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, May 3: Erection of barricades and drawing up of boxes or circles aimed at maintaining social distancing were seen in front of liquor shops in different parts of Karnataka on Sunday, a day ahead of their reopening after a gap of over 40-days, due to the lockdown.

Karnataka Excise Commissioner on Saturday had ordered that only CL-2 (retail shops) and CL-11C (state-run retail shops like Mysore Sales International Limited) would open from May 4.

It had permitted liquor sale liquor between 9 am and 7 pm only in areas that are outside COVID-19 containment zones.

Reports of barricades being erected to ensure that people stand in line and drawing of boxes or circles in front of shops to maintain social distancing in front of retail and MSIL shops have emerged from across the state, including the state capital.

Also reports about shop keepers doing special poojas outside liquor shops in Kolar and some even illuminating their outlets with lights from outside have surfaced from other parts of the state.

Meanwhile, officials were engaged in checking stocks ahead of the shops opening on Monday morning.

"We are making all preparations to ensure that government rules are followed. We also seek the cooperation of the people and police," the manager of a shop said.

Another said there may be a rush initially, after which things may get back to normal.

"We expect things to go on smoothly," he added.

Calling for number of customers to be limited to five at a time while ensuring that they maintain social distancing of not less than six feet distance, the order states that customers and the staff will have to wear masks and sanitizers should be used at the shops.

Only stand alone CL-2 and CL-11C shops are allowed to commence liquor sale and not those at malls and super markets, it said.

Officials in Bengaluru said liquor sale is prohibited in 26 containment zones in the city, while in other places rules that have been prescribed need to be followed.

In case of any violation, strict action would be taken, including imposing of penalty, they said.

There was pressure on the government to kick start economic activities, including allowing sale of liquor, to boost the state's finances as excise is the key area which generates revenue.

State Excise Minister H Nagesh had recently pegged the losses at Rs 60 crore per day because of closure of liquor shops, due to the lockdown.
