CBD lengthens sleep but shortens ripples and leads to intact simple but worse cumulative memory

This study investigated how cannabidiol (CBD) impacts sleep and memory in rats. High-dose CBD increased non-REM sleep duration but altered sleep brainwave patterns by reducing the size and frequency of "ripples," key oscillations linked to memory consolidation. While simple memory (recalling individual facts) remained unaffected, cumulative memory (integrating complex information) declined after CBD use. These findings suggest CBD may benefit sleep quality but might impair specific types of memory processing, raising questions about its broader impact on cognitive function.

CBD may aid sleep but could impact complex memory processing. Individuals using CBD for sleep should be cautious about possible cognitive trade-offs, particularly for tasks requiring complex information integration. Consult a healthcare provider for tailored advice, especially before regular use. Additionally, maintain healthy sleep practices, such as consistent sleep schedules and reducing screen time, to support both memory and sleep quality.
