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 district transformed into a sea of saffron and celebration on Friday, November 28, as Prime Minister Narendra Modi’s roadshow swept through the coastal temple town. Thousands of residents lined the streets, turning the event into a vibrant public spectacle filled with cheers, flags, and festive energy.

The procession route—from the helipad to the historic Sri Krishna Math—was decked with buntings, saffron flags, and multilayered security barricades. One of the district’s largest-ever security deployments was put in place for the high-profile visit, with over 3,000 police personnel on duty. The arrangement included ten SPs, 27 DSPs, 49 inspectors, 127 sub-inspectors, 232 assistant sub-inspectors, 1,608 constables, and 39 women staff.

Six platoons of the Karnataka State Reserve Police, six Quick Response Teams, bomb detection units, and dog squads were stationed across Udupi. Enhanced surveillance covered Adi Udupi, Bannanje bus stand, and the Sri Krishna Math parking zone, with combing operations carried out along the roadshow corridor.

At the 800-year-old Sri Krishna Math, preparations reached a ceremonial peak. Paryaya Puttige Math seer Sugunendra Teertha Swamiji said the Prime Minister would take part in the Laksha Kantha Geetha Parayana, a mass chanting of the Bhagavad Gita by one lakh devotees, and inaugurate the new Suvarna Teertha Mantapa.

“He will first offer floral tributes to saint-poet Kanakadasa and then unveil the golden covering over the Kanakana Kindi,” the seer said.

The Prime Minister will also receive a Poorna Kumbha welcome and have darshan of Lord Sri Krishna, Mukhyaprana Devaru, and the Suvarna Paduke. Union Minister Pralhad Joshi, Karnataka Governor Thaawarchand Gehlot, Minister Bairathi Suresh, Dharmadhikari D. Veerendra Heggade, and seers from the Ashta Maths are expected to join the ceremony.

Ahead of his arrival, the Prime Minister posted on X that he felt “honoured” to attend the spiritually significant gathering. “This is a special occasion that brings together people from different sections of society for a recital of the Gita. This Matha has a very special significance in our cultural life,” he wrote, noting the institution’s long-standing legacy rooted in the teachings of Sri Madhvacharya.

Mangaluru, Nov 26: Assembly Speaker and local MLA U.T. Khader has initiated a high-level push to resolve one of Mangaluru’s longest-standing traffic headaches: the narrow, high-density stretch of National Highway-66 between Nanthoor and Talapady.

He announced on Tuesday that a formal proposal has been submitted to the Union Ministry of Road Transport and Highways (MoRTH) seeking approval to prepare a Detailed Project Report (DPR) for the widening of this crucial corridor.

The plan specifically aims to expand the existing 45-meter road width to a full 60 meters, coupled with the construction of dedicated service roads. Khader highlighted that land for a 60-meter highway was originally acquired during the initial four-laning project, but only 45 meters were developed, leading to a perpetual bottleneck.

"With vehicle density rising sharply, the expansion has become unavoidable," Khader stated, stressing that the upgrade is essential for ensuring smoother traffic flow and improving safety at the city's main entry and exit points.

The stretch between Nanthoor and Talapady is a vital link on the busy Kochi-Panvel coastal highway and connects to major city junctions. The move to utilize the previously acquired land for the full 60-meter width is seen as a necessary measure to catch up with the region's rapid vehicular growth and prevent further traffic gridlocks.

indigocrisis.jpg

Angry outbursts, long queues, and desperate appeals filled airports across India today as IndiGo grappled with a severe operational breakdown. Hundreds of flights have been cancelled or delayed, leaving thousands of passengers stranded through the night and forcing many to spend long hours at helpdesks.

Social media was flooded with videos of fliers pleading for assistance, accusing the airline of misleading updates, and demanding accommodation after being stuck for 10 to 12 hours at airports such as Hyderabad and Bengaluru.

What Triggered the Meltdown?

IndiGo has attributed the widespread disruption to “a multitude of unforeseen operational challenges.” These include:

•    Minor technology glitches
•    Winter-season schedule adjustments
•    Bad weather
•    Congestion in the aviation network
•    New crew rostering rules (Flight Duty Time Limitations or FDTL)

Among these, the most disruptive has been the implementation of the updated FDTL norms introduced by the Directorate General of Civil Aviation (DGCA) in January 2024.

These rules were designed to reduce pilot fatigue and improve passenger safety. Key changes include:

•    Longer weekly rest periods for flight crew
•    A revised definition of “night,” extending it by an extra hour
•    Tighter caps on flight duty timing and night landings
•    Cutting night shifts for pilots and crew from six per roster cycle to just two

Once these norms became fully enforceable, airlines were required to overhaul rosters well in advance. For IndiGo, this triggered a sudden shortage of crew available for duty, leading to cascading delays and cancellations.

Why IndiGo Was Hit the Hardest

IndiGo is India’s largest airline by a wide margin, operating over 2,200 flights daily. That’s roughly double the number operated by Air India.

When an airline of this size experiences even a 10–20% disruption, it translates to 200–400 flights being delayed or grounded — producing massive spillover effects across the country.

IndiGo also relies heavily on high-frequency overnight operations, a model typical of low-cost carriers that aim to maximise aircraft utilisation and reduce downtime. The stricter FDTL norms clash with these overnight-heavy schedules, forcing the airline to pull back services.

Aviation bodies have also criticised IndiGo’s preparedness. The Airline Pilots' Association of India (ALPA) said airlines were given a two-year window to plan for the new rules but “started preparing rather late.” IndiGo, it said, failed to rebuild crew rosters 15 days in advance as required.

The Federation of Indian Pilots (FIP) went further, calling the crisis the result of IndiGo’s “prolonged and unorthodox lean manpower strategy,” and alleging that the airline adopted a hiring freeze even as it knew the new rules would require more careful staffing.

How Many Flights Are Affected?

In the past 48 hours, over 300 flights have been cancelled. At least 100 more are expected to be cancelled today.

City-wise impact:

•    Hyderabad: 33 expected cancellations; several fliers stranded overnight
•    Bengaluru: over 70 expected cancellations
•    Delhi, Mumbai, Chennai, Kolkata: widespread delays and missed connections

Passengers shared distressing accounts online.

One customer at Hyderabad airport said they waited from 6 PM to 9 AM with “no action taken” regarding their delayed Pune flight. Another said IndiGo repeatedly told them the crew was “arriving soon,” only for the delay to stretch over 12 hours.

IndiGo has apologised for the disruption and promised that operations will stabilise within 48 hours, adding that “calibrated adjustments” are being made to contain the chaos.

What Should Passengers Do Now?

For those flying in the next few days, especially with IndiGo, here are key precautions:

1. Keep Checking Flight Status
Monitor your flight closely before leaving for the airport, as delays may be announced last-minute.

2. Arrive Early
Expect long queues at counters and security due to crowding and rescheduling.

3. Carry Essentials
Pack snacks, water, basic medicines, chargers, and items for children or senior citizens. Extended waiting times should be anticipated.

4. Use Flexible Booking Options
If you booked tickets with a free-date-change or cancellation option, consider using them.
If you haven’t booked yet, prefer refundable or flexible fares, or even consider alternate airlines.

5. Follow IndiGo’s Updates
Keep an eye on IndiGo’s official social media channels and contact customer support for rebooking and refund queries.

What Needs to Change?

Pilot groups have raised concerns not just about staffing but also the planning practices behind it.
The Federation of Indian Pilots accused IndiGo of:

•    Imposing an unexplained hiring freeze despite knowing the FDTL changes were coming
•    Entering non-poaching agreements that limited talent movement
•    Keeping pilot pay frozen
•    Underestimating the need to restructure operations in advance

They have urged DGCA to approve seasonal schedules only after airlines prove they have adequate pilot strength under the new norms.

ALPA also warned that some airlines might be using the delays as an “immature pressure tactic” to push DGCA for relaxations in the new rules — which, if granted, could compromise the very safety standards the norms were meant to protect.

Both pilot bodies stressed that no exemption should dilute safety, and any deviations should be based solely on scientific risk assessment.

Is a Solution in Sight?

While IndiGo says normalcy will return within two days, aviation experts believe that fully stabilising operations could take longer, depending on how quickly the airline can:
•    Re-align rosters
•    Mobilise rested crew
•    Boost staffing
•    Adjust its winter schedule to match regulatory requirements
Passengers are advised to remain prepared for continued delays over the next few days as the airline works through its backlog.
