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.

Warning Sings of A Heart Attack

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.

When to Seek Medical Attention

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:

• Symptoms induced by exertion and relieved by rest
• The simultaneous onset of several warning signs, including weakness, dizziness, and nausea
• Personal or family history of heart disease, hypertension, diabetes, or smoking

Preventing Heart Attacks: Proactive Steps for Heart Health

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.

34 children have been infected in North London due to a measles outbreak. Health officials have confirmed the outbreak from Enfield in laboratory tests. Doctors too have pointed that children were not fully immunized. Measles was earlier eliminated in the UK, however, the disease is making a come back with UK losing its elimination status. The World Health Organization (WHO) also announced the elimination status of UK based on 3,600 suspected cases in 2024.

Unique Symptoms Of Measles

With the disease now making a comeback, the worry is real. Measles has a high transmissibility, and high measles immunity levels are required to prevent sustained measles virus transmission.

This is why herd immunity for measles could be easily breached.

It easily spreads from one infected person to another through breathes, coughs or sneezes and could cause severe disease, complications, and even death.

Symptoms include:

• High fever
• Cough
• Runny Nose
• Rash all over the body

The most unique symptom or the early sign of measles in the Koplik spots. These are tiny white dots that look like grains of salt on red gums inside the cheeks that appear before the red rash starts to appear on a person's face and then the body.

Furthermore, the symptoms of measles are also characterized by the three Cs:

• Cough
• Coryza or runny nose
• Conjunctivitis or red and water eyes

How Long Does The Infection Last?

The progression of the symptom comes in two stages, first is the prodromal stage or Days 1 to 4, where one would notice high fever, cough, runny nose, red and watery eyes, sore throat, fatigue, and Koplik spots.

The second stage is called the rash stage or the days 5 to 10 or even more where rash start to appear on the hairline, and then it runs down the body. It lasts for several days and fades in the same order.

The first symptoms, notes the Centers for Disease Control and Prevention (CDC), appear 7 to 14 days after a measles infection. Often, it could also lead to ear infection, or even diarrhea. Though these complications happen in every 1 in 10 children or individual with measles.

Who Is At Risk Of Measles?

• Children who are younger than 5 years of age: nearly 1 to 3 of every 1,000 children who become infected with measles will die from respiratory and neurologic complication, notes the CDC
• Adults older than 20 years of age
• Pregnant Women
• People with weakened immune system, such as from leukemia or HIV infection

Why Has Measles Return To The UK?

In late 2023, measles outbreaks were reported in the UK, which led to a surge in cases in 2024. Vaccination uptake at the end of 2024 was 92% for the first dose, however, for the second dose, it was below 82%.

Dr Vanessa Saliba, consultant epidemiologist at UKHSA said, "Infections can return quickly when childhood vaccine uptake falls - measles elimination is only possible if all eligible children receive two MMRV doses before school. The NHS is making vaccination easier, including offering the second MMRV dose earlier at a new 18-month appointment to boost uptake and support elimination goals."

She also noted that children and adults must get vaccinated as NHS also offers catch-up jabs.

Dr Baharat Pankhania, from the University of Exeter, as reported by the BBC said, "Measles is an infection that can be prevented by vaccine - and it's extremely concerning that in the UK we now have pockets of low or no vaccine uptake. We urgently need to remedy this situation." Pankhania also noted that there is a need to make the access to GPs easier, and for an effort that could immunize babies in their homes and counter wrong information around vaccine safety.

Often, we underestimate the way our brain works and daydreaming has long been seen as a major sign of creativity. Many artists have used their imagination to bring their work to life. However, science offers a different perspective.

Coined in 2002 Dr. Eliezer Somer, those who experience “maladaptive daydreaming” often fantasize about celebrities, historical figures or idealized versions of themselves. Their imaginations are more elaborate, diverse, and complex as compared to other daydreamers.

A 2012 Consciousness and Cognition study found that maladaptive daydreamers spend, on average, 57 percent of their waking hours daydreaming far more than their counterparts.

Dr Somer explains: "The greatest difference is the maladaptive daydreamers reported that the activity interfered with their daily life. They also reported higher rates of attention-deficit and obsessive compulsive symptoms, and more than 80% used kinesthetic activity or movement when daydreaming, such as rocking, pacing or spinning"

He further noted that while everyone experiences moments of mind-wandering, it usually does not interfere with daily life. But maladaptive daydreaming does interfere in regular life. The condition has not been classified as a mental illness and there is no treatment for it yet.

What Do People Say?

Many Reddit users have shared their experiences with maladaptive daydreaming, often asking questions such as: “Is it normal to daydream for such long hours?”

While some responses described daydreaming as a form of dissociation when bored, others relied on music or movies to fuel fantasies of being a “better version” of themselves, often struggling to return to reality.

Common Symptoms Of Maladaptive Daydreaming

Here are some early signs of maladaptive daydreaming to keep an eye out for:

• Compulsive need to daydream
• Avoiding social interaction and activities
• An inability to perform work or other daily tasks
• Extreme feelings of shame or guilt
• Feeling a compulsive need to daydream that you can't control
• Making a conscious effort to stop or lessen daydreaming episodes.
• Intense and extremely vivid daydreams
• Complex and elaborate daydreams, often with many people involved
• Daydreams accompanied by repetitive movements such as pacing
• Prolonged daydreams that may last hours at a time
• A feeling of disconnect or dissociation from people and reality during the episode.

What Does Science Say?

Rachel Bennett, a member of Dr. Somer’s online community, shared she usually dreams up new episodes of her favorite Japanese animé characters and TV shows. She’s also created four families of fictional characters which have grown with her over the years.

“I’d much rather stay home and daydream than go out,” she said.

What Causes Maladaptive Daydreaming?

Dr. Somer noted that about one-quarter of maladaptive daydreamers are trauma survivors who use daydreaming as an escape. Many report family members with similar tendencies, as well as being shy or socially isolated.

Meanwhile, a Harvard Medical study found that 80 percent of maladaptive daydreamers have ADHD, followed by anxiety disorders, depression, and OCD. Researchers believe daydreaming often acts as a coping mechanism for pent-up emotions that cannot be expressed in real life, so they are released through imagination instead.

How Do You Cope With Maladaptive Daydreaming?

Experts emphasize that maladaptive daydreaming is not an extreme condition requiring formal diagnosis, but many people have shared strategies that help:

• Exercise: One forum user reported swimming daily, gradually reaching 2,000 meters, which acted as meditation and grounded them in reality.
• Remove triggers: Avoid activities that spark daydreaming episodes.
• Practice mindfulness: Stay present and aware of thoughts.
• Limit music use: Music is a common trigger.
• Scheduled daydreaming: Set aside specific times with a timer, then consciously exit the session.
• Seek professional help: Therapies such as CBT, DBT, and mindfulness-based stress reduction have shown benefits.
• Stay busy: Engage in tasks to prevent wandering thoughts.
• Improve sleep quality.
• Make daydreams less appealing: Reduce instant gratification.
• Self-development and creativity: Channel imagination into productive outlets.
• Journaling: Record thoughts daily or weekly.
• Practice self-acceptance.
• Find group support.

In January 2026, a Guardian investigation uncovered something deeply unsettling. Google’s AI summaries, designed to quickly answer search queries, were giving users inaccurate health information. Some of the advice was not just misleading but potentially dangerous.

One striking example involved liver function tests. The AI presented incorrect “normal ranges,” which could make someone with a serious liver infection believe their reports were fine. Following the investigation, Google quietly removed AI Overviews for certain queries such as “normal range for liver function tests” and similar searches.

Soon after, another finding raised further alarm. Researchers discovered that Google’s AI Overviews frequently relied on YouTube rather than established medical websites when responding to health questions. Considering nearly two billion people use Google search every month, the implications were hard to ignore.

Is AI Replacing Medical Advice

For years, doctors have warned about “Dr Google” and self diagnosis. But the situation has now moved beyond search results. People are increasingly asking AI tools directly for answers to complex medical problems.

The search optimization platform SE Ranking analyzed more than 50,000 health searches in Germany. The most cited source in AI responses was YouTube, which accounted for 4.43 percent of citations. That is about 3.5 times more than netdoktor.de, one of the country’s biggest consumer health portals. It was also cited more than twice as often as the well known medical reference MSD Manuals.

Only 34.45 percent of citations in AI Overviews came from reliable medical sources. Government health institutions and academic journals together contributed roughly one percent. No hospital network, university, or medical association came close to YouTube’s citation numbers.

Why Experts Are Concerned

The concern is simple. YouTube is a video platform, not a medical publisher. While qualified doctors upload educational videos, the platform also hosts wellness influencers, life coaches, and creators without medical training.

In one particularly worrying example, Google’s AI advised pancreatic cancer patients to avoid high fat foods. Medical experts say this recommendation is the opposite of what many patients actually need and could increase mortality risk.

AI Overviews also gave incorrect information about women’s cancer screening tests. Experts warned this could lead people to dismiss serious symptoms and delay diagnosis.

The Rise of Chatbot Medicine

The shift is not limited to search engines. Chatbots are rapidly becoming everyday health advisers. OpenAI estimates about 40 million people globally use ChatGPT for healthcare guidance each day.

A 2026 Health and Media Tracking Survey by the Canadian Medical Association found roughly half of Canadians consult Google AI summaries or ChatGPT for medical concerns.

The outcome has not been reassuring. People who followed AI advice for self diagnosis and treatment were five times more likely to experience negative health effects than those who did not.

Studies help explain why. A 2025 University of Waterloo study found GPT 4 answered open ended medical questions incorrectly about two thirds of the time. Another 2025 Harvard study showed chatbots often agreed with flawed assumptions instead of correcting users, such as confusion between acetaminophen and Tylenol.

Researchers say AI systems tend to be overly agreeable and confident, prioritizing helpful responses rather than critical reasoning.

Confidence Versus Care

Despite knowing AI can be wrong, many people still rely on it. Long waits for specialists, lack of family doctors, and limited access to healthcare make instant answers appealing.

The real concern is not curiosity but unquestioned trust. Looking up symptoms is one thing. Acting on AI advice without verification is another.

The technology is powerful and useful, but when confident sounding answers replace medical judgement, the consequences can affect real lives.
