Have you ever had trouble sleeping in a new place?

你在新地方睡觉有过困难吗？

Lots of people do. And now researchers from Brown University in Rhode Island think they know why.

很多人都有。现在，罗德岛布朗大学的研究人员认为他们知道了原因。

They found that one-half of the brain "remains more awake" than the other half when people are trying to sleep in a new place.

他们发现，当人们试图在新的地方睡觉时，大脑的一半比另一半“保持清醒”。

This appears a case of the brain keeping people ready for trouble in a new place, the researchers said.

研究人员说，这似乎是大脑让人们在一个新的地方为遇到麻烦做好准备的一个例子。

The researchers said many people report they have a harder time sleeping the first night at a hotel or other places outside their home. They call it, the "first-night effect".

研究人员说，许多人报告称，他们在酒店或家外其他地方的第一晚睡眠困难。他们称之为“第一夜效应”。

Why You Don't Sleep As Well

in a New Place 初夜效应

When we sleep in new places, half of our brain stays awake.

The first-night effect of difficulty in sleeping in a new place happens because of our brain's natural instinct. This instinct of safeguarding ourselves from the harms that might be present in a new environment is the reason why you don't sleep well.

"In Japan, they say, 'if you change your pillow, you can't sleep,''' said Yuka Sasaki, one of the report's authors. "You don't sleep very well in a new place. We all know about it."

“在日本，人们说，'如果你换了枕头，你就睡不着了，’”该报告的作者之一佐佐木由香说，你在新地方睡不好。我们都知道。"

The researchers measured brain waves for 35 volunteers over two nights in a laboratory. The two nights were a week apart.

研究人员在实验室的两个晚上测量了35名志愿者的脑电波。这两个晚上相隔一周。

They found during the first night the left hemisphere of the brain was more active than the right hemisphere. This was during the first deep-sleep period, the researchers said.

他们发现，在第一个晚上，大脑的左半球比右半球更活跃。研究人员说，这是在第一次深度睡眠期间。

Sasaki said a lot of questions remain. Researchers did not keep measuring brain waves all night long.

佐佐木说，还有很多问题。研究人员并没有整晚都在测量脑电波。

So, they don't know if the left hemisphere keeps "watch" all night. Or whether it "works in shifts" with the right hemisphere later in the night.

所以，他们不知道左半球是否整夜“监视”。或者它是否在晚上晚些时候与右半球“轮班工作”。

They also do not know why the extra brain activity, at least during the first phase of deep sleep, is always on the left hemisphere.

他们也不知道为什么额外的大脑活动，至少在深度睡眠的第一阶段，总是在左半球。

For some, this research may be calming. It is good to know that our brain is "looking out for us," in a new place.

对一些人来说，这项研究可能会让人平静下来。很高兴知道我们的大脑在一个新的地方“照顾着我们”。

But it may not help with sleep. That extra brain activity, at least according to this new research, makes it harder to get the sleep people need to wake up well-rested in the morning.

但这可能对睡眠没有帮助。至少根据这项新的研究，额外的大脑活动使人们更难获得早上醒来时充分休息所需的睡眠。

Basic Sleep and Relaxation Tips

Stick with a Routine

You probably already have a pre-bed routine, and now isn’t the time to tweak it. Be sure that one of the first boxes you unpack contains everything you need for your normal bedtime ritual including familiar bedsheets and your favorite pajamas.

Wind Down

If you find you can’t sleep in a new place, make a plan to go to bed 30 minutes early. Dim the lights, put away the electronics and engage in an activity that relaxes and calms your mind—it could be writing in a journal, meditating, sipping chamomile tea, or reading a book.

Block Potential Distractions

It takes time to learn the quirks of a new place. What are those creaks and squeaks? What kind of light will be coming in the windows each morning? Until you know exactly what to expect, it’s a great idea plan ahead for any potential sleep disruptors. On the first day in new house, install at least temporary window treatments to block out any street lights and morning sunbeams, and set up your smart speaker so you’ll have some white noise those first couple of nights.
