The favorite stimulating products of the students, among them the coffee or the maté, they allow several hours to pass without sleeping and this can be harmful when surrendering exam. “Although there are studies that show that the caffeine (active ingredient of both infusions) it improves the memory, the lack of dream it can counteract the effect”, Jorge Medina, investigator of the National Council of Scientific and Technical Investigations points out (Conicet), in the Ability of Medicine of the University of Buenos Aires, Argentina.

For Francisco Zaragoza, professor of pharmacology of the University of Alcalá, Spain, “students' cases have been given that they fail in the exams because the dream returns them when they are surrendering”. to Review in the pillow The specialists says that to sleep the previous night at least six hours it allows to consolidate the learned knowledge. “During the dream, the brain makes a replay of the activity that was carried out; in some way it is as if he read the texts again”, Medina adds who studies in its laboratory the bases neuroquímicas of the learning and the memory.

The owls and the hens
In the last decade it was clear that two types of people exist: the owls that reach the maximum of concentration during the night, and the larks (or hens) that are only very watchful in the tomorrow's first hours. The scientists recommend to choose the hour of study according to that biological command, but without seeking to stretch the day by force of sumps of coffee. “It is necessary to approach the most difficult matters in the hours in that it is easier to stay concentrated”, he suggests Daniel Navarro, psychologist of the University Of Alcalá de Henares of Madrid, Spain.

Thierer recommends and Navarrese: To not study more than eight or twelve hours per day. To begin each study day with that that better it is known, in way of generating trust in oneself. To concentrate on the text during 45 or 50 minutes, and to make “recesses” of ten minutes, in those that it suits not to fix the view in anything. To eliminate of the study place the elements of distraction, like magazines. To already be met during the last days to outlines and summaries facts, in way of “to guarantee the memory.” To sleep at least six hours before the exam.
