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.

Hubballi, Feb 16: Rs 72,000 crore investment proposals were received at the Invest Karnataka meet, here on Friday, for the states northern region, said an official on Saturday.

"About 50 foreign and domestic firms have proposed to invest Rs 72,000 crore in the northwest and northern regions of the state and a dozen companies signed agreements with us," state Industries Department Secretary Gaurav Gupta said.

Rajesh Exports, Bengaluru-based group, signed an agreement to set up a manufacturing unit at Dharwad to rollout electric vehicles and make lithium ion batteries.

"Rajesh Exports proposes to invest about Rs 50,000 crore for manufacturing electric cars and lithium ion batteries for the domestic and overseas markets. It will generate about 10,000 jobs," said Gupta.

Similarly, Sonali Power has signed a pact with the state nodal agency (Udyog Mitra) to set up a solar power plant at Davangere at a cost of Rs 4,800 crore, which will generate 2,100 direct jobs.

Chief Minister B.S. Yediyurappa claimed several firms had come forward to collectively invest Rs 1 lakh crore since the BJP government came into being in July 2019.

"Many Indian and foreign firms will sign agreements with the state government at the 3-day Global Investors meet in Bengaluru on November 3-5," Yediyurappa said at the 'Invest Karnataka' meet.

Noting that Karnataka was rich in natural and human resources, especially in high-tech and skilled workforce, Yediyurappa said investment opportunities were plenty in aerospace, automobiles, machine tools, electric vehicles and bio-technology besides information technology.

"About 40 global firms expressed interest to invest in the state at a roadshow held at Davos, Switzerland, on the margins of the World Economic Forum (WEF) meet on January 23," he said.

Under the new industrial policy, the state government will set up clusters to make toys at Koppal, textiles in Bellari, solar equipment at Kalaburagi and farm machinery at Bidar.

"We are committed to make North Karnataka a power house of industries for the region's development, with Hubballi-Dharwad as the growth hub," Yediyurappa said.
