Caffeine and sleep EEG: a reader-friendly preview of a systematic review showing how caffeine subtly changes brain-sleep patterns without obvious awakenings.
Key Takeaways
- Caffeine intake reduces slow-wave activity during sleep, which impairs deep restorative sleep despite unchanged total sleep time.
- Changes in sleep EEG caused by caffeine include altered spectral power and microstructure indicative of less efficient sleep quality.
- Even without causing full awakenings, habitual or acute caffeine can disrupt physiological sleep processes important for recovery and cognition.
