A 45-minute nap may boost brain health by clearing mental "noise" and improving memory, outperforming wakefulness, researchers say.
A 45-minute afternoon nap may significantly boost brain health and learning by resetting synaptic connections, according to a study by researchers from the University of Freiburg and the University of Geneva.
Using brain imaging and stimulation, they found naps reduced synaptic strength—clearing mental "noise"—and improved the brain’s ability to form new memories and adapt, outperforming an equal period of wakefulness.
Experts say this restorative effect enhances focus and performance, especially in demanding jobs, and recommend cognitive behavioral therapy over medication for chronic insomnia, which is often linked to stress and habits rather than biological issues.
Según los investigadores, una siesta de 45 minutos puede mejorar la salud del cerebro al eliminar el "ruido" mental y mejorar la memoria, superando el estado de vigilia.
