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, Feb 27: The Centre has adopted Prime Minister Narendra Modi's mantra of "Make in India', for India and the world" to build strong defence and security infrastructure in the country, said Defence Minister Rajnath Singh after inaugurating the new Light Combat Helicopter Production Hangar at Helicopter Division in Hindustan Aeronautics Limited (HAL) Complex here on Thursday.

According to an official statement, the Defence Minister said in the last five years, India has made significant progress towards manufacturing military equipment indigenously under the 'Make in India' initiative.

Stressing that the defence industry plays a major role in the economic development of the country, Singh lauded the significant contribution of organisations like HAL.

Highlighting the Rs 35,000 crore exports target set for the coming years, he expressed confidence that HAL, through its various platforms, will contribute significantly to achieve this milestone.

According to the statement, Rajnath Singh commended HAL for being the backbone of the Indian Air Force and meeting the requirements of the Armed Forces.

"The HAL has excelled both in operations and finance in the last five years. It has achieved operational clearance on seven platforms, including Light Combat Aircraft and Light Combat Helicopter, and overhauled platforms like Hawk and SU 30 MKI," he said.

He also appreciated that HAL had a turnover of Rs 19,705 crore till March 2019 and it gave shareholders a healthy dividend of 198 per cent.

HAL also apprised the Defence Minister on the progress of the new design and development programme of indigenous Indian Multi-Role Helicopter (IMRH), the statement informed.

The full-scale mock-up was showcased to Rajnath Singh. The IMRH is proposed as a replacement to the existing medium-lift helicopters such as Mi17's, Kamovs and Seakings which will phase out in the next eight to ten years.

LCH is a 5.5-tonne class combat helicopter designed and developed by HAL. It is powered by two Shakti engines and inherits many technical features of the Advanced Light Helicopter. LCH has the distinction of being the first attack helicopter to land in Forward Bases at Siachen, 4,700 mts above sea level with 500kg load.

A 7-year-old Dalit girl who had gone missing from outside her residence in Tamil Nadu’s Pudukkottai district on June 30 was found dead last evening. 

Police sources said that the body with severe injures was found in a forest area bordering her village. The young girl had been sexually assaulted before the murder, according to police.

Victim’s neighbour, Raja, 25, who belongs to the Pandaram caste, has been arrested in connection with the incident.

While they have included murder charges in the First Information Report (FIR) against him, they are awaiting the post-mortem report to add sections of the Protection of Children against Sexual Offence Act (POCSO act) in the FIR.

"The girl was playing outside her home at 4pm. Her parents then found her missing and her father filed a complaint at the station at around 7pm. Efforts were then underway to find the girl," said an investigating official.

They found the minor's body in the forest area near her village on the evening of July 1. Her clothes were in a state of disarray and her face was severely injured.

"She has been beaten with sticks on the face and injuries are clearly visible. The post-mortem will reveal the actual cause of death," says an official from the district.

Police sources further add that the neighbour had found the minor roaming around the area on Wednesday and allegedly took advantage of the fact that she was alone.

"During inquiry he admitted that he had sexually assaulted and murdered the girl," says a police official from the district. "Further investigation is underway and we will have more clarity once we get the post mortem report," he adds.
