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.

US President Donald Trump-backed decision by the Centers for Disease Control and Prevention (CDC) to stop recommending giving infants a dose of the hepatitis B vaccine within 24 hours after birth is likely to lead to hundreds more infections, deaths, and millions of dollars in higher costs, according to new research.

The research, published in JAMA Pediatrics, comes as federal vaccine advisers to Health Secretary Robert F. Kennedy Jr. voted in December 2025 to reverse the long-standing recommendation to delay the first shot until at least two months of age for infants born to mothers who test negative for the virus.

While pediatricians, public health experts, and dozens of medical groups warned that it could harm children and their families, the new JAMA studies modelled the potential impact of the policy.

What Did The Studies Predict?

The first study estimated that delaying the first hepatitis B vaccine dose by two months for babies born in a single year to mothers who tested negative — about 80 percent of the 3.6 million US births annually — would increase lifetime health-care costs by at least $16 million, The Washington Post reported.

If vaccination were delayed by seven months, it would cost an additional $19.8 million.

The second study modeled what would happen if only 10 per cent of babies born to unscreened mothers received a birth dose; an additional 628 babies would get infected.

“One of the most concerning implications is how many more infected Hep B babies will we see,” said co-author Rachel Epstein, a pediatric and adult infectious diseases clinician at Boston Medical Center.

“A universal birth dose helps prevent a substantial number of infections in babies of a lifelong condition that we do not have a cure for,” she added.

CDC Had No evidence To Overturn Hepatitis B Vaccine Policy

Since 1991, all infants born in the US have received the first dose of hepatitis B vaccine within 24 hours of birth, a strategy that led to close to a 99 percent decline in infections among children.

Calling the universal birth-dose policy "a safety net", public health and medical experts noted that nearly 15 percent of pregnant women miss recommended hepatitis B screening. More than half of those who test positive do not receive appropriate follow-up care.

Delaying the initial dose also decreases the likelihood that a child will complete the three-shot series needed for full protection, hepatitis experts have said.

The authors argued that the CDC advisory panel departed from standards established for over three decades and failed to weigh key evidence.

“We noticed that the committee did not have the evidence they needed to inform their decision,” co-author Eric Hall, an assistant professor of epidemiology at Oregon Health and Science University, was quoted as saying to The Post.

“But this group kind of blew past all that and didn’t make any effort to fill the evidence gaps that they might have had. They just went ahead anyway.”

What is Hepatitis B?

Hepatitis B is a viral infection that affects the liver. It is highly contagious and spreads when blood, semen, or other bodily fluids from a person who carries the virus enter the body of someone who is not infected.

Hepatitis B can also pass from an infected mother to her baby during childbirth, whether through a vaginal delivery or a C-section. It is the most common route of transmission.

Vaccination is the most reliable way to prevent hepatitis B. The shots offer strong protection in infancy and continue to shield individuals well into adulthood.

Babies usually receive a three-dose series. A scientific review by the Vaccine Integrity Project found that 95 percent of healthy infants develop enough immunity after the third dose. The vaccine also lowers the risk of infection by nearly 70 percent in babies born to mothers who have hepatitis B.

A biryani feast followed by a serving of watermelon proved deadly for a family of four in Mumbai on Sunday. The incident was reported from the Pydhonie area, where an entire family passed away after eating biryani for dinner and some watermelon before calling it a night. They had watermelon around 1.00 am or 1.30 am, and their condition started to deteriorate around 5.00 am. They all experienced diarrhoea and nausea and eventually passed away. The mystery now remains: was it a case of accidental watermelon poisoning or something else? Abdullah Dokadia (40), his wife Nasreen Dokadia (35), and their two daughters, Ayesha (16) and Zainab (13), lost their lives, and the police are currently suspecting it to be a case of food poisoning. But can eating watermelon really kill you? Let us find out.

What are the signs of watermelon poisoning?

Watermelon is a popular summer fruit that people enjoy eating during the hotter months. It is 70 per cent water, highly hydrating, and also beneficial for weight loss. However, going overboard is discouraged by doctors, as overeating or consuming adulterated watermelon can lead to abdominal discomfort and digestive distress. Watermelon-related food poisoning can occur because of E. coli or salmonella infections. It can cause rapid dehydration, diarrhoea, cramps, fever, weakness, and, in extreme cases, even death.

What happens when you eat too much watermelon?

Dr Aarti Ullal, Physician and Diabetologist at Gleneagles Hospital, Parel, in an interaction with Health and Me, said, “Eating too much watermelon may lead to bloating, stomach discomfort, or loose motions, mainly because of its high water and natural sugar content. In some individuals, especially those with sensitive digestion, it can also cause acidity or mild cramps and disturb their peace of mind.”

Dr Ullal also stated that watermelon poisoning can occur when the fruit is contaminated with pesticides, chemicals, or bacteria due to poor handling or improper storage. The symptoms may include nausea, vomiting, abdominal pain, diarrhoea, and weakness. These are typically short-term digestive issues but may require medical attention if severe or if they interfere with daily routine. However, questions also arise regarding watermelon allergies. Watermelon allergy is rare and may cause itching in the mouth, swelling, rashes, or stomach upset soon after consumption.

How to check if your watermelon is adulterated?

To check if a watermelon is adulterated, look for an unnaturally bright red colour, cracks, a chemical smell, or an overly soft texture. Always wash the outer surface, as it may contain pesticides or chemicals, before cutting. Make sure to buy from trusted sources to avoid any health issues. Watermelon is safe and healthy to consume, but moderation and proper hygiene are key.

Can eating a watermelon kill you?

Conclusively, it can be said that eating a watermelon specifically should not cause deaths. However, if you bring the fruit home, it is advised to check it for signs of adulteration before consuming. It helps eliminate the possibility of side effects, just in case. However, if you experience food poisoning-like symptoms, consult a doctor immediately.

Viral hepatitis B and C – responsible for 95 per cent of hepatitis-related deaths worldwide – caused 1.3 million deaths worldwide, according to the Global Hepatitis Report 2026, released today by the World Health Organization.

Of these, 1.1 million people died from hepatitis B and 240,000 from hepatitis C. Liver cirrhosis and hepatocellular carcinoma were the main causes of hepatitis related deaths, stated the report released at the World Hepatitis Summit.

Further, India emerged among the 10 countries that account for 69 per cent of global hepatitis B-related deaths. The country is also among the 10 countries contributing to 58 per cent of hepatitis C-related deaths worldwide.

The Global Hepatitis Burden And Treatment Gap

Despite being preventable and treatable, transmission of hepatitis continues, with more than 4,900 new infections every day, or 1.8 million each year.

As per the WHO report, a whopping 287 million people were living with chronic hepatitis B or C infection in 2024.

The same year, 0.9 million people were newly infected with hepatitis B.

The WHO African Region accounted for 68 per cent of new hepatitis B infections, yet only 17 per cent of newborns in the region received the hepatitis B birth-dose vaccination.

Another 0.9 million hepatitis C infections were recorded in 2024. People who inject drugs accounted for 44 per cent of new infections, highlighting the urgent need for stronger harm reduction services and safe injection practices.

Of the 240 million people with chronic hepatitis B in 2024, fewer than 5 per cent were receiving treatment. Similarly, only 20 per cent of people with hepatitis C have been treated since 2015.

Hepatitis: Measurable Gains

Notably, global efforts to combat viral hepatitis have also delivered measurable progress in reducing infections and deaths since 2015.

The annual number of new hepatitis B infections has dropped by 32 per cent, and hepatitis C-related deaths have fallen by 12 per cent globally.

Hepatitis B prevalence among children under five has also decreased to 0.6 per cent, with 85 countries achieving or surpassing the 2030 target of 0.1 per cent.

“Around the world, countries are showing that eliminating hepatitis is not a pipedream, it's possible with sustained political commitment, backed by reliable domestic financing,” said Dr Tedros Adhanom Ghebreyesus, WHO Director-General.

“At the same time, this report shows that progress is too slow and uneven. Many people remain undiagnosed and untreated due to stigma, weak health systems, and inequitable access to care. While we have the tools to eliminate hepatitis as a public health threat, urgent scale-up of prevention, diagnosis, and treatment is needed if the world is to meet the 2030 targets,” he added.

Hepatitis: How To Prevent

The report noted that highly effective tools to combat hepatitis infections are already available. These include the hepatitis B vaccine, which protects more than 95 per cent of vaccinated people against both acute and chronic infections.

Further, the long-term antiviral treatment for hepatitis B can also help effectively manage chronic infection and prevent severe liver disease. Another is the Hepatitis C short-course curative therapy which lasts 8-12 weeks and can cure more than 95 per cent of infections.

The report identifies priority actions to accelerate hepatitis elimination as a public health threat. These include:

• Scaling up treatment for chronic hepatitis B infection,
• Stronger political commitment and financing,
• Improved coverage of hepatitis B birth-dose vaccination
• Expanded antiviral prophylaxis to prevent mother-to-child transmission of HBV infection
• Improve injection safety in both health-care settings and community practices.
