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.

Karwar, Jun 3: The India Meteorological Department (IMD) has issued an alert, predicting thundershowers and heavy rainfall over north interior Karnataka, coastal Dakshina Kannada and Udupi over the next three days.

With Cyclone Nisarga hitting the Uttara Kannada coast on Tuesday,  parts of coastal Karnataka received heavy rainfall. Gusty winds tore through the coastal towns, as the sea too turned violent with rough waves smashing the shore.

The alert was issued with the advancement of Nisarga from east-central Arabian Sea to north Maharashtra, and adjoining south Gujarat coast. “Though it does not cover Karnataka, the range of cyclonic winds is very big and reaches north interior Karnataka also.

So an alert has been called out,” CS Patil, director in-charge, IMD, Bengaluru, said. The weather department has forecast a severe cyclonic storm and then a depression. Patil said formation of systems is a common factor before the onset of the monsoon and they help in its advancement.

“Cyclone Nisarga is helping in the quick advancement of the southwest monsoon to Karnataka, and the monsoon is likely to arrive before the scheduled date as conditions are favourable,” he added.

Bengaluru, Jul 7: Former Health minister and Congress MLA UT Khader has alleged that the state government has purchased coronavirus equipment for more than twice the actual price.

"Rs 500 sanitizers have been purchased for Rs 900 and Rs 9,000 has been paid to Rs 1200 for the thermal metre by the government. Instead of asking to allow him to work, Mr B Sriramulu, being health minister he must work for the people," he said.

He said that three months have passed since the pandemic started but the state government is still struggling to send ambulances to needy patients.

"Instead of ambulance it is sending final rights vehicle to needy people," Khader said.

According to the Ministry of Health and Family Welfare, there are 23,474 coronavirus cases in Karnataka including 13,255 and 372 deaths.

Mangaluru, June 21: A local court has held notorious serial killer Cyanide Mohan Kumar guilty in the murder of a 25-year-old woman from Kasargod. This is the 20th and the last case of Cyanide Mohan to be tried in the sixth additional district and sessions court. 

According to public prosecutor Jayarama Shetty, the victim was working as a cook in a ladies hostel and got in touch with Mohan Kumar, a teacher. He visited her house thrice and promised to marry her. On July 8, 2009, on the pretext of visiting a temple in Sullia, she left home, never to return. 

They had travelled to Bengaluru and three days later, when her family tried to reach her on phone, he told them that she had gone for a bath and that they were married and would be returning back home soon.

The next day Ramakrishna, a constable from Upparpete police station, found a lady lying unconscious outside the bathroom and he immediately rushed her to a local hospital, where she was declared dead on arrival. Like in all other cases, after staying in a lodge and having sex with the victim, he took her to the KSRTC bus stand and asked her to consume a cyanide laced tablet, stating it was a contraceptive pill. 

He asked her to leave behind the jewellery that she was wearing at the hotel room. An unnatural death report was registered and since none of her relatives had turned up for identification of the body, on July 15,2009 the body was buried.

The moment the Dakshina Kannada district police arrested the serial killer on October 21, 2009 and his pictures were all over the media, the family recognised him and the victim’s younger sister filed a missing complaint. The police had also recovered the victim’s jewellery from the house of Mohan’s second wife and the jeweller from whom he had purchased cyanide had also identified him. Meanwhile, the CID had taken over the case and a charge sheet was filed.

"The report from the Forensic Science Laboratory is crucial in this case as cyanide was found in the victim’s viscera. Mohan over the years has become a legal expert and in this case, he had sought two adjournments," said Jayaram Shetty. Mohan is currently lodged in the Hindalga central jail.
