How Does Coffee Affect a Sleeping Brain?

How does coffee affect a sleeping brain?

Coffee can help you stay awake. But what does caffeine actually do to your brain once you're asleep? Using AI, a team of researchers has an answer: it affects the brain's 'criticality'.

Caffeine induces age-dependent increases in brain complexity and criticality during sleep

Caffeine is the most widely consumed psychoactive stimulant worldwide. Yet important gaps persist in understanding its effects on the brain, especially during sleep. We analyzed sleep electroencephalography (EEG) in 40 subjects, contrasting 200 mg of caffeine against a placebo condition, utilizing inferential statistics and machine learning. We found that caffeine ingestion led to an increase in brain complexity, a widespread flattening of the p…

Caffeine Rewires The Brain During Sleep — And Age Makes A Big Difference

That cup of coffee you had during dinner with friends didn't just keep you tossing and turning -- it fundamentally altered how your brain operated during whatever sleep you managed to get. The post Caffeine Rewires The Brain During Sleep — And Age Makes A Big Difference appeared first on Study Finds.

Caffeine Disrupts Sleep Brainwaves and Delays Nighttime Recovery

A new study reveals that caffeine increases the complexity of brain activity during sleep, especially in younger adults, potentially disrupting the brain’s ability to recover overnight. Researchers used EEG and AI to analyze sleep in 40 adults after caffeine or placebo intake, identifying less predictable brain signals and increased wake-like brainwave patterns.
