Planning classes in line with biological clocks could improve students' grades



New US research has found that students whose class schedules are out of sync with their biological rhythms see their academic achievement as suffering.

Performed by researchers at the University of California, Berkeley and Northeastern Illinois University, It is believed that the study is the largest social jet lag survey to date using real-world data.

Social jetlag is caused when a malposition occurs between your activity and your natural biological rhythm in the morning, when you are not in high alertness, for example. It has been linked to a variety of health problems, including obesity and depression, as well as alcohol and tobacco use.

The team studied the online daily activities of 1

4,894 Northeastern Illinois University students logging in and out of the campus server for two years.

Based on their activities on days when they were not in class, the students were divided into three groups: "Night owls," "Day finches," or "Dawn."

The researchers then compared The results show that the majority of students had schedules that did not match their circadian rhythms – for example, revelers who took courses early in the morning – resulting in lower scores leading to social jet lag.

50 percent of students took classes before they were fully alert, and another 10 percent already had in alertness before the classes began.

The remaining 40 percent of st students had schedules that were mostly synchronous with their biological rhythms, and showed better class performance and higher GPAs.

The team found that night owls were particularly affected by social jet lag and many were unable to do their best

"Because owls are later and classes are earlier, this mismatching relationship strikes owls hardest, but We see larks and finches, who later take classes and also suffer from the mismatch, "said co-lead author Benjamin Smarr. "Different people really have a biologically diverse timing, so there is no one-time solution to education."

Study co-lead author Aaron Schirmer added, "Our research shows that if a student can form a consistent schedule in which classes resemble days-non-class days, they are more likely to achieve academic success."

Experts exploring sleep patterns among younger students have also suggested postponing school starts to late morning for both health and school performance as teens get more sleep.

The results were published in the journal Scientific Reports.
