Why do you get an electric shock in winter?

Because most people wear clothes made of fibers in winter, fibers will generate static electricity when rubbing against the skin.

When the human body is active, the friction between skin and clothes, and the friction between clothes will generate static electricity. With the increase of household appliances and the increase of people wearing chemical fiber clothes in winter, the electrostatic charges generated by household appliances will be absorbed and accumulated by the human body. In addition, the walls and floors of the room are mostly insulators, and the air is dry, which is more susceptible to static interference.

Because the skin of the elderly is relatively dry than that of the young, and the cardiovascular system of the elderly is aging, the anti-interference ability is weakened, and the elderly are more susceptible to static electricity. In the elderly with various diseases of cardiovascular system, static electricity will aggravate the condition or induce arrhythmia such as ventricular premature beats. Too much static electricity often makes people fidget, headache, chest tightness, dyspnea and cough.

In order to prevent the occurrence of static electricity, it is necessary to maintain a certain humidity indoors, often mop the floor, often sprinkle water, or humidify with a humidifier; Take a bath and change clothes frequently to eliminate the static charge accumulated on the surface of human body. When you find that your hair can't be combed, soak the comb in water for a while, and then comb your hair after the static electricity is eliminated. After taking off your clothes, gently touch the wall with your hands, and touch the wall with your hands before touching the door handle or faucet to "discharge" the static electricity in your body, so as not to hurt you. For the elderly, we should choose soft and smooth cotton or silk underwear and underwear, and try not to wear chemical fiber clothing to minimize the harm of static electricity.

1, wash your hands before going out, or put your hands on the wall to remove static electricity, and try not to wear chemical fiber clothes.

2. In order to avoid electrostatic strike, you can use small metal devices (such as keys) and cotton cloth to touch doors, door handles, faucets, chair backs, bed railings, etc. To eliminate static electricity, and then touch them with your hands.

3. Wear cotton underwear.

4. When you are ready to get off, hold the gear with your right hand, then touch the iron part below with your fingers, then open the door, and put your left hand on the iron part of the door, but don't let go of your left hand, then let go of your right hand and get off. At this time, if you hold the door with your right hand, you will not get an electric shock. . Then push hard and it's done ~ ~

5. To deal with static electricity, we can adopt both "prevention" and "release". "Prevention", we should try to choose pure cotton products as fabrics for clothes and home decoration, and try to avoid using chemical fiber carpets and furniture with plastic as surface materials to prevent friction and electrification. Try to stay away from TV, refrigerator and other electrical appliances to prevent induction electrification. "Discharge" is to increase humidity and make local static electricity easy to release. When you turn off the TV and leave the computer, wash your hands and face immediately, so that the electrostatic charge on the skin surface can be released in the water. Try to choose high moisturizing cosmetics in winter. Commonly used humidifier. Some people like to keep ornamental fish and daffodils indoors, which is also a good way to adjust indoor humidity.

In addition, an economical and practical humidification method is recommended: put a basin of water under the heating, use an old towel (or absorbent cloth), put one end in the water and the other end on the heating, so that about three liters of water can be evaporated into the house day and night. If every heater does this, the whole room will feel damp and pleasant. it wont hurt you to try it

6. Bathing and changing clothes frequently can effectively eliminate the static electricity accumulated on the surface of human body.

Here are two tips to help prevent this kind of electric shock.

1. indoors, static electricity may be generated after the carpet rubs the sole, and the wind outside may make the body charged. Be careful to touch the iron gate when entering and leaving at this time, and your hands may get an electric shock. After repeatedly encountering such a situation, you can take the following measures to avoid electric shock:

When touching the iron gate, don't touch the iron gate directly with your hands. Instead, grab a bunch of keys in your pocket with your hand (usually it won't get an electric shock), and then touch the iron gate with the tip of the key, so that the electricity on your body will be discharged without getting an electric shock.

Principle: The pain of hand discharge is caused by high-voltage discharge. When discharging, the hand suddenly touches the iron gate very little, resulting in instantaneous high voltage. If you take the key out of your pocket, first press the key in a large area (a string of keys itself can't transfer much charge, so it won't get an electric shock at this time), and then use the key tip to touch the big conductor. At this time, the contact point of discharge is not a certain point on the skin of your hand, but the tip of the key, so your hand will not feel pain (maybe the key will! -If it hurts.

2. You often get an electric shock when you get off a taxi. It is mainly the static electricity accumulation caused by the friction between the body and the seat when getting off the bus. When closing the door after getting off the bus, the hand suddenly touches the iron gate and will get an electric shock.

When this often happens, it is best to pay attention to: when you get off the bus, that is, when your body rubs against the seat, you can hold the metal door frame in advance, so that static electricity can be discharged from your body at any time when it is generated by friction, so as to avoid discharging when you suddenly hit the iron gate after getting off the bus.
