A new study discussed in an article in HealthDay News shows that “Sleep is not just for the body. It’s very much for the brain,” said the author of the study, Matthew Walker, an assistant professor at University of California at Berkeley.

The findings are preliminary, and the study was small, but the results show that a nap can be helpful for memory. In the study, 39 young adults were divided into two groups. Both groups participated in a memory activity at noon one day in which they were shown face and had to link them with names.  Following this activity, 20 of the participants took a 100 minute nap. At 6pm, they all took part in another memory exercise.

The participants who did not nap performed about 10 percent worse on the activity as compared with those who took naps. This shows that non-dreaming sleep can help improve memory. Sleeping for longer periods of time is also important to allow your brain to go through the many cycles of sleep.
