Why is it easy to generate static electricity in winter?

The reasons why static electricity is easily generated in winter are: 1, the weather is relatively dry, so the insulation resistance between objects is large, and it is easy to accumulate charges on poor conductors such as clothes; In winter, people wear a lot of clothes, and most fibers, especially chemical fibers, are poor conductors and insulators. When people are active, they drive the friction between these clothes and the human body, resulting in static electricity gathering on the clothing fibers. When the voltage reaches a certain intensity, they "break through" the original insulation (such as air) to discharge, so people are easily "shocked".

In order to prevent the occurrence of static electricity, we should maintain a certain humidity indoors, such as mopping the floor frequently, sprinkling water, or humidifying with a humidifier, or hanging some old towels with good water absorption next to the heating equipment, so that the indoor air always contains a certain amount of water; Take a bath and change clothes frequently to eliminate the static charge accumulated on the surface of human body. When combing your hair, first immerse the comb in water to eliminate static electricity; Touch the wall with your hands after undressing, and touch the wall with your hands before touching the door handle or faucet to "discharge" the static electricity in your body. For the elderly, we should choose soft and smooth cotton or silk underwear and try not to wear chemical fiber clothing to minimize the harm of static electricity.
