addition, take a bath frequently, change clothes, eliminate the static charge accumulated on the surface of the human body, eat more fresh vegetables and fruits, ensure daily water intake, and wear cotton clothes.

Static electricity is mainly contact static electricity, that is, when an uncharged object touches an object with static electricity, the charge moves from a high potential to a low potential, like water flowing to a low potential, so the uncharged object generates electricity.

Dry indoor is often a high-risk area of "electric charges", due to the low humidity of the air, chemical fiber clothing, carpets, cushions, wallpaper, etc. are rubbed, which will produce static electricity.

If you touch live water pipes, electrical appliances, metal doorknobs, TV screens, and even switches with your hands, you will feel like being "electrified", and you will feel numb and painful. If the static electricity accumulates to a certain voltage, the phenomenon of "electric shock" will occur when people come into contact with it. Although the voltage of static electricity is large, the resistance of the human body is also very large, and its current is small, and the energy it has is small, so it will not endanger human life.
