Scientists warn of 'global sleep crisis' due to social pressures

May 7, 2016

Washington, May 7: Social pressures are forcing people to cut back on their sleep, contributing to a "global sleep crisis," according to a new study based on research collected through a smartphone app.

ScientistsIt enabled scientists from the University of Michigan to track sleep patterns around the world -- gathering data about how age, gender and the amount of natural light to which people are exposed affect sleep patterns in 100 countries -- and better understand how cultural pressures can override biological rhythms.

"The effects of society on sleep remain largely unquantified," says the study published Friday in the journal Science Advances.

"We find that social pressures weaken and/or conceal biological drives in the evening, leading individuals to delay their bedtime and shorten their sleep."

Lack of sleep is mostly affected by the time people go to bed, the study found.

Middle-aged men get the least amount of sleep, less than the recommended seven to eight hours.

And age is the main factor determining amount of sleep. The research is based on data collected through the free smartphone app Entrain, launched in 2014 to help users fight jetlag.

Scientists asked some 6,000 people 15 and older to send anonymous data about sleep, wake-up and lighting environment, enabling the scientists to obtain a large amount of data about sleep patterns worldwide.

The app also asks users to input information about their ages, gender, countries and time zones. Sleep is driven by an internal "circadian" clock, a cluster of 20,000 nerve cells the size of a grain of rice located behind the eyes, and adjusted according to the amount of light captured, especially natural light.

The average amount of sleep in the world varies from a minimum of seven hours 24 minutes in Singapore and Japan to a maximum of eight hours 12 minutes in the Netherlands, the study found.

Although a difference of 48 minutes may seem inconsequential, a lack of sleep for half an hour can have significant effects on cognitive function and health, the researchers said.

People who need sleep suffer a reduction in their cognitive abilities without really being conscious of it, the new study says. "Impaired sleep presents an immediate and pressing threat to human health," it says.

Bengaluru, May 23: SSLC and PUC students residing in containment zones will not be able to write the exams scheduled to be held in June and July, respectively, but will be given opportunity to write the supplementary examination and treated as fresh candidates.

Primary and Secondary Education Minister S. Suresh Kumar announced this at a press conference on Friday.

In turn, officials in the Department of Primary and Secondary Education will start collecting the list of students in containment zones. However, they are worried since the list of containment zones is dynamic and a particular locality can be declared a containment zone even the night before the examination.

“If any examination centre is located in the containment zone, then we can change the centre and move it to a non-containment zone. However, if a student resides in a zone that is declared containment zone just before the exam, there is no option but for the person to skip the exam,” an official said.

Officials of the department are worried about another scenario as well. “There is a chance that midway through the examination, an area is becomes a containment zone. Then some students may write a few papers and give the rest a miss. Implementation at the district- and block-levels will be a challenge,” said an official.

Sources said that the department is working out several situations that may arise and trying to work on providing practical solutions to the students.

Around 5.98 lakh students have registered for the second pre-university English examination that is scheduled to be held on June 18. As many as 8.48 lakh students have registered for the SSLC examination scheduled to be held between June 25 and 4 July. Currently, there are 261 containment zones in Karnataka that have 5.49 lakh people residing in these zones.

Meanwhile, the Karnataka Secondary Education and Examination Board has decided to ensure that only 18 students are seated in a classroom to write the SSLC examination. This is to ensure that social distancing is maintained in the exam hall.

Bengaluru, Jan 23: An alleged low-intensity blast on Wednesday late evening in Shanthinagar left three-time Congress MLA NA Harris and six others with burn injuries. The blast reported at around 8:30 pm during a cultural programme gripped the central parts of Bengaluru in a panic especially after the incident of police recovering a live bomb in Mangaluru airport. 

According to sources in Shanthinagar, MLA Harris was attending the birthday celebrations of MGR organized by the locals close to his residence in Shanthinagar. Following the blast, Harris and a few others who standing close to the MLA sustained burn injuries and rushed to the nearby Philomena Hospital immediately and police officials from both the Ashok Nagar and Vivek Nagar visited the spot. The police officials are yet to confirm whether it was a bomb blast or due to the bursting of loud and powerful crackers. 

Chethan Singh Rathore, DCP (Central) visited the hospital and the blast site. A team of forensic science lab experts have also been summoned to the spot to collect samples for ascertaining the nature of the blast. MLA Harris’s son Mohammed Nalapad who rushed to the hospital along with supporters told media persons that they are completely shocked by the incident. 

“He was sitting on a chair and suddenly something that was hurled at him exploded beneath the chair. He sustained injuries to his leg and brought to the hospital. He is being treated by a team of doctors and other injured supporters are also being attended to by the doctors,” Nalapad said. 

Expressing shock over the incident, he said, “My father has been an MLA for 12-years and nothing of this sort had happened before in the constituency. We have no rivals and my father never had any gunmen. We are all shocked and have complained to the jurisdictional police.” 

Meantime, Dr Shankar Prasad, Medical Director, St Philomena’s Hospital explained that Harris and others are currently being treated for minor injuries. “None of them have any open cut injuries and they are being examined further,” Dr Prasad told DH. 

According to Dr Prasad, Harris had a minor blood clot in his left leg which was possibly due to a hard object hitting him during the blast. “We have taken X-Ray and examining further. At the look of it, it seems like a very minor injury,” he added.
