New Place, Sleep Woes? The First-Night Effect Explained
11 Aug
Summary
- The first-night effect causes less sleep and more awakenings in new places.
- An evolutionary adaptation keeps part of the brain alert in unfamiliar settings.
- While common, strategies exist to mitigate sleep disruption when traveling.
Many travelers find their sleep patterns disrupted in new locations, a common experience called the first-night effect. This phenomenon, supported by numerous studies, is thought to be an evolutionary adaptation where the brain stays partially alert in unfamiliar environments. Researchers suggest that this vigilance leads to less overall sleep and shallower rest.
The effect is more pronounced in children, adolescents, and older adults, while those in their twenties are typically least affected. While the brain may not consciously perceive danger, it acts as if it does, leading to reduced sleep quality. This protective mechanism can persist until the second night in a new setting.
While evolutionary vigilance plays a role, other factors like travel fatigue or environmental disturbances can also impact sleep. Conversely, some may sleep better in new places if detached from home stressors. Managing anxiety and practicing consistent sleep hygiene, such as maintaining a dark, cool room and a pre-sleep routine, are recommended strategies to improve rest while traveling.
