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 19: Containment zones in Karnataka will be much smaller in size under the latest lockdown norms. However, rules and loopholes will be tightened and action against violators will be stringent in order to check the spread of the disease.

Revised guidelines issued by the Centre to the state, reveal containment zones are delineated based on mapping of cases and contacts. Intensive action will be carried out in these areas with the aim of breaking the chain of transmission. Therefore, the area of a containment zone should be appropriately defined by the district administration/local urban bodies with technical inputs at local level.

The health department is considering shrinking the size of containment zones from the existing 100 metres to open up more space for economic activities. Medical education minister K Sudhakar, also a member of the Covid taskforce, said additional chief secretary (health department) Javed Akthar will issue a new definition of a containment zone after the Covid-19 taskforce holds its next meeting.

“We are planning to further shrink it and restrict containment zones to an apartment complex, independent house or even a lane where the Covid-19 patient resides,” Sudhakar said. He went on to say bigger containment zones will impede businesses and normal activities in the vicinity, something which the government wants to avoid.

The minister said Karnataka will also do away with colour-coding districts. “With restrictions being relaxed for almost all activities, it does not make sense to pursue with colour codes. It is either containment zone or outside containment zone,” he said.

In rural areas, the minister said containment zones will be identified by the taluk heads. Government sources say it is difficult to restrict activities to certain areas or smaller location in rural areas as farmers and people will have to travel to the outskirts of their villages for their livelihood.

An official said, a containment operation (large outbreak or cluster) is deemed successful when no case is reported in 28 days from the containment zone.

Wayanad/Thiruvananthapuram, Apr 24: Amid the strict lockdown, a school teacher travelled from Thiruvananthapuram to Muthanga in Wayanad -- a distance of about 465 km -- on her way to neighbouring Karnataka en route to Delhi following which cases have been registered against her and an excise official.

The woman, Kamna Sharma, said to be working in Kendriya Vidyalaya, Pattom, undertook the journey on April 21 along with her two year-old daughter, police sources told news agency PTI.

An Excise Circle Inspector, Shahjahan, had provided his vehicle to travel allegedly on the instructions of Malappuram excise officer, in whose private vehicle, the woman and the child had reached Wayanad border from Thiruvananthapuram, the sources said.

The two were charged under the Kerala Epidemic Act and various sections of the IPC including sect 269 (negligent act likely to spread infection) and 271 (disobedience to quarantine rule).

Because of the lockdown even inter-district travel is not allowed by police and district administration, unless there is an extremely genuine reason.

A senior police official in Thiruvananthapuram said he does not remember issuing any such pass.

The woman may have "misused" government machinery as private vehicles would have been stopped somewhere during the long journey, he said.

She came to Kalpetta in Wayanad allegedly in an official car of the excise department.

Wayanad District police chief R Elango said that an FIR has been filed based on preliminary information and investigations have begun.

"We will check if she has followed procedures in obtaining a pass and if she made any false claim to get the pass."

As per preliminary information the woman came in an excise official's car from Thamarassery (Kozhikode) to Muthunga(Wayanad), he said. Her mode of transport before that--from Thiruvananthapuram to Wayanad--will also be investigated, he said, adding they have no information if she has reached Delhi.

"We will track down her movement," he said Meanwhile, theWayanad district administration has intensified the lockdown protocol from Thursday to prevent people's movement within and from outside the district/state.

Interception at all the check posts on district an state borders of the district, bordering Tamil Nadu and Karnataka, will also be intensified. No one would be allowed to travel frequently to and fro the district under the pretext of official duty.

Wayanad collector Adhila Abdulla said officials from outside the district will no longer be allowed to commute daily.

"Elderly people above the age of 65 should confine to their homes unless it is extremely urgent or unavoidable. Cases will be registered against family members who allow elderly people to go out for buying medicines and other essentials," she said.

Senior citizens, who live alone, can call either the Fire (101) or Police (100) departments for any help and to get things they need, the collector said.

Whatever relaxations were in place have also been withdrawn with effect from Thursday, she added.

Wayanad and Thiruvananthapuram come under the "Orange B" zone where there are some relaxations.

However, Thiruvananthapuram city limits falls under the hotspot area.

Police said a case was also registered against a doctor and her husband who entered Kerala from Tamil Nadu border.
