你有多久沒(méi)睡“美容覺(jué)”了？瑞典一項(xiàng)研究顯示，“美容覺(jué)”的確有作用，睡得好確實(shí)能讓人看上去更有吸引力，睡不好則會(huì)讓你的形象減分。

Beauty sleep is a real thing, according to researchers who have shown that people who miss out on sleep do appear less attractive to others.
“美容覺(jué)”確有其事。研究人員表示，比起睡得好的人，睡眠不足的人顯得沒(méi)有那么光彩照人。

A couple of bad nights is enough to make a person look "significantly" more ugly, their sleep experiments suggest.
研究人員開(kāi)展的睡眠實(shí)驗(yàn)結(jié)果顯示，幾個(gè)晚上睡得不好便足以讓一個(gè)人看起來(lái)“特別地”不好看。

Dark-circled "panda" eyes and puffy lids can even put others off socialising with you, they say.
研究人員稱，黑眼圈和腫腫的眼皮甚至可能會(huì)讓身邊的人遠(yuǎn)離你。

People were rated by strangers as less healthy and approachable when they had tired faces.
當(dāng)人們表現(xiàn)出疲憊相時(shí)，素不相識(shí)的人會(huì)認(rèn)為他們的身體狀況不佳且不是很好接近。

The researchers asked 25 university students, some male and some female, to be the guinea pigs in their sleep experiment.
研究人員請(qǐng)25名大學(xué)生參與了睡眠實(shí)驗(yàn)，其中有男有女。

The volunteers - who were given payment for their help - were sent home with a kit that would measure their night-time movements to check that they had not cheated and slept when they should not have.
志愿者在參與實(shí)驗(yàn)后可以得到一定的報(bào)酬。研究人員向他們各自發(fā)放了一套工具，讓他們帶回家。這套工具會(huì)通過(guò)測(cè)量他們夜間的活動(dòng)，以驗(yàn)證他們沒(méi)有說(shuō)謊，在原本不會(huì)睡覺(jué)的時(shí)候進(jìn)入睡眠狀態(tài)。

They were asked to get a good night's sleep for two consecutive nights.
志愿者被要求連續(xù)兩個(gè)晚上保持良好的睡眠狀態(tài)。

A week later, they were asked to restrict themselves to only four hours sleep per night for two nights in a row.
一個(gè)星期后，他們被要求將他們的睡眠時(shí)間壓縮到連續(xù)兩天每天僅睡四個(gè)小時(shí)。

The researchers took make-up free photos of the volunteers after both the good and the bad sleep sessions.
在志愿者進(jìn)行了好的睡眠和差的睡眠之后，研究人員分別拍攝了志愿者們的素顏照片。

Next, they asked 122 strangers - women and men living in Sweden's capital city, Stockholm - to have a look at the photos and rate them on attractiveness, health, sleepiness and trustworthiness, as well as asking them: "How much would you like to socialise with this person in the picture?"
接著，研究人員召集了122名與志愿者素不相識(shí)的陌生人。他們當(dāng)中有男有女，都住在瑞典首都斯德哥爾摩。這些人被要求看著志愿者的照片，對(duì)他們的魅力程度、健康狀況、睡眠情況和信任程度進(jìn)行評(píng)價(jià)。研究人員還會(huì)問(wèn)他們一個(gè)問(wèn)題：“你有多想跟照片上的這個(gè)人交朋友？”

The strangers were good at judging if the person they were looking at was tired, and, if they were sleepy, their attractiveness score suffered.
這群人的眼力很好。如果照片上的人顯得疲倦不堪，或者看起來(lái)很缺覺(jué)，他們魅力程度的分?jǐn)?shù)便很低。

The strangers also said they would be less willing to socialise with the tired students, who they also perceived to be less healthy, Royal Society Open Science journal reports.
據(jù)英國(guó)期刊《皇家協(xié)會(huì)開(kāi)放科學(xué)》報(bào)道，這些陌生人也表示，他們更不愿意與那些看起來(lái)很累的學(xué)生交朋友，他們認(rèn)為這些人的身體狀況不太好。

The Karolinska Institute researchers says this makes sense in evolutionary terms.
來(lái)自卡羅林斯卡學(xué)院的研究人員說(shuō)，從進(jìn)化的角度來(lái)看，這十分符合常理。

"An unhealthy-looking face, whether due to sleep deprivation or otherwise, might activate disease-avoiding mechanisms in others."
“一張看起來(lái)不健康的臉，不管它是由于睡眠不足還是其他原因?qū)е碌模伎赡軙?huì)激活其他人身體內(nèi)躲避疾病的機(jī)制。”

In other words, people don't want to hang around with people who might be ill, whereas someone who looks energetic and fit will hold lots of appeal.
換句話說(shuō)，人們不想跟可能患病的人待在一起。而那些看起來(lái)活力四射、身體健康的人則魅力十足。

Lead researcher Dr Tina Sundelin added: "I don't want to worry people or make them lose sleep over these findings though.
首席研究員蒂娜?孫德琳博士補(bǔ)充道：“我不希望這些實(shí)驗(yàn)結(jié)果讓人們擔(dān)憂或者睡得不好。”

"Most people can cope just fine if they miss out on a bit of sleep now and again."
“偶爾睡得不好沒(méi)有關(guān)系，大部分人都可以恢復(fù)得很好。”

Dr Gayle Brewer, a psychology expert at the University of Liverpool and member of the British Psychological Association, said: "Judgement of attractiveness is often unconscious, but we all do it, and we are able to pick up on even small cues like whether someone looks tired or unhealthy.
蓋利?布魯爾博士是利物浦大學(xué)的一名心理學(xué)專家及英國(guó)心理學(xué)協(xié)會(huì)成員。他說(shuō)：“對(duì)外表魅力程度的評(píng)價(jià)往往是無(wú)意識(shí)的，但是我們一直都在做這件事。我們能夠從一些很小的細(xì)節(jié)，比如說(shuō)這個(gè)人是否疲憊或者是否健康，來(lái)對(duì)他人進(jìn)行評(píng)價(jià)。”

"We want our partners to be attractive and energetic.
“我們希望我們的伴侶看起來(lái)魅力十足，充滿活力。”

"This study is a good reminder of how important sleep is to us."
“這個(gè)研究對(duì)我們來(lái)說(shuō)是一個(gè)很好的提醒，它告訴我們，睡眠是多么重要。”
