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.

Mangalore University has been participating in the campus bird count a sub-event of ‘Great backyard bird count’ (GBBC) organized by Bird Count India for the past 5 years. This year, CBC was held from 14th to 17th February of 2020 across various campuses in India.

This year the four days event was successfully ended up with the sightings of 103 species of birds from various locations across the campus spread on 300 acres. In this Black Drongo, Black Kite, Brahminy Kite, Common Iora, Green Wabler, Purple-rumed Sunbird, Red-whiskered Bulbul, White-cheeked Barbet, Jungle Babbler and Plum headed parakeets were the common birds, and also observed House Crow with nest and nestlings, Indian Robin nest with eggs, Bronzed Drongo constructing the nest and Shikra mating and carrying nesting materials.  Whereas Yellow-billed Babbler is rare in the campus, Ashy Drongo, Barn Swallow, Booted Eagle, Grey Wagtail, Indian Pitta etc. were migratory birds, Grey-headed Bulbul (Near Threatened bird), Rufous Babbler and Grey-headed Bulbul were Western Ghats Endemics  and Brown Wood Owl, Barn Owl, Spotted Owlet, Nightjars (Savanna, Indian and Jerdon’s) and Sri Lanka Frogmouth were nocturnal birds. Blue-eared Kingfisher Grey-bellied Cuckoo which was very rare and new additions to avian list of the campus.

In the first year (2016) of Mangalore University’s CBC recorded 77 species, in 2017 recorded 95 species, in 2018 recorded 110 species and in 2019 recorded 107 species of birds. However some of the common species like Rose ringed parakeets, Blue tailed bee-eater, Nilgiri Flowerpecker and Indian roller etc., sighted last year were not seen this year. But with 2 new additions from this CBC, the checklist of Mangalore University Campus has been updated with a total of 141 species.

This event was coordinated by Vivek Hasyagar from the Department of Applied Zoology and Maxim Rodrigues from the Department of Marine Geology. Survey trails were led by more than 60 students and research scholars from various Departments of Mangalore University includes Applied Zoology, Biosciences, Microbiology, Botany, Physics, Chemistry and Material Science.  In addition, some enthusiastic participants from St. Aloysius College had involved in identifying the birds around the campus.

Quote:

Wild/planned fire affects negatively on the existing ecologically sensitive areas in and around the campus especially in lateritic grasslands. Because many insectivorous birds are dependent on these lateritic grassland habitats for their food and breeding grounds for many ground dwelling birds like Yellow wattled lapwing, Red wattled lapwing, Indian Robin and Barred buttonquails. Conserving these habitats will be helpful in protecting these birds.

Quotes from the participants: “The Campus Bird Count 2020 at Mangalore University was an experience of its own kind. Observing birds in their natural habitat gave me new perspective of viewing them not only as another living being, but as equals, or even of higher intelligence. The Campus Bird Count is an important step towards documenting bird life year after year, and creating awareness amongst youngsters, so that proper conservation steps can be taken to protect them from human interference”.

Lucknow, Apr 29: Tablighi Jamaat members, who got cured of COVID-19, have been asked by their organisation to donate their plasma for treatment of other coronavirus-infected patients, a move that the outfit thinks will help it shed its “villain” tag.

"Maulana Saad, in an open letter on April 21 to all Jamaatis who have recovered from the coronavirus (infection), has appealed them to donate their plasma to help others. The message has reached all the members," Maulana Anees Ahmad Nadvi, the manager of Tablighi Jamaat’s Lucknow branch, told PTI PTI on Wednesday.

"As per the Health Department data, over 50 per cent of corona patients are Jamaatis. Among them those who have recovered are being contacted and all of them are ready to donate their plasma," claimed Nadvi.

"We have till now contacted 400 Jamaatis. In the entire country, those who have recovered are also giving their plasma. Markaz has given instructions that no one should be left from donating plasma," he said. "Jamaatis are not doing any favour to anyone by giving their plasma.

This is a humanitarian step. This is true that Jamaatis are being presented as villains after coronavirus spread, but Maulana Saad has asked us to forgive those doing this," he said. Tablighi Jamaat leader Maulana Saad Kandhalvi is on the run after an FIR was registered against him by the Delhi police for organising a religious gathering in March this year despite restrictions to combat the coronavirus spread.

With some plasma therapy trial results rekindling hopes of it being a likely cure for COVID-19, the Uttar Pradesh government too had begun contracting patients cured of it for plasma donation, but the move was suspended after the Union Health Ministry on Tuesday said the therapy was only at an experimental stage and there was no evidence yet to support that it can be used as treatment for COVID-19.

Uttar Pradesh Surveillance Officer, Dr Vikasendu Agarwal, said all those who have recovered from coronavirus, including Jamaatis, were being contacted for plasma donation, but the move has been suspended after the Centre’s statement on the issue.

Refusing to divulge the number of cured Jamaatis, he said "We were contacting them. They are not different from us. We were contacting all our patients and asking them that they could donate if they find it appropriate, as it would help other patients." "All of those contacted by us are ready for giving plasma," he said.

Chief Medical Officer, Lucknow, Dr Narendra Agarwal said all 28 Jamaatis, who were admitted in KGMU were contacted to donate their plasma and all of them agreed. "A proposal in this regard has been sent to the government.

After approval, their plasma will be taken," he said. With the plasma therapy gaining a lot of traction as a possible cure for coronavirus, the Union Health Ministry on Tuesday clarified that it is at an experimental stage and there is no evidence yet to support that it can be used as treatment for COVID-19. Till the effectiveness of this mode of treatment is scientifically proven, its application except for research and clinical trial is illegal, Joint Secretary in the Ministry of Health Lav Agarwal said.

Dr Vikasendu said after the Centre's clarification contacting people for plasma donation has been put on hold. A further step will be taken on decision of KGMU which is working on plasma therapy here, he added.

Bengaluru, Jan 21: Braving the biting cold, chief minister BS Yediyurappa took time out of his busy schedule to go around Davos on Monday.

Clad in a long coat over a suit, scarf and leather gloves, Yediyurappa, with secretary S Selvakumar in tow, took in the sights of well-laid bylanes, quaint houses and snow-covered pine trees. He also rode a cable car at Persenn.

A cook from Andhra Pradesh, who works at an Indian restaurant in Davos, served the CM shavige uppittu and khara pongal for breakfast. Yediyurappa had chapatis and rice for dinner.

Meanwhile, Karnataka is likely to have a ‘Centre for Internet of Ethical Things’, perhaps, the world’s first, which will seek to ensure ethical practices in trade and businesses, besides addressing issues like misuse of artificial intelligence, a concern that has been bothering business leaders across the globe.

At the World Economic Forum in Davos, Yediyurappa signed an informal agreement with Murat Sonmez, the forum’s managing director, on Monday. "Investors around the globe are worried about unethical practices in business and a centre is the need of the hour," Sonmez was quoted as saying in a press release. "If the Karnataka government is serious about securing investment, it should set up the centre immediately."

Yediyurappa immediately responded to the suggestion by prompting Sonmez to write down an informal agreement on a sheet of paper which both signed. "This centre will go a long way in Karnataka’s history of industrial development," Sonmez was quoted as saying in a release by the Karnataka delegation.

At the inauguration of Karnataka’s pavilion, Yediyurappa promised all support to investors. "We are happy to be here and look forward to engage you on various development agenda," he said adding that he was keen to partner on certain strategic research that can help Karnataka become a major player on the global stage. "With Karnataka emerging as a leading industrial state in India, we can make it a major player on the global stage," he said.

Industries minister Jagadish Shettar, chief secretary TM Vijaya Bhasker and industries secretary Ramana Reddy were also signatories to the informal agreement.
