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, Apr 18: Virtually defending the Gowda family for conducting a marriage reportedly defying lockdown restrictions, Chief Minister B S Yediyurappa on Tuesday said it was performed in a simple manner and well within their limits, "for which they are to be congratulated."

"All the necessary permissions were given and the marriage was performed in a simple manner. There is no need to discuss about it. They had done it well within their limits for which I congratulate them," Yediyurappa said to a query from reporters during the post-COVID-19 briefing.

Scores of people had thronged a farmhouse on Friday to get a glimpse of the wedding of former Prime Minister and JD (S) supremo, H D Deve Gowda's grandson Nikhil Kumaraswamy, ignoring appeals not to visit the venue in view of the ongoing lockdown to check the COVID-19 outbreak. Nikhil, son of former Chief Minister H D Kumaraswamy, tied the nuptial knot with Revathi, the grand-niece of former Karnataka housing minister M Krishnappa.

The marriage was solemnised at Kumaraswamy's Kethaganahalli farmhouse at Bidadi in the neighbouring Ramanagara district, a JD(S) stronghold. Kumaraswamy had taken to Twitter after the marriage, thanking his party MLAs, leaders and workers for staying away from the event and blessing his son from their houses. In a series of tweets, he had said social distancing was maintained and all precautionary measures were taken throughout the event.

BJP had hit out at the JD(S) first family for flouting the norms, alleging that at least 150 to 200 vehicles were given permission to attend the event, that too at at time when social workers wanting to serve the badly affected poor people were not being allowed to ply any form of transport JD(S) leader N H Konareddi and MLC T A Sharavanna had denied the charges, saying the union government guidelines had been followed and that social distancing was maintained.

Udupi, June 2: The number of positive cases may continue to be more in Udupi district since the results of more than 3,000 samples are pending with Labs.

The district total cases to 260. The figure had seemed far-fetched on May 15, when the number of cases stood at just three. The latest spike has been attributed to the return of migrants from other States as well as from abroad. These samples are from people who returned to the district in the last two weeks.

This delay is because the laboratories testing samples from Udupi are burdened with a high case-load after more than 8,500 people returned to the district, particularly from the neighbouring state of Maharashtra.

"Samples have piled up after the influx of people returning from other states and from abroad," says Dr Prashant Bhat, nodal officer for COVID-19 in Udupi. This delay has caused returnees in institutional quarantine to stay on for as long as 18 days.

The designated laboratory for coronavirus testing in Udupi is Wenlock District Hospital in Mangaluru. The district administration also sends samples to laboratories at the Kasturba Hospital in Manipal, Yenepoya Medical College, Mangaluru, KS Hegde Medical Academy, Mangaluru, and Viral Diagnostic Laboratory in Shivamogga. Apart from Udupi, the laboratory in Manipal is also testing samples from Uttara Kannada district. The laboratory in Shivamogga is also testing samples from Shivamogga and Bijapur districts. The laboratories in Mangaluru, similarly, have samples from Dakshina Kannada district.

Dr Avinash Shetty, Medical Superintendent of Kasturba Hospital in Manipal, one of the private laboratories being used by the Udupi district administration, said that they are testing samples in batches. "We received around 600 samples today and we will be testing them now. The backlog of samples should be cleared in the next few days," Dr Avinash said.

All 73 cases reported in Udupi on Monday were patients with travel history of returning from Maharashtra or patients with travel history of returning from abroad.

In cases of some patients who tested coronavirus positive in the past week, people were released from institutional quarantine after a stipulated period only to be tracked down again and admitted in hospitals after their results returned positive.

While two such cases emerged in Belapu and Belman in the district, the administration is now following up with others who were released from institutional quarantine to ensure they remain in home quarantine till their test results are confirmed.

The spike in cases among returning migrants in Udupi also comes at a time the Karnataka government reduced restrictions on interstate travel.
