The academic performance of students is a factor that has a considerable influence when a study is conducted on the causes and consequences of studying from a very early schedule. We know that today's students face long and demanding study days, which usually start early in the morning and extend into the afternoon or even at night. Due to such strict and rigid schedules, we observe how many of them are affected both in their mental and physical health. The lack of adequate rest negatively impacts their overall well-being, causing them to be unable to replenish the energy needed for optimal performance in class.

Students, in many cases, are not resting the number of hours they really need for their age and stage of development, which directly affects their ability to comprehend and absorb the information included in their classes. As a consequence, their academic performance is compromised and the degree of comprehension of the subjects discussed in class decreases considerably. This also generates a drop in their grades, which in turn becomes a source of stress and anxiety, generating a cycle where academic pressure impacts both their emotional state and their ability to discover.

Analyzing how various study regimens affect students is the aim of this study. We propose to investigate whether it is really indispensable for study to start so early, or if, on the contrary, There is potential for improvement in students' academic performance and general well-being by adjusting the start of classes to a later time. By allowing students to rest and improve the quality of their sleep, it is expected that they can also improve their understanding of content and optimize their academic performance, thus contributing to a healthier and more effective learning environment in the different educational institutions.
