Even as we get older， some of us dont like to sleep in a dark place. Otherscan only get a good sleep when its pitch-dark3. These people can find it difficultto sleep when the sun rises early during the summer.

Viviana Greco， a researcher from Cardiff University， is one of those people.When she moved to Wales from Italy， she found that her curtains4 werentkeeping her room dark， and she was waking up early in the summer. So， as asleep scientist5， she started to study with a team from Europe and the US. Shelooked at how wearing an eye mask at night worked on peoples thinking the nextday. And according to their study， wearing an eye mask at night may help us feelmore alert6， and might even improve our memory.

They did two experiments7. In the first one， 89 people spent a week—insummer—wearing an eye mask at night. After five days， the researchers did sometests to measure8 memory and how alert they were. They then spent a weeksleeping without a mask and did the same tests. The results showed that peoplewere more alert and had better memories after a week of sleep with the mask.Thirty-three people took part in the second experiment. This time they wore asleep tracking9 device10. The device showed that people had better memorieswhen they spent more time in deep sleep wearing a mask.

即使隨著年齡的增長(zhǎng)，我們中的有些人也不喜歡在黑暗的環(huán)境中睡覺(jué)。其他人只有在漆黑的夜里才能好好休息。當(dāng)夏天太陽(yáng)很早就升起的時(shí)候，這些人會(huì)發(fā)現(xiàn)很難入睡。

來(lái)自卡迪夫大學(xué)的研究員維維安娜·格雷科就是其中之一。當(dāng)她從意大利搬到威爾士時(shí)，她發(fā)現(xiàn)窗簾并不能讓她的房間保持黑暗，在夏天她很早就會(huì)醒來(lái)。因此，作為一名睡眠科學(xué)家，她與來(lái)自歐洲和美國(guó)的團(tuán)隊(duì)合作，研究了晚上戴眼罩如何影響人們第二天的思維。根據(jù)他們的研究，晚上戴眼罩可以幫助我們更警醒，甚至可以改善我們的記憶力。

他們做了兩個(gè)實(shí)驗(yàn)。在第一個(gè)實(shí)驗(yàn)中，89 人在夏天晚上戴了一周的眼罩。五天后，研究人員進(jìn)行了一些測(cè)試，以測(cè)量參與者的記憶力和警醒程度。然后，他們?cè)诓淮餮壅值那闆r下睡了一周，并做了同樣的測(cè)試。結(jié)果顯示，戴著眼罩睡了一周后，人們變得更加警醒，記憶力也更好。三十三個(gè)人參加了第二個(gè)實(shí)驗(yàn)。（實(shí)驗(yàn)操作類似）這次他們戴上了睡眠追蹤設(shè)備。

該設(shè)備顯示，當(dāng)人們?cè)诖餮壅值那闆r下用更多的時(shí)間深度睡眠時(shí)，他們的記憶力會(huì)更好。
