Sleep Locks In Bad Memories, Emotions

Researchers from the University of Massachusetts at Amherst asked more than 100 healthy adults to rate their emotional responses to a series of images, some depicting unsettling scenes. Twelve hours later, they rated the images again. The difference: Half of the subjects slept during the break; the other half did not.

"It's true that 'sleeping on it' is usually a good thing to do," said Spencer, citing evidence that sleep boosts memory and other cognitive functions. "It's just when something truly traumatic or out of the ordinary happens that you might want to stay awake."
