A glowing spark while shaking hands with someone, getting into a car, opening a door, reaching for a metal pen, and the “static electric shock” that occurs suddenly with a slight but frightening pain in the hand, has been making itself felt more and more lately. So why?
Humanity meets electricity static thanks to it. The discovery that amber material, called ebonite rod, when rubbed against certain objects, attracts small objects, dates back to BC. Direct current and alternating current were discovered much later than static electricity, in the 18th and 19th centuries.
Although everyone experiences static electricity shock, which has been a part of our lives since the early ages, from time to time. recently The number of people complaining about this has increased considerably. There are various reasons for this situation.
Static electric charge to the human body occurs due to friction and the environment.
Many of the objects we wear polyester and nylon made of synthetic materials such as Moreover, we wear shoes that outweigh the plastic aspect. When these come into contact with the body in any way, they cause the body to be negatively charged. plastic shoes Because we wear it, we cannot transfer it to the ground. The layers of clothing we wear in winter increase this effect even more.
In addition, we work together with computers and smart phones in office environments with a high electrical load.
As a result, when our body, which is loaded with ions, comes face to face with a neutral or electrically charged object, such as a door handle, car door, or even another person, “spark” It discharges all the load with a spark jump. This causes an unpleasant sensation similar to an electric shock.
This happens more in dry weather conditions (usually in winter).
Because the air is dry insulator feature and allows load accumulation. The humidity in the environment directly affects the tension created. That’s why you work, live It is important that you moisturize the environment.

The positive charge is higher in closed areas, and the negative charge is higher in open areas, forested areas and in the natural environment. Therefore go out into the natural environment It also helps to remove static electricity. In addition, in vehicles such as air conditioners, devices that emit negative ions can be preferred. Stepping on the ground with bare feet is also a good method.
Although static electric shock can reach up to 8-10 thousand volts in places, it does not pose a serious danger.
However, especially with flammable, explosive and flammable materials and people working with sensitive electronic devices need to be extremely careful. For example, in the event of such a situation among the employees working at fuel stations, great disasters may be caused as a result of the flashing or explosion of the fuel oil. Also, sensitive electronic devices can break down. For this reason, a carbon bracelet or wristband, for example, should be used in a way that those working in these areas can discharge static electricity. with shoes that can conduct electricity to the ground their work is very accurate.
It has been observed that people who play sports on carpet pitches exhibit a much more stressful and fight-prone structure than those who do sports on open and soil pitches.
Electrostatic charge generation voltage levels
In a study on this, it was found that there is a serious static electricity charge on the people who do sports and this causes affects the nervous system detected.
In order to personally avoid this situation, synthetic clothing should be avoided as much as possible.
Conductive materials in shoes and natural materials in clothes, for example cotton and linen products We should choose. In addition, the environment must be humidified.
