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, Jan 6: JD(S) leader H D Kumaraswamy on Monday said he would not get involved in any 'wicked act' of bringing down the B S Yediyurappa-led government in Karnataka, amid claims that 15 to 20 BJP MLAs were ready to come out.

Clarifying that he would not disturb the government, the former Chief Minister said for him, the development of the state was important. "With great difficulty, you (Yediyurappa) have become Chief Minister for the fourth time, (I am) happy, I have nowhere said that I will disturb your government. Even now some people come and ask why I'm sitting silent when 15-20 people are ready to come out of BJP and why don't I make an attempt (to poach them), Kumaraswamy said. Speaking to reporters in Hassan, he sought to know why he should get entangled in that 'sludge' and he was not in a hurry.

"I will not get involved in a wicked act of removing a responsible government like Yediyurappa did. For me the development of the state is important," he said.

Though Kumaraswamy had raised questions about the longevity of the BJP government ahead of the December 5 bypolls, he had even then given clear indications that he would not attempt to pull down the administration as it would affect the development of the state.

The ruling BJP had swept the by-elections by winning 12 of the total 15 seats, helping the Yediyurappa government retain the majority in the Assembly.

With BJP winning 12 of the 15 assembly constituencies, it's numbers went up from 105 (including an independent) to 117, which is well ahead of the halfway mark of 111 in a 223-member Assembly (two seats-- Maski and R R Nagar-- are vacant due to pending litigation in the High Court).

The BJP came to power after the Kumaraswamy-led Congress-JD(S) coalition government collapsed as 17 MLAs had rebelled against the alliance leadership and resigned as legislators, to later favour the saffron party.

Bengaluru, Apr 15: The Opposition Congress in Karnataka on Wednesday accused the BJP government, headed by Chief Minister B S Yediyurappa, of showing discrimination in distribution of relief material to those affected by the lockdown, clamped to check the spread of Novel Coronavirus, by favouring constituencies represented by the ruling BJP Legislators.

Despite that, the party intends to extend full cooperation to the government during this hour of crisis without indulging in politics, it urged the administration to be “transparent”.

''We have had our (Congress) Task Force meeting today, during which we discussed several matters. There is a lot of difference between the government's talk and its deeds,'' KPCC President D K Shivakumar said.
