睡得好才能精神好：睡覺的12個有趣事實

The National Sleep Foundation (NSF), an independent nonprofit organization, conducted an international poll to compare the sleeping habits of people in six different countries. 獨立的非盈利組織國際睡眠機構（NSF）在全球範圍內做了一個問卷調查，來比較六個不同國家人們的睡眠習慣。

The NSF polled individuals in the United States, Canada, Germany, Japan, Mexico, and the United Kingdom between the ages of 25 and 55 about their sleep habits. The study wasn't peer reviewed or published in a journal, but here are some interesting facts they found: 該項調查所涉及的國家有：美國、加拿大、德國，日本、墨西哥以及英國，調查人羣在25-55歲之間，重點調查他們的睡眠習慣。該項調查並沒有正式在期刊上發表，下面是他們發現的一些有趣的事實：

2. The United States and Japan are getting the least amount of sleep overall. 美國和日本的平均睡眠時間最少。

Consequently, about one-half from both countries reported at least one nap in the last two weeks. 所以，這兩個國家大概只有一半的人表示在過去半個月內午休過至少一次。

3. About a quarter of respondents in the United States, the United Kingdom, and Canada never or rarely sleep well before a workday. 工作日前一晚，美國、英國和加拿大四分之一的被調查者表示無法安睡。

The United States and Japan led the way for those who get less than six hours of sleep before a workday, and about two-thirds in Japan and half in the United States sleep less than seven hours before work. 美國和日本大部分的調查者工作日前一晚的睡眠時間不到六小時，其中三分之二的日本人和一半的美國人睡眠時間不到七小時。

4. In the United Kingdom almost one-third sleep naked. 三分之一的英國調查者喜歡裸睡。

While over half of the respondents in all six countries reported sleeping in pajamas, the United Kingdom seems to be a little more liberal. 雖然這六個國家的調查者中半數以上的人都聲稱會穿睡衣睡覺，然而英國似乎要更開明一點。

5. Pillows are most important to the United States. 對於美國人而言，枕頭必不可少。

The United States reported the highest average number of pillows (2.2), while Japan reported the lowest (1.1). 美國人均枕頭數最高（2.2），日本最低（1.1）。

About 65 to 80% of people in every country said they took steps to make sure their bedroom smelled the way they liked, except Japan, where only 28% cared enough to take any action. Regularly airing out the bedroom is important in Germany, with 96% saying they do it more than once a week. 各國65%-80%的人說他們都會給臥室添加自己喜歡的味道，除去日本，只有28%的人會關心臥室氣味並採取措施。經常讓臥室通風對於德國人而言非常重要，96%的德國調查者說他們一週不止一次會讓臥室通通風。
