Why We Sleep So Poorly In Unfamiliar Places

Many of us have trouble sleeping in an unfamiliar place, like a hotel, or a friend’s house for the first time. When we finally do get to sleep, it’s often fidgety and disturbed. New research shows that one hemisphere of our brain stays more active during the first night of sleep—and it does so to keep us ready for trouble.

It’s a phenomenon scientists refer to as the “first-night-effect.” A neuroimaging study by Brown University researchers reveals that, under these “first night” conditions, one hemisphere of the brain stays alert. “This half-asleep, half-awake state may work as a way to monitor unfamiliar surroundings,” study co-author Masako Tamaki told Gizmodo. The paper has just been published in Current Biology.
