Lack of Sleep Has Impact on Student Grades
There is a high correlation
between student grades and the consistency of their sleep, according to a study
done by two professors at MIT. A study was conducted among 100
students of MIT who had to wear Fitbits, the popular wrist-worn device that
tracks a person's activity 24/7. Students who went to sleep after a threshold
time say 2 am repored lower performance in tests although they got the required
sleep hours for their age.
However, there was no correlation between the performance of those who participated in fitness classes and their performance in examinations. It was believed that fitness or regular excercise has impact on cognitive performance.
The study also revealed no improvement in scores for those who made sure to get a good night's sleep right before a big test. According to the data, "the night before doesn't matter," Grossman says. "We've heard the phrase 'Get a good night's sleep, you've got a big day tomorrow.' It turns out this does not correlate at all with test performance. Instead, it's the sleep you get during the days when learning is happening that matter most."
