Summer is coming, although most people are choosing to hide under the cool air conditioning, but also can not avoid blowing fans. Even blowing fans we should also pay attention to the problem.
Avoid blowing for a long time
Many people like to blow the electric fan for a long time, think just blowing cool the body to stop, will feel the body is still hot, not as comfortable as a long time blowing. However, a long time blowing on the electric fan, the body temperature will drop with the evaporation of sweat in large quantities, easily caused by wind, cold, abdominal pain, diarrhea and other diseases. Generally blowing for half an hour to an hour at a time is appropriate.
Avoid high-speed blowing
Some people in order to cool up as soon as possible, they will turn on the electric fan to the highest speed, that the wind is addictive relief heat. This is an inappropriate practice. When the temperature exceeds 30 ℃, the air temperature is close to the normal body temperature, electric fans blowing wind, but also high-temperature wind, the body's heat should mainly rely on sweat evaporation heat, if the electric fan wind blowing too much, the skin surface temperature drops, pores closed, the body does not emit internal sweat, but also feel the heat, but also fatigue and weakness, back pain, which is "holding sweat". Therefore, it is not advisable to use electric fans high-grade high-speed blowing wind, should be adjusted to medium or low speed, blowing gentle gusts of breeze for good.
Avoid blowing near the wind
Electric fan blowing wind should not be placed very close to the body, if the close blowing strong wind, and only blowing one side of the body, so that the wind side of the skin sweat evaporates quickly, the temperature is significantly lower, and blowing the side of the wind, sweat evaporates slowly, resulting in the blood circulation and sweat excretion gap between the two sides of the body is too large, the nerve center will be out of balance, and once too long, the organs will be exhausted, thus feeling general discomfort. Therefore, when blowing electric fans, the best distance from people in 2 meters away, so that the wind blowing evenly and softly.
Avoid blowing directional wind
Nowadays, the electric fan is mostly a moving head fan, when blowing the wind, the fan constantly moves its position and direction, blowing wind forms a large a small, so that the surface of the body by the wind slowly some, will not make people feel too cool, feel the whole body temperature uniform. Therefore, it is best to use the shaking head fan, do not blow directional wind.
Avoid falling asleep blowing
That is, using electric fans to cool down with sleep. When people are asleep, the function of the organs of the body to the lowest level, all reflexes disappear, immunity is reduced, easy to incur disease.
