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 7: Slogans of ‘Inquilab Zindabad’ rent the air at Town Hall on Monday evening as thousands of students, social activists, lawyers, doctors and theatrepersons among others staged a protest to denounce Sunday’s attack on the students and faculty of New Delhi’s Jawaharlal Nehru University (JNU).

“This is unacceptable. As students living in hostels, we are now worried about our safety,” said Prakruthi Kishore, a student of National Law School of India University (NLSIU), Bengaluru.

Rishi Kumar, a student of Indian Institute of Science, pitched in. “JNU is an extremely protected university located in the national capital. It’s surprising that such an incident occurred amid tight security.”

Delhi police and the government need to wake up and take stringent action against the goons, Kumar said, adding: “Students can’t be treated like puppets. The government needs to act immediately.”

“The government is behaving shamelessly by sending goons to threaten students and professors of JNU,” said Alokanath Pandit, a lawyer.

With “Zor se bolo-azadi, tum din me maaro-azadi, hum raat me ayenge-azadi,” drowning the cacophony of traffic at the intersection, the sloganeering reached a crescendo around 6pm as the protesters raised their hands in a show of solidarity with the beleaguered JNU community.

Theatrepersons Prasanna and Arundathi Nag, farmer leader Kodihalli Chandrashekar and social activists Tara Krishnaswamy and Srinivas Alavilli were present at the protest venue. “It is not fair that educational institutions are now becoming the target. First, they hiked fees and now they are attacking students. What is the government doing,” Arundathi asked.

“JNU has always been an institution which has raised its voice against atrocities across the country as its students harbour no fear. This is an alarm bell for the country and the government to wake up. Students are the future and can’t be targeted,” she added.

Chandrashekar said Narendra Modi is unfit to be the Prime Minister as he doesn’t keep his word. “Modi said he will help farmers but has done nothing for them. He said he will provide employment to students but is now making them furious,” he said.

New Delhi, Jan 30: A terrorist opened fire at people peacefully protesting against the contentious citizenship amendment act (CAA) near the Jamia Millia Islamia University in Delhi this afternoon, causing chaos and panic in the area.

One person has been injured. In a video, the terrorist, wearing a black jacket and a pair of white trousers, can be seen walking on a road, waving a gun as he shouts "who wants Azadi, come I'll shoot you. Then he says, "Yeh lo aazadi (here's your freedom)" and opens fire injuring a student in front of police.

A video of the attack that is being shared widely on social media also showed the assailant also shouting the 'Jai Shri Ram' slogan and warning protesters to chant 'Vande Mataram' if they want to stay in India. The injured student, Shadab, was hit by the bullet in his arm and has been admitted to the Holy Family hospital in Jamia Nagar.

His condition is stated to be stable. The incident took place near the hospital when a protest march was being taken out by students. Students said that the attacker tried to hijack the peaceful protest and threatened the anti-CAA agitators.

The shooting comes in the aftermath of communally charged, hateful and violence provoking rhetoric by several BJP leaders in the run-up to the assembly elections in Delhi.

Junior finance minister Anurag Thakur had on Monday led chants of ‘shoot the traitors’ at a poll rally in north Delhi’s Rithala. The minister prompted "desh ke gaddaron ko..." to which the crowd responded "...goli maaro sa***n ko". The chant translates to "shoot down the traitors who betray the country". Protesters against the CAA and the NRC have often been dubbed anti-national by members of the ruling BJP.

After Thakur’s hate speech, a man carrying a gun was also caught at Delhi's Shaheen Bagh, the venue of mega protests. The man had walked into the protest ground and allegedly brandished the weapon till he was overpowered by the surrounding protesters, eyewitnesses said.

Mangaluru, May 27: Mangaluru MLA U T Khader today urged Dakshina Kannada MP and Karnataka BJP chief Nalin Kumar Kateel to pave the way for immediate repatriation of Mangalureans stranded across Gulf countries.

The development comes amidst reports that lack of preparedness on part of the authorities concerned in Dakshina Kannada compelled the Centre to delay the operation of repatriation flights from various Gulf to Mangaluru International Airport under Vande Bharat Mission.

Lakhs of people from Mangaluru region (coastal Karnataka) alone are working in middle eastern countries like Saudi Arabia, United Arab Emirates, Kuwait, Bahrain and Qatar. Thousands of them are currently stranded thanks to covid-19 lockdown and are helplessly waiting for repatriation.

Speaking to coastaldigest.com, Mr Khader said he already spoke to Mr Kateel and brought to his notice the plight of Mangalureans in Saudi Arabia and other gulf countries. "There are a large number of pregnant women, senior citizens and patients who need immediate repatriation. It is the responsibility of the elected representatives and district administration to pave the way for the repatriation of our people and arrange quarantine facilities for them," he said. 

"Mr Kaeel is not only MP of Dakshina Kannada. He is also the chief of Karnataka's ruling party. Hence, he must play a crucial role in facilitating the return of Kannadigas in general and Mangalureans in particular," Mr Khader said.
