'Night Owls' Taking Morning Classes Get Poor Marks
Studying till late in the night will only fetch poor grades and it is high time to tailor students' class schedules to their natural biological rhythms, stress researchers. Students whose circadian rhythms were out of sync with their class schedules -- say, night owls taking early morning courses -- received lower grades due to "social jet lag," a condition in which peak alertness times are at odds with work, school or other demands.
"We found that the majority of students were being jet-lagged by their class times, which correlated very strongly with decreased academic performance," said study co-lead author Benjamin Smarr from the University of California-Berkeley.
To reach this conclusion, the team tracked the personal daily online activity profiles of nearly 15,000 college students as they logged into campus servers.
After sorting the students into "night owls," "daytime finches" and "morning larks" -- based on their activities on days they were not in class -- researchers compared their class times to their academic outcomes.
In addition to learning deficits, social jet lag has been tied to obesity and excessive alcohol and tobacco use, said the study published in the journal Scientific Reports.
"Our research indicates that if a student can structure a consistent schedule in which class days resemble non-class days, they are more likely to achieve academic success," said study co-lead author Aaron Schirmer, an associate professor of biology at Northeastern Illinois University.
Previous studies have found that older people tend to be active earlier while young adults shift to a later sleep-wake cycle during puberty.
Overall, men stay up later than women, and circadian rhythms shift with the seasons based on natural light.
Finding these patterns reflected in students' login data spurred researchers to investigate whether digital records might also reflect the biological rhythms underlying people's behaviour.
The results suggest that "rather than admonish late students to go to bed earlier, in conflict with their biological rhythms, we should work to individualise education so that learning and classes are structured to take advantage of knowing what time of day a given student will be most capable of learning," Smarr said.
"Different people really do have biologically diverse timing, so there isn't a one-time-fits-all solution for education," he added.

Strict security measures in place in Mumbai for Messi's events at 2 venues Dec 14, say police
Mumbai (PTI): In view of Argentine superstar footballer Lionel Messi's visit to Mumbai on Sunday, the city police are implementing stringent security measures, like not allowing water bottles, metals, coins inside the stadiums and setting up watchtowers to keep an eye on the crowd, officials said.
The police also said taking extra care to avoid any stampede-like situation and to prevent recurrence of the chaotic situation that unfolded in Kolkata during Messi's visit on Saturday as thousands of fans protested inside the Salt Lake stadium here after failing to catch a clear glimpse of the football icon despite paying hefty sums for tickets.
Messi is expected to be present at the Cricket Club of India (Brabourne Stadium) in Mumbai on Sunday for a Padel GOAT Cup event followed by attending a celebrity football match. He is expected to proceed to the Wankhede Stadium for the GOAT India Tour main event around 5 pm.
"In view of Lionel Messi's visit to Mumbai, the police are geared up and have put in place a high level of security arrangements in and around the stadiums located in south Mumbai. Considering the chaos that prevailed in Kolkata and the security breach, we have deployed World Cup-level security arrangements at Brabourne and Wankhede stadiums," an official said.
Expecting heavy crowd near the stadiums during Messi's visit, the city police force has deployed more than 2,000 of its personnel near and around both the venues, he said.
As the Mumbai police have the experience of security 'bandobast' during the victory parade of ICC World Cup-winning Indian team and World Cup final match at the Wankhede Stadium, in which over one lakh cricket fans had gathered, we are prepared to handle a large crowd of fans, he said.
"We are trying to avoid the errors that occurred in the past," the official said.
There is no place to sneak inside the stadiums in Mumbai like the Kolkata stadium, according to him.
The police are also asking the organisers to provide all the required facilities to the fans inside the stadium, so that there will be no chaos, he said, adding the spectators have purchased tickets in the range of Rs 5,000 to 25,000. After paying so much of amount, any spectator expects proper services, while enjoying the event, he said.
The police are expecting 33,000 spectators at the Wankhede Stadium and over 4,000 at Brabourne Stadium. Besides this, more than 30,000 people are expected outside and around the stadiums just to have a glimpse of the football sensation, he said.
The organisers responsible for Messi's India visit recently came to Mumbai to discuss security arrangements. During the meeting, the Mumbai police asked them not to take the event lightly, according to the official.
After those requirements were fulfilled, the final security deployment was chalked out, he said.
Police has the standard procedure of the security arrangements inside the Wankhede Stadium, where people are barred from taking water bottles, metals objects, coins. Police are setting up watch towers near the stadiums and there will be traffic diversions, so that there is maximum space available to stand, according to the official.
Police are also appealing to the spectators to use public transport service for commuting and avoid personal vehicles to reach south Mumbai.
To avoid any stampede-like situation, police are also taking precautionary measures and will stop the fans some distance ahead of the stadium and public announcement systems will be used to guide the crowd. Barricades will be placed at various places to manage the crowd.
In case the crowd swells up beyond expectation, the police will divert people to other grounds and preparations in this regard underway, he said.
Additional police force has been deployed in south Mumbai to tackle any kind of situation, he said.
