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, Jan 5: B S Yediyurappa-led Karnataka cabinet has finally decided to resume supply of subsidised rice and wheat to students of welfare institutions and hostels including those run by religious mutts under the Dasoha Scheme’s welfare programme. The supply was stopped over two months ago.

“Cabinet has decided to continue supply of subsidised foodgrains (rice and wheat) for the benefit of 37,700 children under the Dasoha scheme in 351 welfare institutions for the next one year at the cost of Rs 18 crore,” said J C Madhuswamy, Law and Parliamentary Affairs Minister. Under this scheme, institutions that provide free accommodation and food for students are entitled to avail 10 kg rice and 5 kg wheat per student every month at subsidised rates. But following a central government directive in November, the state government had stopped supply to private institutions since December.

Hours before the cabinet meeting, Khader addressed a press conference and said, “This government is snatching away food from children by stalling the supply of foodgrains. Institutions like Suttur Mutt, Siddaganga Mutt that have worldwide fame for their service are being inconvenienced by this,” Khader said.

Finding itself in a fix, especially in a matter that involves mutts, the cabinet was quick to restore the supply. “Foodgrains were being supplied to 183 government-run institutions and 281 institutions run by private entities. As per a central government directive, supply to private institutions was stopped but the decision was made by the previous government,” Shashikala Jolle, Women and Child Development Minister, said.

Bengaluru, May 28: A thousand government schools in Karnataka are set to get Englishmedium sections from this academic year (2020-21). These institutions will function in both English and Kannada medium.

The decision was taken by primary and secondary education minister S Suresh Kumar and officials of the education department at a meeting on Wednesday.

Suresh Kumar said dualmedium will help improve the standard of schools and enable their development. The poorest of the poor spend almost 40% of their income on their children’s education in private schools. With the introduction of dual-medium, the government hopes such families will be able to save their earnings, he said. These schools will impart lessons in both English and Kannada. They will also provide textbooks in both languages.

‘Kannada must for all’

The meeting reviewed implementation of the compulsory Kannada Language Learning Act, 2015. Officials from the Kannada Development Authority were present at the meeting who claimed that some private schools have failed to implement the Act properly.

“Action will be taken against such institutions. Every child studying in schools across the state must learn Kannada,” Kumar said at the meeting.
