吹电风扇的伤身误区:
The misunderstandings of the body of the blows:
1、长久吹
1, long blowing
很多人喜欢长时间吹电风扇,觉得刚刚吹凉了身体就停止,会觉得身上还热,不如长时间吹着舒服。可是,长时间对着电风扇吹,人体温度会随着汗液的大量蒸发而下降,容易引起伤风、感冒、腹痛、腹泻等疾病。一般以一次吹风半小时到1小时为宜。
Many people like to blow the fan for a long time. They feel that they stop when the fan has cooled. They feel that they are still hot, so it is better to blow comfortably for a long time. However, a long time facing the electric fan, the body temperature will drop with a large amount of sweat evaporation, easy to cause colds, colds, abdominal pain, diarrhea and other diseases. It is generally appropriate to blow a half an hour to 1 hours.
2、快速吹
2. Fast blowing
有人为了尽快凉爽起来,便把电风扇开到最快速,认为风大过瘾解热。这是不当的做法。当气温超过30℃时,空气温度已接近于人的正常体温,电风扇吹来的风,也是高温风,此时人体的热量主要应靠汗液蒸发散热,如果电扇风吹得过大,皮肤表面温度下降,毛孔闭塞,身体内部汗液散发不出来,还会感到炎热,同时还会出现疲乏无力、腰酸背痛,这就是"憋汗"。因此,不宜用电风扇高档高速吹风,应当调到中速或低速,吹温柔的阵阵微风为好。
Some people in order to cool up as soon as possible, then the electric fan to the fastest, think that the wind is too addictive antipyretic. This is an improper practice. When the temperature is over 30 C, the air temperature is close to the normal body temperature. The wind blowing by the electric fan is also the high temperature wind. At this time the heat of the body should be evaporated by the sweat. If the electric fan is too large, the surface temperature of the skin falls, the pores are blocked, the sweat is not out of the body, and it will feel hot. Sometimes there will be fatigue, lumbago and back pain, which is "sweating". Therefore, it is not suitable to use electric fans high-grade high-speed blowing, should be adjusted to medium or low speed, blowing gentle gusts of breeze is better.
3、吹近风
3. Blow the wind
电风扇吹风不宜放在离身体很近的地方,如果近处吹强风,且只吹身体的一面,使受风面的皮肤汗液蒸发快,温度显著降低,而吹不着风的一面,汗液蒸发慢,致使身体两面的血液循环和汗液排泄差距过大,神经中枢就会失去平衡,一旦时间过久,各器官就会疲惫不堪,从而感到全身不适。因此,在吹电风扇时,尽量与人的距离在2米以外,使吹的风均匀柔和。
The fan blower should not be placed near the body. If a strong wind is blown near the body and only one side of the body is blown, the perspiration of the skin of the wind surface is evaporated quickly, the temperature is significantly reduced, but the wind does not blow and the sweat evaporates slowly, causing the blood circulation of the two sides of the body and the disparities of the sweat drain too large and the nerve center will lose. Balance, once the time is too long, all organs will be exhausted and feel uncomfortable. Therefore, when blowing the fan, try to distance the person from 2 meters away, so that the wind is uniform and soft.
