近期，“穿外裤不能上床真的有必要吗”的话题冲上热搜，引发一场有关卫生与健康的讨论。



The topic "Is it really necessary to avoid sitting on the bed while wearing outdoor pants?" has sparked widespread discussion among netizens regarding hygiene and health practices.

网友们各执己见，评论区直接炸开了锅！






以上评论不无道理，因为新闻中经常报道一些人在公共场合的不文明行为。

还有电影院座位虫卵事件的曝光让人心惊胆战。



而另一方网友认为：人本身是具有一定免疫力的，而且细菌无处不在，没必要那么讲究！






Some netizens argue that caution is warranted, citing frequent reports of uncivilized public behavior that could spread germs. Others, however, contend that the human body naturally possesses immunity and that bacteria are omnipresent — making excessive fastidiousness unnecessary.

其实经过公共环境“洗礼”的外裤，或多或少都会沾染各种细菌、病毒、灰尘等。许多公共用具看似干净、无害，实际上潜藏着很多健康隐患。所以，在公共场合戴口罩，携带消毒湿巾及时擦拭，及时洗净双手等也是被提倡的。



但是，日常不可能打造出无菌环境。人民网也曾科普：过度追求无菌环境会大大减少人体接触病原体的机会，导致免疫系统缺乏必要的刺激，最终可能增加过敏性疾病的发生风险。

至于“穿外裤能否上床”，其实更多与个人或家庭卫生习惯有关。在日常生活中，无论是否认同这一热搜话题，都要尊重身边人的卫生习惯。

As for whether one should avoid sitting on the bed in outdoor pants, this ultimately comes down to personal or household hygiene preferences. In daily life, regardless of one's stance on this viral topic, it is important to respect the hygiene habits of those around us.

保持健康正确的卫生习惯可以减少生病、感染等风险。那么，日常生活中，哪些是常见的卫生习惯误区呢？下面是来自人民网科普和科普中国的几点建议，一起来看看吧！

起床不马上叠被子

研究表明，人在每晚睡觉时流失的液体最多可达1升。如果起床立刻叠被子，和人体接触的那面就会被层层压在最里面，而积累了一晚的温度和湿度，可能就成了螨虫的培养皿。

起床后，可以直接将被子与身体接触的一面翻过来，晾一晾，让水分蒸发出去。

After waking up, you can turn the side of the duvet that has been in contact with your body outwards to air it out, allowing the moisture to evaporate.



上厕所不中途冲水

冲水时，大量混合着粪便的微小液滴，会以每秒2米的初始速度喷射出来。如果马桶盖子没有盖上，这些微小液滴会被喷到马桶上方1.5米的高度。

在上厕所中途冲水时最好先起身，盖上马桶盖再冲水，既可以确保脏东西不会喷溅到马桶以外，又可以避免身体接触到可能含有致病细菌、病毒的气溶胶。

First rise from the seated position and securely close the toilet lid before flushing. This dual-action safeguard simultaneously prevents particulate splatter beyond the basin and shields you from potentially pathogenic bioaerosols.

用完洗衣机不关门

刚洗完衣服的洗衣机内部，是比较潮湿的环境，非常有利于微生物（特别是霉菌）的繁殖。这会污染下一次洗的衣物。

最简单有效的方法，就是洗完衣服保持洗衣机的盖子打开的状态，让内部自然风干。

The simplest and most effective method is to leave the washing machine lid open after the clothes are done washing, allowing the interior to air dry naturally.



卸完妆不再用洗面奶

很多人觉得，卸妆后再拿洗面奶洗脸才会干净。但其实，两次清洁对皮肤角质层来说，已经超负荷了。所以，卸完妆后不用洗面奶洗脸的人，皮肤屏障会感谢你的！

洁面时感觉到的摩擦力，其实是皂基与水中的钙镁离子发生反应，结合生成“皂垢”导致的，和皮肤的清洁程度并没有关联。要是长期过度清洁，皂垢不断在皮肤上堆积，就会损伤皮肤屏障，大大增加变成敏感肌的风险。

The friction felt during cleansing is actually caused by the reaction of soap base with calcium and magnesium ions in water, which combine to form "soap scum". This has nothing to do with the degree of skin cleanliness. If you over-cleanse for a long time and soap scum keeps building up on the skin, it will damage the skin barrier and greatly increase the risk of becoming sensitive-skinned.
