Heart disease is often linked to high cholesterol, obesity, or lack of exercise. However, there is mounting evidence that suggests that mental health plays a crucial role in cardiovascular well-being. Stress, anxiety, and depression can silently strain the heart, increasing the risk of serious complications.

A recent study, published in Nature Human Behaviour, showed that loneliness has a significant impact on proteins present in a person's blood. For the study, researchers used data from more than 42,000 participants to explore whether the 9.3% who reported social isolation and 6.4% who reported loneliness had different levels of proteins in their blood compared with those who did not. The researchers then studied data that tracked the health of participants over an average 14-year period.

"We found around 90% of these proteins are linked to the risk of mortality," Dr Chun Shen, Fudan University in China, who is also the lead researcher said. "In addition, about 50% of the proteins were linked to cardiovascular disease, type 2 diabetes and stroke," he added.

Dr Shrey Kumar Srivastav, senior consultant at Sharda Hospital, said that subtle symptoms of heart disease, such as fatigue, shortness of breath, swelling in the lower legs, dizziness, and jaw pain, are often overlooked or attributed to stress and ageing. "Women, in particular, may experience atypical signs like extreme fatigue, indigestion, or upper abdominal pain instead of classic chest pain, leading to delayed diagnosis," he added.

Can Mental Health Issues Trigger Heart Diseases?

Chronic stress can trigger harmful cardiovascular effects, including elevated blood pressure, increased heart rate, and inflammation—key contributors to heart disease. Anxiety and depression further impact heart health by disrupting sleep patterns, raising stress hormone levels, and encouraging unhealthy habits like poor diet and inactivity.

Mental health issues like depression and anxiety have a profound impact on the heart. They don’t just affect emotions but can increase inflammation and put extra strain on the cardiovascular system, warns Dr Srivastav.

Certain risk factors, such as obesity and diabetes, disproportionately affect women, making them more vulnerable to heart failure with preserved ejection fraction (HFpEF). However, due to gender-specific symptom variations, heart disease in women often goes undiagnosed for longer.

Obesity is more prevalent in women than men and is a major risk factor for heart failure. Diabetes, too, has a greater impact on women’s heart health, yet diagnosis and treatment delays are common. Addressing this gap requires increasing awareness, training healthcare providers, and promoting early diagnostic tools,” explains Dr Srivastav.

How Can You Protect Your Heart?

A simple yet effective way to support heart health is by committing to a brisk 30-minute walk daily. Walking not only helps regulate blood pressure and manage weight but also improves circulation and reduces stress.

"Regular physical activity, paired with a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins, significantly lowers cardiovascular risks," advises Dr Srivastav.

Heart disease can often go undetected until a major event occurs, making routine screenings essential.

- For women: Begin screenings around age 30 and continue with regular checkups.

- For men: Start screenings at age 35.

Health screenings, including blood pressure checks, cholesterol tests, and electrocardiograms (ECGs), are critical for early detection of silent heart conditions.

As of 8am, in Delhi, the city's average AQI stands at 513 according to aqi.in. Major pollutant in the Delhi's air include PM2.5, PM10, Carbon Monoxide, Sulfur Dioxide, Nitrogen Dioxide, and Ozone. The AQI is equivalent to smoking 11.8 cigarettes per day, 82.6 cigarettes per week, and 354 cigarettes in a month. Amid this, doctors have called this major public health hazard, and warned people about the damage it can cause to our organs.

"The smaller the particle the more dangerous it is because it really goes into the depth of our lungs and causes damage there," says Dr. Vivek Nangia, Vice Chairman and Head of Pulmonology at Max Healthcare Saket, as told to news agency PTI.

Speaking to news agency ANI, Dr. Naresh Trehan, MD, Medanta, called the current situation “a major, major health-wise hazard,” stressing that the impact is unfolding across all age groups.

“A disaster for humanity,” says Dr Trehan

According to Dr. Trehan, pollution is now causing illness “many fold,” with outpatient departments packed with people suffering from cough, cold, chest congestion, asthma attacks, and severe breathing difficulties. But his biggest concern goes beyond the lungs.

He explained that the particulate matter present in polluted air moves far deeper into the body than most people realise. “These particulates go everywhere,” he told ANI. “They get absorbed into the blood, they go to your brain, they go to your kidneys, they go to your liver.”

Dr. Trehan added that the chronic effects of such constant exposure are making the public “sicker than they would be if they were living in a cleaner area.” Children, he warned, face an even greater threat as trapped toxic gases and particulate matter during winter behave “like a gas chamber,” potentially harming neurological development.

Dr Nangia breaks down the danger of PM2.5

Giving the scientific context behind this damage, Dr Nangia told PTI that the toxicity varies by particle size.

Particles larger than 5–10 microns usually stay in the upper respiratory tract, causing symptoms like throat irritation, watery eyes, and a runny nose. However, “a particle size less than 2.5 microns goes into the lungs,” he explained. Even more dangerous are particles smaller than 0.5 microns, which “go directly into the bloodstream from the lungs and trigger an inflammatory cascade.”

This cascade, Dr. Nangia said, spreads through the body and can inflame various organs—contributing to asthma, heart disease, high blood pressure, and even conditions like rheumatoid arthritis.

Reading Delhi's AQI

As per the aqi.in there are six categories under which air pollution levels are measured, which are as followed:

• Good 0 to 50
• Moderate 50 to 100
• Poor 100 to 150
• Unhealthy 150 to 200
• Severe 200 to 300
• Hazardous 301+

Fact: AQI in Delhi is 1.9 times above than in India

Public Health Emergency

There are many short-term and long-term impact on public health from the constant exposure of air pollution. As per IQAir, in the short-term, people experience irritation in eyes, throat, and nose, along with irregular heartbeats, asthma attacks, coughing, chest tightness, and difficulty breathing.

Prolonged exposure also intensifies these risks and leads to long-term effects such as chronic respiratory illnesses like bronchitis, asthma, and emphysema. Pollutants can also damage lung tissue, increasing the likelihood of lung cancer. Air pollution also leads to an increased risk of heart attacks and strokes and could also be linked to premature death.

Former UK Prime Minister David Cameron revealed his prostate cancer diagnosis and has called for a targeted screening. In an interview with Times, he said, "You always hope for the best. You have a high PSA score - that is probably nothing. You have an MRI scan with a few black marks on it. You think, ‘Ah, that’s probably OK.’ But when the biopsy comes back, and it says you have got prostate cancer. You always dread hearing those words. And then literally as they’re coming out of the doctor’s mouth you’re thinking, ‘Oh, no, he’s going to say it. He’s going to say it. Oh God, he said it.’"

The former PM, 59, said that he had a prostate-specific antigen (PSA) test for the screening that looks for proteins associated with the form of the disease. His result was high, and a biopsy after that revealed his cancer.

It was his wife, Samantha, who urged him to get tested, after the couple heard the founder of Soho House, Nick Jones, talking about his diagnosis on radio. Cameron had received focal therapy for treatment, where electrical pulses target and destroy the cancer cells.

Cameron Calls for National Prostate Cancer Screening

He has urged the government to introduce a national screening programme to detect prostate cancer earlier, when treatment is far more effective.

Cameron said, “I want to, as it were, come out. I want to add my name to the long list of people calling for a targeted screening programme.

“I don’t particularly like discussing my personal intimate health issues, but I feel I ought to. Let’s be honest. Men are not very good at talking about their health. We tend to put things off.”

Prostate Cancer: The UK’s Most Common Male Cancer

Prostate cancer remains the most common cancer among men in the UK, with around 55,000 cases diagnosed every year. Despite this, there is currently no national screening programme because of concerns over the accuracy of PSA tests.

In October 2024, six-time Olympic gold medallist Chris Hoy revealed he had been diagnosed with terminal stage 4 cancer. His prostate cancer had spread to his shoulder, pelvis, hips, ribs and spine.

Cameron, who stepped down as prime minister and MP in 2016, returned to government as foreign secretary under Rishi Sunak in 2023 and was appointed a life peer in the House of Lords.

New Screening Trial Begins Across the UK

Cameron’s announcement comes just days after eligible men began receiving invitations to join a major trial testing the most promising prostate cancer screening technologies.

The Transform project will evaluate new screening methods against current NHS diagnostic pathways, which typically include blood tests and biopsies. The trial is being run in partnership with the NHS through the National Institute for Health and Care Research, which has committed £16 million, with additional funding from Prostate Cancer UK.

Its launch coincides with the UK National Screening Committee’s upcoming decision on whether current evidence supports introducing national screening.

‘Men’s Lives Should Not Be Left to Chance’

Chiara De Biase, director of health services, equity and improvement at Prostate Cancer UK, welcomed Cameron’s openness about his diagnosis.

“We’re glad to hear that David Cameron found his prostate cancer at an early stage and had successful treatment,” she said. “We thank him for sharing his story and raising vital awareness of this disease, which is completely curable if found early. But men’s lives should not be left to chance.

“We lose 12,000 dads, brothers, sons and friends every year. We’ve reached a tipping point in the UK, with too many men dying from a curable disease and worse outcomes for higher-risk groups like black men and men from working-class communities.

“Prostate cancer is the last major cancer without a screening programme, and we need change now.”

What Happens In Prostate Cancer?

As per Urology Care Foundation, prostate cancer develops when abnormal cells form and grow in the prostate gland. Not all abnormal growths, also called tumors, are cancerous. Some are benign growth and are not life threatening. They also do not spread to nearby tissue or other parts of the body.

Whereas cancerous growths can spread to nearby organs and tissues, as in the case of Biden.

Donald Glover, who formerly performed under the stage name of Childish Gambino revealed that he had a stroke last year due to which he had to cancel his world tour date. Now, 42, he said he is dealing with an "ailment", after the New Orleans performance. He revealed that after that performance, he had gone to hospital in Houston, where he discovered that his condition required surgery.

As a result, he postponed his tour, which eventually was cancelled. This tour was remainder of his US tour and his UK, European, and Australian tour dates. He wrote: "Unfortunately, my path to recovery is taking longer than expected."

While performing at Tyler, the Creator’s Camp Flog Gnaw festival in Los Angeles on Saturday, Glover shared the real reason behind his sudden tour halt.

“I was doing this world tour … really loving seeing you guys,” he said, as reported in Guardian. “I had a really bad pain in my head in Louisiana and did the show anyway. I couldn’t really see well, so when we went to Houston, I went to the hospital and the doctor was like, ‘You had a stroke.’”

He joked that his first thought was, “Here I am still copying Jamie Foxx,” referencing Foxx’s 2023 stroke, before admitting his immediate fear was that he was letting fans down—though he knows that isn’t true.

Glover added that doctors also found he had a broken foot and a hole in his heart, which required two surgeries.

“They say everybody has two lives, and the second starts when you realize you only have one,” he told the crowd. “You’ve got one life, guys, and the life I’ve lived with you has been such a blessing.”

Glover, a five-time Grammy winner, has since retired the Childish Gambino moniker after releasing his final album, Bando Stone & the New World. The cancelled tour had been planned as his farewell to the stage name.

What Happens In A Stroke?

When you have a stroke, the blood supply to part of your brain is interrupted. This cause brain cells to die from a lack of oxygen and nutrients. This could also lead to lasting brain damage, long-term disability, or even death.

What Does It Mean To Have A Hole In Heart?

As per Cleveland Clinic, hole in heart means to have an atrial septal defect or ASD, which is an opening in the wall that separates the heart's chambers. While some small holes may close on their own and have no symptoms, larger holes can cause blood to mix between oxygenated and deoxygenated sides, forcing the heart to work harder and potentially leading to health issues like shortness of breath. Treatment options range from monitoring to surgery or minimally invasive procedures, depending on the size and severity of the defect.

Types of holes in the heart

• Atrial Septal Defect (ASD): A hole in the wall (septum) between the two upper chambers (atria) of the heart.
• Ventricular Septal Defect (VSD): A hole in the wall between the two lower chambers (ventricles).
• Patent Foramen Ovale (PFO): A common type of ASD, where the opening between the atria doesn't close after birth.

What Happens When Someone Has A Hole In Their Heart?

• Normally, the left side of the heart pumps oxygen-rich blood to the body, and the right side pumps oxygen-poor blood to the lungs.
• A hole in the heart allows oxygen-rich and oxygen-poor blood to mix.
• This can cause oxygen-rich blood to recirculate to the lungs instead of the body, or cause the heart to pump extra blood to the lungs.
