Mosquitoes are a big part of the ecosystem, but often are a nuisance as they bite and feed off of us. Their bites cause itchy red bumps and spread infections and allergies in our bodies. But have you ever wondered why they bite certain people more than others? While some people are plagued by mosquito bites, others barely notice them. Here are some interesting facts about mosquitoes that you must know about!

1. Carbon Dioxide:

Mosquitoes are attracted to a certain smell that emits from the human body that is present in the human skin and sweat, mosquitoes can sense the carbon dioxide or CO2 we breathe out. The more active you are, the more CO2 you emit and the more mosquitoes will be attracted to you. Researchers are still investigating the cause of the variation of body odour that brings them to you, possibly genetics or certain bacteria. The unique combination of sweat and skin bacteria creates a scent that mosquitoes find irresistible. Some chemicals in sweat, like lactic acid and ammonia, are especially attractive to them.

2. Colours

While the reason isn't fully understood, mosquitoes seem to be drawn to dark colours like black more than lighter ones. So, ditch the dark outfit next time you're in mosquito territory. It has been noted that mosquitoes are more likely to leave lighter colours alone.

3. Heat and Vapour

Mosquitoes can detect your body's heat and water vapour, acting like a beacon guiding them right to you. So next time you're feeling sweaty, be aware you might be attracting a lot of mosquitoes. If you are working out or doing something that is making you sweat and your body heat rise, the mosquitoes nearby will be instantly attracted to you. Even mosquitoes are careful about who they pick as a host, some studies even suggest that they like a certain body temperature to feed off of.

An interesting fact about mosquitoes is that they can learn to like a host. They have their own preferences and if they meet a certain person who fits their criteria they might be the next host they move onto. In an older study, it showed that 20 per cent of people with mosquito-borne diseases accounted for 80 per cent of diseases transmitted in the population. They suggest that they only bite a certain set of people within the population.

4. Other factors:

Studies suggest mosquitoes might learn to prefer certain people based on things like what you've been drinking. In a 2002 study, there could be many reasons they like alcohol to making your body temperature high etc. Even pregnant women seem to be extra attractive to them due to higher body temperature and CO2 output.

The World Health Organization’s November 2024 report revealed that chronic obstructive pulmonary disease (COPD) remains the fourth leading cause of death worldwide. The condition was responsible for an estimated 3.5 million deaths in 2021 according to the latest available global data. COPD is a common and serious lung disease, and the WHO noted that smoking, indoor and outdoor pollution, and harmful inhalants are among its most significant triggers.

Children, too, are increasingly at risk due to high pollution levels, secondhand smoke and early-life respiratory infections. With winter pollution worsening across many Indian cities, especially Delhi NCR, experts say this is the right moment to revisit how COPD can be prevented through everyday habits and early interventions.

What COPD Really Is

COPD is identified as a chronic lung disorder that results in persistent breathlessness, chronic cough and long-term mucus production. According to the pulmonologist, the disease is a major global health burden linked to high levels of mortality and long-term disability across populations.

The condition develops slowly and often goes unnoticed in its early stages. Over time, narrowed airways and irreversible lung damage make breathing progressively more difficult. The pulmonologist explained that the air people breathe plays a crucial role in determining long-term lung health, especially for those living in severely polluted areas.

Why COPD Happens

COPD is primarily caused by the inhalation of harmful particles and gases. These include cigarette smoke, secondhand smoke, indoor pollution from biomass fuel, outdoor smog, chemicals, dust and repeated lung infections. The pulmonologist added that a small percentage of COPD cases are due to a rare genetic condition known as alpha-1 antitrypsin deficiency. In such cases, checking family history becomes important for early detection.

Preventing COPD: What Experts Recommend

Preventing COPD requires a comprehensive and consistent lifestyle strategy. While quitting smoking remains the single most effective step for protecting the lungs, the pulmonologist stressed that prevention goes far beyond just avoiding cigarettes. Clean air, healthy food, ideal body weight and regular vaccinations all play a key role.

The pulmonologist shared nine essential tips that can help significantly reduce the risk of COPD, particularly for people living in high-pollution regions such as Delhi NCR.

9 Essential Tips to Prevent COPD

• Avoid smoking completely and seek medical support to quit if necessary.
• Avoid secondhand smoke and maintain distance from people who smoke.
• Reduce indoor pollution by switching from biomass fuels to LPG, keeping windows open for ventilation and using air purifiers when required.
• Limit exposure to outdoor pollution. Wear a mask during high pollution days and stay indoors when air quality is poor. Consider shifting residence or workplace if the area remains persistently polluted.
• Use proper protective gear, including masks, if your profession involves dust, chemicals or industrial fumes.
• Avoid exposure to strong or irritating smells that can trigger respiratory issues.
• Maintain healthy lifestyle practices such as regular exercise and a balanced diet.
• Keep body weight within a healthy BMI range because excess weight worsens breathing and being underweight can increase vulnerability to more severe COPD.
• Ask a doctor about preventive vaccinations such as influenza and pneumococcal shots when appropriate.

A new meta-analysis published in the journal Stroke reports that GLP-1 receptor agonists such as semaglutide may help reduce the risk of ischemic stroke in patients who do not have diabetes. The findings come from a review of preclinical studies and highlight the growing interest in how these widely used drugs may offer benefits beyond blood sugar control.

What GLP-1 Drugs Are and How They Work

GLP-1 receptor agonists are a class of medications that mimic a natural hormone called glucagon-like peptide-1. This hormone helps regulate appetite, insulin release and blood sugar levels. Drugs in this category include semaglutide, liraglutide, exenatide, lixisenatide and dulaglutide. Semaglutide is sold under the brand names Wegovy and Ozempic.

These medicines were originally developed for people with type 2 diabetes. Over time, scientists observed additional effects such as reduced appetite, improved metabolic markers and modest cardiovascular protection. This led to their approval for weight management in people without diabetes. Today, GLP-1 drugs are among the most prescribed medications for obesity and are being studied for heart failure, kidney disease and other conditions. However, their potential benefits in non-diabetic patients at risk of stroke remain largely unexplored.

What the New Review Examined

Researchers from Aarhus University in Denmark conducted the meta-analysis to understand whether GLP-1 drugs could reduce the severity or likelihood of acute ischemic stroke in people who do not have diabetes. The team examined 31 preclinical trials conducted between 2011 and 2024. All studies were carried out in rodent models.

The included drugs were given either orally or through subcutaneous injections. The researchers compared animals receiving GLP-1 drugs with those given a placebo. They reviewed outcomes such as infarct volume, neurological recovery and markers of cell injury.

Findings Show Promising Neuroprotective Effects

Across the studies, animals treated with GLP-1 drugs showed significantly smaller infarct volumes than those given a placebo. They also demonstrated better neurological function after stroke.

Lead author Michael K. Michaelsen from the department of clinical medicine at Aarhus University wrote that the mechanisms behind these benefits are not yet clear. He noted that the effects appear to extend beyond blood sugar regulation. According to the paper, GLP-1 drugs may act on multiple pathways involved in stroke injury including inflammation, oxidative stress and cell death. The authors observed reductions in oxidative stress markers, inflammatory mediators and indicators of cell death in several trials. However, they cautioned that these findings do not prove causality.

Human Impact Still Unknown

Since all the analyzed studies were in animals, experts say it is too early to conclude whether GLP-1 receptor agonists could improve stroke outcomes in non-diabetic patients. Clinical trials will be needed to confirm whether the neuroprotective effects translate to humans.

The authors noted that if future research shows that these drugs do not affect platelet function or clotting during the acute phase of stroke, they could one day be used even before patients undergo neuroimaging. They wrote that early prehospital administration could potentially offer faster protection during the critical first moments of stroke.

For most people, grief arrives slowly. For survivors of suicide loss, it crashes in without warning and never quite leaves the room. Around the world, millions of people carry this quiet, complicated grief. This one is laced not only with heartbreak, but often with unanswered questions, guilt, shock, and the haunting feeling that maybe something, anything, could have been different.

International Survivors of Suicide Loss Day is more than a remembrance; it is a reminder that those left behind are still learning how to live with an absence that reshaped everything. For Harry Corin, *Amitava Kumar, writer Arianna Rebolini, and *Aastha Ganguli that reshaping began the moment they learned their loved one had chosen to leave the world.

Their stories are different, their cultures and circumstances varied, but their grief echoes the same truth: suicide does not end a life alone. It alters the lives of everyone who loved them.

“I spent a decade hiding the truth”

Harry Corin, who was raised in St Ives, a small town in England was only 12 when his father died by suicide. At an age when children are learning how the world works, Harry was suddenly thrown into a reality too heavy for words.

For more than a decade, through school, university, and his first jobs—he kept the truth locked inside.

It was fear that speaking about suicide would make people uncomfortable, fear that it would expose the overwhelming pain he had never processed. But the first time he spoke about it openly, something shifted.

He realized how powerful honest conversation could be, and how desperately men needed safer spaces to have them.

Now a mental health speaker and founder of a global workplace wellbeing company, Harry’s life mission is rooted in preventing others from reaching the point his father did. He believes suicide prevention begins long before a crisis, through environments where vulnerability is accepted, emotions are not dismissed, and support is offered without hesitation.

But his journey has also been shaped by the way he experiences the world. Diagnosed with ADHD in his late 20s, he finally had a lens that explained years of inner restlessness. This understanding didn’t erase the pain—but it helped him reclaim a narrative he had once buried.

Losing the heart of his family

In Kolkata, many families live close, emotionally, financially, historically. This was true for *Amitava Kumar, whose beloved uncle, affectionately called 'Choto Kaka', was the youngest of seven brothers.

Amitava remembers him as charming, generous, and deeply loved by nieces and nephews. He had a thriving business and carried much of the joint family’s financial responsibilities after Amitava’s father moved to Delhi. He handled his grandparents’ medical expenses, supported siblings, and was the emotional anchor of the household.

But behind that warmth was a man whose emotional vulnerability was often exploited by friends. His generosity made him an easy target for those who took advantage of his kindness and financial success.

At home, tensions began to grow. Arguments escalated. Pressure mounted. He began drifting away from the family that adored him.

Then came the debts: quiet, creeping, and devastating.

“One day,” Amitava says, “we were dumbstruck to hear that our beloved Choto Kaka had taken his life.”

It was February 1995 when Amitava was 28, and it was the last he saw him—just a few months before his own wedding, which was to be held in May in the same year. His uncle had blessed the photo of his bride and promised to meet her soon.

The family marked his memory with a stone inscription at Brahma Mandir in Pushkar, a way of leaving his soul at the feet of the divine. Yet the void he left remains unfillable.

“Grief becomes complicated when distance exists”

For New York-based writer Arianna Rebolini, grief came from a different angle, not in the heart of a close-knit family, but through a friendship that had drifted apart.

At 28, she learned that her once-inseparable college friend, Alice, had died by suicide. It was a loss wrapped in guilt. They had bonded deeply in their youth, often over their shared struggles with mental health. But adulthood had separated them—new cities, new routines, and the quiet fading that happens between even the closest friends.

“There’s a shame in realizing you weren’t there,” she says. “I wasn’t in a position to know that she needed help.”

Arianna carried the dual weight of grief and self-blame. She dreamt about Alice for years. She combed through old messages. She found a Facebook text from Alice, sent two months before her death, that she had never responded to.

“It still hurts,” she admits.

To heal, Arianna confronted the details of Alice’s final months, refusing to shy away from them, a path many survivors fear but some desperately need. As she immersed herself in Alice’s poetry and art, she found connection, closure, and eventually clarity.

Through years of writing and research, her understanding of suicide transformed. She even wrote a gutsy, riveting memoir that explores suicides, named Better: A Memory About Wanting to Die.

“When Love Is Lost Too Soon”

One of Aastha’s fondest memories is how Gauri taught her to see the world differently. “She always had another perspective,” she recalls. “I was taught to look at things one way, but she showed me there were multiple ways to understand the same moment.” Gauri listened deeply, helped people find clarity, and reminded those around her that judgment should never be the first instinct, a lesson Aastha carries with her even now.

But healing, she says, has been “up and down, not linear at all.” Three years on, the grief still lives in her bones. Music helps. Talking about Gauri helps. Sharing her story keeps her close. What hurts most is when people assume there should be a deadline for mourning. “People told me, ‘It’s been two or three years, you should move on.’ But I never will. She’ll always be a part of me.”

Aastha has also seen how people oversimplify suicide. “They think there’s one reason someone does it. But it’s never one thing, it’s a culmination of small things.” What pains her deeply is when people say someone “wasn’t strong enough.” To her, it reduces a full, complex human being to their final moment. “She was so much more than what happened in the end. It’s not about strength or weakness.”

Like many survivors, she carried guilt, wondering whether she could have done more or helped in a different way. With time, she learned that loving someone doesn’t mean you can always save them. That understanding has shaped how she supports others now. She no longer pushes people to open up; she waits, gives space, and allows them to come to her. “Helping someone isn’t one-size-fits-all. Some people need words. Some need silence. Some just need presence.”

She hopes communities learn to stop minimizing struggles and stop forcing their own solutions onto someone else’s pain. “If a person says they’re struggling, don’t judge them through your lens. Find what they need, not what you needed.”

To anyone grieving a suicide loss, her message is gentle but firm: “Don’t be afraid to say how they died. When we hide it, we create shame, and that silence can hurt others who might be feeling the same way.” Above all, she urges kindness, especially toward those who might be reaching out in unclear or complicated ways. “Even if someone says it for attention, it’s better to talk to them than dismiss them.”

Gauri had always been an advocate for mental and emotional wellbeing, and she taught Aastha how to find peace within herself. Today, Aastha tries to carry that forward. “The only thing that has changed,” she says softly, “is that now I want to spread the same message she gave me, so others can find their safe space too.”

The Invisible Weight Survivors Carry

The stories of Harry, Amitava, Arianna, Aastha reveal what most people don’t see:

Survivors of suicide loss often live with:

• guilt, even when it’s undeserved
• unanswered questions that never resolve
• shame imposed by societal silence
• the ache of unfinished conversations
• anger, confusion, love, and longing, all at once

Their grief is not linear. It’s a spiral. Some days are survivable. Others reopen wounds that never fully healed.
