Precautions

In the hot summer, when the electric fan is turned on and the breeze blows, it is very uncomfortable. Many people get sick due to improper use of the electric fan. The reason is that many people lack the common sense of using the electric fan.

The electric fan is the main heatstroke prevention and cooling appliance for many people in summer. However, some people use electric fans improperly, which brings harm to health, such as colds, facial paralysis, frozen shoulder, backache and other symptoms.

 

blowing electric fan of five errors of injury:

1, long blow

Many people like to blow electric fans for a long time. They feel that they will stop just after blowing cold. They will feel that their bodies are still hot, which is not as comfortable as blowing for a long time. However, blowing on the electric fan for a long time, the body temperature will drop with the evaporation of sweat, which can easily cause colds, colds, abdominal pain, diarrhea and other diseases. Generally, it is appropriate to blow air for half an hour to 1 hour at a time.

2, fast blowing

In order to cool down as soon as possible, some people turned on the electric fan as fast as possible, thinking that the wind was strong enough to relieve fever. This is improper practice. When the temperature exceeds 30 ℃, the air temperature is close to the normal body temperature of human beings. 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 dissipated by sweat evaporation. If the electric fan wind is blown too much, the skin surface temperature will drop, the pores will be blocked, the sweat inside the body will not be emitted, and the body will feel hot. At the same time, there will be fatigue and backache ". Therefore, it is not appropriate to use the high-grade high-speed blowing fan, should be transferred to the medium speed or low speed, blowing gentle breeze as well.

3. Close wind

The electric fan should not be placed very close to the body. If strong wind is blown near and only one side of the body is blown, the skin sweat on the wind-affected surface will evaporate quickly and the temperature will be significantly reduced, while the skin sweat on the wind-affected side will evaporate slowly, resulting in too large a gap between blood circulation and sweat excretion on both sides of the body, and the nerve center will lose balance. Once the time is too long, all organs will be exhausted and the body will feel uncomfortable. Therefore, when blowing the electric fan, it is best to be 2 meters away from the person, so that the wind is even and soft.

4. Blow directional wind

Most of the electric fans are shaking their heads. When blowing, the electric fans move their positions and directions continuously. The blowing forms a burst of large and small, which makes the body surface slowly affected by the wind, does not make people feel too cold, and feels the whole body temperature is even. Therefore, it is best to use a shaking head fan instead of blowing directional wind.

5, fall asleep.

That is, an electric fan is used to cool down and sleep. When people are asleep, the functions of various organs of the body are reduced to the lowest level, all reflexes disappear, immunity decreases, and it is easy to cause diseases.
