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, Jul 11: Amidst the mounting number of covid-19 cases, Karnataka is witnessing another disturbing trend of increasing number of people ending their life. After the lockdown was relaxed, the state saw a worrying jump in the number of suicides.

According to statistics, as many as 2,211 suicide cases have been registered in just two months. The number of suicides rose by 23% in May to 1,127, and by another 18% in June to 1,084, from an average of 912 suicides in the first three months of the year. 

In April, however, the number nearly halved to 477. But April was also the month during which the lockdown (announced on March 24) was complete, and everyone was at home -- which, experts say, could have prevented people with suicidal tendencies from taking their own lives.

Shockingly, number of teenagers including school children committing suicide also increased in the state in past couple of months.

With the pandemic still accelerating and impacting people in multiple ways, the World Health Organisation has urged people to pay greater attention to mental health and suicide prevention. 

Dr Poonam Khetrapal Singh, Regional Director, World Health Organisation (WHO), South-East Asia Region, said stigma related to Covid-19 infection may lead to feelings of isolation and depression. Another precipitating factor impacting mental health amidst Covid-19 could be domestic violence, which is reported to have increased globally as several countries imposed lockdowns, she said.

“Hitting lives and livelihoods, the pandemic is causing fear, anxiety, depression and stress among people. Social distancing, isolation and coping with perpetually evolving and changing information about the virus has both triggered and aggravated existing and pre-existing mental health conditions, which need urgent attention,” she said.

Dr H Chandrashekar, professor and head of the department of psychiatry at Victoria Hospital, said reasons for suicide are always multi-factored, combined, cumulative, unresolving and interrelated.

“There is grief everywhere now due to deaths related to Covid-19, and it may have an adverse effect on some. But people should be watchful of their family members, especially those who are in depression and have a history of suicide attempts. One should never ignore signs, like when someone says they feel like ending their life. They should not be left alone, and unconditional support needs to be given. Also, objects that could be used to commit suicide must be kept away from them,” Dr Chandrashekar said.

Bengaluru, May 26: After Yogi Adityanath said that no state can take manpower from Uttar Pradesh without his government's permission, Karnataka Pradesh Congress Committee (KPCC) president DK Shivakumar on Tuesday termed the Uttar Pradesh Chief Minister's move as "unconstitutional" and "against the right to freedom of movement."

"Uttar Pradesh Chief Minister Yogi Adityanath's move to restrict hiring people of Uttar Pradesh is unconstitutional and goes against the right to freedom of movement. Mr Yogi, please note that UP is not the private property of your govt. The people of Uttar Pradesh don't need your government's permission to work anywhere in India," Shivakumar tweeted.

"Mr Yogi doesn't understand the basic rules of governance in a democracy. Such actions lack common sense and will only make the people of Uttar Pradesh suffer more. When it's convenient for BJP, it's One Nation, when it's not, it's different states and different people. Heights of hypocrisy," he added.

Adityanath had on Monday said that the state government will provide social security and insurance to labourers and no state can take manpower from Uttar Pradesh without his government's permission.

"If any state wants manpower, they cannot take our people from the state without our permission as there were reports of misbehaviour with them in other states. We are taking full responsibility for labourers' social security. We will provide every kind of security to them including insurance. Wherever they will go, we will always stand by them," Yogi said.

The Chief Minister said that skill mapping is being done in Uttar Pradesh and a commission will be set up for labourers to ensure employment for them.

On Sunday, Adityanath had ordered the formation of a 'Migration Commission' for the purpose of providing the workers, who have returned to the state during the lockdown phase, with employment suited to their skills.
