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.

Mangaluru, Apr 16: An old refrigerator has been turned into a "disinfection chamber" by researchers who are striving to come up with solutions to tackle the spread of coronavirus.

Dr Arun M Isloor, head of Chemistry Department, National Institute of Technology Karnataka (NITK), Surathkal, along with research scholar Syed Ibrahim has come up with the device which can disinfect items kept inside it.

"We have named this as ZERO-COV," Dr Isloor said.

He says the device ensures 99.9 per cent destruction of microorganisms present on the surface of items.

"We can keep items like vegetables, currency notes, books or envelopes inside the chamber. Switching on the chamber for 15 minutes ensures 99.9 per cent destruction of microorganisms present in the surface of the items," Dr Isloor added.

Bengaluru, Jan 2: Prime Minister Narendra Modi on Thursday slammed states, which have not enrolled with the Pradhan Mantri Kisan Samman Yojana (PMKSY), saying that such petty politics has done great damage to the farming community.

"I expect that in the new year, those states which are not associated with the Kisan Samman Yojana will at least become a part of it this year," the Prime Minister said at a function in Tumakuru where he disbursed Rs 12,000 crore to six crore beneficiaries under the government scheme in one-go.

Also, he gave away the Krishi Karman Award to the selected farmers and distributed fishing equipment to the chosen ones on the occasion. Modi said political considerations by the state governments in implementing the PMKSY has caused severe loss to the poor farmers.

"Such politics has never strengthened the farmers. Our government understood your (farmers') needs, requirements and your aspirations and accordingly tried to implement the schemes," said Modi.

He further said his government never saw agriculture in fragments but in its totality. Claiming his government has ensured that the entire money reached the poor beneficiaries, Prime Minister hit out at the previous governments, when middlemen ruled the roost.

"There was a time when a rupee was rolled out (by the government) for the poor person, only 15 paise would reach him. The middlemen would pocket the remaining 85 paise. "Today, whatever money is dispatched from Delhi, the entire amount directly reaches the bank account of the beneficiary," he said.

He told the gathering about the various initiatives taken by his government to improve the agriculture sector such as completing the pending irrigation schemes, soil health card and 100 per cent neem-coating in urea.

Due to the initiatives of the government, agriculture production has gone up, he said. Speaking about measures in the fisheries sector, the Prime Minister said the sector has been promoted in the villages, financial help given to fishermen, modernisation of boats and building fisheries-related infrastructure have been done.
