, as a severe victim of static electricity, has been electrocuted for more than ten years. Every winter, he is electrocuted to death. He often dare not touch the door handle. This year, he accidentally solved the static electricity problem. He deliberately wrote an article about his various experiences in detail, hoping to help more static electricity victims. If you just want to see the solution, you can go directly to Chapter 3. Be sure to read it carefully.
Chapter 1 Generation of Static Electricity
Why there is static electricity on people
Static electricity comes from the friction between objects. Static electricity on the human body generally comes from three types: friction between clothes, friction between clothes and foreign objects, and friction between clothes and skin.
When the outside air humidity is low (generally less than 30%), friction will easily generate static electricity, and it will continue to accumulate in the body, generating very high voltage static electricity, generally exceeding 10,000 Ford. When we touch metal objects next time, the static electricity will be released in an instant, and the skin at the discharge site will feel tingling. In severe cases, electric sparks can even be seen.
Friction between clothes
Whether people are walking, running, or getting up, as long as the body moves, friction will inevitably occur between clothes, such as between jackets and sweaters, and between pants and long johns. Friction will generate static electricity. Friction between clothes is also the most common source of static electricity. The amount of static electricity generated by different fabrics is very different.
Fabrics that are prone to static electricity are generally chemical fibers. The common ones are polyester ( polyester fiber ), acrylic (artificial wool), nylon (nylon).
When we buy clothes, we must carefully choose the fabric ingredients. The ingredients of the fabrics will be written on the labels of the clothes.
If you purchase it online, you can check the description on the details page. If there is no description, you need to purchase carefully or ask customer service.
If you are buying a coat, you need to choose according to your actual situation. For example, in the north, there is heating indoors, so the coat is only worn outdoors, so you don’t need to care about the material of the outer layer of the coat; if you wear the coat every day, you also need to care about the outer material.
Fabrics you can choose: cotton, wool, avoid various man-made fibers .

Friction between clothing and external objects
This situation is common in the friction between pants and seat cushions, clothing and chair backs, and arms and armrests.
In daily life, the surface of many chair cushions is made of mesh material, usually polyester, and the backrest is also made of the same material. In this way, when we sit and move on the chair, or when we get up, the surface of the chair and our clothes will generate a lot of static electricity.
Friction between clothes and skin
Friction between skin and clothes can also generate static electricity? Yes, this is something I didn't expect at all.
But this is a real situation, and the static electricity generated is very high. The drier the skin, the easier it is to generate static electricity.
Chapter 2 Preventing Electricity
If static electricity has been generated and accumulated in the body, how can you prevent yourself from being electrocuted? If only we could painlessly discharge the static electricity.
Wall Supporting Method
When there is static electricity on the body, touching the wall with your hands can release all the static electricity on the body. And because the wall has poor conductivity, it will not produce the tip discharge effect, so people will not feel it.
Tip contact method
is what people often call the key discharge method. The method is very simple: before touching the metal, hold the key with the whole palm and touch the metal with its tip. After the tip is discharged, you will not be electrocuted when you open the lock.
In addition to keys, there is also a product called a static elimination stick. The principle is the same as key discharge. However, this product has one or two diodes inside, which can effectively consume static electricity. It can also intuitively reflect the size of static electricity. The brighter the diode, the greater the static electricity at that time. And because the diode consumes static electricity, the tip discharge effect is not that strong. When you hold it in your hand and touch the metal, you almost feel nothing.

There are many related products. The author has not tried them personally so I will not elaborate much.
Chapter 3 Avoid generating static electricity
The above methods only treat the symptoms but not the root cause. Is there any way to prevent the body from generating static electricity, or the static electricity generated is not enough to make people feel the sting? You must read the methods mentioned below carefully one by one to make sure that you have solved them all, then the static electricity problem will naturally disappear.
1. Maintain the ambient humidity
In the winter in Beijing, the indoor air humidity is generally around 20%. It can be said to be very dry. When I first came to Beijing, I was completely unaccustomed to it and even had nosebleeds. Later I bought an ultrasonic humidifier and left it on for a long time to ensure that the indoor humidity is above 50%. There are several things to note about the
humidifier. First, it is best to use drinking water. Many communities now have convenient water stations, which filter tap water and meet drinking water standards. It is very affordable. It is 3 yuan for 10 liters in Beijing. The humidifier is turned on 12 hours a day. It does not cost 20 yuan a month. It is clean and hygienic.
Second, the humidity of the thermometers and hygrometers I usually buy are not very accurate. I bought three thermometers and hygrometers of a certain meter of the same model and put them together. One showed 20%, one showed 30%, and one showed 40%. I was confused. It is best to use the humidity when you no longer produce static electricity that can shock people. Don't blindly think that everything is safe when the humidity exceeds 50%.
2. Replace clothing containing chemical fiber materials
First of all, the underwear should be replaced with pure cotton, such as thermal underwear and cotton pants that are in direct contact with the skin.
All other clothing must also be checked, because there will be friction between each piece of clothing, which may generate static electricity. Especially if you wear a chemical fiber sweater under the coat, it is a disaster. Both sides will rub and generate double the static electricity.
3. Solve the problem of chair friction
If the surface material of your chair is made of chemical fiber, either change the chair or find a way to solve it.
According to my experience, one way is to put a layer of mat on the seat cushion that is not easy to generate static electricity, such as wool mat, or bamboo mat . If it is not easy to add a cushion to the chair back, you can consider adding a lumbar support so that the clothes will not rub against the chair back, and it can also solve the problem of static electricity between the clothes and the chair.
4. Solve the problem of dry skin (vital)
This problem is a top priority. Why do I say this? Because I have been electrocuted for more than ten years. If I hadn't solved the problem of dry skin by accident, I wouldn't have known that this happened.
Many years ago, I had solved the above three problems, but I still got electrocuted all year round. I thought it was a problem with my physical condition, so I gave up long ago and carried a discharge keychain with me every day.
The solution to dry skin is very simple. Apply body lotion in large quantities and over a wide area. My suggestion is to apply body lotion on any part that your hands can reach. When you first try it, you should not only apply it after bathing, but also apply it on your whole body before going out every day. The standard I set for myself is: no flakes will appear on any part of the body at any time. This can completely eliminate the variable of dry skin and determine whether you have static electricity caused by dry skin.
The body lotion I use is Xiehe Vitamin E lotion, which is very refreshing, so you can safely apply more. It will be absorbed in a while and will not be sticky. Another reason is that it is cheap, and the amount for one winter only costs about 200 yuan.
5. Prevent dry skin problem
This problem varies from person to person. I just want to share my personal experience.
I am from the south, and my skin has always been very dry since I came to the north. Even in summer, dandruff may appear in certain parts of the body. However, I have many colleagues in the north who don’t have dry skin in winter even if they don’t use body lotion. I find it amazing.
After my careful observation and consultation, I found my own reason, which was caused by my bathing habits. I bathe slowly and like to rub mud very frequently. Even in winter, I will take a bath every other day. Some of my colleagues in the northwest may only take a bath once a week in winter and once a day in spring and autumn, but I only take a bath once a day in spring, summer and autumn.
There is no way to change the frequency of bathing. After all, it has been so many years. What can be changed is the bathing habit. From rubbing mud every time you bathe to once a month, you can even skip it all the time. Rubbing mud is very harmful to the skin and can be said to be the main culprit of dry skin.
At this time, some people may be thinking, every time I take a shower, there will be mud when I rub it lightly. There is nothing I can do if I don't rub it. This happens to me too, and the solution is very simple: speed. When rubbing mud becomes a habit, the skin will soften and form mud after a certain period of time when taking a bath. If you can rinse the bubbles very neatly and end the bath, there will naturally be no mud, and you can't even rub it out even if you want to.
Be sure to apply body lotion after taking a shower!
solves the above 4 problems, and the static electricity problem is basically solved. However, it should be noted that it does not mean that you will not generate static electricity, and the static electricity generated will not affect your life. You will not be charged when touching metal.
