Good Sleep Improves Memory
| Quote: |
Have you ever felt as if you think and memorize more clearly after a good sleep?
According to Harvard Medical School researchers, people who acquire adequate sleep are more likely to have better memories than people who do not get much sleep.
In a study, people were tested to see how well they remembered word pairs after being awake all day. Those with a good night's sleep had significantly higher scores than those who were awake all day.
``There was a very large benefit of sleep for memory consolidation, even larger than we were anticipating,�� said study author Jeffrey Ellenbogen, an associate neurologist at Brigham and Women�s Hospital in Boston and a postdoctoral fellow in sleep medicine at Harvard Medical School.
The researchers focused on sleep�s impact on a certain type of memory called ``declarative�� memories, which refer to those dealing with certain facts, episodes and events.
The research involved 48 healthy people between the ages of 18 and 30 who were divided into four groups. Two groups were presented with word pairs at 9 a.m. and then tested at 9 p.m., with one of the groups also receiving the new list of word pairs immediately before the testing. The other two groups followed the same pattern, but were presented with the list at 9 p.m. and then tested at 9 a.m., following a full night�s sleep.
The sleep group tested without the competing word list performed 12 percent better than the wake group tested without the interference. The sleep group tested after the interference scored 44 percent better than the wake group tested after the competing list was presented.
The analysis of the data showed that the memory of those people who had a quality sleep was overall better than the memory of those participants who slept poorly.
The researchers believe this shows sleep not only improves memory, but also helps protect memories from competing information or interference.
``We sought to explore whether sleep has any impact on memory consolidation, specifically the type of memory for facts and events and time,�� Ellenbogen said.
``We know that sleep helps boost memory for procedural tests, such as learning a new piano sequence. But we�re not sure, even though it�s been debated for 100 years, whether sleep impacts declarative memory.��

I've found that trying to explain the importance of a good night's sleep has always fallen on deaf ears if those ears are attached to a Korean head. Hopefully, these attitudes will start to change.
