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.

Metformin is a safe and effective drug used by type 2 patients for the last six decades to control their blood sugar levels and improve the way the body handles insulin.
A recent study showed that metformin can also be crucial in reducing the risk of vision loss in people over the age of 50, known as age-related macular degeneration (AMD).
The observational study, published in the BMJ Open Ophthalmology, showed that metformin can cut down the cases of AMD by nearly 40 percent in people with Type 2 diabetes over five years.
“We have found a significant association between metformin use and a reduction in the incidence of intermediate AMD by 37 percent in people with diabetes over 5 years. Previous epidemiological studies of metformin and AMD have used secondary data on AMD,” said corresponding author Nicholas A. V. Beare, from the University of Liverpool, UK.
“Given metformin’s anti-aging therapeutic effects, the reduction in risk is plausible and warrants prospective clinical trials,” he added.

While currently there is no specific treatment option for AMD — a common cause of blindness in high-income countries — scientists have shown interest in metformin as a candidate drug for treating AMD and reducing its progression.
It is because of metformin's antioxidant, anti-inflammatory, antiangiogenic, and antifibrotic effects. Metformin is also postulated to delay ageing and ageing-related diseases.
Previous research has also identified metformin as a potential treatment for all stages of AMD. Researchers also noted that the common diabetes drug is readily accessible and has a strong safety profile.
The BMJ study analyzed more than 2,500 participants aged 50 or above who attended retinopathy screening in 2011.
All participants had Type 2 diabetes and gradable fundus photographs — high-quality retinal images.
Individuals prescribed oral metformin had a 37 percent lower risk of intermediate AMD by five years. The results are consistent with known biological mechanisms, given metformin’s potential favourable effects on AMD progression, researchers reported, the researchers said.
The team, however, acknowledged limitations such as a lack of proper data regarding the dose, duration of prior use, or compliance with metformin use.
Further, there were only a relatively small number of participants developing advanced AMD – an inevitability in population-based studies. They urged for a clinical trail to prove metformin's potential in treating AMD.

Age-related macular degeneration (AMD) is a disease of the retina. It happens when a part of the retina called the macula is damaged. It results in the loss of sharp, straight-ahead vision.
The condition commonly affects adults over 50, and causes
While AMD rarely causes total blindness but affects central vision, making reading and driving difficult. It is of two types:

Harry Potter star Daniel Radcliffe has quit smoking after 20 long years. The reason: his two–year–old son with girlfriend Erin Darke.
Speaking to media outlet Vulture, the 36-year-old English actor shared that after becoming a father, he was inspired by intrusive thoughts about his mortality, which enabled him to quit the deadly habit after two decades.
"I smoked for 20 years pretty heavily, and I was never even thinking about quitting, and then shortly after having my son, the intrusive thoughts of my own death really helped as an incentive to quit," Radcliffe was quoted as saying.
Radcliffe also shared how a book -- The Easy Way to Quit Smoking, by Alan Carr -- helped him decide to quit smoking.
"It may not work for everybody, but it really worked for me," noted the star, currently starring in the Broadway play Every Brilliant Thing.
Earlier this month, the actor spoke with WSJ Magazine and shared that from being on “cigarettes all day”, he's transformed into a fitness freak.
Smoking can affect all organs in our body. While lung cancer and tuberculosis are the most prominent ones, smoking can seriously increase the risk of several chronic diseases. These include:
While quitting tobacco is important, it is a difficult task, with some people finding it harder to quit than others. It may be important to seek help quitting.

These strategies have shown varying levels of success in aiding smokers to quit permanently. In addition, alternative methods like e-cigarettes and mindfulness-based techniques have gained traction in helping reduce smoking addiction.
Behavioral Support
Quitting smoking isn’t just about resisting cravings. Often, behavioral support through counseling or therapy is crucial for tackling the psychological aspects of addiction. Behavioral therapy involves working with a trained professional to identify triggers, develop coping strategies, and create a tailored quit plan. Research shows that combining counseling with other quit methods can significantly increase success rates.
Prescription Medications
Some medications, such as varenicline (Chantix) and bupropion (Zyban), have been shown to help people quit smoking by reducing cravings and withdrawal symptoms. Experts suggest that varenicline works by blocking the effects of nicotine in the brain, while bupropion is an antidepressant that helps manage withdrawal symptoms. Both medications are generally more effective when combined with behavioral therapy.
Nicotine Replacement Therapy (NRT)
Nicotine replacement products, such as nicotine patches, gums, lozenges, and nasal sprays, deliver controlled amounts of nicotine to ease withdrawal symptoms. According to experts at Harvard Health, NRT can double the chances of quitting by alleviating physical cravings while the person works on overcoming the psychological addiction.

About 10.6 percent –15 percent of India's population suffers from some form of mental health conditions, with 15 percent of the adult population also requiring active intervention.
To enable researchers to gather as well as systematically document data on patients with major forms of mental illness, neuroscientists in India have developed CALM-Brain — a digital repository of data on brain structure and function from a range of psychiatric disorders.
CALM-Brain contains data from over 2,000 participants from 900 families across the country.
CALM-Brain will help clinicians and researchers
“CALM-Brain was conceived as a method to assemble data from multiple scales of analysis of brain structure and function on a single platform. We believe that the application of modern methods of data analysis to this dataset will help bridge the gap between these scales of analysis,” said Prof. Raghu Padinjat, CBM co-ordinator at CBM-NCBS, in a statement.

CALM-Brain is the result of collaborative efforts of researchers at the Rohini Nilekani Centre for Brain and Mind (CBM) — a partnership between the National Institute of Mental Health and Neuro Sciences (NIMHANS) and the National Centre for Biological Sciences (NCBS) - TIFR.
CALM-Brain is India’s first-of-its-kind repository of clinical, neuroimaging, behavioral, genetic, and other datasets on disorders such as:
The dataset is also linked to a biorepository of stem cells, which can be used to perform biological research in psychiatry to understand the origins of such severe mental illnesses.
“The primary goals of the project are to identify biological markers of severe psychiatric illnesses, which cut across traditional diagnostic frameworks. In addition, we will try to identify fundamental biological mechanisms of the disease and medication response,” said Prof. Y.C. Janardhan Reddy, CBM coordinator at CBM-NIMHANS.
Mental wellness is a major health and economic concern in India. The World Health Organization (WHO) estimates India’s economic loss due to mental health conditions to be USD 1.03 trillion (2012-2030).
Recently, health experts and policymakers, as part of the government-led Post-Budget Webinar series, highlighted the growing burden of mental and neurological disorders in India and also stressed the urgent need to strengthen institutional capacity to meet emerging healthcare demands.
"One in seven Indians is affected by mental health disorders, while several states continue to face a treatment gap ranging from 70 to 90 percent," the experts said.
They added that "neurological and mental health conditions are among the leading contributors to disability-adjusted life years (DALYs)" among citizens.
To address the rising burden, the government aims to launch NIMHANS-2 — first announced by Finance Minister Nirmala Sitharaman during the Union Budget 2026-27 — to deliver specialized care for mental health and neurological disorders in north India.
"In addition, the Central Institute of Psychiatry, Ranchi, and the Lokopriya Gopinath Bordoloi Regional Institute of Mental Health, Tezpur, will be upgraded as regional apex institutions to strengthen mental healthcare services in the eastern and north-eastern regions," FM Sitharaman said.
