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.

Mar 21: India’s economy, already in the grip of a slowdown, is in for more pain after Prime Minister Narendra Modi appealed to citizens to stay at and work from home to curb the coronavirus outbreak.

The services sector, which accounts for about 55% of India’s gross domestic product, is poised to be the worst hit after Modi, in a late evening address on Thursday, urged citizens to go on a self-imposed curfew for a day and private companies to allow employees to work from home for longer. In the country’s vast informal sector, social-distancing measures could mean a dent to productivity and consumption because of job or pay losses.

“The impact of a partial lock-down or social distancing will be significant,” said Rahul Bajoria, a senior economist at Barclays Plc in Mumbai. “If there’s a widespread community outbreak, GDP could fall as low as 3.5% in the year starting April 1.”

Shrinking output may limit growth in an economy that’s already set to expand at an 11-year low of 5% in the current year to March 31. Before the virus outbreak, India had forecast growth to recover to 6%-6.5% in the next fiscal year. S&P Global Ratings and Fitch Ratings have already slashed their growth forecast by 50 basis points.

“The current social-distancing measures will severely impact airlines, hotels, malls, multiplexes, restaurants and retailers,” according to analysts at Crisil Ltd., the local unit of S&P Global. “Lower footfalls and occupancies, decline in business volume and sub-optimal operating efficiencies will impact cash flows of companies in these sectors,” wrote the analysts led by Chief Economist Dharmakirti Joshi.

The government will try to announce a relief package for virus-affected sectors as early as possible, Finance Minister Nirmala Sitharaman said Friday.

In a televised address, Modi advised all citizens to stay at home for a day on March 22, as he sought to stem the spread of the coronavirus -- cases of which are relatively low in India at about 200, compared with more than 200,000 infected people globally. His government also barred incoming flights for a week from that day, joining a growing list of countries effectively sealing their borders.

What Bloomberg’s Economists Say

We had only earlier this week lowered our GDP outlook to consider the direct impact of the local outbreak as confirmed virus cases exceeded 100 as of March 15 and the federal and state governments announced social distancing measures that have already started to crimp economic activity. We are now revising down our GDP estimate for 4Q fiscal 2020 to 3.3%, from our 3.5%.

“Consumption being the biggest component of GDP, a lock-down is bound to have a big impact on the economy,” said Devendra Kumar Pant, chief economist at India Ratings and Research, the local unit of Fitch. “Modeling uncertainty in any system will be very difficult, but one can say the slowdown could deepen or prolong further.”

Work From Home

While companies, including billionaire Mukesh Ambani-controlled Reliance Industries Ltd., are asking employees to work from home, the option isn’t feasible in India’s vast informal sector.

“The option to work remotely simply won’t exist for most,” said Shilan Shah, an economist with Capital Economics Pte. in Singapore.

As many households don’t have savings buffers, the government would probably have to back this up with large-scale cash handouts that reach the poorest, he said.

Work from home is posing implementation challenges for the manufacturing sector where workers are required to be physically present at the production sites. The services sector, such as banking and information technology, also needs employees to be present in offices as confidential data is used, according to industry group Federation of Indian Chambers of Commerce and Industry.

New Delhi, Jan 10: The Supreme Court while hearing petitions challenging restrictions in Jammu and Kashmir on Friday stated that the right to access the internet is a fundamental right under Article 19 of the Constitution of India.

"It is no doubt that freedom of speech is an essential tool in a democratic setup. The freedom of Internet access is a fundamental right under Article 19(1)(a) of the Constitution," a two-judge bench headed by Justice N V Ramana stated while reading out the judgment.

The top court said that Kashmir has seen a lot of violence and that it will try to maintain a balance between human rights and freedoms with the issue of security.

It also directed the Jammu and Kashmir administration to review the restrictive orders imposed in the region within a week. “The citizens should be provided highest security and liberty,” the apex court added.

The top court made observations and issued directions while pronouncing the verdict on a number of petitions challenging the restrictions and internet blockade imposed in Jammu and Kashmir after the abrogation of Article 370 in August last year.

The Supreme Court had on November 27 reserved the judgment on a batch of petitions challenging restrictions imposed on communication, media and telephone services in Jammu and Kashmir pursuant to revocation of Article 370.

The court heard the petitions filed by various petitioners including Congress leader Ghulam Nabi Azad and Kashmir Times editor Anuradha Bhasin.

The petitions were filed after the central government scrapped Article 370 in August and bifurcated Jammu and Kashmir into two Union Territories -- Jammu and Kashmir and Ladakh. Following this, phone lines and the internet were blocked in the region.

The government had, however, contended that it has progressively eased restrictions.
