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.

Feb 29: The "Dadi of Shaheenbagh" on Friday said that Prime Minister Narendra Modi does not understand the pain of losing children, as speakers at an anti-CAA rally here called on protesters to maintain peace and not give in to any provocation.

Tushar Gandhi, the great-grandson of Mahatma Gandhi, said that the battle is not for a day or two, but the protesters will have to be prepared to continue it for years to come.

Asma Khatoon, who has earned fame as the "Dadi of Shaheenbagh" in Delhi, asked how can a person take care of the whole country when he cannot maintain his own family.

"He would have realised how it feels to lose a child if he had his own children," she told a gathering at the Park Circus Maidan, which is being termed as the Shaheenbagh of Kolkata with women holding a sit-in for the last 53 days to protest the Citizenship (Amendment) Act, proposed nationwide NRC, and the NPR.

The death toll Delhi's communal violence has gone up to 42.

She said it is not biryani that has attracted women to the protest at Shaheen bagh while holding that such vilification campaigns will have no effect on the agitation.

State BJP president Dilip Ghosh has claimed that "uneducated men and women" are protesting at Delhi's Shaheen Bagh and Kolkata's Park Circus as they get money and biryani purchased with foreign funds.

"Home Minister Amit Shah has called 20 protesters to meet him, but I want to tell him that we are one lakh and I want him to mention the place where he wants us to go for the meeting," she said.

Tushar Gandhi said, "People should stay united and not give in to any provocation," he said.

Gandhi said that the people of West Bengal are lucky to have Mamata Banerjee as their chief minister.

"They will try to break her also and it is necessary that you continue to give her support," he said.

Gandhi claimed that no one can harm a country where its mothers and sisters come out to save it.

He claimed that the CAA is not about Hindus or Muslims, but will really affect the poor people, who will be made to run around to get their papers instead of earning for their basic and daily needs.

"It's a dichotomous government that we have at the Centre. On the one hand, they want us to provide documents to prove our citizenship, while on the other they refuse to accept the papers that one produces before it for the purpose," he said.

He claimed that the government is forcing its people to resort to lies and declare that they are political refugees from countries like Bangladesh and Pakistan.

Gandhi claimed that time and again documents with the government like electoral rolls and land documents have been used to identify people of certain communities during riots.

"So it is dangerous to give too much information to the government," he said.

He called on the people to have faith in non-violence and asked them to maintain peace and harmony.

B R Ambedkar's great-grandson Rajratna Ambedkar claimed that it is the Adivasis who will also be affected by the CAA.

"I want to tell Modi and Shah that the country runs on the Constitution by Ambedkar and not M S Golwalkar (of RSS)," he said, adding that because of the rights conferred on people by the Constitution, those backward people who did not have the right to sit on a bullock cart are now flying jet planes.

He said that Modi and Shah committed an error by enacting the CAA as it has turned the people of the country into Indians only, instead of Hindus, Muslims, Christians or Sikhs.

"Every machinery of the country has been taken control of by the RSS. If one Modi or one Shah goes, they will bring in several more Modi or Shah," he said.

Geneva, Jul 11: The World Health Organization said Friday that it is still possible to bring coronavirus outbreaks under control, even though case numbers have more than doubled in the past six weeks.

WHO chief Tedros Adhanom Ghebreyesus said the examples of Italy, Spain, South Korea and India's biggest slum showed that however bad a outbreak was, the virus could still be reined in through aggressive action.

"In the last six weeks cases have more than doubled," Tedros told a virtual press conference in Geneva.

However, "there are many examples from around the world that have shown that even if the outbreak is very intense, it can still be brought back under control," said Tedros.

"And some of these examples are Italy, Spain and South Korea, and even in Dharavi -- a densely packed area in the megacity of Mumbai -- a strong focus on community engagement and the basics of testing, tracing, isolating and treating all those that are sick is key to breaking the chains of transmission and suppressing the virus."

The novel coronavirus has killed at least 555,000 people worldwide since the outbreak emerged in China last December, according to a tally from official sources compiled by AFP on Friday.

Nearly 12.3 million cases have been registered in 196 countries and territories.

"Across all walks of life, we are all being tested to the limit," Tedros said, "from countries where there is exponential growth, to places that are loosening restrictions and now starting to see cases rise.

"Only aggressive action combined with national unity and global solidarity can turn this pandemic around."
