孕妇的新陈代谢十分旺盛,皮肤散发的热量也增加,在炎热的夏季出汗很多,因此常常借助电风扇纳凉。如果孕妇用电风扇久吹不停,就会有头晕头痛、疲乏无力、饮食下降等不适反应出现。因为电扇的风吹到皮肤上时,汗液蒸发作用会使皮肤温度骤然下降,导致表皮毛细血管收缩,血管的外周阻力增加,而使血压升高,表皮血管呈舒张状态,血流量增多,尤其是头部因皮肤血管丰富,充血明显,对冷的刺激敏感,所以易引起头晕、头痛症状。为了调节全身体温,达到均衡状态,全身的神经系统和各器官组织必须加紧工作,因此,吹风时间长,人并不感到轻松,反而容易疲劳。

孕妇出汗多时,更不要马上吹电风扇,因为这时全身皮肤毛孔疏松,汗腺大开,邪风极易乘虚而入,轻者伤风感冒,重者高热不退,给孕妇和胎儿的健康造成危害。因此,孕妇应注意避免突然或长时间吹电风扇,更不可用吹电扇的方法落汗。必须吹电风扇时,只宜选用微风间隙吹。
