SLEEP PRESERVES MEMORY

Previously, studies have established that sleep enhances procedural memory, the process involved in consolidating procedural skills ( typing or playong the piano, for example ),
A new study by Jessica Payne, from the Beth Israel Deconess Medical Center ( Boston, Mass )
And colleagues now show that sleep is important in the development of episodic memories, paarticularly those of an emotional nature. The study involved 88 college students an found that the subjects who slept a full evening remembered the emotional scene they were shown in far greater detail than those participants who stayed awake for 12 hours after viewing the scene.

Comments the researchers : "Sleep is a smart sophisticated process, sleep is actually working at night to decide what memories to hold on to and what to let go of.
Dr. Klatz remarks: " In that to little sleep has been found to impair many of the body's biological
Processes, including the immune system, metabolic function, cognitive performance (specifically, learning and memory), And more, this study shows the key role of sleep in preerving memories of an episodic and emotional nature. The Restorative role of sleep is often underestimated and this study reminds us of the importance of this nightly process".
