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.

Udupi: A 40-year-old NRI from Udupi has reportedly lost more than Rs 12.25 lakh in an online investment scam operated through Telegram.

According to a complaint filed at the CEN police station, Leo Jerome Mendonsa, who has been working in Dubai for the past 15 years in computer accessories sales, maintains NRI accounts in Karkala and Nitte.

On November 12, 2025, Mendonsa was added to a Telegram group called Instaflow Earnings by unknown individuals. Users identified as Priya and Dipannita persuaded him to invest in “Revenue Tasks.” Initially, Mendonsa transferred Rs 1,100 multiple times and received the promised returns, encouraging him to continue.

On November 14, another user, Nishmitha Shetty, directed him to register on a website, digitvisionuoce.cc, and invest Rs 4 lakh in various shares. Over the next few days, he made multiple transfers totaling Rs 12,25,000, including Rs 50,000 via Google Pay, believing the scheme was legitimate.

After receiving the money, the alleged handlers stopped responding, and neither the invested amount nor the promised profits were returned.

The CEN police have registered a case under Sections 66(C) and 66(D) of the IT Act and Section 318(4) of the Bharatiya Nyaya Sanhita (BNS), and investigations are ongoing.

Bengaluru, Nov 26: Karnataka is taking its first concrete steps towards lifting a three-decade-old ban on student elections in colleges and universities. Deputy Chief Minister D.K. Shivakumar announced Wednesday that the state government will form a small committee to study the reintroduction of campus polls, a practice halted in 1989 following incidents of violence.

Speaking at a 'Constitution Day' event organised by the Karnataka Congress, Mr. Shivakumar underscored the move's aim: nurturing new political leadership from the grassroots.

"Recently, (Leader of the Opposition in Lok Sabha) Rahul Gandhi wrote a letter to me and Chief Minister (Siddaramaiah) asking us to think about restarting student elections," Shivakumar stated. "I'm announcing today that we'll form a small committee and seek a report on this."

Student elections were banned in Karnataka in 1989, largely due to concerns over violence and the infiltration of political party affiliates into campus life. The ban effectively extinguished vibrant student bodies and the pipeline of young leaders they often produced.

Mr. Shivakumar, who also serves as the Karnataka Congress president, said that former student leaders will be consulted to "study the pros and cons" of the re-introduction.

Acknowledging the history of the ban, he added, "There were many criminal activities taking place back then. We’ll see how we can conduct (student) elections by regulating such criminal activities."

The Deputy CM reminisced about his own journey, which began on campus. He recalled his political activism at Sri Jagadguru Renukacharya College leading to his first Assembly ticket in 1985 at the age of 23. "That's how student leadership was at the time. Such leadership has gone today. College elections have stopped," he lamented, adding that for many, college elections were "like a big movement" where leaders were forged.

The move, driven by the Congress high command's push to cultivate young talent, will face scrutiny from academics and university authorities who have, in the past, expressed concern that the return of polls could disrupt the peaceful academic environment and turn campuses into political battlegrounds.

New Delhi: Karnataka chief minister Siddaramaiah and deputy CM DK Shivakumar on Saturday put up a dramatic display of unity at a closely watched joint press briefing, firmly dismissing weeks of speculation about a power-sharing tussle within the Congress. With the high command nudging both leaders to sit together and settle the dust, the meeting became a political spectacle, ending with the duo declaring that there was “no confusion, no differences.”

Calling the reports of a rift “manufactured confusion,” Siddaramaiah said the talks had gone smoothly, even joking about their breakfast. “Breakfast was very good. All three of us enjoyed it,” he said. “We want to end this confusion once and for all. For local elections and for 2028, our mission is clear — Congress must return to power. There is no difference between me and DKS, not now, not before.”

He blamed the media for fuelling rumours and reiterated absolute adherence to the party leadership. “From tomorrow, let there be no confusion. What the high command says, we will follow.”

Siddaramaiah also assured that the Assembly session starting December 8 would run smoothly and vowed that Congress would take on the BJP and JD(S) “together.”

Shivakumar echoed the chief minister word for word, stressing loyalty and discipline. “People have given us a massive mandate. It is our duty to deliver,” he said. “This government was formed under Siddaramaiah’s leadership. We both have complete trust in the high command. If they tell me to wait, I will wait.”

He added that the two leaders had discussed strategy for the 2028 Assembly elections. “Whatever the CM says, I agree. We are loyal soldiers of the party. The party may be facing challenges nationally, but we will keep it strong in Karnataka.”

Shivakumar also said Siddaramaiah would soon visit his home for lunch or dinner — another symbolic gesture meant to underline their unity.

Both leaders later posted on social media describing the breakfast meeting as “productive” and focused on “Karnataka’s priorities.”

The BJP, however, rejected the show of camaraderie as “pure bunkum,” accusing Congress of trying to paper over an internal power struggle. But Siddaramaiah and Shivakumar insisted their united front would continue — and that there was “no confusion” within the state leadership.
