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.

New Delhi, Jan 25: The latest edition of the Oxford Advanced Learner's Dictionary features 26 new Indian English words, including Aadhaar, chawl, dabba, hartal and shaadi.

The 10th edition of the dictionary, which was launched on Friday, has 384 Indian English words and incorporates over 1,000 new words such as chatbot, fake news and microplastic.

The dictionary focuses on language change and its evolution through the years, and has ensured that the language and examples used in the new edition are relevant and up to date with the times, Oxford University Press (OUP) said.

The new edition comes with interactive online support through the Oxford Learner's Dictionaries website and an app. The website includes advanced features such as audio-video tutorials, video walkthroughs, self-study activities and enhanced iWriter and iSpeaker tools.

"This edition has 26 new Indian English words of which 22 figure in the printed dictionary. The other four are in the digital version," said Fathima Dada, Managing Director (Education Division) at OUP.

Some of other new Indian words in the dictionary are auntie (while aunty already figures in the English dictionary, auntie is an Indianism), bus stand, deemed university, FIR, non-veg, redressal, tempo, tube light, veg and videograph.

The four new Indian English words in the online version of the dictionary are current (for electricity), looter, looting and upazila (one of the areas that a district is divided into for administration purposes).

According to OUP, the new edition provides better, more accurate and understandable definitions with examples, usage notes and additional resources to help the learner use the right word in the right context.

"Prevalence and common usage are the main criteria for enlisting new words. We scan the globe for words which are often used by people while speaking English. Then these words go through a rigorous testing process," Dada said.

"As OUP is the custodian of English language globally, these words have to go through its processes," she told PTI.

The Oxford Advanced Learner's Dictionary, she said, has been reinventing itself for nearly eight decades, anticipating the growing learning requirements of learners.

"The 10th edition also is equipped with a strong digital support system, including an app," she said.

It is equipped with several digital tools. With iSpeaker, learners can get help preparing for speaking exams and presentations. With iWriter, learners can plan, write and review their written work. Text Checker allows the teacher to check any text against the Oxford 3000, 5000, and OPAL (Oxford Phrasal Academic Lexicon) written word list.

Resources accessible through online premium access include lesson plans, worksheets, video walkthroughs, and classroom and self-study activities. With the OALD app one can find 86,000 words, 95,000 phrases, 112,000 meanings and 237,000 examples.

The dictionary, which spans 77 years, was originally published in Japan in 1942 and was first brought out by OUP in 1948. The learner's dictionary is based on the original values of its creator, Albert Sydney Hornby, whose aim was to help language learners worldwide understand the meaning of English words.
