Static electricity is an electric charge in a static state, and the friction of dry objects can generate static electricity. The electromagnetic field generated by electrostatic discharge is very strong. This strong electromagnetic field has a short action time but its intensity is much stronger than the electromagnetic field radiated by a mobile phone, and the number of discharges is very large, and its effect on the human body cannot be ignored. If the human body is exposed to high electrostatic radiation for a long time, symptoms such as restlessness, headache, chest tightness, difficulty breathing, and cough will occur.
In the dry season, if you wear chemical fiber clothes and insulated shoes to walk on the insulated ground and other activities, the static electricity on the human body can reach thousands of volts or even tens of thousands of volts. According to the test, there is a sensation in the fingers; sparks appear when the voltage exceeds 3000 volts, and the fingers feel pain like needles; when the voltage exceeds 7000 volts, people feel an electric shock. Studies by medical experts have confirmed that skin electrostatic interference can change the normal potential difference of the human body surface and affect the normal electrophysiological process of the myocardium. This kind of static electricity can aggravate the patient's condition, and long-lasting static electricity can also increase the alkalinity of the blood, leading to itching and pigmentation of the skin, affecting the physiological balance of the human body, and disturbing the mood of the person. Therefore, the incidence of facial diseases such as facial erythema and hyperpigmentation of office workers who operate computers every day is much higher than that of those who do not use computers. This is caused by the static electricity generated by the computer screen attracting a large amount of suspended dust and irritating the face.
