WHEN a respiratory virus like Human Metapneumovirus (HMPV) spreads, many inadvertently only focus on coughs, fevers, and congestion — but your heart might be quietly at risk too. Viruses don't just affect your lungs; they can also stress your cardiovascular system, especially if you already live with heart disease, hypertension, or diabetes. Fortunately, a few practical steps can go a long way in protecting your heart health during viral outbreaks.To help navigate these health threats during a viral outbreak, Dr G.S. Sridhar, a Consultant Cardiologist and Physician from Sri Kota Specialist Medical Centre , offers essential advice for protecting your heart both individually and at the community level. Here are 10 ways you can take proactive steps to support your cardiovascular health when viruses are spreading. Dr G.S. Sridhar, a leading voice in cardiology and public health, offers essential advice for protecting your heart both individually and at the community level.
Stay Up to Date with Vaccinations Vaccines against viruses like influenza, pneumonia don't just help prevent infection — they also reduce the risk of virus-triggered cardiac events.If you're in a high-risk group, staying current with your shots can prevent serious complications that can burden the heart and simultaneously avoid risk of respiratory infections such as HMPV that currently have no specific vaccine available.On a broader-level, Dr Sridhar also highlights the importance of accessible healthcare for the citizens, particularly during a viral outbreak.'Ensuring increased access to free or affordable flu and pneumonia vaccines, especially for high-risk populations, is also crucial.' he stated.

Manage Pre-Existing Conditions Diligently Chronic issues like hypertension, diabetes, and high cholesterol can escalate your risk of severe outcomes during infections.Regular check-ups, medication adherence, and lifestyle changes are key to keeping these conditions under control, especially when your immune system is under attack.
Eat a Heart-Healthy Diet As the saying goes, 'You are what you eat,' and with that, fuel your body with nutrient-dense foods that support immunity and cardiovascular function. Focus on fruits, vegetables, whole grains, lean proteins, and heart-healthy fats like those found in fish, nuts, and olive oil.Alternatively, cut down on salt and processed foods to avoid increasing blood pressure and inflammation.
Exercise Regularly — Even Indoors Physical activity helps lower blood pressure, strengthen the heart, and enhance immune function in order to fully prepare for any impending viral outbreaks.You don't need a gym — bodyweight workouts, yoga, or even household chores can keep you moving. Aim for at least 150 minutes of moderate activity each week.
Prioritise Sleep and Stress Management Poor sleep and constant stress can also lead to weakened immune systems and contribute to inflammation, increasing strain on your heart.It is advised to prioritise rest by keeping a consistent sleep schedule and managing anxiety through relaxation techniques like breathing exercises, meditation or journaling.
Avoid Smoking and Limit Alcohol Intake Smoking inflames blood vessels and impairs lung function, compounding the risks during respiratory infections. Alcohol, especially in excess, can raise blood pressure and disrupt heart rhythm. Cutting down on both improves heart and lung resilience, making sure it is ready to ward off respiratory viruses.

Stay Hydrated and Nourished Don't underestimate the power of proper hydration and regular meals. Water is essentially the lifeblood of the human body, supporting each and every organ system, including your heart.'Stay hydrated, get enough rest, and maintain good nutrition, all of which are key in preventing further complications,' Dr Sridhar noted.Skipping meals or relying on sugary or processed snacks, while also drinking carbonated drinks instead of clean water can spike blood sugar and blood pressure — both of which can worsen heart issues during an illness.

Monitor Symptoms Early and Don't Delay Care If you or a loved one experience chest pain, unusual fatigue, or shortness of breath, it is advised to seek medical help immediately.Viral infections can sometimes trigger inflammation of the heart muscle, known as myocarditis, or lead to heart failure. Early medical intervention could very well save your life.
Minimise Exposure to Viruses Masks, hand hygiene, and physical distancing remain essential tools in avoiding infection, especially in crowded indoor settings where bacterial infections and airborne viruses may run rampant.'Avoid exposure by wearing a mask, maintaining physical distance, and practicing good hygiene,' Dr Sridhar advised.These small habits can make a big impact in minimising risk to exposure, particularly if you, loved ones, or acquaintances are immunocompromised.
Keep in Touch With Your Doctor Don't skip appointments or delay follow-ups — even if they're virtual. Continue your prescribed medications, and let your doctor know if you notice new or worsening symptoms.'Continue your cardiac medications and do not delay any necessary care,' Dr Sridhar reminded.
A viral outbreak doesn't have to become a cardiac emergency — but awareness and action are critical. By staying proactive and following medical advice, you can help protect both your heart and the well-being of your entire community.

Number of obese and overweight teenagers predicted to rocket
In a major new review of the health and wellbeing of adolescents, experts said some main drivers of ill-health among teenagers have switched from cigarettes and alcohol to weight gain and mental health problems. 01 Jun 2025 08:02am In a major new review of the health and wellbeing of adolescents, experts said some main drivers of ill-health among teenagers have switched from cigarettes and alcohol to weight gain and mental health problems. - Photo illustrated by Sinar Daily LONDON - Almost half a billion teenagers around the world will be overweight or obese by 2030, experts predicted as they warned that adolescent health is at a "tipping point', PA Media/dpa reported. In a major new review of the health and wellbeing of adolescents, experts said some main drivers of ill-health among teenagers have switched from cigarettes and alcohol to weight gain and mental health problems. They warned that mental health among teenagers has seen a "significant decline' over the past three decades, which was exacerbated by the Covid-19 crisis. And they projected that 464 million teenagers around the world will be overweight or obese by 2030 - 143 million more than in 2015. But the Lancet Commission on Adolescent Health and Wellbeing pointed out: "In terms of health risks, substance use (specifically tobacco and alcohol) has declined in every region.' The experts on the commission said action is needed to tackle threats to adolescents' health and wellbeing. They warned that progress in teenage health has "lagged well behind' the improvements that have been made in the health and development of young children - with these benefits being at risk of being "undermined' with increased ill-health in teenagers. They added that current funding is "not proportionate with the magnitude of the challenge'. They wrote: "Adolescence can no longer be ignored... the time to act is now.' The authors of the report also highlighted how the shift towards a "more digital world' could have a "profound impact on young people's future health and wellbeing'. But they warned against "overly restricting' access, saying there needs to be a balance, highlighting that the online world offers teenagers new opportunities for social interaction, education, employment and health promotion. Meanwhile, they pointed out that this generation of teenagers is the first to grow up among harsher climate conditions. "Today's adolescents are the first cohort of humans who will live their entire life experiencing the growing reverberations of climate change,' they wrote. Commission co-chairwoman Professor Sarah Baird, from George Washington University in the US, said: "The health and wellbeing of adolescents worldwide is at a tipping point, with mixed progress observed over the past three decades. "Whilst tobacco and alcohol use has declined and participation in secondary and tertiary education has increased, overweight and obesity have risen by up to eight-fold in some countries in Africa and Asia over the past three decades, and there is a growing burden of poor adolescent mental health globally. "Additionally, the challenges faced by the world's adolescents are at risk of being exacerbated by emerging global issues including climate change, world conflicts and a rapid transition to a more digital world. "Investing in the health and wellbeing of young people is crucial for safeguarding our collective future.' The authors of the commission's report point out that "investment in adolescent health will become increasingly important throughout the 21st century', adding: "As populations age and fertility rates fall in even the poorest countries, ensuring the health and wellbeing of adolescents will be crucial to all countries' health and prosperity.' - BERNAMA-PA Media/dpa More Like This

High time for government hospitals to introduce IORT for early cancer detection
At the moment, IORT is only available in university hospitals and private hospitals. Photo illustrated by Sinar Daily It is time for government hospitals to include intraoperative radiation therapy (IORT) in their services, said Tun Dr Hasmah Mohd Ali. She emphasised the need for accessible cancer treatment options, particularly for women who are diagnosed with early-stage breast cancer. "Government hospitals should have IORT facilities because there are so many women out there who need them,' she said while sharing her experience as breast cancer survivor at Prince Court recently. According to Prince Court Medical Centre Consultant Breast and Endocrine Surgeon Dr Harjit Kaur, IORT is not available in government hospitals. "At the moment, IORT is only available in university hospitals and private hospitals. It's a costly piece of equipment, but it is highly effective for early cancer cases. It's about time the government considers equipping hospitals with this technology," she said. IORT is a form of targeted radiation therapy delivered directly to the tumor site during surgery. It is particularly effective for small tumors less than three cm in size and in cases where lymph nodes are negative. Dr Harjit explained that it is ideal for strongly hormone-positive and HER2-negative cancers in women over the age of 45. One of the major advantages of IORT is its ability to cut down waiting times and reduce the duration of external radiation therapy. 'Women often wait for weeks or months for radiation treatments. With IORT, we can significantly shorten that time,' Dr Harjit said. In cases where patients do not fully meet the criteria for IORT, it can still be used in conjunction with external radiation therapy to reduce the overall treatment duration. 'Instead of five weeks, external radiation can be shortened to two weeks when combined with IORT,' she explained. Moreover, IORT offers nearly equal results to external beam radiation therapy while causing fewer side effects. 'It's a very useful tool, but not everyone is suitable for it. That's why careful evaluation of the tumor type, biology and patient age is critical,' Dr Harjit added. The introduction of IORT in government hospitals could be a game-changer for cancer care in Malaysia. By investing in this technology, the government can ensure that women from all walks of life have access to effective and timely treatment for early-stage cancers. 'The results show that IORT is the way forward. We urge the government to consider this seriously and make these facilities available in government hospitals,' Dr Harjit said. More Like This

Ditch traditional cures, prioritise early cancer detection
Dr Siti Hasmah attributed her courage and determination to the steadfast support of her husband, former two-time Prime Minister Tun Dr Mahathir Mohamad. Never believe in traditional 'bomohs' or 'tok bidan' who claim they have cures for cancer. It's disheartening that many still trust these methods and dismiss professional medical advice, advises Tun Dr Hasmah Women must move away from relying on traditional medicine for cancer treatment and instead prioritise professional medical care, advises Tun Dr Hasmah Mohd Ali. Drawing from her own experience with breast cancer, she cautioned that seeking unverified treatments from traditional healers, or 'bomohs' and 'tok bidan,' only delays crucial medical intervention. "Never believe in traditional 'bomohs' or 'tok bidan' who claim they have cures for cancer. It's disheartening that many still trust these methods and dismiss professional medical advice. "The Malay community, in particular, is deeply affected by this reliance on traditional cures," she shared during a talk at Prince Court Medical Centre last week. Dr Hasmah recounted her journey overcoming breast cancer to highlight the importance of prompt medical consultation. 'It all begins with awareness and taking responsibility for our health. Women must understand that early detection not only saves lives but ensures better outcomes," she stated. She urged women to schedule annual check-ups, including mammograms and ultrasounds, as these screenings are vital for early detection. "If something feels wrong, don't ignore it. Take action immediately. A simple pain or lump could be a sign and waiting only makes things worse," she added. Photo illustrated by Sinar Daily Prince Court Medical Centre Consultant Breast and Endocrine Surgeon Dr Harjit Kaur described that most breast cancers are painless, which can make them particularly insidious. Often, by the time symptoms appear and patients seek help, it may be too late. "Early detection through screenings like mammograms and ultrasounds is vital. These procedures are straightforward and could save countless lives," she said. Dr Hasmah also addressed the stigma surrounding breast cancer, observing that shame and fear continue to prevent women from seeking medical attention. 'Women often hesitate because the affected area is private, or they are scared of what the doctor might confirm. But if God has given us the pain, He has also given us the remedy. It is our responsibility to find that solution," she added. She commended young women who use reliable internet sources to educate themselves and confidently seek medical advice. 'There is a positive shift among the younger generation. Many are proactive, asking doctors the right questions and taking charge of their health,' she added. Reflecting on her personal battle, Dr Hasmah attributed her courage and determination to the steadfast support of her husband, former two-time Prime Minister Tun Dr Mahathir Mohamad. "When the doctor brought the positive diagnosis report to my house, my husband was disappointed that I hadn't told him earlier. But he was proud of my determination to get well. His support meant the world to me," she added. Dr Hasmah passionately urged women to make their health and well-being a top priority in their lives. She emphasised the importance of overcoming fear and stigma, encouraging women to be proactive about their health. "To all women out there, don't be afraid. Seek help, get your check-ups, and take charge of your health. If you want a happy and long life with your family, fear and shame have no place in this journey," she said.
