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.

Jan 13: For the first time in years, the government of India’s Prime Minister Narendra Modi is playing defense. Protests have sprung up across the country against an amendment to India’s laws — which came into effect on Friday — that makes it easier for members of some religions to become citizens of India. The government claims this is simply an attempt to protect religious minorities in the Muslim-majority countries that border India; but protesters see it as the first step toward a formal repudiation of India’s constitutionally guaranteed secularism — and one that must be resisted.

Modi was re-elected prime minister last year with an enhanced majority; his hold over the country’s politics is absolute. The formal opposition is weak, discredited and disorganized. Yet, somehow, the anti-Citizenship Act protests have taken hold. No political party is behind them; they are generally arranged by student unions, neighborhood associations and the like.

Yet this aspect of their character is precisely what will worry Modi and his right-hand man, Home Minister Amit Shah. They know how to mock and delegitimize opposition parties with ruthless efficiency. Yet creating a narrative that paints large, flag-waving crowds as traitors is not quite that easy.

For that is how these protests look: large groups of young people, many carrying witty signs and the national flag. They meet and read the preamble to India’s Constitution, into which the promise of secularism was written in the 1970’s.

They carry photographs of the Constitution’s drafter, the Columbia University-trained economist and lawyer B. R. Ambedkar. These are not the mobs the government wanted. They hoped for angry Muslims rampaging through the streets of India’s cities, whom they could point to and say: “See? We must protect you from them.” But, in spite of sometimes brutal repression, the protests have largely been nonviolent.

One, in Shaheen Bagh in a Muslim-dominated sector of New Delhi, began simply as a set of local women in a square, armed with hot tea and blankets against the chill Delhi winter. It has now become the focal point of a very different sort of resistance than what the government expected. Nothing could cure the delusions of India’s Hindu middle class, trained to see India’s Muslims as dangerous threats, as effectively as a group of otherwise clearly apolitical women sipping sweet tea and sharing their fears and food with anyone who will listen.

Modi was re-elected less than a year ago; what could have changed in India since then? Not much, I suspect, in most places that voted for him and his party — particularly the vast rural hinterland of northern India. But urban India was also possibly never quite as content as electoral results suggested. India’s growth dipped below 5% in recent quarters; demand has crashed, and uncertainty about the future is widespread. Worse, the government’s response to the protests was clearly ill-judged. University campuses were attacked, in one case by the police and later by masked men almost certainly connected to the ruling party.

Protesters were harassed and detained with little cause. The courts seemed uninterested. And, slowly, anger began to grow on social media — not just on Twitter, but also on Instagram, previously the preserve of pretty bowls of salad. Instagram is the one social medium over which Modi’s party does not have a stranglehold; and it is where these protests, with their photogenic signs and flags, have found a natural home. As a result, people across urban India who would never previously have gone to a demonstration or a political rally have been slowly politicized.

India is, in fact, becoming more like a normal democracy. “Normal,” that is, for the 2020’s. Liberal democracies across the world are politically divided, often between more liberal urban centers and coasts, and angrier, “left-behind” hinterlands. Modi’s political secret was that he was that rare populist who could unite both the hopeful cities and the resentful countryside. Yet this once magic formula seems to have become ineffective. Five of India’s six largest cities are not ruled by Modi’s Bharatiya Janata Party in any case — the financial hub of Mumbai changed hands recently. The BJP has set its sights on winning state elections in Delhi in a few weeks. Which way the capital’s voters will go is uncertain. But that itself is revealing — last year, Modi swept all seven parliamentary seats in Delhi.

In the end, the Citizenship Amendment Act is now law, the BJP might manage to win Delhi, and the protests might die down as the days get unmanageably hot and state repression increases. But urban India has put Modi on notice. His days of being India’s unifier are over: From now on, like all the other populists, he will have to keep one eye on the streets of his country’s cities.

Washington, Feb 1: The Indian economy experienced some abrupt slowdown in 2019 due to turbulence in non-banking financial institutions and major reform measures such as GST and demonetisation, but it is not in a recession, IMF Managing Director Kristalina Georgieva has said.

"The Indian economy indeed has experienced an abrupt slowdown in 2019. We had to revise our growth projections, downwards to four percent for last year. We are expecting 5.8 per cent (growth rate) in 2020 and then an upward trajectory to 6.5 percent in 2021," Georgieva told a group of foreign journalists here on Friday.

"It appears that the main reason for this slowdown was the non-banking financial institutions experiencing a turbulence," she said on the eve of Union Finance Minister Nirmala Sitharaman presenting the annual budget in Parliament on Saturday.

She said India had undertaken some important reforms that over the longer term would be beneficial for the country, but they do have some short-term impact.

"For example, coming with the unified tax system, and the demonetisation that took place. These are steps that over time are beneficial, but of course they might, might be somewhat disruptive over short term," Georgieva said in response to a question.

The International Monetary Fund (IMF) Managing Director said that there is not a lot of fiscal space in India. “But we also recognise that the policies of the government on that side, on the fiscal side have been prudent. We will see how the reading of the budget, the submission of the budget goes, tomorrow,” she said.

In the medium-term, she said, the IMF remains optimistic about India. “This is why we see that upswing potential for the growth in the country,” she said.

Georgieva said that the current economic slowdown cannot be described as a recession. "No.... You're far from that. But it is a significant slowdown, not the recession," she said.

The IMF managing Director noted that the consumption in India also slowed down and that contributed to the overall slowdown in the economy. The IMF would be keen to see what India does to get relatively sound macroeconomic fundamentals to pay off in terms of better growth trajectory, she said ahead of the budget.

One thing that is important for India is that budgetary revenue have been below target. "The country knows that. The finance minister knows it. They need to increase budgetary revenue collection so they can improve their fiscal position. I said it's tight on the spending side, but I also want to stress that there is room to improve collection on the revenue side," she said.
