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.

The Central Board of Secondary Education (CBSE) has rationalised by up to 30 per cent the syllabus for classes 9 to 12 for the academic year 2020-21 to reduce course load on students amid the COVID-19 crisis, Union HRD Minister Ramesh Pokhriyal 'Nishank' announced on Tuesday.

The curriculum has been rationalised while retaining the core elements, the Human Resource Development said.

Among the chapters dropped after the rationalisation exercise are lessons on democracy and diversity, demonetisation, nationalism, secularism, India's relations with its neighbours and growth of local governments in India, among others.

"Looking at the extraordinary situation prevailing in the country and the world, CBSE was advised to revise the curriculum and reduce course load for the students of classes 9 to 12.

"To aid the decision, a few weeks back I also invited suggestions from all educationists on the reduction of syllabus for students and I am glad to share that we received more than 1.5K suggestions. Thank you, everyone, for the overwhelming response," Nishank tweeted.

"Considering the importance of learning achievement, it has been decided to rationalise syllabus up to 30 per cent by retaining the core concepts," he added.

The Union minister said the changes made in the syllabi have been finalised by the respective course committees with the approval of the curriculum committee and the Governing Body of the Board.

"The heads of schools and teachers have been advised by the board to ensure that the topics that have been reduced are also explained to the students to the extent required to connect different topics. However, the reduced syllabus will not be part of the topics for internal assessment and year-end board examination.

"Alternative academic calendar and inputs from the NCERT on transacting the curriculum using different strategies shall also be part of the teaching pedagogy in the affiliated schools," a senior official of the HRD ministry said.

For classes 1 to 8, the National Council of Education Research and Training (NCERT) has already notified an alternative calendar and learning outcomes.

According to the updated curriculum, among the chapters deleted from class 10 syllabus are-- democracy and diversity, gender, religion and caste, popular struggles and movement, challenges to democracy

For class 11, the deleted portions included chapters on federalism, citizenship, nationalism, secularism, growth of local governments in India.

Similarly, class 12 students will not be required to study chapters on India's relations with its neighbours, changing nature of India's economic development, social movements in India and demonetisation, among others.

Universities and schools across the country have been closed since March 16 when the central government announced a nationwide classroom shutdown as one of the measures to contain the COVID-19 outbreak.

A nationwide lockdown was announced on March 24, which came into effect the next day. While the government has eased several restrictions, schools and colleges continue to remain closed.

Bengaluru, Jul 7: There seems no impact of Covid-19 on kharif crop sowing in Karnataka with the current year actually being ahead of previous years, according to an official here on Monday.

"In agriculture, as far as sowing is concerned, there is no impact of COVID-19," Agriculture Commissioner Brijesh Kumar Dikshit told IANS. One of the reasons, according to Dikshit, is that people in rural areas are aware, but not scared of the pandemic.

"In rural India, coronavirus is there. People are aware, not scared. They are taking precautions, but don't have any phobia," he said.

Another reason was that by June the number of infections in Karnataka was not as high as other states, when a lot of sowing was done, he said.

By the end of June, Karnataka saw 15,242 Covid-19 cases. Of that, 7,074 were active.

The sowing is ahead of previous year as it's mostly dependent on weather. "It's ahead of previous years. Agriculture is directed by weather and rains had been slightly earlier this year," he said.

According to Karnataka State Natural Disaster Monitoring Centre, at 185 mm the state received 14 mm less rain in June against the normal 199 mm. "It's like a normal year, or slightly a good year," he said.

Some crops will be sown in the last fortnight of July and few more will extend up to August 15. "The last two weeks will be critical and on July 31 we should be able to tell whether we are short or ahead," he said.

According to preliminary indications, the Commissioner said the area under agriculture is increasing this year, which could also be because that labourers might have come back.

Bengaluru, May 29: Chief Minister B S Yediyurappa and BJP State President Nalin Kumar Kateel will resolve any differences of opinion among party leaders in Karnataka, according to Minister of State for Railways Suresh Angadi

If anybody has any issues, they should get them resolved by talking with Yediyurappa and Kateel. Internal matters, if any, should not be discussed in public, he said.

Angadi told reporters here on Friday that differences of opinion among party leaders have not come to his notice. A section of party leaders assembling for dinner should not be constituted as a meeting of dissidents. BJP has internal democracy and any differences of opinion if exist will be resolved at the party forum.

He added that if MLA Umesh Katti has any issues regarding cabinet berth or regarding assurances given to him by Yediyurappa during the Lok Sabha elections, he should talk with the chief minister.

Everyone in politics has aspirations and it's natural. Those aspiring for the upcoming Rajya Sabha elections should talk with the chief minister or the state president, he said.

Ramesh Katti was former MP and there was nothing wrong in him being aspirant for Rajya Sabha elections, he said.

Angadi said, "Party is supreme. We shall work for the victory of party candidates irrespective of who they were".

A state cabinet meeting was held on Thursday. Many of the MLAs too had been to Bengaluru for constituency-related works. As they had been meeting after a long time, all gathered for dinner, he expressed.
