We all know that we get increasingly tired over the course of the day. Psychologist Angela Anguita explains that "taking advantage of the early hours of the morning means that we have enough energy to carry out our task, provided that we have got enough rest the night before. If you haven't got a good night's sleep, rest first and then study in the afternoon". Javier Taborda, a professor in the Department of Educational Studies at Caldas University in Colombia, says that, for studying, "the best time is in the morning between 7/8 am and midday".
In any case, as demonstrated by a study conducted at the University of California, Los Angeles (UCLA), optimal performance "is achieved when there is a balance between study and sleep time". While many students may focus better at night, it is important to recuperate the hours of sleep missed by staying up and studying. Ultimately, it is important to listen to your body and to adjust the general techniques to the characteristics of different times of the day.
