Device Access On-off
In the hot summer, the fan is turned on, the breeze is dry, and it is not pleasant. There are many people who can get sick because of improper use of electric fans. The reason is because many people lack the common sense of using electric fans.
Electric fans are the main heatstroke prevention appliances for many people in summer. However, some people use electric fan methods improperly, which brings harm to health, such as cold, facial nerve paralysis, frozen shoulder, back pain and other symptoms.
Five injury misunderstandings of blowing electric fans:
1, long blowing
Many people like to blow the electric fan for a long time. If they feel that they have just cooled down, they will stop. They will feel that the body is still hot. It is better to blow comfortably for a long time. However, when the electric fan is blown for a long time, the body temperature will drop with the evaporation of sweat, which may cause diseases such as colds, colds, abdominal pain, and diarrhea. Generally, it is preferred to blow air for half an hour to one hour.
2, fast blowing
In order to cool up as soon as possible, someone opened the electric fan to the fastest, and thought that the wind was great and hot. This is an inappropriate practice. When the temperature exceeds 30 °C, the air temperature is close to the normal body temperature of the person, and the wind blown by the electric fan is also the high temperature wind. At this time, the heat of the human body should mainly be evaporated by the sweat, if the wind blows too much, the skin surface The temperature drops, the pores are occluded, the sweat inside the body does not emanate, and it will feel hot, and there will be fatigue, backache and back pain. This is “sweat”. Therefore, it is not advisable to use a high-speed high-speed air blower for electric fans. It should be adjusted to medium or low speed, and it is better to blow a gentle breeze.
3, blowing close to the wind
The air blower should not be placed close to the body. If the wind blows in the vicinity and only blows the side of the body, the sweat on the wind surface will evaporate quickly, the temperature will decrease significantly, and the side that blows the wind will not evaporate slowly. As a result, the blood circulation and sweat excretion on both sides of the body are too large, and the nerve center will lose its balance. Once the time is too long, the organs will be exhausted and feel uncomfortable. Therefore, when blowing the electric fan, it is preferable to make the distance between the person and the person 2 meters, and the blowing wind is evenly softened.
4, blowing directional wind
The electric fan is mostly a moving head fan. When the air blows, the electric fan keeps moving the position and direction. The air blows to form a large and small one, which makes the body surface suffer from the wind slowly, does not make people feel too cold, and feels the whole body temperature is even. Therefore, it is best to use a fan, not to blow the directional wind.
5, falling asleep
That is to use an electric fan to cool down with sleep. When the person is asleep, the functions of the organs of the body are reduced to the lowest level, all the reflections disappear, the immunity is reduced, and the disease is easily caused.
