穿着外裤，能直接坐床上吗？
双语君约 5 分钟Many people worry about bringing germs home on their clothes, but experts say that the risk of infection through clothing is generally low.
对大多数健康人群
不用过于担心
① 需要足够数量的病原体
大多时候，外衣上存在的极少量病原体并不足以让人生病，一般都要达到一定的数量才能引发感染。
② 病原体存活时间有限
不少导致呼吸道和胃肠道疾病的病原体在体外存活的时间并不长。一项针对新冠病毒的建模研究发现，病毒在棉质衣物上会比较快地失活，甚至，仅乘车通勤后回家，衣物上有传染性的病毒量就可能减少80%之多。
③ 衣物纤维的“吸附”作用
衣物的纤维可以在一定程度上“锁住”病毒和细菌颗粒，让它们不那么容易通过接触转移到人的手上或其他表面。
④ 传播效率远低于直接吸入
主流观点认为，与直接吸入感染者咳嗽或打喷嚏产生的飞沫相比，衣物上附着的病原体“生物利用度”要低得多。同样的，新冠病毒的建模研究发现，由衣物上的悬浮颗粒引起的“二次吸入暴露”情况，要比在工作场所的吸入暴露低2到3个数量级，这几乎是可以忽略不计。
Most pathogens on clothing are unlikely to be present in amounts large enough to cause illness. Many also survive only briefly outside the body, and exposure through clothing is far less significant than direct exposure to respiratory droplets.
外衣的另一个风险
可能携带过敏原
Clothing can, however, carry allergens such as pollen into the home. People with seasonal allergies may benefit from changing clothes after returning home.
① 回家后立即脱掉外衣
② 定期用吸尘器清洁布质家具
③ 由于花粉也会附着在人的皮肤、头发甚至眉毛上，在花粉季外出时可以考虑戴上帽子和太阳镜，且回家后洗头、洗脸。
Experts also stress that good hand hygiene remains one of the most effective ways to prevent disease transmission.
起床不马上叠被子
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
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
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
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.
