Light from smartphones may lessen your sleep quality

Houston, Jul 29: Artificial light emitted from digital devices such smartphones and tablets could reduce the quality of your sleep, a study has warned.

The largest source of blue light is sunlight, but it is also found in most LED-based devices. Blue light boosts alertness and regulates our internal body clock, or circadian rhythm, that tells our bodies when to sleep.

This artificial light activates photoreceptors called intrinsically photosensitive retinal ganglion cells (ipRGCs), which suppresses melatonin, the hormone that signals your body that it is time to sleep.

"The most important takeaway is that blue light at night time really does decrease sleep quality. Sleep is very important for the regeneration of many functions in our body," said Lisa Ostrin, assistant professor at University of Houston in the US.

In the study, participants, aged between 17 and 42, wore short wavelength-blocking glasses three hours before bedtime for two weeks, while still performing their nightly digital routine.

Results showed about a 58 per cent increase in their night time melatonin levels.

"Those levels are even higher than increases from over- the-counter melatonin supplements," said Ostrin, who led the study published in Ophthalmic & Physiological Optics.

Wearing activity and sleep monitors 24 hours a day, the 22 study participants also reported sleeping better, falling asleep faster, and even increased their sleep duration by 24 minutes a night, according to Ostrin.

Ostrin recommends limiting screen time, applying screen filters, wearing computer glasses that block blue light, or use anti-reflective lenses to offset the effects of artificial light at nighttime.

Some devices even include night mode settings that limit blue light exposure.

"By using blue blocking glasses we are decreasing input to the photoreceptors, so we can improve sleep and still continue to use our devices.

That is nice, because we can still be productive at night," Ostrin added.

New Delhi, Feb 3: In the third such incident inside of a week, two unidentified persons opened fire outside Gate No. 5 of Jamia Millia Islamia on Sunday night, the Jamia Coordination Committee (JCC) said.

A statement issued by the committee, a group comprising students and alumni of the university formed to protest against the Citizenship Amendment Act, said the attackers were on a red Rcooty.

No one was injured in the attack. One of the miscreants was wearing a red jacket, the statement said.

"Firing has taken place at Gate No.5 of Jamia Millia Islamia right now by two unidentified persons. As per report, one of them was wearing a red jacket and driving a red Scooty having vehicle no. 1532 or 1534," the statement said.

Police said they were verifying the JCC's claims.

Asim Mohammed Khan, former Congress MLA from Okhla, said the incident occurred around 11.30 pm. "We heard the gunshot. That is when we stepped out to see and the two men left on a Scooty," a student said.

"We have taken down the vehicle number and called police," he added.

This is the third firing incident in the Jamia Nagar area in a week.

On Thursday, a minor fired at anti-CAA protesters marching towards Rajghat, injuring a student.

Two days later, a 25-year-old fired two rounds in air in Shaheen Bagh in Jamia Nagar. No one was hurt in the incident.

The incident on Sunday night triggered panic in the area. A police vehicle had reached the spot after the incident but was chased away by angry students.

Hundreds of students and locals gathered outside the university.

Many raised slogans against the Delhi Police. They also staged a dharna outside the Jamia Nagar police station.

Shezad Ahmed, a JMI student and resident of Zakir Nagar, said they were not even allowed to protest peacefully.

"We are not going to be deterred by such incidents. We will continue with our protest," he added.

Jan 31: President Ram Nath Kovind on Friday hailed the contentious Citizenship Amendment Act as "historic" in his address to joint sitting of both houses of Parliament, prompting protests by some opposition members.

He also said that debate and discussion on any issue strengthens democracy while violence during protests weaken it.

"The Citizenship Amendment Act is a historic law. It has fulfilled wishes of our founding fathers including Mahatma Gandhi," he said.

"Debate and discussions strengthen democracy, but violence during protests weaken democracy," he said without directly referring to the anti-CAA protests in the country some of which have witnessed violence.

In a reference to abrogation of Article 370, Kovind said there is happiness among people of India that people in Jammu and Kashmir and Ladakh have got rights on par with the rest of the country.

The president said Parliament has created record in the first seven months of the new government headed by Narendra Modi by enacting several landmark legislations.

"My government is taking strong steps for making this decade as India's decade and this century as India's century," he said.

New Delhi, Feb 29: India’s economy expanded at its slowest pace in more than six years in the last three months of 2019, with analysts predicting further deceleration as the global Covid 19 coronavirus outbreak stifles growth in Asia’s third-largest economy.

The gross domestic product (GDP) data released yesterday showed government spending, private investment and exports slowing down, while there is a slight upturn in consumer spending and improvement in rural demand lent support.

The quarterly figure of 4.7% growth matched the consensus in a Reuters poll of analysts but was below a revised - and greatly increased - 5.1% rate for the previous quarter.

The central bank has warned that downside risks to global growth have increased as a result of the coronavirus epidemic, the full effects of which are still unfolding.

Prime minister Narendra Modi’s government has taken several steps to bolster economic growth, including a privatisation push and increased state spending, after cutting corporate tax rates last September.

In its annual budget presented this month, the government estimated that annual economic growth in the financial year to March 31 would be 5%, its lowest for last 11 years.

Modi’s government is targeting a slight recovery in growth to 6% for 2020/21, still far below the level needed to generate jobs for millions of young Indians entering the labour market each month.

The annual GDP figure for the September quarter was ramped up from an earlier estimate of 4.5%, while the April-June reading was similarly lifted to 5.6% from 5%, data released by the Ministry of Statistics showed on Friday.

Capital Investment Drop

In the December quarter, private investment grew 5.9%, up from 5.6% in the previous quarter, while government spending rose by 11.8%, against 13.2% in the previous three months.

However, corporate capital investment contracted by 5.2% after a 4.1% decline in the previous quarter, indicating that interest rate cuts by the central bank have failed to encourage new investment. Manufacturing, meanwhile, contracted by 0.2%.

“It appears growth slowdown is not just cyclical but more entrenched with consumption secularly joining the slowdown bandwagon even as the investment story continues to languish,” said Madhavi Arora of Edelweiss Securities in Mumbai.

Many economists said that the government stimulus could take four to six quarters of time before lifting the economy and the impact of those efforts could be outweighed by the global fallout from the coronavirus epidemic that began in China.

“The coronavirus remains the critical risk as India depends on China for both demand and supply of inputs,” said Abheek Barua, chief economist at HDFC Bank.

Indian shares sank on Friday for a sixth session running, capping their worst week in more than a decade. The NSE Nifty 50 index shed 7.3% over the week, while the Sensex dropped 6.8%, the worst weekly declines since the 2008-09 financial crisis.

Separately, India’s infrastructure output rose 2.2% year on year in January, data showed on Friday.

A spike in inflation to a more than 5-1/2 year high of 7.59% in January is expected to make the RBI hold off from further cuts to interest rates for now, while keeping its monetary stance accommodative.
