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, Feb 7: The Bruhat Bengaluru Mahanagara Palike (BBMP) ordered the destruction of a tilted building in the city after evacuating about 150 people from 35 families in the vicinity, an official said on Thursday.

"The top portion of the building has been destroyed 70 per cent today (Thursday). Later, the destruction contractor will allow machines to be used," Bruhat Bengaluru Mahanagara Palike (BBMP) Yelahanka joint commissioner Ashok said.

Located on Vinayaknagar Street in Hebbal's Kempapura, the five-storey building being used as a hostel for boys got tilted on Wednesday morning, spreading panic in the neighbourhood.

Though the tilted building owned by one Rahul, a jeweller, was a sound structure, Ashok said a neighbour, Babu, hired a JCB excavator to dig deep beside the affected structure to build his own structure.

"Babu not only dug very deep but also damaged the foundation pillar of the tilted building, weakening the structure and leading to its slant," said Ashok.

Babu has been booked and arrested even as the police are on the look-out for the JCB owner and operator.

The titled building erected five floors unauthorisedly and falls into the B Khata category. It was constructed without the civic body's plan, said Ashok. 

A Khata and B Khata denote the two types of khatas that exist under BBMP. Khata is a document which shows a property owner having an account with the municipality to pay taxes. An A Khata denotes that the building owner has paid relevant property taxes and that the building conforms to building bylaws and government rules. A B Khata denotes that the building is in violation of government regulations regarding properties in Bengaluru, even when the civic charges for the property have been cleared by the owner.

"As per procedure, we issue notice, but such constructions are rampant in the city. Under the BBMP jurisdiction, there are 15 lakh B Khata structures," said Ashok.

For all B Khata sites, the civic body does not give any plan and there is no proper control on them, he said.

Ashok said the case to regularise the B Khata buildings to A Khata buildings is currently pending in the Supreme Court.

Luckily, no injury or loss of life has been reported from the tilted building.

The civic body arranged alternative accommodation for the affected families, but most of them chose to stay with their relatives, said Ashok.

Bengaluru, Jul 8: In a setback to the State government, the Karnataka High Court on Wednesday stayed the initial ban and the subsequent restrictions imposed on schools against conducting online classes from pre-primary to Class X.

Prima facie the ban and embargo imposed on online education violate Articles 21 and 21A of the Constitutionon the fundamental right to education, the Court said.

A Division Bench comprising Chief Justice Abhay Shreeniwas Oka and Justice Nataraj Rangaswamy passed the interim order staying the operation of Government Orders issued on June 15 and June 27 respectively.

The Bench passed the interim order on the petitions filed by parents of children and several educational institutions questioning the legality of the ban and the restrictions imposed.

However, the Bench made it clear that this order should not be construed that the schools have right to make online education compulsory and can charge fee for offering online education. Also, the schools should not deprive students, who cannot opt for online education, the lost education when the schools reopen on regular basis.
