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 2: The Congress leadership in Delhi is expected to start the process of selecting a new party chief for Karnataka next week. There are strong indications the race has narrowed to DK Shivakumar and MB Patil.

Party insiders said the leadership almost finalised Shivakumar’s name as the president of Karnataka Pradesh Congress Committee (KPCC), but the decision was put on hold after requests by some senior members.

“It’s not that we are against Shivakumar. We think the party should have a Lingayat at the helm since community strongman and chief minister BS Yediyurappa is at the fag end of his long political career. There’s an opportunity here for a Congressman to occupy that space,” said a senior Congress politician, who didn’t want to be named.

That’s where the candidacy of Patil, a Lingayat, scores high.

The party, however, doesn’t want to compromise on quality and wants an efficient KPCC president who can unite two rival factions within the party, one led by Siddaramaiah and another by former union minister KH Muniyappa.

The need to pick a new state president arose after Dinesh Gundurao resigned from the post last month, taking moral responsibility for Congress’s poor showing in the byelections. Siddaramaiah also stood down as Congress party legislature leader.

The insiders said the new KPCC chief could be announced after January 16. The party might also appoint two working presidents and a new legislature party leader, who will automatically become the opposition’s voice in the assembly.

For the latter position, the name of senior Dalit politician and former deputy chief minister G Parameshwara is doing the rounds. But the party, the sources said, could still ask Siddaramaiah to reconsider his decision and stay on.

Many Congress members had raised questions over his stewardship after the bypoll disappointment. They said on his watch, the party had also fared badly in the assembly and Lok Sabha elections, demanding that he be held accountable.

Siddaramaiah is expected to visit Delhi next week to discuss the leadership issue with party boss Sonia Gandhi. Some other senior Congress members, including BK Hariprasad, are also likely to meet her.
