湿疹和热痱子的区别

发布日期:2022-05-12 13:59:30编辑:森林

生活中,湿疹和痱子是较为常见的两种皮肤症状,因此湿疹的原因有很多,例如环境因素、饮食因素、身体内在因素等都有可能导致湿疹,而痱子大多由外部因素导致,一般多见于热天或是闷热环境下,因此也称热痱子。很多朋友不知道湿疹和热痱子的区别有哪些,下面小编就来给大家详细讲讲这个问题,一起来了解下吧。
湿疹和热痱子的区别
1、原因不同
引起痱子的大部分原因是外在因素,痱子是因为天气又湿又热,导致汗液不容易排除,滞留在汗腺,把汗腺顶端的皮肤角质层细胞泡肿了,从而把汗腺出口就堵住了。这样汗液更出不去了,只能向周围组织渗透,进入表皮和真皮,形成凸起的小水泡这就是痱子了。而引起湿疹常见有:进食一些如鱼、虾、蛋、牛、羊肉等;吸入某种花粉,如尘螨、羊毛等;病灶感染如扁桃体炎等;生活环境中的日光、炎热、干燥等;化学物质如化妆品、肥皂等;消化不良、胃功能失调、新产代谢失常等。可以看出,痱子是暂时性疾病,湿疹是慢性病程。
 
2、发生时节不同
在季节性方面,痱子和湿疹便有明显的区别,湿疹是不分季节的,一年四季都可能发生,而痱子则是在闷热的环境下才容易发生,所以夏季的高温、高湿决定了痱子的高发程度,另外痱子多见于儿童,成人较少发生。
3、发生部位不同
痱子多出现在颈、胸背、肘窝、腘窝等部位,小孩可发生在头部、前额等多汗部位。湿疹可发生于任何部位,多发生在面颊部、前额、眉弓、耳后等部位。
 
4、症状不同
由于痱子和湿疹发生的原因不一样,所以它们的形态也有很大区别。首先痱子初起时皮肤发红,然后出现针头大小的红色丘疹或丘疱疹,密集成片,但颗颗分明不会融合,其中有些丘疹呈脓性。而湿疹起初为鲜红色,略带水肿,边界清楚,表面湿润,继而转成皮肤一片一片的出现红斑、米粒样丘疹、疱疹、糜烂、渗液和结痂,炎症反应明显,局部皮肤有灼热感和痒感。
 
5、出症程度不同
湿疹一般都是几颗几颗较缓慢地冒出来,不会猛然一下子冒出来一大片。临床上分急性湿疹,亚急性湿疹,慢性湿疹。病程较长,一般2~3周可恢复,慢性者可数月乃至数年而不愈,较易复发。这也是其本质性的区别之一。而痱子就恰好相反,常常突然出现并迅速增多,消退后会轻度脱屑。临床上分为红痱,白痱,在天气转凉即很快消退,但遇热后可复发,延误病期。
湿疹和热痱子怎么护理
痱子怎么护理
1、 开空调风扇:有些家长非常担心小孩子感冒,夏天也不敢开空调。实际上空调保持在26-28度,并且每天多次开窗通风,就既保证了室内的空气清新,并降低了室内温度。
 
2、注意户外活动时间
 
室外活动要避开特别炎热的中午,清晨和黄昏出去玩耍。
 
3、衣物选择:孩子穿纯棉衣服,颜色越清淡越好,给宝宝穿之前用清水清洗,尽量不穿化纤衣物,少用毛织物。孩子衣服要宽松,适当薄一些。保证衣服透气又吸汗。
 
4、经常剪发,保持凉快:孩子的头部是汗腺分布密集的地方,头发不容易散热,最容易长痱子。
湿疹怎么护理
1、湿疹期间忌辛、辣、酒类食物,对鱼、虾等一般易诱发本病的食物应注意停止食用。宝宝如果是母乳喂养的话,就需要注意妈妈的饮食,一些易过敏的食物就要控制。
 
2、有过敏性疾病家族史的父母,其孩子患过敏性疾病的几率也较高。如果婴儿出现湿疹、持续腹泻等过敏症状,父母必须考虑食物过敏的可能。一旦被确诊,可在医生指导下服用无致敏源蛋白的特殊配方奶粉。
 
3、湿疹宝宝大多是易过敏体质,建议做过敏原检测。这样可以找到引起宝宝过敏的源头。
 
4、湿疹的孩子都存着不同程度的皮肤屏障功能受损,要每天坚持不懈地给宝宝涂上安全的皮肤保湿剂,一定要把保湿润肤作为宝宝皮肤护理的头等大事。
