Go ahead on sleep on it– it could help you make a better decision. Bristol University researchers monitored the electrical activity in the brains of study participants, ages 20 to 91, as they carried out two tasks. They practiced the tasks, and then either stayed awake or took a 90-minute nap before repeating the same challenges. The data showed reaction times for the subjects who had slept were much quicker, while those who didn’t sleep showed no improvement in reaction time. The finding suggests information acquired during wakefulness may potentially be processed in some deeper way during sleep.
