日本一家公司近日研制出一种防疲劳的“睡眠领带”，领带乍看上去和普通的领带没什么不同，但是对着领带背面的充气口吹气，领带就会变身枕头，让白领可以在办公桌旁轻松打盹，以缓解疲劳。
An advert with helpful instructions for the tie.
The new "Nemuri Tie" – which translates as Sleep Tie in Japanese – is a unique inflatable device enabling tired office workers to nap in comfort and style on their desks.
It is disguised as an ordinary tie but contains a hidden air vent discretely（分离地） located at the back of the neck, which when blown into inflates it like a pillow.
The tie is made from silk and special micro fibres, which will help to cool skin during the stifling（令人窒息的） summer humidity, according to the Asahi newspaper.
The Sleep Tie, which was invented by KTM Co, is targeting office workers who are keen for a quick nap on their desk and is currently on sale for around just under £20 (2,500 yen).
Japan is famously home to a corporate culture of long working hours and one of the few places in the world where a word was created to mean "death from overwork" – karoshi.
The Sleep Tie is the latest in a string of sartorial（裁缝的） inventions specifically designed to make the life of a Japanese worker a little more comfortable, particularly during the summer months.
Other unique creations include the Sweat Suit, which appears like a conventional suit but contains unique fibres infused with silver ions which neutralise body odours（气味，声誉） .
