Thì phải thay đi chứ

các nhà khoa học nói rằng ngủ mà đi tất thì giống như "nằm trong toilet" :D

If you wear the same socks to bed that you wore during the day, you might want to look away now.

New research has revealed just how dirty our socks can get on a daily basis, and it’ll make people think twice about leaving socks on overnight (qua đêm).

Not everyone wears them to sleep in, of course, but a US study (nghiên cứu) estimated (ước tính) that up to a third of people regularly or occasionally do choose to keep them on in bed.

It turns out they’re dirtier (bẩn thỉu) than you might imagine. The study saw researchers swab pairs of socks that had been worn throughout the day from 7am to 11pm.

They found that in half of the socks samples, Pseudomonas aeruginosa (trực khuẩn mủ xanh) could be detected.

The bacteria can cause a large number of infections, and it’s also commonly found on cockroaches and in their droppings (phân) - not exactly the kind of thing you want to have close to your skin.
