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.

Apr 9: A panel of experts in the Karnataka state has suggested that the ongoing lockdown should be continued in districts identified as Covid-19 hotspots, including Bengaluru, to limit the spread of the pandemic.

IT companies and government offices providing essential services should be allowed to function with 50% staff, according to the committee headed by Narayana Health chairman Dr Devi Shetty, which submitted its report to chief minister BS Yediyurappa on Wednesday.

It has also asked the government to ease restrictions gradually and take adequate care over the next six months to contain the outbreak. The committee urged the government not to permit AC buses and metro services till April 30 and allow private vehicles only on alternate days (even-odd number-wise) for two weeks after April 15.

The government must close schools and colleges till May 31 and allow only inter-state movement of goods transport. The government could allow non-AC shops to open. It has suggested that the ban on inter-state train and flight services should continue.

Education minister S Suresh Kumar, who is the state Covid-19 spokesperson, said the Cabinet, which is meeting on Thursday, may discuss the recommendations and take a view on de-escalation of the lockdown.

Prime Minister Narendra Modi will interact with chief ministers through videoconference on April 11, after which the government will get an idea about the Centre’s thinking, he said.

While some states including Kerala, Maharashtra and Telangana have favoured continuation of the lockdown, Yediyurappa has not taken any stand publicly and has instead been implementing the Centre’s decision.

Six new cases

Karnataka on Wednesday reported six new Covid-19 positive cases, including that of a 65-year-old person in Kalaburagi, who died due to severe acute respiratory infection.

The health authorities have issued a notice to the private hospital -- where the deceased was initially admitted before being taken to a government hospital -- for not reporting the case to the government. The government has locked down the hospital, kept its entire medical team under quarantine, and police have registered a case of criminal negligence against the hospital authorities.

Of the other five positive cases, two had a travel history to Delhi, one had contact with a Dubai returnee and two others had close contacts with infected people.

This takes the total number of positive cases in the state to 181. Five people have died, while 28 have been discharged so far.
