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, Jan 15: The Delhi government Wednesday told the high court that execution of the death row convicts in the Nirbhaya gangrape and murder case will not take place on January 22 as a mercy plea has been filed by one of them.

The four convicts -- Vinay Sharma (26), Mukesh Kumar (32), Akshay Kumar Singh (31) and Pawan Gupta (25) -- are to be hanged on January 22 at 7 am in Tihar jail. A Delhi court had issued their death warrants on January 7.

Justices Manmohan and Sangita Dhingra Sehgal were told by the Delhi government and the Centre that the petition filed by convict Mukesh, challenging his death warrant, was premature.

The Delhi government and the prison authorities informed the court that under the rules, it will have to wait for the mercy plea to be decided before executing the death warrant.

They also said that none of the four convicts can be executed on January 22 unless the present mercy plea is decided.

The Supreme Court had on Tuesday dismissed the curative pleas of Mukesh and Vinay.

The mercy plea hearing began Wednesday morning and will continue in the afternoon.

Kashmir, Jan 9: US Ambassador to India Kenneth I Juster along with envoys from 15 other countries arrived in Srinagar on a two-day visit to Jammu and Kashmir on Thursday, the first visit by diplomats since the abrogation of the erstwhile state's special status in August last year.

The Delhi-based envoys arrived in Srinagar by a special chartered flight at Srinagar's technical airport where top officials from the newly carved out union territory received them, officials said.

Later in the day, they would be going to Jammu, the winter capital of the newly created Union Territory, for an overnight stay. They will meet Lt Governor G C Murmu as well as civil society members, they said.

Besides the US, the delegation will include diplomats from Bangladesh, Vietnam, Norway, Maldives, South Korea, Morocco, and Nigeria, among others.

Brazil's envoy Andre Aranha Correa do Lago was also scheduled to visit Jammu and Kashmir. However, he backed out because of his preoccupation here, the officials said on Wednesday.

Envoys from the European Union (EU) countries are understood to have conveyed that they will visit the union territory on a different date and are also believed to have stressed on meeting the three former chief ministers -- Farooq Abdullah, Omar Abdullah and Mehbooba Mufti -- who are under detention.

Officials said envoys of several countries had requested the government for a visit to Kashmir to get a first-hand account of the situation in the Valley following the August 5 decision to abrogate provisions of Article 370 and bifurcate it into two union territories, Jammu and Kashmir, and Ladakh.

This is the second visit of a foreign delegation to Jammu and Kashmir since August 5. Earlier, Delhi-based think tank International Institute for Non-Aligned Studies, a Delhi-based think tank took 23 EU MPs on a two-day visit to assess the situation in the union territory.

The government had distanced itself from the visit with Minister of State for Home G Kishan Reddy informing Parliament that the European parliamentarians were on a "private visit".

New Delhi, June 22: Former Prime Minister Manmohan Singh on Monday asked Prime Minister Narendra Modi to be “mindful of the implication of his words” as a controversy raged over his “no intrusion” remark about the violent face-off with Chinese troops in the Galwan Valley.

“The Prime Minister must always be mindful of the implications of his words and declarations on our Nation’s security as also strategic and territorial interests,” Singh said in a statement here as Chinese media welcomed Modi’s ‘no intrusion’  remarks contending that it may lead to a de-escalation of tensions between China and India.

Congress has been maintaining that Modi’s assertions at Friday’s all-party meeting that neither was there any intrusion nor was any Indian post captured ran counter to the statements made by the Indian Army and the External Affairs Ministry.

Singh said the prime minister cannot allow his words to be used by China as a vindication of its position and all organs of the government should work together to tackle this crisis and prevent it from escalating further.

“We remind the Government that disinformation is no substitute for diplomacy or decisive leadership. The truth cannot be suppressed by having pliant allies spout comforting but false statements,” the former prime minister said.

Singh said the prime minister and the government should rise to the occasion to ensure justice for Colonel B Santosh and the army jawans who made the supreme sacrifice and resolutely defended the nation’s territorial integrity.

“To do any less would be a historic betrayal of the people’s faith,” the former prime minister said.

“At this moment, we stand at historic crossroads. Our Government’s decisions and actions will have serious bearings on how the future generations perceive us,” Singh said.

Singh said China was brazenly and illegally seeking to claim parts of Indian territory such as the Galwan Valley and the Pangong Tso Lake by committing multiple incursions between April 2020 till date.  

“We cannot and will not be cowed down by threats and intimidation nor permit a compromise with our territorial integrity,” said Singh. 

The former prime minister said this was a moment where “we must stand together as a nation and be united in our response to this brazen threat.”
