If you have a big test coming up, you may want to study right before bedtime!
A recent study shows that not only does sleep help protect memories from outside interference it also helps strengthen them. The study found that people who went to sleep after learning the supplied information performed better on a test than those who didn't snooze after studying.
Researchers believe this information could be useful in understanding sleep disorders and memory problems. All this according to the American Academy of Neurology.
