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, Aug 3: All those who met Karnataka Chief Minister B S Yediyurappa, who has tested positive for Covid-19, in the last three-four days will have to be quarantined, Medical Education Minister Sudhakar K said on Monday.

He also said those who came in contact with Yediyurappa in a couple of programmes in the past week are being traced.

Sudhakar, a medical doctor himself, said Yediyurappa has "very mild cough and his chest is clear."

"I think eight to ten days," he told news agency when asked how long the Chief Minister would have to remain in hospital.

Sudhakar said he is also getting himself tested as a few of his office staff had tested positive.

"All those who met the Chief Minister in the last 3-4 days...ideally they should be quarantined till they receive their results/report. Those who came in contact with him in a couple of programmes will have to isolate themselves and subject themselves for testing," the Minister said.

On the Chief Minister meeting Governor Vajubhai Vala, along with Home Minister Basavaraj Bommai last Friday, Sudhakar said as a result "They also become primary contacts. Ideally, they should also be quarantined and tested."

Yediyurappa who was hospitalised on Sunday night after testing positive for Covid-19 was "doing well" and is "clinically stable", the hospital treating him said.

The 77-year old leader is being monitored by a team of doctors at the Manipal hospital here.

"He is doing well, is clinically stable and will be monitored closely by our team," the hospital said in a statement late last night.

"I have tested positive for coronavirus. Whilst I am fine, I am being hospitalised as a precaution on the recommendation of doctors. I request those who have come in contact with me recently to be observant and exercise self-quarantine," Yediyurappa had said in his tweet.

Yediyurappa was in home quarantine a couple of weeks ago, after some staff members in his home office were found infected with the virus. Subsequently, he tested negative for Covid-19.

New Delhi, Feb 28: They could hear shots being fired, sense smell of property and vehicles being burnt and feel the stones being pelted. Despite the mayhem that unfolded just a few steps away from their doorsteps, many Muslim households did not feel unsafe due to their Hindu neighbours during the violence in Delhi earlier this week.

Tarannum, a resident of Chand Bagh, said she cannot thank her neighbour Nem Singh enough for saving 15 members of her family that fateful night of February 25. Singh, an auto-rickshaw driver, lives right across her house.

"I could hear the thumping on the door. Our neighbour came to rescue us and assured us that no harm would come to our family, " said Tarannum who lives in lane number 7.

"We thought khayamat has come. Our kids too got scared. Those indulging in rioting are just terrorists. Hindu brothers gave us shelter and saved us. How should I say that they are Hindus or Muslims? When we were under attack, these Hindu brothers provided us safety. We should not fight, " said Tarannum while recounting the horror.

She said a mob has no face, no religion. "I want to tell everyone mob has no name, no religion. Kaun sa pathar kisne mara kisko laga pata hai kya? Pathar ne mazhab dekha kya? (Which stone was thrown by whom, who was hit, does anyone know. Stone does not have a religion," she said.

Singh said he could not bear the wailings of his neighbour's kids.

"Dar to tha par apni gali mein kisi ko pareshan nahi hone dena tha. (I too was afraid but I could not have let them hurt my neighbours)," said Singh when asked if he could have also been attacked for giving shelter to Tarannum family.

"I told them that the rioters will have to go through us first. We all were equally scared," recalled Singh.

Jameel, another local resident, said that his Hindu neighbours were even ready to sacrifice their lives to save him from the ruthless terrorists hired by pro-CAA politicians to unleash violence against Muslims.

Bengaluru/Kodagu, Feb 24: Three days after the sloganeering by 19-year-old college student Amulya Leona Norohna at an anti-CAA rally and her subsequent arrest on charges of sedition kicked up a storm, Karnataka minister BC Patil on Sunday advocated central legislation that enables authorities “to shoot at sight” those chanting pro-Pakistan slogans.

Responding to reporters’ queries on the ongoing fracas over the chants, Patil said he would appeal to Prime Minister Narendra Modi to bring in a law so that anti-national elements are “killed on the spot”.

“The Centre must promulgate a law that enables authorities to shoot those who do anything that is seen as anti-national and chant pro-Pakistan slogans,” Patil said. “These elements must be killed on the spot. I am appealing to the PM, through the media now, to bring in such a law. I will also write to the PM.”

In Kodagu, Union minister for chemicals and fertilizer, DV Sadananda Gowda, echoed state home minister home minister Basavaraj Bommai’s line that stringent action will be taken against those indulging in anti-national activity, saying there will be “no mercy” for those taking a pro-Pakistan stance.

“The Union government will assist in the police investigation in Amulya,” he said. Gowda went on to claim that many anti-national organizations have been using CAA protests for political gain.

“We will curb such incidents forever. We will not allow such incidents to happen in future. Organisers of such rallies should be thoroughly questioned,” Gowda said.

Bommai on Saturday had also claimed the government will initiate action against educational institutions and hostels it they fail to act against students indulging in such activity.

“The government will discuss ways to prevent such incidents in colleges and hostels. We will instruct heads of educational institutions and hostel wardens to initiate action against such students. If they fail, the government will take action against them,” Bommai said, without defining what constitutes anti-national activity.

However, despite Congress saying there is no room for anti-national activity and stringent action must be taken against those indulging in such activity, former minister and senior functionary DK Shivakumar suggested he found nothing in Amulya’s background to suggest she is anti-national.

“Let me make it absolutely clear that the Congress party will not support any person or persons who hail another country and bring shame to India,” Shivakumar said. “However, I have seen the girl’s [Amulya’s] previous posts on social media and read her statements on various forums. She has been making statements on an ideological ground. Let us not jump the gun, but investigate exactly what she meant to say.”
