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。

Japan's overworked businessmen will soon be able to catch up on some sleep in the office – following the invention of a tie that doubles as（兼饰两角） a pillow.

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 vent² discretely³（分离地） located at the back of the neck, which when blown into inflates⁴ it like a pillow.

The tie is made from silk and special micro fibres, which will help to cool skin during the stifling⁵（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 corporate⁶ 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 sartorial⁷（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） .
