How Your Evening Coffee Could Be Affecting Your Brain During Sleep? Study Finds Out
A new study published in Communications Biology by researchers from Universite de Montreal reveals that caffeine disrupts the brain's ability to recover during sleep by increasing neural complexity and reducing restorative brain rhythms-effects that are especially pronounced in young adults. The findings suggest that caffeine, though beneficial for alertness during the day, may impair nighttime recovery and memory consolidation, prompting researchers to call for more personalized guidelines on caffeine intake based on age and health.
Caffeine is found not only in coffee but also in tea, chocolate, soft drinks, and energy drinks, making it the most widely consumed psychoactive substance globally. While its daytime stimulating effects are well documented, its nighttime impact on the sleeping brain has remained largely underexplored.
To address this, the research studied 40 healthy adults using electroencephalography (EEG) and artificial intelligence. Each participant underwent sleep monitoring on two occasions: once after taking caffeine capsules three and one hour before bed, and once after taking a placebo.
