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.

Thiruvananthapuram, Dec 4: Depressed over the communal and racist policies of union government, a 67-year-old retired school headmaster committed suicide allegedly after losing matriculation certificates and documents related to his father.

The victim was identified as Mohammed Ali a resident of Narikunni in Kozhikode district in north Kerala.

On finding Ali missing from home on Friday morning, his family members conducted a search in the nearby areas. His body was later found in a well located in one of his relative’s compound nearby.

A suicide note recovered, suspected to have been written by the victim read, “I have lost all my important certificates. Matriculation certificates of me and my wife. Old documents of my father are also missing. I think all these documents were given away along with the waste recently. None should be held responsible for my foolish act. You may get into trouble.”

According to relatives, Ali was under severe stress after regularly watching programmes related to CAA. He was also actively involved in anti CAA campaign.

“He was worried about the documents and had serious apprehensions about future,” said his younger brother Abdul Nasser.

“After attending an anti CAA meeting in Kozhikode he had shared his apprehensions. He used to frequently discuss the topic with others ,” recollected Jaffer a local resident.

Ali also had health complications. Meanwhile, the local police said that preliminary investigations suggested that the man could have taken the extreme step after losing documents. However, the reason behind the suicide could be said conclusively after detailed probe.

Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

The move came after the CBI received an approval from the Karnataka government to proceed with investigation into alleged role of 1998-batch IPS officer Nimbalkar and 2008-batch IPS officer Hilori, they said.

Along with the two officers, the agency has also named the company IMA, its founder Mansoor Khan and others in the case.
