Purpose of review:
For the most part of human existence, individuals have been living a rural lifestyle in a rural setting. However, such sleep-conducive conditions have largely been transformed dramatically by urbanization within a relatively short span of time in recent history, and the resulting evolved mechanisms-environment mismatch is theorized to bring about an increased risk for insomnia symptoms. This brief review of the recent literature is designed to evaluate the veracity of this proposition.

Recent findings:
The majority of recent findings has suggested that most proposed evolutionarily-mismatched urban factors are indeed related to the presence of insomnia symptoms. However, there is a general paucity of longitudinal evidence (and for some other factors, enough evidence of any kind).

Although there is a preponderance of recent findings indicating a link between evolutionarily-mismatched urban phenomena and insomnia symptoms, more longitudinal data are needed before any causative conclusion can be drawn.
