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 22: President Ram Nath Kovind on Saturday said an ideal trade-off needs to be reached between new media -- which is fast and popular -- and traditional media which has developed skills to authenticate a news report, which is a costly operation.

Addressing the fourth edition of ‘the Huddle’ – the annual thought conclave of the Hindu here, he asserted that the internet and social media had democratised journalism and revitalised democracy, but had also led to many anxieties.

While the new media was fast and popular and people could choose what they wanted to watch, hear or read, traditional media would have to introspect on its role in society and find ways to earn the reader’s full trust again as "the project of democracy was incomplete without informed citizens – which means, without unbiased journalism."

Debate and discussion were internalised in India’s social psyche to arrive at truth since time immemorial, he said.

"There is no doubt that perception of truth is conditioned by circumstances. The conditions that cloud the truth’s positions are effectively dispelled by a contestation of ideas through debate, discussion and scientific temper. Prejudices and violence vitiate the search for truth."

Expressing happiness to attend ‘The Huddle’ organised by The Hindu, he said the Hindu group of publications had been relentlessly aiming to capture the essence of this great country through its responsible and ethical journalism. He commended them for their insistence on sticking to the five basic principles of journalism – truth-telling, freedom and independence, justice, humaneness and contributing to the social good, an official release here said.

Mr Kovind said dogmas and personal prejudices distorted the truth. In the 150th year of Gandhiji’s birth, he asked all to ponder over this question: "will it not be proper to pursue truth itself as the ideology? Gandhiji has shown us the path by walking ceaselessly in search of truth which would ultimately encompass every positive attribute that enriches the universe."

Mysuru, Jan 27: Chief minister BS Yediyurappa on Sunday refused to field questions on the state’s finances, merely saying his budget on March 5 will do the talking. The question came in the wake of Siddaramaiah, leader of the opposition, claiming recently that the state’s coffers were dry and its finances were in the doldrums.

However, Yediyurappa insisted the state’s finances were sound and it will be better once promises made by the business community during his trip to Davos turn into concrete investment.

“I will present the budget for 2020-21 on March 5. People will then know about the state’s financial position,” Yediyurappa said during a visit to Suttur Mutt on Sunday. “I will answer Siddaramaiah’s comments during the forthcoming budget session of the state legislature. The Davos meet I attended will benefit the state immensely. It will bring huge investments that will promote industry and agriculture growth and various job-generation activities.”

Bengaluru, Jan 17: Six persons, said to be supporters of Social Democratic Party of India, have been arrested in connection alleged attempt to murder a member of RSS in Bengaluru.

Varun Bhopala (34), a resident of Sarakki in JP Nagar, was attacked while he was on his way to his father's shop near JC Road after attending a pro-CAA event organised by the RSS and other Hindutva organisations on December 22, 2019.

Police commissioner Bhaskar Rao said the arrested are Irfan alias Mohammed Irfan (33), Syed Akbar alias Mechanic Akbar (46), Syed Siddiq Akbar (30), Akbar Basha (27), Sanaulla Sharif (28) and Sadiq UL Ameen (39) - all residents of KG Halli in East and North Bengaluru.

Rao said the arrested wanted to attack and kill the leaders who took part in the pro-CAA event. They initially pelted seven stones to scatter the crowd so that they can attack the leaders, but they failed. Later, they saw Varun walking out of the crowd wearing a saffron shirt. So the arrested followed him and attacked him with lethal weapons. Assuming he is dead, the gang fled on their bikes towards Bidadi.

''The SDPI activists were funded by their leaders to create a disturbance, kill Hindu organisation leaders,'' Rao said. "I have formed a special team to investigate in-depth about the SDPI activities and take necessary action,'' he added.
