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.

Jan 2: A year after 12,000 acres of forests in Bandipur went up in smoke, the Karnataka Forest Department is gearing up for the summer even as the Forest Survey of India (FSI) has cautioned that 22.78 lakh acres (9,222 sq km) or about 20% of the green cover spread across three districts in the central part of the state is fire-prone.

The FSI studied forest fire incidents across the country between 2004-05 and 2017 before coming up with state-specific inputs.

According to the 13-year observation, Karnataka has 7,352 “fire points” or areas measuring 5 km X 5 km with frequent fire incidents.

Though the number is lower compared to states like Maharashtra, Madhya Pradesh and Odisha with over 20,000 points, the sheer spread of the fire-prone area itself is a challenge for the Karnataka Forest Department.

According to data, about three lakh acres (1,199.9 sq km) of forest area is very highly fire prone with 26 to 52 fire incidents in 13 years. This is followed by 7.6 lakh acres (3,067 sq km) of “highly fire prone” areas with an average of one to two incidents every year.

Almost all of the “red alert” areas are concentrated in Uttara Kannada, Chikkmagaluru, Shivamogga and Chamarajanagar districts. As temperature rises at the end of January, so does the risk of forest fires, requiring officials to be on vigil till the end of summer.

After an investigation into the Bandipur blaze revealed that faulty fire lines and poor supervision were the reason for the spread of the fire, the department has come up with a multi-pronged approach to prevent similar incidents this year.

“After the Bandipur incident, we have created a fire cell and a standard operating procedure (SOP) which everyone has to follow. Firstly, a fire management plan is prepared and approved by a competent authority.

The SOP has well defined firelines which have to be executed by December-end and burning must be completed by January 15,”  Principal Chief Conservator of Forests (Head of Forest Force) Punati Sridhar told DH.

He said that to ensure its strict implementation, GPS readings of firelines are to be submitted for random verification.

“All the required equipment from fire jackets to shoes, gloves, backpack sprayers and tractors mounted with 2,000-5,000 litre tanks with high pressure pumps will be deployed at vantage points,” he said.

In addition, the department’s fire cell works in collaboration with the Karnataka State Remote Sensing Applications Centre (KSRSAC) to give fire alerts within half and hour of an area catching fire and detected by satellites.

“Earlier, the gap used to be four hours by when the fire would have spread beyond control. Now, with reduced time gap, it would be easier to control fire early,” he added.

Bengaluru Jul 29: There will be a centralised system in place in Karnataka to classify asymptomatic, symptomatic and mild symptomatic persons and recommend treatment based on the severity of the cases, said Medical Education Minister Dr K Sudhakar on Tuesday here.

"Various existing apps related to COVID-19 will be brought under one platform to get real-time information which will assist in strategising allocation of hospitals/beds to the needy. This will probably remove the delay in bed allocation and treatment which is being faced now. The patients will get all information in one phone call," Dr Sudhakar said.

Sudhakar spoke with a team of experts from the government and Infosys.

Referring to a company by name Step 1, which is providing such services in Delhi and Madhya Pradesh, the Minister said that a similar system will be implemented in the state as well.

"This company is having a team of doctors and nurses which is guiding the people whether they need hospital treatment or home isolation after they are tested positive for COVID-19. More than 70 per cent of the positive cases are being asymptomatic or mildly symptomatic and are advised to go for home isolation," the minister said.

"The load on the hospitals is reduced and severe cases can be administered proper treatment. Infosys co-ordinates with the government to provide technical support for this system," Dr Sudhakar added.

Earlier during the day, the minister held a video conference with the heads of private medical colleges to review COVID preparedness.
The government has already passed guidelines to allocate 50 per cent of hospital beds for COVID patients.

Bengaluru, Jul 2: Karnataka Health Minister B Sriramulu on Thursday launched the ICU Telecard, developed by CISCO to address the concerns of doctors treating coronavirus patients.

Wi-Fi networks and Cisco Health platform help to protect the entire medical team dealing with the infected person by ensuring that doctors do not have to be inside isolation wards and COVID ICUs.

The ICU Telecard has been installed at Victoria and KC General hospital.

"This technology is a necessity to safeguard health of our doctors and it should be implemented in all hospitals. We will discuss about this in the task force meeting and decide regarding the use of this technology in all COVID hospitals in the state. For now, we have installed one at Victoria and KC General hospital" said the minister.

Addressing the complaints of non-release of dead bodies without coronavirus testing, Sriramulu said: "Experts have discussed the same in a meeting with the Chief Minister yesterday, who has ordered for an increase in the number of testing labs. This should resolve the issue. We are also contemplating the conduct of plasma therapy in all districts."

The minister said that the government has also decided to reserve two ambulances for every ward to address the issue of non-availability and will procure more ambulances on rent if the existing ones are insufficient.

He further informed that those who were seen dumping the bodies in a pit in Ballari have been suspended and notice has also been served to officials in Yadagiri.

"We will ensure such instances do not repeat in the state," he said.
