Happy calm smiling man having a rest after solving all the tasks at workWhen we sleep, our brain goes through a lot of processes to help us on the acquisition of new knowledge next day. But, what happens when we don’t sleep enough? It may impact seriously on your academic performance

How many times you stayed overnight studying for an exam you’d have next morning? This practice is common in the university, when the student feels the day lacks hours to complete his academic goals and exams. However, this may be counterproductive.

Rest is also important to understand and hold what was learned. “A night without sleeping can reduce the ability to assimilate knowledge by almost 40%, since the cerebral regions involved in the storage don’t function in a proper way if there’s a lack of sleep”, says an analysis done by researchers of the University of Berkeley in California.

 What are the best hours to study?

It is a real debate to determine what is the best moment to study and when to sleep. On the one hand, researchers of the University of Nevada concluded in 2017 that the best hour range to study starts at 11:00 in the morning and finishes at 21:30 in the night This position is shared by a previous research, done in 2008 by researchers of the Hospital of Quiron in Valencia, Spain, who indicated that the first hours of the day are not the most suitable to study, because you are still under the influence of sleep.

The situation is even worse for the younger students. During the adolescence 9 to 10 hours of sleep per day are required, says the article “Sleep in school children and teenagers, its importance and promotion through educational programs”, published in the Pediatrics Chilean Journal in 2013.

Why studying at night is a bad idea?

Exhaustion: After 18:00 in the evening, the brain is tired and works with reduced efficiency. Drinking coffee or energetic drinks won’t work, because they create a false sensation of being awake that doesn’t counter the possibility of being distracted.

Insomnia: If you took a stimulant, sleeping will be an impossible mission. Besides, anxiety for the exam next day may keep your brain active, making it more difficult to sleep.

Complications: Studying under pressure at the last minute will be overwhelming and may make understanding a subject more difficult, in comparison to studying with your brain rested.

Experts of the University of California in the US arrived to the conclusion that the best performance is achieved when there is an equilibrium between hours dedicated to study and the time you dedicate to sleep. That is why you should establish a schedule to study, and take the time to rest at night.
