Have you ever had trouble sleeping when you are in a new place? Do you toss and turn or easily wake when you travel or sleep somewhere other than your own bedroom? If so, you are not alone. According to a new study published in the journal “Current Biology,” it is a very normal occurrence for your first night’s sleep in new surroundings to be less than satisfactory.
Researchers at Brown University found that, similar to some animals, only half of the human brain “sleeps” the first night a person sleeps in a new environment. Research showed that the left hemisphere of the brain, the more logical and analytical side, was still actively “awake” throughout the night. The researchers believe that it is our brain’s way of “keeping watch” in unfamiliar territory. Though humans no longer worry about predators lurking in the darkness, our brains evolved during a time when that threat was very real.
So next time you are traveling or house sitting, plan accordingly, because your first night of sleep away from home will most likely not be as good as usual.
