Part 3/7:
Unraveling the Link Between Sleep and Academic Performance
The findings revealed by the data presented a straightforward conclusion: sleep is paramount to academic success. The researchers documented a direct relationship between the amount of sleep students received and their performance in exams and tests.
The Cut-Off Time
One of the studies’ most striking revelations was that there exists a "cut-off time" for going to bed. Contrary to common assumptions, the later a student stays up, the worse their academic performance becomes—this is true even if they attain the same total hours of sleep as those who retire earlier. The threshold appears to be 2:00 a.m.: students who sleep past this time tend to experience diminished performance, irrespective of their total rest.
