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.

Bengaluru: In a boost to the ruling Congress in Karnataka, the party on Saturday swept the by-polls to three Assembly segments, causing a major setback to the BJP-JD(S) alliance in the state.

The Congress has retained Sandur, the seat considered to be its strong hold, and has also bagged Shiggaon and Channapatna segments, which were earlier held by BJP and JD(S) respectively.

The November 13 by-polls to Sandur, Shiggaon and Channapatna Assembly segments had witnessed a fierce fight between the ruling Congress and a combative BJP-JD(S) alliance.

The by-polls to Sandur, Shiggaon and Channapatna were necessitated as the seats fell vacant following the election of their respective representatives -- E Tukaram of Congress, former CM Basavaraj Bommai of BJP, and Union Minister Kumaraswamy of JD(S) to Lok Sabha in May elections.

The by-polls witnessed a straight fight between the ruling Congress and BJP in Sandur and Shiggaon segments, while in Channapatna, JD(S) which is part of the NDA alliance took on the grand old party.

Congress' C P Yogeeshwara won the Channapatna segment, defeating JD(S) candidate and Kumaraswamy's son Nikhil Kumaraswamy, by a margin of 25,413 votes.

Former CM Basavaraj Bommai's son Bharath Bommai of BJP faced defeat against Congress' Yasir Ahmed Khan Pathan in Shiggaon Assembly segment by a margin of 13,448 votes.

In Sandur, Congress candidate E Annapoorna, the wife of Bellary MP E Tukaram, won the seat vacated by her husband, by a margin of 9,649 votes.

Congress' win in the by-poll is seen as an endorsement of both Chief Minister Siddaramaiah and his deputy D K Shivakumar's leadership, and the government's programmes, especially the five guarantee schemes.

Nikhil Kumaraswamy and Bharath Bommai, the third generation of Gowda and Bommai family respectively, who contested this bypolls, have lost. Their fathers and grandfathers had served as Karnataka's Chief Ministers in the past.

While for Bharath Bommai this was his electoral debut, for Nikhil it was his third electoral loss.

Among the three segments, Channapatna was considered to be a high profile battle, where the contest was between C P Yogeeshwara and actor-turned-politician Nikhil Kumaraswamy.

A five-time MLA from the segment and a former Minister, Yogeeshwara had joined the Congress after quitting BJP ahead of nomination.

There were plans to field Yogeeshwara on a JD(S) ticket, but he was not interested in it, and instead wanted Kumaraswamy to support him as BJP candidate. This was not acceptable to Kumaraswamy and his party, following which Yogeeshwara jumped ship.

However, Kumaraswamy had subsequently said he had agreed to Yogeeshwara contesting from BJP, and despite that he jumped ship to Congress, under the influence of Deputy Chief Minister D K Shivakumar and his brother and former MP D K Suresh.

Nikhil had faced defeat in 2019 Lok Sabha and 2023 Assembly polls. It is seen as a setback for Kumaraswamy too, as he could not ensure son's win from the Channapatna, the seat he had twice represented in the past.

Congress' win is crucial for Shivakumar, who is also the state Congress chief and his brother Suresh to strengthen their position in their home district of Ramanagara, a Vokkaliga heartland.

In Shiggaon, BJP's Bharath Bommai, son of Basavaraj Bommai lost against Congress' Yasir Ahmed Khan Pathan, who had faced defeat against the former Chief Minister in the 2023 Assembly polls.

Initially, former MLA Syed Azeempeer Khadri, a Congress' ticket aspirant, had raised a banner of revolt in Shiggaon, by filing his nomination as an independent, but later withdrew after intervention by party leadership.

In Sandur, Bellary MP Tukaram's wife E Annapurna of Congress won from the seat vacated by her husband, against BJP ST Morcha president Bangaru Hanumanthu, who is considered close to party leader and former mining barron G Janardhan Reddy.

Sandur is a Congress' bastion, and Tukaram had represented it four times.

Congress winning the by-polls is seen as "crucial" for Chief Minister Siddaramaiah to assert himself , amid demands for his resignation following charges against him in the MUDA site allotment case.

There were also behind-the-scenes political activities within the ruling Congress earlier this year, with a few ministers in his Cabinet holding closed door meetings, fueling speculation about leadership change. But such activities came to a halt following instructions from the party high command.

It is equally important for Shivakumar, who has not shied away from openly expressing his Chief Ministerial ambitions, amid speculations over "rotational Chief Minister formula," according to which he will become CM after two-and-half years (in this govt's five years tenure), but they have not been officially confirmed by the party.

The defeat in this by-poll is seen as a setback for state BJP President Vijayendra, who has been facing intense criticism and opposition from a section within the party, who have raised a banner of revolt against his leadership accusing him and his father, veteran leader B S Yediyurappa of "adjustment politics".

The Palestinian Hamas resistance movement says its fighters have killed at least 20 Israeli soldiers in northern parts of the besieged Gaza Strip in just two days, in retaliation for the occupying regime’s genocidal war on the Palestinian territory.

In a statement on Monday evening, Hamas said that fighters of its military wing, al-Qassam Brigades, “killed at least five occupation soldiers” in northern parts of the coastal territory earlier in the day.

It added that Hamas fighters also killed 15 Israeli soldiers in the war-ravaged region on Sunday.

The resistance movement’s “qualitative operation … confirms once again the failure of the criminal Zionist entity to suppress and eradicate the Palestinian resistance, which continues to direct qualitative strikes against its terrorist soldiers,” Hamas further said on its Telegram channel.

Palestinians have increased their resistance operations in the face of intensified Israeli aggression in northern Gaza that has claimed the lives of more than 1,000 over the past weeks.

“Our valiant resistance is waging a war of attrition with the criminal enemy, inflicting daily losses on its soldiers and vehicles, and all of [Israeli prime minister Benjamin] Netanyahu’s bets and dreams of achieving any of his goals are failing,” the Gaza-based resistance movement added.

Hamas also vowed that Israel’s ongoing crimes and aggression against Gaza would be met with increased resistance and painful strikes, which will continue until the aggression against Palestinians ends and the regime fully withdraws from the blockaded territory.

As the war in Gaza enters its 14th month, the Health Ministry reports that Israeli attacks have killed at least 43,603 Palestinians and wounded 102,929 others.

The UN humanitarian coordinator for Lebanon has warned that the “picture of life in Lebanon remains grim,” highlighting an "alarming" level of human suffering and significant humanitarian consequences due to the ongoing Israeli carnage.

Imran Riza, the UN Deputy Special Coordinator and Resident and Humanitarian Coordinator for Lebanon (UNSCOL), provided a stark overview of the Arab country's dire circumstances in a statement released on Monday.

“The current picture of life in Lebanon remains grim. Yesterday, airstrikes reportedly killed 23 people, including seven children, in the village of Aalmat in Mount Lebanon,” Riza said on X.

An airstrike in the city of Tyre on the same day resulted in the tragic deaths of five siblings from a single family, all of whom had special needs, according to his statement.

He added that in the last week, Israeli airstrikes have killed at least 241 individuals and left 642 others injured in Lebanon, as reported by the Ministry of Health.

“In the past month, more than 185,000 people have fled their homes in their search for safety within the country, bringing the total to over 870,000 people internally displaced,” Riza said

The UN official highlighted that numerous individuals, including the elderly and those with health issues, are staying behind while witnessing the ruins of their ancestral homes.

He urged for the swift safeguarding of civilian people and infrastructure, emphasizing the necessity to uphold international humanitarian law and end the ongoing violence.

Lebanon’s National News Agency reported that Israeli forces bombed a house in the town of Maydoun in Bekaa on Monday night, killing three people and destroying the house.

Earlier, Israel bombed the northern town of Ain Yaaqoub, killing at least 14 people.

The killings came as Israeli military continued to pound Lebanon, bombing shops selling electrical appliances in the southern city of Tyre and carrying out air raids on the towns of Shamshtar in eastern Baalbek and Roumine in southern Nabatieh.

Lebanon’s Ministry of Health said Israeli attacks killed at least 54 people across the country on Monday.

Israel’s merciless attacks continue despite calls from the UN Security Council for an immediate ceasefire and directives from the International Court of Justice urging measures to prevent genocide and alleviate the dire humanitarian situation in Gaza and Lebanon.

In Lebanon, at least 3,243 people have been killed and 14,134 others wounded in Israeli attacks since the war on Gaza began on October 7, 2023.

The Lebanese resistance movement Hezbollah opened a support front for Palestinians in Gaza only a day after the Israeli regime unleashed its genocidal war on the besieged territory.
