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, Apr 12: Former chief minister H D Kumaraswamy on Sunday appealed to the Central government to announce the rent rebate scheme for the benefit of tenants in the wake of economic activities coming to a grinding halt due to COVID-19 related lockdown.

In a series of tweets, Kumaraswamy said people are facing difficulty in paying rent as usual and hence the rent rebate scheme should be initiated.

"Many countries have already announced rent rebate scheme for tenants during COVID19 emergency. It is surprising that Indian Govt has not announced any such relief even to residential tenants. I urge the PM to immediately come to the rescue of everyone living in rented housing," Kumaraswamy tweeted.

He said a considerable workforce and students in metropolitan cities live in hostels and rented houses.

As all economic activity has come to a grinding halt, it is very difficult for them to pay the rent as usual.

The Prime Minister must announce rent rebate scheme, he added.

Highlighting the plight of the tenants, Kumaraswamy said, "If the landlords insist on rent, the tenants cannot even go searching for new accommodation due to the emergency. Hence the government intervention is essential. The PM must announce a comprehensive national rent rebate scheme for COVID-19 emergency."

Bengaluru, Jan 24: The JD(S) is looking to leverage anti-Citizen (Amendment) Act (CAA), National Register of Citizens (NRC) and National Population Register (NPR) sentiment sweeping the country to revive itself and will hold protests in Bengaluru and New Delhi.

The Bengaluru protest is scheduled for Friday. At a meeting of party workers in Bengaluru on Thursday, party patriarch HD Deve Gowda and former chief minister HD Kumaraswamy urged the rank and file to participate in the rally to send out a loud and clear message to the BJP.

"The BJP has set out to make Muslims second-grade citizens. India has 40 crore Muslims, can these communal forces eliminate them all?" Gowda said in his address. "We should have the guts to launch a massive protest at Jantar Mantar. We should be prepared to go to jail in the fight against [Prime Minister] Narendra Modi and [Union home minister] Amit Shah."

Gowda said he will lead the rally in Delhi and urged secular parties to unite to take on the BJP. "It is important that regional parties, which share a secular ideology, unite on a common agenda and fight the BJP. Bihar, Kerala and Odisha have said they will not implement CAA. The sentiment is likely to spread to other states," Gowda said.

Kumaraswamy said not only Muslims but many other communities will also bear the brunt of BJP’s "divisive politics". "This pair of Hakka-Bukka [Modi and Shah] is not targeting Muslims alone," he said. "For them, all communities other than upper caste Hindus are inferior Shudras. They will treat even Lingayats, Vokkaligas and Dalits with the same contempt."

The former CM made a special appeal to Lingayats, who generally back the BJP, to stop supporting the saffron party’s caste-oriented politics. "You had appreciated my farm loan waiver scheme and promised support in the elections. But, the results were contrary to that," he said.

The JD(S) passed three resolutions including one to condemn the Centre for enacting CAA. The others were to protest against the Centre’s indifference to the floods in the state and the failed economic policy of the Centre.

Bengaluru, July 20: The Karnataka government has reiterated that no final decision has so far been taken on reopening of schools in the state.

The clarification comes after minutes of the July 15 HRD ministry meeting where Karnataka education department officials said schools are reopening on September 1 went viral on social media. 

“The state government has not decided yet on starting schools. That they will reopen in September was only a general opinion expressed by our officials at the meeting. At present, we have no plans to start schools unless there is a conducive environment. There’s no need for anxiety,” said primary and secondary minister S Suresh Kumar.

Kumar said the government is involved in meeting the education sector’s changed priorities in the current scenario.

The minutes were of a virtual conference on school-safety plans, with representatives of state governments and Union territories expressing views on reopening of schools. 

Against the name of Karnataka, “After September 1” was written. Similar datelines were given by Kerala, Ladakh, Manipur, Rajasthan, Odisha and Andhra Pradesh, while in case of many other states it said “no decision”.

An education department official said Karnataka submitted to MHRD that it will be able to take a decision only after September 1, depending on the situation in the state.
