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.

After a long day at work, the occasional glass of wine helps many people unwind. However, some struggle to strike a balance and get involved in binge drinking habits. If you are someone who is unable to give up that frequent dose of cocktails, then a study claims that weight loss drugs can come to your rescue. Experts have found that alcoholics who are obese, when given Wegovy, could curb their drinking habits by as much as 70 per cent. A study in Denmark was led by experts from the Mental Health Centre Copenhagen and Frederiksberg Hospital, and experts used semaglutide on 108 obese patients seeking treatment for alcohol use disorder.

Can weight loss drugs help curb drinking habits?

Half the participants in the study were given 2.4 mg of the drug for six months. The other half were also given a dummy drug. Researchers found that people who were on weight loss drugs had fewer days of binge drinking. Furthermore, their alcohol cravings also dipped compared to people on placebo. Before the trial began, participants engaged in binge drinking on an average of 17 days per month.

Researchers also noted that people who were given semaglutide for six months saw their binge drinking days reduce to five in a 30-day period. This correlated to a 40 per cent dip in drinking days in a month, compared to a 26 per cent dip in the placebo group. These dummy drugs helped reduce drinking days to nine. In terms of alcohol quantity, trial participants drank roughly 2,200 g in the 30 days before the trial started. This meant about 154 drinks in a month, or five per day. Over a period of six months after the trial, there was an impressive 70 per cent dip — from an average of 154 drinks a month to 46 drinks a month in people who were taking semaglutide.

What are the benefits of semaglutide?

Alcohol consumption dipped by an impressive 47 per cent in the dummy drug group as well. The study found that overall alcohol consumption can be reduced among semaglutide users compared to people who were taking the placebo. Researchers found that semaglutide not only affects appetite but also influences biological mechanisms associated with addiction.

Independent researchers found that the results were encouraging and strong enough to be used in helping people struggling with alcohol use problems. However, more research is required in this area. Researchers also noted that there were no follow-ups with the participants after the semaglutide treatment ended. This means that experts could not be fully certain whether people reverted to their old drinking habits once they stopped using the medicine.

What are the health benefits of weight loss drugs?

Apart from inducing weight loss, weight loss drugs have the following health benefits:

1. Quitting smoking
2. Can help kick drug habits such as cocaine use
3. Lower risk of heart attack or stroke
4. May help reduce blood pressure and cholesterol to improve heart health
5. Lower risk of dementia

A whopping $600 million global vaccine aid meant for poorer nations has been put on hold by US Health Secretary Robert F. Kennedy Jr., according to a media report.

The delay in vaccines is putting pressure on the international humanitarian group Gavi, the Vaccine Alliance that distributes them, Politico reported.

Gavi noted that it has not received the funds due for the current and previous fiscal years, which account for about 15 percent of its budget.

The funds are set to expire on September 30 if the Trump administration does not release them.

The organization provides vaccines for 20 diseases, including measles, malaria and polio, to more than 50 low-income countries worldwide.

Sania Nishtar, Gavi CEO, told the newswire AFP, the funding gap, combined with reductions from other donors, has particularly impacted malaria vaccination efforts.

Gavi has delivered 39 million doses of a malaria vaccine to 25 African countries, where the disease predominantly affects children under five. Nishtar warned that tens of thousands of children could die as a result of the funding cuts.

Why Is Kennedy Holding Up Vaccines

Kennedy argues that the shots are obsolete with dangerous ingredients that the US has long since phased out.

“Gavi has refused to provide the United States with the specific data, studies, or detailed accounting of how US funds are used,” Emily Hilliard, senior press secretary at the Health and Human Services Department, said in a statement.

Advocates for Gavi, the Vaccine Alliance warn that withholding funds could cost children’s lives. They argue that the vaccines used are safe and better suited for developing regions, where refrigeration is limited and administering booster doses is more difficult.

Hilliard said Gavi has declined to create a plan to phase out thimerosal, a mercury-based vaccine preservative that Kennedy believes may be linked to autism. The administration has asked Gavi to stop using vaccines containing this preservative.

Thimerosal is used in several vaccines distributed by Gavi, including combination shots protecting against multiple diseases, according to former chief executive Seth Berkley. He explained that many developing countries rely on multi-dose vials, which require less refrigeration but may contain thimerosal to prevent contamination.

Without such vaccines, “kids would go without vaccines… and that would lead directly to deaths,” Berkley said.

During testimony before the Senate Appropriations Committee, Kennedy also raised concerns about a vaccine used to protect against diphtheria, tetanus and pertussis, claiming it had been discontinued in the US due to safety issues.

Gavi responded that the vaccine remains in use because it offers longer-lasting protection and requires fewer doses. The organization said the vaccine “is safe and effective and estimated to have saved 40 million lives in the past 50 years,” the report said.

A plant-based diet is highly recommended for a healthy heart — weight watchers can also benefit from it, as can diabetics. When one goes vegan, the biggest change comes when one moves from dairy milk to oat, almond, or soy milk. Parents, too, are now shifting their children to trendy vegan milk options — little do they realise that this could bring their worst fears to life. According to the British Society for Allergy & Clinical Immunology, drinks that are aimed at children and often marketed as healthy are usually loaded with sugar and offer little or no nutrition.

Why has plant milk become a preferred choice?

Experts found that children under five years of age are more prone to malnutrition, tooth decay, or even obesity. The study is the first of its kind, and its warning will be published in the coming week. It is backed by the British Dental Association and the British Dietetic Association. Doctors say that plant-based drinks are often compared to cow’s milk in terms of nutrition. However, these claims are not supported by current evidence.

Why is plant milk discouraged for children?

Plant milk has gained popularity in recent years because of the health benefits that many believe it offers. While adults may benefit from it in several ways, toddlers must not be given these packaged, sugary drinks. The added sugars can become nothing more than a frequent treat for children, who may lose their milk teeth sooner and suffer from decay. Researchers found that families are often convinced that plant milk is good for children, but these oat, almond, and soy versions of milk are processed and full of sucrose and fructose syrups.

According to a report, most of these drinks contain large amounts of sugar in the form of maltodextrin, glucose syrup, sucrose, and fructose. A 350 ml glass of such milk contains more than double a toddler’s daily sugar allowance. Ideally, toddlers should not be given more than 14 grams of sugar every day. Their young bodies can struggle to absorb vitamin B12 and calcium from plant drinks. The BSACI recommends that parents opt for unsweetened, fortified plant milk instead, as these can play a crucial role in supporting children’s health.

How do ultra-processed foods affect children’s health?

Ultra-processed foods (UPFs) are defined as food groups that undergo a great deal of processing — the most natural foods fall under Group 1, while heavily processed foods are placed under Group 4. While these do not definitively determine how healthy a food option is, they indicate the level of processing involved. Highly processed foods are associated with a range of health problems, which is why it is important to make informed dietary choices.
