Many of us have had this experience: we lie down in a bed other than our own, perhaps at a friend’s house or in a hotel room, and find it difficult to fall asleep.
Why does it happen?
A new study shows one reason is what the scientists call “first night effect”. They believe that one side of the brain acts as a “night watch” to warn us about possible dangers. It prevents us from getting to sleep on the first night in a new environment.
For the study, 35 young volunteers were asked to sleep in a sleep lab for several days as researchers watched their brain activities.
According to the researchers, on their first night, the left brain was more active than the right brain and people had a hard time sleeping. However, the left brain activity decreased(降低) as days went by, falling even to the point of complete calm. In this process, the volunteers got better and better sleep experience.
The findings show that the different rhythms(节奏) of the sides of the brain affect our sleep. When the two sides work differently, the balance between them is broken. So the brain can’t relax and is sensitive(敏感的) to anything strange around.
“At some level, the brain is continuing to work, even though you don’t realize it,” US professor Jerome Siegel told Smithsonian Magazine. “If something unusual happens, you can be alert(警惕的)”.
More surprisingly, this is like the way some animals sleep. Whales, dolphins, and many birds can sleep with half of their brain while the other half stays awake, with one eye staying open.
The researchers think that it is the result of evolution(进化) and works to protect us in possibly dangerous environments.
If you have ever had first night effect, researchers advise you to bring your own pillow or sleep in a room similar to your bedroom next time you sleep away from home.
