[Beatriz9]

This is not a brain myth! Researchers at the Wisconsin Institute for Sleep and Consciousness at the University of Wisconsin-Madison studied mice to observe what happens to their brains while they sleep. Dr. Chiara Cirelli and Dr. Giulio Tononi found an 18% decrease in the size of synapses after a few hours of sleep. Don’t worry, though—this nighttime brain shrinkage actually helps your cognitive abilities.
