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.

Amaravati, Jan 21: Telugu Desam Party president N Chandrababu Naidu and at least 17 MLAs of his party were taken in police custody late on Monday as they tried to conduct a foot march from the state assembly to nearby Mandadam village in violation of prohibitory orders.

TDP leaders started off on the march after staging a sit-in near the assembly main entrance following the suspension of 17 MLAs from the House for the day.

They were protesting the AP Decentralisation and Inclusive Development of All Regions Bill, 2020, that was passed by the assembly, enabling the establishment of three capitals for the state.

The TDP leaders were taken to the Mangalagiri police station.

Meanwhile, tensions prevailed at the Jana Sena Party headquarters at Mangalagiri as police prevented its president Pawan Kalyan from proceeding to the Amaravati region to speak to protesters fighting for the retention of only one capital for the state.

DIG Kanti Rana Tata and other senior police officials reached the Sena office and blocked the exit of Kalyan and political affairs committee chairman Nadendla Manohar, resulting in an argument.

Kalyan asked how could police impose restrictions within his own office.

Scores of Sena workers gathered outside the office even as a large posse of police was posted to thwart Kalyan and other leaders' plans.

New Delhi, Jan 19: Reacting to a tweet by ace lawyer Indira Jaising urging her to forgive the four men on death row for brutally raping that finally took her life, Nirbhaya's mother said on Saturday: "Even if God asks me, I won't forgive them."

Speaking to news agency, over the phone, the mother who had been fighting for seven long years to send her daughter's killers to the gallows, said, "...even if god comes and asks me to forgive them, I will not. People like these (Jaising) are a blot on the society."

Commenting on Jaising's tweet, she said: "Who is she to tell or suggest to me to forgive them. What relation does she have with me. I have nothing to do with such people. She can be a relative of those (the convicts) that she is having a soft corner for."

"She is an insult to women. She is running a business in the name of human rights. She is a veteran, she should give a message to the society. But she instead will go against her own kind," she added.

Earlier in the day, Jaising had requested Nirbhaya's mother to follow the example of Congress president Sonia Gandhi, who had moved for the clemency of a woman, Nalini Murugan convicted for the assassination of her husband and former Prime Minister Rajiv Gandhi.

"While I fully identify with the pain of Nirbhaya's mother I urge her to follow the example of Sonia Gandhi who forgave Nalini and said she didn't want the death penalty for her. We are with you but against death penalty," Jaising tweeted on Friday.

A Delhi Court on Friday issued fresh death warrants against the four convicts -- Akshay, Pawan, Mukesh and Vinay in the Nirbhaya gang rape and murder case.

Additional Sessions Judge (ASJ) Satish Kumar Arora fixed 1 February as the date of execution of the four death row convicts. They will be hanged at 6am.

The move came after the prosecution moved an application seeking issuance of fresh death warrants following the rejection of the mercy plea of one of the convicts Mukesh by President Ram Nath Kovind.

The 23-year-old victim was brutally gang-raped and tortured on December 16, 2012, which later led to her death.

All the six accused were arrested and charged with sexual assault and murder. One of the accused was a minor and appeared before a juvenile justice court, while another accused committed suicide in Tihar Jail.

Four of the convicts were sentenced to death by a trial court in September 2013, and the verdict was confirmed by the Delhi High Court in March 2014 and upheld by the Supreme Court in May 2017, which also dismissed their review petitions.
