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.

The American Red Cross has declared a national blood supply crisis for only the second time in its history, warning that blood donations have dropped to a four-year summer low while demand from hospitals continues to rise.

The organization says the shortage has reached a point where patient care could be affected if donations do not increase immediately.

According to the Red Cross, the crisis is being driven by a combination of fewer blood donations during the summer months and higher demand for blood products, particularly during the peak trauma season.

Type O Blood Supply At Critical Levels

One of the biggest concerns is the shortage of type O positive blood, the most commonly transfused blood type in the United States.

The American Red Cross said it currently has less than a one-day national supply of O-positive blood. They have limited distributions to individual hospitals to ensure the blood type is available for the most life-threatening emergencies.

Supplies of O-negative blood, the universal blood type used in trauma situations when there is no time to determine a patient's blood group, are also not sufficient.

The Red Cross noted that many blood collection organizations across the country are reporting similar challenges this year.

Why Summer Is Especially Challenging

Summer has always been one of the most difficult seasons for maintaining a stable blood supply. Schools and colleges, which frequently host blood drives, are closed, while vacations and holiday travel often disrupt regular donation schedules.

At the same time, hospitals continue to require blood due to surgeries, cancer treatments, childbirth complications, chronic illnesses, and trauma patients.

The Red Cross said these seasonal challenges have intensified this year, resulting in the lowest level of summer donations seen in four years.

In its announcement, the American Red Cross said, "The American Red Cross has declared only the second national blood supply crisis in its history after blood donations fell to a four-year summer low, deepening an emergency shortage that threatens the availability of lifesaving blood for patients across the country."

The organization also emphasized the urgency of public participation, stating, "Just three more donors at each blood drive this summer can end this crisis and stabilize the blood supply."

Encouraging immediate action, the Red Cross added, "Don't wait. Those who may be eligible are urged to book an appointment now."

Impact Of Blood Supply Shortage

The Red Cross warned that some patients are already experiencing delays in receiving blood transfusions as supplies become increasingly strained.

By prioritizing blood distribution to the most urgent cases, hospitals may face difficult decisions about how limited supplies are allocated.

Healthcare providers rely on a steady stream of donations because blood has a limited shelf life. Red blood cells can generally be stored for about six weeks, while platelets last only a few days, making continuous donations essential for maintaining adequate supplies.

The American Red Cross has urged all eligible donors, regardless of blood type, to schedule a blood donation as soon as possible. Officials believe that even a slight increase in donations at blood drives across the country could quickly stabilize blood inventory.

Legendary singer-songwriter Carly Simon has shared that she has been diagnosed with Parkinson's disease and recently underwent treatment for skin cancer, offering fans a personal explanation for her years-long absence.

In a heartfelt statement released on July 27, the 83-year-old You're So Vain singer revealed that she has been privately navigating multiple health challenges while continuing to work on new music.

The announcement comes just weeks before the release of Comes in Waves, her first album of original material since 2008.

Carly Simon Opens Up About Parkinson's Disease

Addressing her prolonged absence from public life, Simon wrote, "So many people have written to me, kindly wondering about my relative silence, asking how I am and what I have been doing."

She then revealed the reason behind her disappearance. She said that she has been learning how to live with Parkinson's disease.

Simon explained that her health struggles initially began with severe arthritis in her hips and knees, leading to joint replacement surgeries. However, when her mobility continued to worsen after surgery, she sought further evaluation at the Mayo Clinic, where she was diagnosed with Parkinson's disease.

What Is Parkinson's Disease?

Parkinson's disease is a progressive neurological disorder that primarily affects movement. It develops when nerve cells in the brain that produce dopamine gradually deteriorate. Common symptoms include:

• Tremors
• Muscle stiffness
• Slowed movement
• Balance and coordination problems
• Fatigue
• Changes in speech and facial expressions

Although there is currently no cure, medications, physical therapy and lifestyle interventions can help manage symptoms and improve quality of life.

By sharing her diagnoses, Simon joins a growing number of public figures who have spoken openly about living with Parkinson's disease, helping raise awareness about the condition while reducing stigma.

India's National Viral Hepatitis Control Program (NVHCP) has screened more than 210.6 million people and treated over 612,000 patients as of March 2026, according to the Ministry of Health and Family Welfare ahead of World Hepatitis Day 2026.

Viral hepatitis remains a major public health challenge. The World Health Organization (WHO) estimates that hepatitis caused 1.34 million deaths globally in 2015, a toll comparable to tuberculosis. In India, an estimated 40 million people live with Hepatitis B, while 6-12 million have Hepatitis C.

According to the 2021 HIV Sentinel Surveillance:

• 0.85% tested positive for Hepatitis B
• 0.29% tested positive for Hepatitis C

This is roughly equivalent to 1 in 118 people testing positive for Hepatitis B and 1 in 345 for Hepatitis C among those surveyed.

India's Plan to Eliminate Hepatitis

Launched in 2018, the National Viral Hepatitis Control Program aims to:

• Eliminate Hepatitis C by 2030
• Reduce infections, illness and deaths caused by Hepatitis B and C
• Prevent complications such as cirrhosis and liver cancer
• Reduce the burden of Hepatitis A and E

"Since 2018, India's National Viral Hepatitis Control Program has offered free screening and treatment for Hepatitis B and C nationwide. Smart use of local funding, cheaper generic drugs, and existing health programs has helped expand this care further," the government said in an official statement.

"Services are now moving from district hospitals down to local health centers, bringing testing and treatment closer to everyone," it added.

How Does It Work?

• Covers Hepatitis A, B, C, D and E
• Free testing and medicines for Hepatitis B and C
• Digital patient monitoring through the NVHCP-MIS portal
• Focus on prevention, awareness, screening and treatment
• The NVHCP is integrated with several health programs to expand access to prevention and care.
• Universal screening of pregnant women for Hepatitis B
• Hepatitis B birth dose for every newborn
• HBIG for infants born to Hepatitis B-positive mothers within 24 hours
• Screening of high-risk groups for Hepatitis B and C
• Hepatitis B vaccination for healthcare workers and eligible high-risk groups
• Uses existing TB molecular testing machines for hepatitis diagnosis
• Refers Hepatitis B and C-positive blood donors for treatment

What Is Hepatitis?

Hepatitis is inflammation of the liver caused by viruses, alcohol, certain drugs, toxins, or autoimmune diseases. Hepatitis B and C are the most common causes of chronic liver disease and can lead to cirrhosis and liver cancer if left untreated.

World Hepatitis Day 2026

World Hepatitis Day is observed each year on 28 July to raise awareness of viral hepatitis.

The World Hepatitis Day 2026 theme, “Hepatitis: Let’s break it down,” is a call to remove the barriers that stand between people and the services that can save their lives. Viral hepatitis continues to be a major cause of preventable illness and death worldwide.
