The Newly Purchased Down Coat Makes A Crackle Sound.

"Every time I take off my new down jacket, I hear crackling noise. I hear it's static electricity. Is it harmful to people's health?

How can we eliminate it? "

Ms. Han from downtown calls for help.

In the morning, I comb my hair, but I comb my hair more and more. I go to work by bus and people are crowded. As long as two down coats are rubbed, I will call strangers. When I get off the train, I will close the door, and I will be shocked when I touch the iron door.

Reporter survey found that Miss Han reflected problems in our daily life often encountered.

How does static electricity produce harmful effects on human body and how to eliminate static electricity?

The reporters asked the experts to answer them and listen to what they said.

How does static electricity come into being?

The information that the reporter inquires through the network shows: when the human body moves, the friction between the skin and the clothes, and between the clothes and the clothes will generate static electricity.

Static electricity refers to the charge that does not flow.

There are several reasons for producing static electricity, the main reason is that air drying and clothing are not conductive.

This is because the skin surface is dry, and the resistance value increases, resulting in a large number of charges accumulated locally. Secondly, because of the clothes can not be exported, resulting in the accumulation of potential difference increases.

When the conditions are ripe, the body will suddenly release static electricity, so that people feel the electric shock and numb.

A teacher who teaches physics at fifth senior middle school explains that in general, in cold and dry winter, indoor air is drier and the phenomenon of static electricity is more prominent.

For example, when combing your hair in the morning, the more you comb, the more chaotic you are; when you go to work by bus and people are crowded, as long as the two down coats are rubbed, they will "call" with strangers. Even at night when they sleep off their clothes, the body will contact with the bedding when they are exposed to electricity.

Is static electricity harmful to human body?

According to experts from the Municipal Hospital of traditional Chinese medicine, the body itself has bioelectricity, such as electrocardiogram, electroencephalogram and electromyography, all of which are weak electrical energy and maintain organ function.

The magnetic field generated by static electricity can often change the inherent potential difference in the human body. For those with weaker cardiac function, the effect of static magnetic field can cause chest tightness, dizziness and shortness of breath.

Therefore, static electricity has a negative effect on people's health. In order to ensure good health and no worries, we must discharge in time and take proper precautions.

"Elderly people with cardiovascular diseases should pay special attention to the negative effects of static electricity."

How to eliminate static electricity in time?

"Timely discharge is the key."

The experts said that in order to prevent the occurrence of static electricity, indoor humidity should be kept. We must constantly mop the floor, sprinkle some water regularly, or humidifier to humidifier. We should bathe regularly and change clothes frequently to eliminate the static electricity accumulated on the surface of the human body.

When the hair is not combed, the comb is immersed in the water for a moment. After the static electricity is removed, the hair can be combed and served.

After taking off your clothes, gently touch the wall with your hands, touch the wall before touching the handle or faucet, and release the static electricity in the body, so that static electricity will not hurt you.

For the elderly, soft and smooth cotton or silk underwear and underwear should be chosen, so as not to wear chemical fiber clothing, so that the harm of static electricity can be reduced to a minimum.

The clothes made of pure cotton cloth do not produce static electricity. The clothes made of chemical fiber cloth are easy to generate static electricity.
