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.

Kalaburagi, Feb 20: All India Majlis-e-Ittehadul Muslimeen (AIMIM) leader Waris Pathan on Wednesday said that 15 crore Muslims can dominate 100 crore Hindus.

"The time has now come for us to unite and achieve freedom. Remember we are 15 crore but can dominate over 100 crores," said Pathan while addressing an anti-CAA rally here.

"They tell us that we have kept our women in the front - only the lionesses have come out and you are already sweating. You can understand what would happen if all of us come together," he said.

The CAA grants citizenship to Hindu, Sikh, Jain, Parsi, Buddhist, and Christian refugees from Pakistan, Afghanistan, and Bangladesh, who came to India on or before December 31, 2014.

Protests have erupted across the country against the Citizenship Amendment Act (CAA), the National Register of Citizens (NRC) and the National Population Register (NPR).

Karnataka on Saturday reported 12 new cases, the highest in a single day so far, taking the tally in the state to 76.

Late at night, the Mysuru district commissioner said five more people had tested positive in the district. But it was yet to be confirmed by the state health department.

Of the cases, 41 are from Bengaluru, eight from Chikkaballapur, while Uttara Kannada and Dakshina Kannada districts have seven each.

Interestingly, the highest number of patients are those from Dubai or those who had transit travel via Dubai. Out of 76 cases, 17 cases (22%) have travel history to Dubai, the capital of Emirate of Dubai and the most populous city in the United Arab Emirates (UAE).

Medical Education Minister Dr K Sudhakar, who is also in-charge of COVID-19 operations, said that Dubai has been a major concern as far as Karnataka COVID-19 patients are concerned. “Most of the positive cases have come through Dubai suggesting something amiss there,” he said. 

Echoing the same, Dr Prakash Kumar, Joint Director, Communicable Diseases, Department of Health and Family Welfare, said, “The layover in Dubai is around six to seven hours. We are seeing Dubai to be the new epicentre of the virus as far as India is concerned.”

UAE was initially not on the list of countries from where passengers were screened. It was added much later when clusters of patients with travel history to Dubai began popping up all over the country.

Patient-19 has infected the maximum so far.

Out of the 12 cases that tested positive on Saturday, five are contacts of Patient 19. All of them are being treated at a Chikkaballapur hospital. Two of them are from Hindupur, Andhra Pradesh, and three are residents of Gauribidanur taluk in Chikkabalapur district.

P19, a 31-year-old man from Chikkaballapur, had travelled to Mecca, Saudi Arabia, and returned to India on March 14. Existing patient clusters suggest that P19 had infected the maximum number of people. Officials did not reveal how many people he originally travelled with to Mecca.

Amid the rise in cases, Jawaid Akhtar, Additional Chief Secretary (Health), maintained that the state had not reached stage 3. But he had no definitive answer as to how the Mysuru patient contracted the virus despite health officials he was in touch with not testing positive.

Health Commissioner Pankaj Kumar Pandey said around 1,000 primary contacts of all positive cases have been classified as high-risk and low-risk. The high-risk patients are in government hospitals while the low-risk ones in quarantine facilities.
