Short sleep before the exam is better than trying to cram

If you have ever or are going to go through an important exam soon, this study certainly reminds you that the most important thing to do before each test is not to try to cram all the knowledge but to have one. So refreshing nap.

In fact, so far, researchers have not been sure about why there is such a phenomenon. But they think that a nap can be a way to reinforce memory, making them longer stored in each of our brains, as opposed to trying to cram knowledge only in short term

According to ScienceAlert, a research group from Duke-NUS Medical School, Singapore recruited 72 volunteers, all of whom were taught unfamiliar topics related to ants and crabs within 80 minutes.

A nap can be a way to strengthen memories, making them longer stored in each of our brains.

The study participants were then divided into three groups and they were able to choose a form of rest, such as watching a movie, taking a nap or reviewing the lesson, before continuing on to a lesson Learn another 80 minutes on this topic.

After the second lesson, a group of volunteers was given a test to assess the knowledge gained from previous lessons. The results were quite surprising when those who had taken a nap had the highest score.

In an experiment that was repeated a week later, those who were in short sleep continued to keep the highest score. Another interesting finding, those who try to review with higher scores than those who watch the film in the first test, only have the same score as the viewers in the second test.

Researcher James Cousins ​​affirmed to New Scientist: "It can be seen that cramming information may be good and appropriate in the short term but in the long run, their benefits may never be as good as expected. " .

The stuffing of information in the long run, their benefits can never be as good as expected.

The advice of Cousins ​​for students before each exam is quite simple: " Don't try to get yourself stressed by sitting in the head with lots of information. Take a short nap, that's really a good thing." more ".

However, because the research scale is still quite narrow and the distance is close between those who sleep short or try to study before taking the test in a few results, so the research team confirmed not to rush to draw accurate conclusions. The group hopes to continue to conduct larger-scale research to reinforce and verify the argument.

A study in 2015 showed that the relationship between sleep and memory status improved remarkably. Participants in the word test when taking a nap have twice the chance compared to those who try to cram information and can fall asleep during the exam.

Take a short nap, that's really the best thing.

Other research from Brazilian researchers suggests that sleep improves or weakens synaptic connections in the brain. This is a quite specific and intelligent mechanism of the brain. When information connections are analyzed by the brain as useful, they will continuously be strengthened and maintained, while misinformation, little use or unimportant brain analysis will be eliminated. give up to make the information flow more smooth.

Above all, the most important thing is to get the right rest and moderation. Because you will not be able to get a good test result if your body and brain are not fully rested.

The study by Singapore scientists once again reinforces the argument of many previous studies on the effect of naps on the brain, especially improving alertness and thinking ability. academic.

The results of the study were presented at the annual meeting of the American Neurology Association last week.
