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, Mar 28: Karnataka Pradesh Congress Committee (KPCC) chief DK Shivakumar on Saturday appealed to the authorities to arrange transport for migrant workers, stating that it is appalling to see their plight as they are walking hundreds of kilometres to their villages amid COVID-19 lockdown.
"Appalling to see the plight of poor migrant workers who are walking hundreds of kms to their villages. We cannot abandon our citizens, especially children, and put them at risk. Appealing to the authorities to arrange transport. Please take sufficient safety precautions as well," Shivakumar tweeted.
Hundreds of people, comprising mostly of migrant workers and their families, gathered at the Lal Kua in Uttar Pradesh from Delhi, Gurugram and other places, to take buses to their respective destinations amid the lockdown.
While the Prime Minister Narendra Modi had imposed a nationwide lockdown to prevent the spread of coronavirus, the Uttar Pradesh administration had decided to ply these buses to help thousands of migrant workers who were stuck in the national capital and had started returning on foot to their native places in Bihar, Uttar Pradesh, among others.

Kasaragod, Apr 17: Even as this district continue to remain in the high-alert red zone category of Covid-19, Kasaragod has slowly but steadily been limping back to restraint level of the pandemic from a possible slipping into a stage-3 of community spread early this month.

Thanks to the stringent and committed measures implemented by the district administration crisscross the district besides total isolation of few localities by enforcing triple lockdown.

The district had been a Covid-19 hotspot ever since an NRI who returned from the Gulf violated quarantine protocol and travelled wide and far by meeting and contacting with several people including two MLAs of the district. That apart the irresponsible attitude of the people who broke the rules of quarantine and lockdown norms also made things go from bad to worse resulting in contributing for a near-half of the total positive cases in the state at the beginning of April.

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.
