I don’t know if any of you have experienced being shocked by static electricity.
Although the current of static electricity is very small, you will still feel a sting when you are shocked.
Being electrostatically shocked
Just speaking from Okawa's own experience, will be electrocuted when touching the door handle, being electrocuted when turning the faucet, and sometimes even being electrocuted when someone touches it...
It's okay to be electrocuted until it hurts, but what many people don't know is that the harm of static electricity is far more than that, and the harm of static electricity can even be described as terrifying.
What on earth is going on?
Electrostatic discharge
In the content of this article, Dachuan will take you to understand why static electricity occurs frequently in winter? How terrible is static electricity?
What is static electricity?
From a physical point of view, static electricity is actually a kind of charge that is in a static state.
Charge
When charges accumulate on the surface of certain objects, static electricity (positive static electricity or negative static electricity) is formed.
When an object with static electricity comes into contact with or approaches a zero potential object, the charge on the surface of the object will be transferred. This charge transfer process will form an instantaneous current .
is often accompanied by the generation of arcs, and sometimes accompanied by a snapping sound.
The directional movement of charges forms a current
As early as middle school, we have been exposed to knowledge related to static electricity.
The most classic one is what the teacher said in class:
After the rubber rod rubs against the fur, the rubber rod will be negatively charged, and the fur will be positively charged.
The friction between rubber rods and fur will produce static electricity
In fact, in ancient my country, the ancients had already recorded static electricity.
During the Western Jin period, Zhang Hua once recorded this in " Natural History ":
When people today comb their hair and take off their clothes, there is light when combing and untying knots, and there is also a buzzing sound.
Static electricity is generated when combing hair
refers to the static electricity generated when combing hair and taking off clothes.
Why does static electricity appear frequently in winter?
Compared with other seasons, seasons like autumn and winter are more likely to generate static electricity. The reason why
is like this is actually very simple.
Static electricity is more likely to be generated in autumn and winter
Especially for friends who live in the north like Dachuan, you should all know that the autumn and winter seasons in the northern region are extremely dry.
A dry environment is also the "culprit" of static electricity.
Dry winter in the north
I have to mention a special physical property of static electricity:
The better the insulation of the "material", the easier it is to generate static electricity.
Our human body itself also belongs to this kind of "material". Based on the different humidity of the environment, the dryness of the surface of our human skin is different.
Human skin
The greater the dryness of human skin, the less conductive "moisture medium" will be, the greater the resistance will be, and the better the insulation of human skin will be.
Combined with what Okawa just mentioned, the special physical properties of static electricity, we can conclude that the drier the skin, the easier it is to generate static electricity.
The drier the skin, the more likely it is to generate static electricity
This also explains why it is easier to generate static electricity in seasons like autumn and winter, which is caused by dryness...
How terrible is static electricity?
Although it hurts to be shocked by static electricity, it is not the most terrifying thing about static electricity.
You may not believe it, the existence of static electricity sometimes even directly threatens our life safety .
static
Time goes back to On January 9, 2021, such a shocking safety accident occurred in a gas station in Shaoyang City, Hunan Province.
When a car was refueling, the car owner standing next to him saw a leaf at the mouth of the fuel tank and used his hands to clean it. However, as soon as the hand came close to the fuel tank, static electricity was generated. The static electricity instantly ignited the oil vapor at the mouth of the fuel tank, causing a flame.
The car caught fire as soon as the car owner touched it.
Fortunately, the staff at the gas station nearby had quick eyesight and quick hands to put out the flames with a fire extinguisher. Finally, a bigger accident was avoided.
If a fire breaks out in the entire gas station, the consequences will be completely disastrous.
On August 10, 2020, a fire and explosion occurred at a gas station in Russia.
Same accidents have occurred frequently across the country in recent years.
For example, The fire accident that occurred at a gas station in Jiangsu in 2014 was caused by static electricity.
Static electricity fire accident at Jiangsu gas station in 2014
A fire that occurred at a Tianjin self-service gas station was also caused by static electricity.

There are many similar accidents, and Dachuan will not give examples here.
Static electricity fire accident
In addition to causing major safety accidents such as fires, static electricity can also directly harm our health.
Scientific research has shown that persistent static electricity will have a certain impact on the health of pregnant women. will lead to a decrease in progesterone levels in their bodies, thus affecting their health during pregnancy.
Static electricity will have an impact on the health of pregnant women.
Not only that, If the intensity of static electricity stored in the human body is too high, it will also cause serious harm to the health of the heart and brain.
is particularly harmful to the heart, and is very likely to cause abnormal heartbeats and premature heart beats.
Static electricity harms heart health
It is understood that most patients with heart disease and neurasthenia whose causes cannot be found are most likely caused by long-term exposure to static electricity.
In winter, when the weather is dry and static electricity is more likely to occur, about 30% of cardiovascular diseases are related to static electricity...
is written at the end
After seeing this, everyone should have a new understanding of the dangers of static electricity.
Static electricity
So, at the end, it is necessary for Okawa to add more, How to avoid the generation of static electricity in life, especially in dry seasons like autumn and winter. How to avoid the generation of static electricity .
Controlling humidity at home is the key to avoiding the generation of static electricity. can be humidified through a humidifier to keep the home environment in a state that is not too dry and maintain the humidity of the skin. can effectively avoid the generation of static electricity.
Humidifier
Next, you need to pay attention to your clothes. Try to avoid wearing underwear made of chemical fiber.
Because the skin rubs against chemical fiber clothing, it is easier to generate a large amount of static electricity.
The friction between skin and chemical fiber clothing is more likely to generate static electricity
Of course, for safety reasons, is to avoid daily "electric shock".
Before touching metal objects such as door handles and faucets, you can "release" static electricity by touching small metal objects, such as touching metal zippers.
In this way, when you touch them again, you won't get "electric shock".
Touch the metal zipper
Finally, if you have any other effective ways to "anti-static".
