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.

The students who are pursuing UG and PG courses at mid semester levels will be evaluated internally based on their academic performance along with the marks scored during the previous semester or year.

"Based on this comprehensive evaluation, we will promote the students to next semester. But for the first semester students, they will be promoted entirely based on internal evaluation on academic performance," the Deputy Chief Minister explained.
