Research results that early morning lectures are associated with poor sleep and poor academic performance in college students
When you were a student, there must have been many people who overslept and skipped out on days when they had lectures in the first period, which started early. A research team in Singapore investigated early-morning lectures and the attendance rate and sleep time of university students, and found that ``if there is a lecture in the early morning, the sleep time of university students will be shorter, the attendance rate will be lower, and academic performance will decline.'' Research results were shown.

It is important to get a good night's sleep and attend lectures to get good grades. . Early morning lectures can be a huge disadvantage for college students, as lack of sleep can damage the mind and body, and poor academic performance can have a negative impact on employment opportunities.
Therefore, a research team at
The research team also tracked 181 college students for six weeks and investigated the time they woke up, the time they went to school, and whether they were able to attend the first lecture. In this survey, it was found that about one-third of the lectures that started at 8:00 a.m. were delayed or absent, and that students fell asleep more frequently on days when the first lecture was held in the morning. was also confirmed to be high. On the other hand, few university students were late for lectures that started after noon.
In addition, the research team estimated the sleep time of 39,458 college students from the login history of the learning management system, and aggregated the sleep time of the day for each time period when the first lecture was held.
In the figure below, graph ``a'' shows the percentage of college students logging in to the learning management system on the vertical axis and the time on the horizontal axis, and graph ``b'' shows the sleeping hours of the day with colored bars. , where the gray bars represent the average hours of sleep on non-lecture days. For both a and b, from top to bottom, the data for the days when the lectures start at 8:00, 9:00, 10:00, 11:00, 12:00, 14:00, and 16:00 are on average. They slept 5.9 hours, well below the average sleep time of 6.8 hours on a non-school day. The average sleeping time is 6.3 hours when the lecture starts at 9 o'clock, 6.5 hours at 10 o'clock, 6.9 hours at 11 o'clock and 12 o'clock, 7.2 hours at 14 o'clock and 16 o'clock, and the time when the lecture starts It can be seen that the earlier the sleep time, the shorter the sleep time.
In addition, when the research team analyzed the grades of college students and the presence or absence of lectures in the morning, it was found that there was a negative correlation between the number of days with lectures in the morning and grades. The research team said, ``Early morning lectures are often planned to maximize resources such as classroom space and the amount of time teachers spend lecturing, and to minimize conflicts between student and faculty schedules. 'Our results show a trade-off between early morning lectures and college students being more likely to be absent, sleep less, and have lower grade point averages,' he concluded. I'm here.
