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, Feb 19: Congress MLA UT Khader on Wednesday slammed the Central government over the enactment of the Citizenship (Amendment) Act and said it violates the Constitution.

"The new citizenship amendment bill is unconstitutional. The citizenship cannot be given on cast and creed basis. Because of these things we are fighting against it," he said while speaking to media in Bengaluru.

Opposition along with several non-BJP state governments, including Madhya Pradesh, West Bengal, Kerala, Punjab and Rajasthan have refused to implement the Citizenship Amendment Act (CAA) and the proposed NRC in their respective states.

The CAA grants citizenship to Hindu, Sikh, Jain, Parsi, Buddhist and Christian refugees from Pakistan, Afghanistan and Bangladesh, who came to India on or before December 31, 2014.

Bengaluru, Apr 11: Karnataka Library Department’s mobile application, which is said to be the first of its kind initiative in the country has seen an exponential growth in downloads during the COVID-19 lockdown, a senior Minister said on Friday. The main reason that the application is growing is due to the heavy students demand as schools and colleges are closed during the 21-day nationwide lockdown.

Students are relying on online material for their studies as they can’t step out of the house and risk being infected.

The Library Department's efforts to keep readers active through the lockdown time, by prompting them to utilise its e-initiatives is paying off, Primary and Secondary Education Minister Suresh Kumar said.

"The app is seeing exponential increase in downloads since its launch. As many as 16,500 people have taken it; while ten thousand people have downloaded it during this brief lock down time itself," he said.

E-library mobile app was released by the library department on February 26.

There are over one lakh e-books available on department's digital platform ranging from arts, humanity, school curriculum, competitive exams and self help to classic novels - all for free for the readers.

"Its needless to say, the variety of attractive content that is available in the app is creating all the buzz among the public. Not just the books, the app contains over 600 educational videos too," the Minister said in a statement.

Considering that over 16,500 readers have downloaded the app since its launch a couple of months back, its high time, we see this domain as an opportunity for growth, he said, and stressed on the need for better adaptability approaches to the changing times.

Mangaluru, Feb 25: Notorious gangster Ravi Poojary,

who has been extradited to India from Senegal, has 34 cases registered against him within the city police commissionerate.

Now in Bengaluru police custody for interrogation in connection with several cases there, Poojary faces cases relating to murder, murder attempt, extortion and threat calls in the city, police sources said.

Sources said the city police are trying to get Pujari for interrogation though it would take a while as the court has allowed Bengaluru police to keep him in custody for questioning and evidence taking for 15 days.

Most of the cases in the city against him, 28 of them, are in connection with threat calls.

He had allegedly made threat calls in 2015 to the then state ministers B Ramanath Rai and Abhayachandra Jain, demanding immediate arrest of the accused in the murder of Bajrang Dal worker Prashanth Poojary.

All the cases against Poojary in the city were registered between 2007 and 2018.

Cases involving murder, death threats and shootouts are among the cases to be investigated, the sources said.

A total of 28 cases of death threat calls, one of murder, three of shootouts, one of abduction and a case of funding his associates lodged in prison are the crimes being probed by the city police.

The cases are now pending in courts at different stages of trial.

Cases of making threat calls to businessmen using his associates demanding protection money have been registered at Moodbidri, Kavoor, Kadri, Konaje, Barke and Urwa police stations.

Some of his associates were imprisoned in 2012 in connection with threat calls to a businessman from Kinnigoli.

The case relating to providing them money while in prison was also registered in the same year.

Pujari, wanted in many cases including extortion and murder in different parts of the country, including Karnataka and who had been on the run for over 15 years, was deported to Senegal following his arrest and later extradited

He had jumped bail in Senegal last year after being arrested there.
