Key facts
- Children with irregular sleep schedules showed lower cognitive performance.
- Inconsistent bedtimes and wake-up times were linked to poorer scores in language and memory tasks.
A recent study has found a correlation between irregular sleep schedules in preschoolers and lower cognitive performance. The research indicated that children who did not adhere to consistent bedtimes and wake-up times exhibited diminished scores in tasks related to language and memory. This suggests that the regularity of sleep, not just the duration, may play a crucial role in the cognitive development of young children.
