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.
Sleep not only consolidates memories but also resets the brain’s memory storage mechanism. This process, governed by specific regions in the hippocampus, allows neurons to prepare for new learning without being overwhelmed, opening potential pathways for enhancing memory and treating neurological disorders.
