1, "discharge" in front of the entrance and exit. Before touching the iron gate, you can put your palm on the wall or the ground to eliminate static electricity, or you can hold a bunch of keys with your hand first, and then touch the iron gate with the tip of the key, so that the electricity on your body will be discharged.

2. Touch the metal door in advance when getting off. When you get off the bus, you can touch the metal door frame in advance to eliminate static electricity, so as to avoid discharging when you suddenly touch the iron door after getting off the bus.

3. Increase the contact area and reduce the pain caused by static electricity. For people who are particularly prone to static electricity, they can touch metal objects with the whole palm, arm and even body, and the charges will be evenly distributed on the surface that is not sharp, resulting in a smaller electric field and a much smaller current density, and it is not easy to feel pain.

4. Try to choose pure cotton products. Choose pure cotton fabrics for clothes and home accessories, and 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.

5, increase the humidity, so that local static electricity is easy to release. Wash your hands and face immediately after using electrical appliances, so that the electrostatic charge on the skin surface can be released in water. Try to choose high moisturizing cosmetics in winter and use humidifiers indoors.

Extended data:

It is very cold in winter, so most people wear cotton-padded jacket to keep warm when they go out. However, in winter, people will encounter static electricity when they touch clothes. This is because the weather is dry in winter and the clothes are cotton. When we are active, the skin and clothes will rub against each other, causing the atoms on the clothes to lose electrons, and the clothes will be in a state of unbalanced charge.

So touching clothes in winter will give you an electric shock. In this case, we can put an old battery in our pocket. When the clothes have static electricity, you can wipe the clothes with the battery negative electrode to eliminate the static electricity on the clothes.
