A new study published this week reinforces what sleep scientists have long suspected: the quality of your deep sleep matters more than its duration when it comes to forming durable memories.
Researchers tracked slow-wave EEG activity in over 200 adults and found that participants with more consolidated slow-wave sleep performed significantly better on next-day recall tasks.
The findings add to a growing body of evidence that protecting deep sleep — by limiting alcohol, late caffeine and irregular schedules — is one of the most reliable cognitive interventions available.
