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.

Washington, Mar 18: Hundreds of distressed Indian students, stuck in the Philippines, are seeking help through video messages as they are unable to fly back home due to the travel restrictions imposed by India to contain the spread of the deadly novel coronavirus, according to friends and relatives of some of these students in the US.

The Indian government on Tuesday banned the entry of passengers from Afghanistan, Philippines and Malaysia to India with immediate effect amid stepped up efforts against the spread of COVID-19.

In a video message by one of these students Akhil Bala Nair, around 200 Indian students had booked their flight tickets for India in the next few days. But all of them have been cancelled due to the new policy.

Most of the students, she said, had booked their flights for March 17 and rest were schedule to travel to India on March 19 and 20. But the flights were cancelled and scores of Indian students are now stuck at the airport in Manila, Nair said in the video message sent to Prem Bhandari, head of the Jaipur Foot USA.

“It is need of the hour that the Indian government send a plane to bring these Indian students back home,” Bhandari, who in the past has worked for the cause of the Indian diaspora, and who was approached by these students told PTI.

According to these students, some 100 of them have been at the airport since Tuesday.

They all have confirmed tickets but the airport authorities are not allowing them to check in because of the new travel regulations.

While the airport authorities have asked them to go back to their respective place of residence, the students said they were unable to travel because of the absence of local taxi or shared ride services.

The students said that they are running out of time as the Philippines government has given them 72 hours time to exit the country, which started from March 16, after which the country will go into lockdown.

“This means we would not be able to travel anywhere outside Philippines after March 20,” Nair said in her message.

The students said that there are many of them who have applied for renewal of their visas and are unable to travel to India.

There are nearly 1,000 Indian students presently in Manila who are willing to travel back home, they said.

Meanwhile, the Indian Embassy in Manila, in a tweet, said that they, along with the Ministry of External Affairs, are trying to work out a solution.

“It is requested to all to kindly have patience,” the embassy said.

New Delhi, Feb 28: The Congress on Friday reacted sharply to the petition in the court seeking registration of a First Information Report against Sonia Gandhi, Rahul Gandhi and Priyanka Gandhi Vadra for alleged hate speeches. It said the petition was to save BJP leaders Pravesh Verma, Anurag Thakur and Kapil Mishra, referring to the trio as "PAK".

Congress leader Jaiveer Shergil told news agency, "It is political interest litigation to hide the failure of the government and to put a lid on the BJP's involvement in fuelling the fire in Delhi riots.

"This is to hide and save BJP's PAK -- Pravesh, Anurag and Kapil," said Shergil.

The BJP has two parameters, the laws for the common man and citizens of the country are different from those for the BJP leaders, added Mr Shergil.

The Delhi High Court on Friday issued notices on a petition for the registration of an FIR against Sonia Gandhi, Rahul Gandhi, Priyanka Gandhi Vadra and others on charges of delivering hate speeches.

Congress said that the PIL was politically motivated and the inaction on the hate speeches made by the BJP leaders, which led to the riots, was shocking.

"When there are 48 cases registered, why three cases against the BJP leaders are not registered," asked Mr Shergil.

A Bench of Chief Justice DN Patel sought responses from the Central and Delhi governments apart from Delhi Police on a petition filed by Lawyers Voice. The matter will again be heard on April 13.

The petition also sought a case against Aam Aadmi Party leaders Manish Sisodia and Amanatullah Khan, All India Majlis-e-Ittehadul Muslimeen leaders Akbaruddin Owaisi and Waris Pathan, and lawyer Mehmood Paracha.

"Issue directions to constitute an SIT to look into these hate speeches and take appropriate action. Issue direction to register an FIR against those named in the petition," the petition said.

New Delhi, Feb 13: Arvind Kejriwal wrote to Delhi Lieutenant Governor Anil Baijal on Wednesday, staking claim to form the government in the national capital, sources said, while hinting that the AAP might not invite senior leaders and chief ministers of other parties for the oath-taking ceremony.

The sources said it was the formal process by the AAP chief, who was elected as the legislature party leader earlier in the day, to stake claim for forming the new government.

Kejriwal, who returned to power in Delhi with a stunning poll victory on Tuesday, will take oath as chief minister for the third consecutive time on February 16.

While the oath-taking ceremony will be open to the public, the Aam Aadmi Party (AAP) was considering not inviting leaders and chief ministers of other parties as it did not wish to be seen as a "confrontationist" against the BJP-led Centre, the sources said.

They, however, added that the party was yet to take a decision on it.

The AAP has planned mobilisation of people for the mega event and all the newly-elected MLAs of the party have been asked to ensure huge participation from their constituencies.

"I request the people of Delhi to attend the oath-taking ceremony of the chief minister at the Ramlila Maidan in large numbers," senior AAP leader Manish Sisodia told reporters, adding that the ceremony will start at 10 am.

The AAP won 62 seats in the 70-member Delhi Assembly, while the Bharatiya Janata Party (BJP) bagged the remaining eight seats. The Congress drew a blank for the second consecutive time in the Delhi polls.
