Static electricity is a kind of electrostatic charge. In dry and windy autumn, people often encounter this phenomenon in their daily life: when they take off their clothes and sleep at night, they often hear crackling sounds in the dark, accompanied by blue light. When they meet and shake hands, as soon as their fingers touch each other, they will suddenly feel the sting of their fingertips, which is shocking; When you get up in the morning to comb your hair, it tends to "float". The more you manage, the more chaotic it is. When you pull the door handle and turn on the tap, you will get an electric shock, and you will often make a "bang, bang" sound. This is static electricity generated in the human body.

Secondly:

Friction in daily life is essentially a process of constant contact and separation. In some cases, static electricity can be generated without friction, such as induced electrostatic electrification, thermoelectric and piezoelectric electrification, Helmholtz layer, jet electrification and so on. Any two objects with different materials will generate static electricity after being separated, and the common method to generate static electricity is friction electrification. The better the insulation of the material, the easier it is to generate static electricity. Because air is also composed of atoms, it can be said that static electricity may be generated at any time and place in people's lives.

Once again:

Anti-static in daily life

1. Wash your hands before going out, or wipe your hands on the wall to eliminate static electricity. Try not to wear chemical fiber clothes.

2. In order to avoid static electricity, you can use small metal devices (such as keys) and cotton cloth to touch doors, door handles, faucets, chair backs, bed railings, etc. To eliminate static electricity, and then touch them with your hands.

3. Wear cotton underwear.

4. When getting ready to get off, hold the gear with your right hand, then touch the iron part below with your finger, then open the door, put your left hand on the iron part of the door, but don't let go of your left hand, and then let go of your right hand to get off. At this time, hold the door with your right hand to avoid electric shock.

We can take "prevention" and "release" measures to deal with static electricity. "Prevention", we should try to choose pure cotton products as fabrics for clothes and home decoration, and try to avoid using chemical fiber carpets and furniture with plastic as surface materials to prevent friction and electrification. Try to stay away from TV, refrigerator and other electrical appliances to prevent induction electrification. "Discharge" is to increase humidity and make local static electricity easy to release. When you turn off the TV and leave the computer, wash your hands and face immediately, so that the electrostatic charge on the skin surface can be released in the water. Try to choose high moisturizing cosmetics in winter. Commonly used humidifier. Some people like to keep ornamental fish and daffodils indoors, which is also a good way to adjust indoor humidity.

In addition, an economical and practical humidification method is recommended: put a basin of water under the heating, use an old towel (or absorbent cloth), put one end in the water and the other end on the heating, so that about three liters of water can be evaporated into the house day and night. If every heater does this, the whole room will feel damp and pleasant. it wont hurt you to try it

6. Taking a bath and changing clothes often can effectively eliminate static electricity accumulated on the surface of human body.
