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.

Mangaluru, Apr 10: In a profound act of generosity and faith, senior businessman and Congress leader Inayath Ali has donated 1.5 acres of prime land in the heart of Mangaluru for the construction of a Haj Bhavan. The land—strategically located just 1.5 kilometres from the Mangaluru International Airport and adjacent to a major road—is estimated to be worth over ₹8 crore.

The donation, made earlier this week, has captured public attention not just for its magnitude, but for the spirit behind it. At a time when the nation is engaged in an intense debate over the recently passed Waqf (Amendment) Act, this selfless contribution opens a new chapter in understanding the true essence of waqf.

According to sources, the upcoming Haj Bhavan will house a mosque, and offer training and orientation services for pilgrims travelling to Mecca—providing both spiritual and logistical support to hundreds of Hajj aspirants from the region.

What sets this gesture apart is the absolute surrender of rights by Inayath Ali. Despite not being a high-profile industrialist or real estate mogul, he has forfeited all claims over the land. Under Islamic waqf principles, once a property is donated, neither the donor nor their descendants can reclaim or profit from it—making it a permanent endowment for the community.

This timely development is sparking fresh conversations about the spiritual and charitable foundations of waqf, especially amid allegations and controversies surrounding waqf properties in various parts of the country. Critics often claim that waqf lands have expanded disproportionately or were historically acquired from other communities. Inayath Ali’s donation stands as a counter-narrative—one that reflects the voluntary, sacred, and socially uplifting nature of such endowments.

For generations, Muslims—from wealthy businesspersons to humble individuals—have donated land and property to build mosques, madrasas, orphanages, and cemeteries. Elders from the coastal Muslim community affirm that such acts are not merely cultural traditions but are deeply rooted in the belief that sadaqah jariyah (a continuing charity) benefits the soul in both this world and the hereafter.

Inayath Ali’s contribution, thus, is not just a donation of land—it is a message of unity, service, and spiritual vision for generations to come.

Bengaluru, Apr 11: In a significant development, the Karnataka Cabinet on Friday formally accepted the controversial Socio-Economic and Educational Survey, popularly known as the caste census, nearly a decade after it was conducted. The report will be taken up for detailed discussion in a special Cabinet meeting on April 17.

The survey was originally carried out in 2015 by the Karnataka State Commission for Backward Classes under the chairmanship of H. Kantharaj, and finalised in February 2024 by his successor, K. Jayaprakash Hegde. The long-awaited report—comprising 50 volumes of detailed caste- and community-related data—was placed before the Cabinet in a sealed cover, which was opened during Friday’s meeting.

Backward Classes Welfare Minister Shivaraj Tangadagi, while briefing the media, said the report would now be distributed to all Cabinet ministers so they could examine its findings ahead of the April 17 meeting. Though the government did not disclose the contents of the report, it sought to validate the survey’s legitimacy by presenting statistical data.

“As per the 2011 Census, Karnataka’s population was 6.11 crore. By 2015, when the survey was conducted, it had grown to an estimated 6.35 crore. The survey covered 5.98 crore people—a coverage of 94.17 percent,” Tangadagi said.
He added that only 37 lakh people, or 5.83 percent, were left out of the enumeration process.

Highlighting the scale of the operation, the minister said 1.6 lakh government officials participated in the survey. An expert committee was constituted, which developed 54 criteria to guide the data collection. The state government also engaged Bharat Electronics Limited (BEL) to manage the survey data under a ₹43 crore agreement, with the total expenditure reaching ₹165 crore.

Law and Parliamentary Affairs Minister H. K. Patil announced that a special Cabinet session will be held on April 17 to deliberate on the report's contents. When asked about concerns over the completeness of the data, Patil responded, “Even in the national Census, some people are left out. A 94 percent coverage is a very significant achievement.”

The caste census remains a politically sensitive issue in Karnataka. Dominant communities such as the Lingayats and Vokkaligas have questioned the methodology of the 2015 survey, alleging undercounting. In contrast, Other Backward Classes (OBCs) and SC/ST groups have welcomed the report, arguing that it sheds light on social realities long ignored.

The Congress party had pledged to act on the caste census in its manifestos for the 2023 Karnataka Assembly elections and the 2024 Lok Sabha polls. National party leader Rahul Gandhi has also been advocating for a nationwide caste census.

The Cabinet’s acceptance of the report comes just days after Chief Minister Siddaramaiah’s meeting with Rahul Gandhi in New Delhi, and the Congress Working Committee’s session in Ahmedabad.

Six Ministers Skip Cabinet Meeting

At least six ministers were notably absent from Friday’s Cabinet meeting. These included:

    S. S. Mallikarjun and Laxmi Hebbalkar (both Lingayats)

    M. C. Sudhakar and K. Venkatesh (both Vokkaligas)

    R. B. Timmapur (SC)

    Madhu Bangarappa (Idiga community)

However, Minister Patil clarified that despite their absence, all ministers have endorsed the Cabinet’s collective decision, regardless of caste or community affiliations.

Mangaluru, Apr 7: A price storm is brewing in Mangaluru’s hotel and restaurant industry. Faced with skyrocketing raw material costs and mounting overheads, hoteliers are preparing to hike food prices by up to 10% within a month — a move that could hit the pockets of thousands of diners across Dakshina Kannada.

From milk and oil to LPG and staples like rice and toor dal, prices have surged, pushing both vegetarian and non-vegetarian establishments to the brink. Over 65% of hotels operate in rented spaces, and labour shortages are adding fuel to the fire.

Swarna Sunder of Dinki Dine says running a hotel without burdening customers is becoming near-impossible. “Costs are rising daily. We’re trying to strike a balance, but a hike is inevitable,” he said, calling Mangaluru a highly price-sensitive market.

Industry leaders, including the Dakshina Kannada Hotel Owners Association, are expected to meet soon to formalize the revision.

Meanwhile, hoteliers blame "unhealthy competition" for further disrupting the sector. “Some serve unlimited fish meals under ₹60 — it’s unsustainable and unfair,” said a hotelier, adding that such practices are forcing smaller eateries to shut shop.

Chandrahas Shetty, president of the district association, confirmed that rising input costs have left them with little choice but to revise menus.
