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.

Alappuzha, Jan 9: The houseboat of Nobel Laureate Michael Levitt was blocked in the backwaters here for some time by trade union activists, who were on a nationwide strike against the Centre's "anti-labour" policies on Wednesday.

Michael Levitt, an American-British-Israeli biophysicist and a professor of structural biology at the Stanford University in the United States, said the incident sent a bad message to tourists.

Levitt, who was in Kerala as a state guest, also said he felt as if a bandit had stopped his wife and him at gunpoint. Police said Levitt, who received the 2013 Nobel Prize in Chemistry, was in Alappuzha with his wife and they were stopped by the protesters near Kainakary.

"Being stopped by criminals on the backwaters sends a very bad message to tourists. It is as if a bandit stopped us at gunpoint and delayed us under the threat of force for one hour," Levitt wrote in an email to his tour agent at Kottayam.

In the email, which was later released to the media, he also said the person who blocked them "ignored all arguments that tourists were exempted" from the strike.

"This person, who did this, ignored all arguments that tourists were exempted and that I am a VIP guest of the Kerala government. He was obviously acting, knowing that he was safe from prosecution. Sadly, this makes me fear that India is sinking into lawlessness," Levitt wrote in the email.

The police registered a case after the houseboat owners filed a complaint in this regard.

Reacting to the incident, state Tourism Minister Kadakampally Surendran said the government would take strong action. "Strong action will be taken against those anti-social elements who stopped the boat. Levitt was here as a guest of the state government. The government had made it clear that the tourism industry was exempted from the strike," he said.

Trade union leaders had also announced that the strike would not affect the tourism industry.

Ten trade unions, including the INTUC, the AITUC and the CITU, had called for the nationwide strike to protest against the labour reforms, FDI, disinvestment, corporatisation and privatisation policies of the Centre and press for a 12-point demands of the working class, relating to minimum wage, among others.
