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.

Scientists
It 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.

Mangaluru, Dec 15: Educational institutions in Mangaluru that rely on the popular Mangala Stadium for their annual sports events are bracing for an inconvenience as the city's key sporting venue is set to close its gates for a significant upgrade. The stadium is expected to be unavailable for approximately two months starting from January 15, 2026.

The closure is necessitated by a proposed overhaul of the stadium's facilities, with a special focus on upgrading the synthetic track. Pradeep Dsouza, Assistant Director of the District of Youth Empowerment and Sports (DYES), Dakshina Kannada, confirmed the development.

"Experts have visited the stadium, conducted a thorough inspection, and have given the go-ahead for a complete makeover," Dsouza stated. "Funds have been allocated for the project, and we are currently awaiting the final green signal from state officials to commence the work. We anticipate that the work will likely begin in the second week of January. Consequently, we have stopped renting out the stadium to colleges and other organizations in preparation for the upgrade."

The timing presents a logistical challenge for colleges, as many schools have already concluded their sports meets.

"Colleges will now be organizing their events and will need to find alternative locations to host their sports meets," Dsouza added. He suggested a few potential venues, including the Dakshina Kannada police ground, University College grounds, Panambur grounds, Swaraj Maidan in Moodbidri, and the Mangalore University sports grounds in Konaje.

However, many institutions note that finding a comparable venue will be difficult. While the DK police ground and University College grounds are closer to the city center, they do not possess the extensive facilities and infrastructure offered by Mangala Stadium.

Dr. P Dayananda Pai - P Satisha Govt First Grade College, Carstreet, is one such institution dependent on the stadium. Principal Jayakar Bhandary expressed hope for a swift completion of the work. "We expect the work to be completed at the earliest. If not, we will be forced to look for other venues to host the sports day for our students," Bhandary said, highlighting the pressing need for the city's main sporting facility.
