Wrong mode 1: blowing the fixed wind
Now it's mostly a moving head fan. When blowing, the electric fan constantly moves in the position and direction. The blowing will form a big one and a small one, which makes the body surface slowly affected by the wind. It won't make people feel too cold and feel the whole body temperature is even. Therefore, it's better to use the head fan instead of the directional wind.
Wrong way 2: sleeping and blowing
That is to use electric fan to cool down and sleep together. When people are sleeping, the function of the organs of the body is reduced to the lowest level, all the reflexes are disappeared, the immunity is reduced, and diseases are easily caused.
Wrong way 3: long term blowing
Many people like to blow electric fans for a long time. They feel that when they just cool down, they will stop. They will feel that they are still hot. It's not as comfortable as blowing them for a long time.
However, for a long time to the electric fan, the human body temperature will decrease with the evaporation of sweat, which is easy to cause cold, cold, abdominal pain, diarrhea and other diseases. Generally, it is better to blow for half an hour to one hour at a time.
Wrong mode 4: high speed blowing
In order to cool down as soon as possible, some people turn on the electric fan to the highest speed and think that the wind is too strong to relieve the fever, which is not appropriate.
Wrong way 5: blowing near the wind
The electric fan should not be placed near the body. If a strong wind blows near the body and only blows on one side of the body, the sweat on the skin of the winded side will evaporate quickly and the temperature will be significantly reduced. If the wind does not blow on the other side, the sweat will evaporate slowly, resulting in a large gap between blood circulation and sweat discharge on both sides of the body, and the nerve center will lose balance. Once the time is too long, the organs will be tired Can't bear it, so I feel sick all over.
