When you feel the electric shock, the electrostatic voltage on your body has exceeded 2000 volts; When you see the spark, the electrostatic voltage on your body has exceeded 3000 volts; Hearing the "bang" discharge sound, the electrostatic voltage on my body is as high as 7000~8000 volts.
Will static electricity hurt me?
If static electricity accumulates to a certain voltage, people will get an electric shock when they touch it. For example, when the electrostatic voltage reaches 2000 volts, people's fingers will feel it; When it exceeds 3000 volts, the hand will tingle; When it exceeds 7000 volts, people will feel an electric shock. However, due to the short electrification time and small current, it will not cause danger to people.
From the perspective of traditional Chinese medicine, too strong static electricity in the human body is a harbinger of some disease hidden in the body. Excessive static electricity indicates insufficient body fluid, which is manifested as kidney deficiency. Drinking water alone can't replenish body fluids, so we should pay attention to it as soon as possible.
Experts warn that static electricity is not just a bad feeling. In fact, it has a negative impact on people's health, so we should take appropriate precautions.
It has been proved by medical experts that skin electrostatic interference can change the normal potential difference of human body surface, affect the normal electrophysiological process of myocardium and the normal conduction of ECG without interference. This static electricity will aggravate the patient's condition or induce premature beats. Persistent static electricity will also increase the alkalinity of blood, and even lead to itching and pigmentation of skin, which will affect the physiological balance of human body and interfere with people's emotions.
How to prevent static electricity
Experts remind that after undressing, before touching the door handle or faucet, gently touch the wall with your hand to "discharge" the static electricity of the human body before working; Old people should choose to wear soft and smooth cotton underwear and underwear to minimize the harm of static electricity; Pay attention to maintain a certain humidity in the room, often mop the floor and sprinkle water. If possible, increasing air humidity with a humidifier can effectively prevent static electricity.
A dermatologist also told reporters that many office white-collar workers who operate computers every day are much more likely to suffer from facial diseases such as erythema and pigmentation than those who don't use computers. This is because the static electricity generated by the computer screen will attract a lot of suspended dust, causing facial irritation.
Air drying, static electricity is easy to hurt people.
Professor Jiang Jinqi, director of the emergency department of Shanghai Chest Hospital, told the reporter that many people now live in high-rise buildings, and the human body will absorb and accumulate electrostatic charges generated by various household appliances. In addition, indoor walls and floors are mostly insulators, so these people are more vulnerable to electrostatic interference.
For those who accumulate more static electricity in the body, it can be consumed by "output".
Professor Jiang introduced that people with more static electricity should wear less chemical fiber clothing, do not use chemical fiber carpets at home, and maintain a certain humidity indoors. For example, you can put a pot of cold water, or plant some potted plants indoors. In addition, avoid staying in a place with static electricity for a long time, such as the production room where computers gather. After using the computer or watching TV for a long time, wash your hands and face in time to "drive away" the static electricity on your skin.
