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.

Amid rising obesity, early diabetes risk, and mental health issues among children, India has expanded its child health screening program to include behavioral disorders and non-communicable disease (NCD) risk factors.
The Ministry of Health and Family Welfare rolled out the screening measures under the revised Rashtriya Bal Swasthya Karyakram (RBSK) 2.0 guidelines.
The guidelines include steps to address mental health conditions and early risk factors for diseases such as diabetes and hypertension. These were released at the recently concluded National Summit on Good Practices and Innovations in Public Healthcare Service Delivery.
The screening services are free and will be delivered through mobile health teams at Anganwadi centers and schools, ensuring universal outreach and early identification.

Children with Type 1 Diabetes Mellitus can develop diabetic ketoacidosis (DKA) if it is not diagnosed on time, since they are insulin-dependent.
Dr. Archana Arya, Senior Consultant Pediatric & Adolescent Endocrinologist at the Institute of Child Health, Sir Ganga Ram Hospital, New Delhi, told HealthandMe that DKA requires hospitalization for treatment, and if undiagnosed, it can lead to coma and death. Early diagnosis reduces morbidity and hospital admissions.
These children present with typical symptoms such as
Type 2 Diabetes Mellitus may or may not present with typical symptoms, and children may develop long-term complications such as retinopathy and nephropathy if the condition goes undiagnosed for a prolonged period.
All overweight and obese children, especially those with a family history of Type 2 diabetes, those with acanthosis nigricans (thickened and dark skin behind the neck and underarms), and girls with PCOS are at high risk of developing Type 2 diabetes and should be screened annually to prevent complications.
The expert added that children with diabetes are at a higher risk of depression (2–3 times higher prevalence), anxiety, and suicidal ideation (in 8–27 percent of youth) due to dietary restrictions and the burden of multiple insulin injections in Type 1 diabetes. Diabetic youth are 1.7 times more likely to attempt suicide, often through insulin overdose.
Dr. Seema Dhir, Unit Head & Senior Consultant, Internal Medicine, Artemis Hospitals, told HealthandMe that good health in early life is essential for preventing non-communicable diseases such as obesity, diabetes, and heart disease. Diabetes is often linked to poor lifestyle and health choices.
Early monitoring, detection, and effective management can reduce the growing burden of diabetes.
Dr. Munia Bhattacharya, Senior Consultant – Clinical Psychology, Mental Health and Behavioural Sciences, Marengo Asia Hospitals, Gurugram, emphasized that preventing non-communicable diseases like diabetes, heart disease, and obesity begins with maintaining both mental and physical well-being.
Providing mental support to children helps them cope better with stress and reduces the risk of anxiety, depression, and suicidal thoughts.
Children who are encouraged to express their feelings and seek help are less likely to experience anxiety, depression, and suicidal tendencies. Early awareness also builds coping skills, decision-making abilities, and healthier lifestyles—paving the way for long-term well-being and a more balanced, confident future.
Pembrolizumab is effective for cervica, breast, and lung cancer treatments. (Photo credit: AI generated)
Cancer treatment is often viewed as months of painful chemotherapy, radiotherapy, and surgeries that one might physically recover from but may continue to struggle with the trauma of for years. But now, thanks to a new injectable drug, cancer treatment may speed up for thousands of NHS patients in the UK. Pembrolizumab, also known as Keytruda, is that one-minute cancer drug injection that will likely speed up cancer treatment for thousands of patients—and soon, it will be available as a quicker jab instead of a half-hour drug.
Pembrolizumab is an injectable drug prescribed to over 14,000 people in Britain every year. It works by stimulating the immune system to attack cancer cells on its own. Patients usually spend about two hours at a clinic when it is slowly administered for 30 minutes or more via a drip or IV line. However, this one-minute jab is now available in an injectable form and can be administered every three weeks or as a two-minute injection every six weeks.
The drug has now been made more concentrated, with an extra component added to help the body absorb it faster. This shot is given in the stomach or the thigh instead of being infused through a vein in the arm. Doctors say that this rapid jab, which takes less than a minute to deliver, can help patients get back to their lives without having to spend hours in a hospital chair; for a cancer patient, regular hospital trips and multiple rounds of therapy can be physically exhausting and mentally draining.
Pembrolizumab, according to doctors, will make cancer therapy and treatment more convenient for patients, and it can also bring down waiting times. It is one of the most successful cancer drugs and has been celebrated as a game-changer in treating several tumour types. The NHS uses the drug to treat 14 types of cancer, such as lung, breast, bowel, womb, stomach, head and neck, and melanoma.
The first-ever patient to receive pembrolizumab was Shirley Xerxes, 89, from St Albans, Hertfordshire, who was suffering from bowel cancer. She spoke several times about how it changed her will to live and how little time it took.
Pembrolizumab tells the immune system to recognise and kill cancer cells. It can fight head and neck, lung, breast, and cervical cancer. The drug is administered every three weeks as a one-minute injection, or it is given every six weeks as a two-minute injection, depending on the cancer type.

The World Health Organization (WHO) said on May 3 that three people who died aboard a cruise ship in the Atlantic Ocean were suspected to have been infected with hantavirus. The rodent-borne virus can cause severe and sometimes fatal respiratory illness.
"To date, one case of hantavirus infection has been laboratory confirmed, and there are five additional suspected cases," the organization said in a post on social media platform X.
"Of the six affected individuals, three have died, and one is currently in intensive care in South Africa," it added.
In a statement provided to USA TODAY, Netherlands-based expedition cruise operator Oceanwide Expeditions said it was addressing a "serious medical situation" on board m/v Hondius. The ship was en route from Argentina to Cape Verde, an island nation off Africa's west coast.
According to the Centers for Disease Control and Prevention (CDC), hantaviruses are a family of viruses that can cause severe illnesses and even death. The hantavirus is primarily spread by rodents through
The CDC notes that hantaviruses are capable of causing diseases like hantavirus pulmonary syndrome or HPS and hemorrhagic fever with renal syndrome or HERS.
It can infect and cause serious diseases in people. It has mainly two syndromes. One is found in the Western Hemisphere, including in the US, which can cause HPS.
The most common hantavirus that causes HPS in the US is spread by the deer mouse. HERS is a group that is similar to illnesses caused by hantaviruses and is found mostly in Asia and Europe. There's another type, called the Seoul virus, which is a type of hantavirus that causes HERS and is found worldwide, including in the US.
The WHO did not specify the type of hantavirus or syndrome in the cruise incident, but did mention respiratory risks.
According to the CDC, symptoms can appear one to eight weeks after exposure, initially presenting fatigue, fever, and muscle aches. As the disease progresses, it can cause coughing, shortness of breath, and chest tightness as fluid accumulates in the lungs.
The CDC reports that about one-third of individuals who develop respiratory symptoms from the disease may not survive.
Despite extensive research, many questions remain unanswered, including why some cases are mild while others become severe and how antibodies develop. She and other researchers have been tracking patients over extended periods, hoping to uncover potential treatments.

You can reduce your risk by eliminating and minimizing your contact with rodents in your home, workplace, or campsite. The best way is to seal holes and gaps in your home or garage and keep the rodents from entering your home. You can also place traps in and around your home to decrease rodent infestation. Clean up any easy-to-get food that could attract rodents.
CDC notes that the diagnosis in a person who has been infected for less than 72 hours is difficult. If the initial test is done before the virus can be found, then a repeat test is required after 72 hours whenever the symptoms start to show up. Early symptoms, as mentioned above, like fever, headache, muscle aches, nausea, and fatigue, could also be easily confused with influenza, thus a test is extremely important.
