Better to study shortly or long before for an exam? You'll be surprised!

Is it better to study months before an exam or in the previous days? A study reveals the best method!

Better to study shortly or long before for an exam? You will be surprised!

Are you one of those who study the day before the exam even though they have always advised you otherwise? Now, science says that you might be right to do so because studying when stressed or under pressure favors learning .

This is what scientists at the University of Bristol have said, discover that the hormones that are produced when stressed are causing changes in the cells, allowing memories to be stored more effectively in the hippocampus, the part of the brain related to memory.

According to the Professor Hans Reul, who directs the research, stress hormones, such as cortisol and adrenaline, change genes within neurons and increase their learning capacity .

This The phenomenon is called "epigenetic modification", an alteration of the genome of cells to reprogram DNA in the brain and thus increase or decrease some genes.

The scientist compares it to the fact that we always remember with more precise the situation It is unpleasant compared to the good ones.

“We often find that unpleasant memories are more remembered than pleasant memories.This is due to the role that stress plays in this area, since it is clearly important from a Biological point of view to remember something that hurts or threatens us ”says the scientist.

So, stress hormones bind to specific receptors in the brain that improve control of epigenetic mechanisms that are involved in learning and memory.

"Hormones drive these epigenetic control mechanisms and this leads to greater expression of the genes that facilitate the ability to memorize.So, essentially, stress hormones improve the process that normally leads to After learning, ”he says.

However, the doctor points out that too much stress can end up producing the opposite effect :“ When we are very stressed, it is not possible to collect all the new information in good condition.The brain enters a way in which the only thing it does is replace information with other information, since memory is not efficient.That is why long-term stress is also not good for the human being.”

You may study in The last moment is not always the most appropriate way, but if we do it from time to time, we surely notice that the concepts are more easily recorded or, at least, that says science.
