Sleep: And then there was light!

Electricity access in previously unexposed communities delays sleep and reduces sleep duration by about an hour in rural communities, while in urban communities it only delays sleep.

• Why it matters: The study addresses how gaining electricity changes sleep patterns across different living environments, where effects may differ between rural and urban settings.
• What they did: Researchers compared sleep timing and duration after electricity introduction in rural versus urban communities that had not previously had access.
• The result: The findings suggest electricity exposure is linked to shorter sleep in rural areas and to delayed sleep in both settings, informing how electrification may affect health.
