Question

During sleep, your brain uses this "down" time to process things you have learned. According to Harvard's Healthy Sleep website (healthysleep.med.harvard.edu), when we have gone without sleep for some time, "our focus, attention, and vigilance drift, making it more difficult to receive information" (Sleep, 1). We lose our ability to remember or recall previously learned information if we do not get enough sleep. The article further states that researchers believe going without sleep can reduce your ability to learn new things.
