The main cause of death globally is still heart disease. Heart attacks may occur suddenly without any warning signs. However, in the film industry, intense chest pain would be portrayed for a heart attack. In actuality, many patients have slight symptoms that go unnoticed until the time of their heart attack days or even weeks prior to that.
Heart attacks do not always announce themselves with dramatic chest pain. Often, they manifest in subtle, easy-to-dismiss ways. Recognizing these overlooked warning signs and taking proactive steps toward cardiovascular health can save lives. If you or someone you know experiences any of these symptoms, seeking immediate medical care is crucial. Prioritizing heart health today can help prevent life-threatening complications in the future.
1. Discomfort Pressure in the Chest
One of the earliest and most common warning signs of an impending heart attack is pressure, tightness, or fullness in the chest. This pain is not typically sharp and sudden, like most people associate with a heart attack, but it can be intermittent, coming in waves, and lasting for several minutes before fading away. According to the American Heart Association, this is one of the red flags when accompanied by exertion. If you have persistent chest pressure, you should call emergency services immediately.
2. Pain Radiating to Other Parts of the Body
The well-known symptom of chest pain can also manifest discomfort related to a heart attack as pain radiating to other parts of the body. It is not unusual for people experiencing this kind of heart attack to report feeling pain in the shoulders, arms, back, neck, and even jaw. The vagus nerve is one that connects the heart to the brain, abdomen, and neck. The pain may be referred to these regions. In case you experience a sudden, unexplained pain in these regions, especially when exercising, seek a doctor's opinion.
3. Dizziness and Lightheadedness
Feeling dizziness upon standing up quickly or missing a meal is common, but unexplained dizziness often with chest pain or shortness of breath is the first sign of heart attack. Sudden hypotension can seriously decrease the blood supply to the brain and cause dizziness. Dizziness that does not go away on its own should not be ignored.
4. Unexplained Fatigue
It often happens that excessive tiredness, particularly in a busy lifestyle, is considered trivial, but ongoing fatigue, mostly in women, is a predictor of heart failure. According to some studies, extreme fatigue often starts a month before a heart attack, primarily in women. This is simply because the heart cannot pump well enough, leaving insufficient oxygen available to muscles and organs. Consult a healthcare professional if you become increasingly tired over time, yet are getting all the rest in the world.
5. Nausea, Indigestion, or Stomach Pain
Digestive problems like nausea, vomiting, or indigestion are often mistaken for acid reflux or food poisoning. However, these symptoms can also indicate reduced blood flow to the digestive tract, a common precursor to heart attacks. If you experience gastrointestinal distress alongside other symptoms like dizziness or chest discomfort, it's important to seek medical advice immediately.
6. Cold Sweats and Excessive Perspiration
Without apparent reason, a heart attack might be signaled by sudden sweating without any exercise or hot weather conditions. The heart's inability to function properly creates the body's "fight or flight" reaction, which means excessive sweating will occur. Be aware of your body and never ignore a cold sweat, particularly if it coincides with other symptoms.
7. Heart palpitations or irregular heartbeat
A racing or irregular heartbeat can be a normal reaction to stress or caffeine consumption. However, regular or unprovoked heart palpitations may indicate that the heart is under duress. If the heart is not getting enough oxygen-rich blood, it can start to beat irregularly. If you experience palpitations along with dizziness, chest pain, or shortness of breath, you should see a doctor right away.
8. Shortness of Breath
If suddenly climbing stairs or performing other everyday activities becomes a problem, then there may be a heart issue. Shortness of breath usually occurs with heart conditions because the circulation is not adequate and less oxygen is provided to the lungs. This symptom can occur either with or without chest pain and is an important indicator of the presence of underlying heart disease. If you find yourself experiencing sudden unexplained breathlessness, then seek a healthcare provider as soon as possible.
Early detection of these symptoms and early intervention can help avoid a life-threatening heart attack. You should visit a doctor if you feel the following symptoms:
Although heart attacks may come out of nowhere, lifestyle plays an important role in reducing a patient's risk; here are some heart-healthy habits to consider:
Take on a Heart-Healthy Diet: Focus on consuming whole foods, lean proteins, healthy fats, and fiber-rich fruits and vegetables. Try to limit processed foods, saturated fats, and added sugars.
Stay Active: Engage in at least 30 minutes of moderate physical activity most days of the week to strengthen your heart and improve blood circulation.
Smoking. Smoking is probably the single largest risk factor for heart disease. If you are a smoker, quitting can easily be the single best thing you can do to improve your heart health.
Deal with Stress: Chronic stress leads to heart disease. Relaxed people through various relaxation techniques including yoga, meditation, and even deep breathing, have lesser stresses.
Regular health checks Monitor blood pressure, cholesterol levels, and blood sugar on a regular basis. The risk factors' early detection can help avoid serious complications.

Breastfeeding is important not only for babies' health and nutrition but also for protecting mothers from serious diseases, the World Health Organization (WHO) said.
It urged governments to strengthen access to services and interventions that support breastfeeding as part of World Breastfeeding Week, observed annually from August 1–7.
The 2026 theme, "Breastfeeding for a Sustainable Start in Life: Strengthen What Works," focuses on tracking progress, evaluating impact, and scaling proven approaches that improve breastfeeding outcomes.
"Scaling up breastfeeding could prevent almost 400,000 child deaths and around 140,000 maternal deaths each year," said UNICEF Executive Director Catherine Russell and WHO Director-General Dr. Tedros Adhanom Ghebreyesus in a joint statement.
"Every US$1 invested in breastfeeding promotion generates an estimated US$59 in economic returns through lower health-care costs, improved cognitive development, higher educational attainment, and increased lifetime earnings," they added.
The experts noted that breastfeeding is one of the simplest and most powerful ways to protect a child's health. It provides infants and young children with essential nutrition, boosts immunity, helps protect against serious illnesses, and supports cognitive development.
For mothers, breastfeeding also offers significant health benefits by reducing the risk of noncommunicable diseases such as breast and ovarian cancers, and type 2 diabetes.
The WHO said breastfeeding rates have improved globally due to sustained investments in policies and programs supporting mothers and families.
Exclusive breastfeeding during the first six months increased from around 37 per cent in 2012 to more than 47 per cent today. Over the past five years, the prevalence of breastfeeding up to two years of age has risen from 38 per cent to 50 per cent.
Despite these gains, the WHO said many countries continue to lag behind global targets.
"Coverage of services supporting breastfeeding remains low, policies are inconsistently enforced, and service quality is often inadequate, especially in low-income, fragile, and humanitarian settings," the WHO said.
The agency noted that cost-effective interventions include skilled breastfeeding support within health systems, community-based counselling, maternity protection policies, and protection from the exploitative marketing of commercial milk formulas.
WHO and UNICEF called on governments, health systems, workplaces, communities, civil society organizations, and families to strengthen the "Warm Chain of Support" for breastfeeding.
During World Breastfeeding Week, the agencies urged countries to:
"Breastfeeding is vital. By investing in proven solutions, we can give every child the best possible start in life and ensure every mother gets the care and services she needs," the agencies said.

A new study published in The Lancet Regional Health–Southeast Asia has found that India accounts for 68% of all childhood cancer cases in the SAARC region.
While the country's large child population contributes to the high numbers, experts say underdiagnosis and incomplete cancer registration may mean the actual burden is even greater.
An international team of researchers, including from the US, India, and Canada, estimated that nearly 37,700 children aged up to 14 years were diagnosed with cancer across South Asia in 2022, with 17,700 deaths reported. India alone accounted for an estimated 25,939 cases and 12,028 deaths.
The researchers noted that because cancer registration remains incomplete, particularly in rural areas, the true number of childhood cancer cases in India could exceed 50,000 annually.
India is home to more than 380 million children, accounting for nearly 69% of the child population in the SAARC region. This naturally contributes to the country's higher share of childhood cancer cases and deaths.
However, experts emphasize that population size is only part of the explanation. Delayed diagnosis, limited access to specialized treatment, and gaps in cancer registration continue to affect both disease estimates and patient outcomes.
Dr. Narendra Agrawal, a leading Hematologist and Bone Marrow Transplant Physician and Senior Consultant and Unit Head of Haemato-Oncology at Rajiv Gandhi Cancer Institute & Research Centre, told HealthandMe that childhood cancer remains a major public health concern in India.
"Current estimates suggest that around 70,000–80,000 children and adolescents develop cancer each year, although the exact number remains uncertain due to expanding cancer registration systems". The most common childhood cancers in India include:
Unlike many adult cancers, most childhood cancers do not have a clearly identifiable or preventable cause. Dr. Agrawal explained that, in most children, cancer develops because of genetic changes that occur during early development. These changes are usually not linked to lifestyle factors or inherited from parents.
Although the causes of most childhood cancers remain unclear, some well-established risk factors include:
Dr. Agrawal said India's substantial childhood cancer burden is largely driven by its population size. However, improving outcomes requires addressing several systemic challenges.
Key issues include:

Marketed as a "harmless" alternative to cigarette smoking, vaping is increasingly emerging as a health concern, particularly for lung health, doctors warned ahead of World Lung Cancer Day on August 1.
Traditional cigarettes remain strongly linked to lung cancer, chronic obstructive pulmonary disease (COPD), and several other life-threatening illnesses. However, growing laboratory, animal, and population studies suggest vaping may also damage lung tissue, alter DNA, and potentially increase lung cancer risk—especially among people who both smoke and vape.
A recent study published in the peer-reviewed journal ERJ Open Research found that vaping may offer far less protection than many users believe when it comes to cardiovascular fitness, breathing efficiency, lung function, and blood vessel health in young adults.
"E-cigarettes are often advertised as a safer choice and as a way to help people quit smoking. But the evidence behind these claims is weak. We still don't fully know what long-term damage e-cigarettes can do to the lungs, including whether they can cause lung cancer," Dr. Shiba Kalyan Biswal, Head of Pulmonology at Shalby International Hospital, Gurugram, told HealthandMe.
The vapor produced by e-cigarettes contains several harmful chemicals, including substances that can damage cells and DNA—the genetic material inside the body's cells.
Animal studies have found that mice exposed to e-cigarette vapor for about a year developed a type of lung cancer. Ingredients commonly used in e-cigarette liquids, such as propylene glycol and benzoic acid, may also irritate cells and trigger inflammation in the lungs.
"There have also been outbreaks of a serious vaping-related lung disease that has sent people to hospital with severe breathing problems. This shows that the risks of vaping can be unpredictable, especially when products are poorly regulated or contain unknown ingredients," Dr. Biswal explained.
She urged doctors to routinely ask patients about e-cigarette use, particularly those with breathing problems or those at higher risk of lung cancer.
"Since evidence suggests that e-cigarettes add to the risk for people who used to smoke, it may be worth including vaping history when deciding who needs lung cancer screening," she said.
According to Dr. Biswal, lung cancer risk appears to be even higher among people who use both e-cigarettes and conventional cigarettes, often referred to as "dual users."
Many smokers who turn to e-cigarettes intending to quit end up continuing to use both products rather than switching completely.
"This means they stay addicted to nicotine and may be exposed to even more harmful substances."
Doctors are also reporting more lung cancer cases among young people who have never smoked, particularly women.
Indoor air pollution, biomass fuel exposure, second-hand smoke, occupational hazards, and genetic susceptibility are increasingly contributing to the disease, said Dr. Akshay Budhraja, Senior Consultant and Head of Respiratory and Sleep Medicine at Aakash Healthcare.
"It's no longer just the lifelong smoker in his sixties—we are seeing younger patients, more women, and a growing number who have never touched a cigarette. Air quality, occupational exposure and genetic predisposition are all playing a bigger role than they used to, and that means our screening approach has to widen well beyond the traditional smoker profile," Dr. Budhraja said.
Experts said early detection through low-dose CT screening remains crucial for high-risk individuals. However, symptoms such as a persistent cough or breathlessness are often mistaken for pollution-related irritation or a lingering infection, leading many people to delay getting screened.
They also noted that lung cancer affects more than the lungs, with potential impacts on men's sexual health and women's reproductive health.
According to the World Health Organization (WHO), lung cancer remains one of the world's biggest public health challenges due to its high incidence and mortality. In 2024, it was the leading cause of cancer-related deaths globally, with an estimated 2.6 million new cases and 1.8 million deaths.
Lung cancer develops when abnormal cells grow uncontrollably in the lungs. Treatment depends on a person's medical history and the
stage of the disease.
The doctors stressed that avoiding tobacco remains the most effective way to reduce lung cancer risk.
"Smokers face nearly 20 times the risk of non-smokers, though the rising non-smoker caseload complicates that picture," said Dr. Budhraja. "Second-hand smoke is the third leading cause of lung cancer among non-smokers; radon gas, seeping in from soil, is the leading one, and home testing kits can catch it."
