Want to Bump Up Your Memory? Have Lots of Sleep, Says New Study

Late night parties, night shifts, football matches, and so many other things keep us up all night. We don’t pay much attention to our sleep patterns or sleep deprivation as we stay way too busy with other “significant” stuff of our lives.

However, a new study has shown that sleep is as important as one can think of. Not only does good sleep give us a fresh look, but British and Spanish scientists have found that it helps to sharpen our memory as well.

Researchers from the University of Exeter and the Basque Centre for Cognition, Brain and Language said that proper sleep helps one to recollect information that one couldn’t remember while awake.

In the research, they noticed that over the span of 12 hours subjects couldn’t remember information if they stayed awake, but a night’s sleep encouraged entry to those tinges of memory that had earlier been difficult to regain.

The researchers followed the memories of these subjects for new and cooked-up words, the latter learnt either before a night’s sleep or a similar duration of sleeplessness. Subjects were enquired of the words straightaway after the introduction and then again after the duration of sleep or sleeplessness.

The chief difference was between those new word memories that the subjects could remember both at the instant test as well as the 12-hour retest, and those not remembered at the instant test, however ultimately remembered at the retest.

The researchers discovered that in comparison to daytime sleeplessness, sleep encouraged to recollect unrecalled memories more than it ceased memory loss.

Nicolas Dumay associated with the University of Exeter and an honorary staff scientist at Basque, illustrated that sleep nearly boosts two-fold increase of our possibilities of remembering earlier unrecalled things, and the boost in memory accessibility after sleep may show that certain memories are polished overnight.

He added, “This supports the notion that, while asleep, we actively rehearse information flagged as important,” stressing that further research is required to understand the functional importance of this experiment and if, for example, “it allows memories to be accessible in a wider range of contexts, hence making them more useful.”

The report said that positive effects of sleep on memory is very familiar in that that it helps us to remember the things we did, heard or said, the previous night. However, sleep’s impact on sharpening memory and making the latter more reachable albeit discovered needs to be fully investigated.

Dumay explained the mechanism of the whole sharpening of memory process, in the report. He said that the memory bump up arrives from the hippocampus – an inner structure of the temporal lobe, and unraveling recently encrypted episodes and rerunning them to the areas of brain, fundamentally engaged in bagging them. He believes this would direct the subject to effectually re-experience the chief events of the day.

The study was published in the journal “Cortex”.

According to a report by, sleep not only makes our memory strong, but it makes an individual live longer too. It said that a 2010 study on women between the ages of 50 and 79, it was discovered that those who got less than 5 hours or more than six and half hours of sleep, suffered more deaths.

The report also informed that sleep help curing inflammation which is a sign of cardiovascular diseases, triggers creativity, boosts up stamina and less daytime fatigue, polishes attention and eradicated depression.
