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, Mar 8: Lieutenant General Milind Hemant Thakur, Director-General of Supply and Transport Corps of the Indian Army, unveiled the renovated Animal Memorial at Agram Grounds in ASC Centre and College here on Saturday.

The animal memorial signifies the contributions of mules and horses of the Indian Army. These animals belonging to the Army Service Corps, who have rendered their services relentlessly during the war in the Himalayas, often paying the highest price of sacrificing their lives in the line of duty have been chronicled in the Memorial.

To ensure that these hoof prints do not get obliterated, on approval by the Government of India, their saga was brought to life in the form of a sculptured monument in the Equestrian Training Area of the ASC Centre and College.

This animal transport memorial has now been extended by constructing two walls supported by Roman pillars on either side.

These walls highlight the role played by the animals in the Indian Army since the British Raj. It gives details of 637 gallantry awards won by the brave muleteers, 49 battle casualties since independence, 14 gallantry awards to mules since independence and 05 military recognitions bestowed by the Chief of the Army Staff and other Army Commanders on AT units, who have been relied upon heavily to fill an important niche in the logistics networks of the Indian Army.

Gen Thakur also declared that 26 September each year has been nominated as the AT Remembrance Day as it was on this day in 1914, that 9th mule Corps, as part of the Indian Expeditionary Force, landed at Marseilles in France, to a most hearty and enthusiastic welcome by the French to support the British and allied armies in World War One.
