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/Mangaluru, Aug 6: Battered by torrential rains, several parts of Karnataka are facing a flood-like situation for the third consecutive year, putting lives and property at risk. 

Several districts of the state's coastal, Malnad and north interior regions are receiving heavy rains and the showers are expected to continue, while there are reports of landslides in hilly areas of Kodagu and Chikkamagaluru districts.

With flood-like situation in several parts of the state, Chief Minister B S Yediyurappa, who is currently undergoing treatment for COVID-19 infection at a private hospital here, has ordered immediate release of Rs 50 crore for emergency relief.

"In wake of heavy rains in several parts of the state, I have instructed the Chief Secretary to review the situation and issued instructions to DCs (Deputy Commissioners) to closely monitor the situation & take necessary measures. Also ordered immediate release of Rs 50 crores for emergency relief purposes," he tweeted last night.

A statement released by the CMO on Thursday said, Yediyurappa has directed the district in-charge Ministers to take precautionary measures in the wake of heavy rainfall across the state.

He instructed the ministers to remain in their constituencies and tour the damaged areas and also directed them to undertake relief distribution and other necessary measures.

"Rs 50 crore has already been released and if necessary more funds would be released. The ministers can take decisions regarding emergency works," he added.

Revenue Minister R Ashoka said he had spoken to Deputy Commissioners of all the districts and given them necessary instructions to respond immediately to the situation.

He has called for a meeting of the disaster management authority later today.

Home Minister Basavaraj Bommai said he will be holding a meeting with the State Disaster Response Force (SDRF) regarding relief and rescue measures to be taken.

Parts of districts in coastal and Malnad regions are currently under red alert and rains are likely to continue there.

Officials said, "... depending on the situation we will downgrade the alerts, it (rains) is likely to reduce during the next couple of days...wind speed is also high some parts, it may also reduce."

In Kodagu district along with widespread rains, landslides have also occurred.

There have been landslides at Brahmagiri, near Talacauvery, the origin of river Cauvery.

"At least four to five people- including the Talacauvery temple priest and family are currently missing... rescue teams have reached the spot," officials said, adding that sensing danger the priest had been asked to vacate the house earlier but he did not.

This is the third consecutive year that Kodagu is facing floods and landslides.

Several parts of north Karnataka, especially the border district of Belagavi are also facing flood situation as inflow has increased in Krishna river and its tributaries due to heavy rains in neighboring Maharashtra and also in the district.

With inflow increasing in Tungabhadra river, there is flood like situation in parts of Ballari district also.

There is a similar situation in Uttara Kannada district that is battered by rains and heavy winds.

The swollen Gangavali river has caused flood like situation in parts of the district.

Due to continuous rains in coastal and Malnad region several rivers including Netravati are swollen and gates of the dams have been opened.

There are also reports of heavy rains and wind causing destruction to crops in parts of Dharwad and Haveri among other districts.

The Karnataka government had recently said it has identified 1,989 villages and over 51 lakh people in 19 districts as flood prone.

As a temporary arrangement for those who will be affected by floods, as many as 1,747 relief centres have been identified- they are schools, anganwadi centres, community centres among others, Minister Ashoka had said recently.

In August 2019, Karnataka witnessed one of its worst natural calamities when heavy floods affected 103 taluks in 22 districts, killing more than 80 people and displacing nearly seven lakh people.
