No one enjoys being awakened in the middle of the night, but having your sleep disrupted could be much more than just an annoyance. A new study conducted by The Stanford University found that broken sleep could affect your ability to build and retain memories. In order to prove this notion the researchers used a group of mice as their subjects and woke them up during sleep with bright light pulses. Afterwards the mice were put into a box with two objects, one they had seen before and one that they had not.
Only the mice who had experienced the broken sleep were equally interested in both objects, seeming as if they had never encountered either one. The mice who had not experienced interrupted sleep only examined the new object. One sleep expert suggested that the deep sleep period is when people sort through the happenings of the day and lock down important memories, and without this significant memories could be forgotten.
