Sleep and college grades go hand in hand

New Delhi, Oct 02 (ANI): Sleep and grades go hand in hand. Yes, researchers in a new study have found a strong relationship between a student's grades and their sleep time. What time students go to bed and the consistency of their sleep habits also make a big difference. It also states that getting a good night's sleep just before a big test is not enough -- it takes several nights in a row of good sleep to make a difference, according to the study published in the journal 'Science of Learning'. Researchers incorporated 100 students in an MIT engineering class who were given Fitbits, in exchange for the researchers' access to a semester's worth of their activity data. Researchers were also trying to find a correlation between physical exercise and the academic performance of students. In addition to having 100 of the students wear Fitbits for the semester, they also enrolled about one-fourth of them in an intense fitness class. There wasn't any relation. Those without the fitness classes performed just as well as those who did take them. He speculated that the intervals between the fitness program and the classes may have been too long to show an effect. Another surprising finding is that there appears to be a certain cutoff for bedtimes, such that going to bed later results in poorer performance, even if the total amount of sleep is the same.
