卫生间的门不用时应该开着还是关着？做错了可能会引起感染|卫生间|垃圾桶|房间|换气扇|淋浴|马桶

我们在不用卫生间的时候，卫生间的门应该开着还是关着呢？因为大家的生活习惯不同，所以这个问题一直是大家争论不休的一个话题，就像应该先有鸡还是先有蛋一样。

觉得应该开着门的一方认为，卫生间长时间处于潮湿的环境，应该开着门通风换气，缓解潮湿。

认为应该关着门的一方则觉得卫生间内的细菌太多，而且卫生间的气味也不好闻，关着门可以防止细菌和臭味的扩散。

那么卫生间在不用的时候门究竟应该开着还是关着呢？那么今天小编就为大家具体解析一下。

1、卫生间内环境潮湿，容易滋生细菌

卫生间是我们平时洗手盥洗淋浴的地方，而且我们还会在卫生间内洗衣服，所以卫生间基本全天都会处在潮湿的环境当中，于是卫生间潮湿的环境成为了滋养细菌十分有利的一块“沃土”。

尤其是没有做卫生间干湿分离的家庭，在卫生间淋浴后水蒸气会充斥整个卫生间。若此时开着门，卫生间内的水蒸气就会混合着卫生间内的细菌弥漫到各个房间去。久而久之，还可能会引起其他房间内墙纸的脱落，甚至会损耗家具，墙壁也可能因此而发霉。

2、排泄物内的有毒气体

卫生间内马桶里的排泄物是会产生氨气的，即使顺着马桶冲下去了还是会随着管道返回来一部分。而氨气是有毒的，轻微吸入氨气会导致嗅觉疲劳，接下去就不会感到氨气的刺激性气味。

氨气轻中度中毒者会有鼻炎，咽炎等症状，等氨气进入气管还可能会引起咳嗽、咯痰、痰内有血等症状，严重时可导致呼吸道刺激和灼伤。所以关上卫生间的门可以有效地防止氨气进入其他房间。

3、垃圾桶产生的细菌

为了防止卫生纸直接冲到马桶里会堵塞下水道，我们都会在卫生间内放一个垃圾桶。

扔在垃圾桶里的卫生纸上有人体的排泄物，放置在卫生间不仅会产生臭气还会滋生我们肉眼看不见的细菌。关上卫生间的门可以有效地隔绝卫生间内的臭气和细菌了。

但是如果单纯的关上卫生间的门无异于在家里添加了一个“细菌制造厂”。所以有没有更好的做法呢？

1、如果卫生间有窗户

如果卫生间有窗户，关上卫生间的门打开窗户应该就是最完美的做法了。

这样既可以保证卫生间内的细菌不会蔓延到家里其他地方，又可以缓解卫生间内空气地潮湿，减少细菌的滋生。https://pd.qq.com/s/4qicx9mr4
