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.

Long COVID should be viewed as a web of overlapping symptoms rather than a single, uniform condition, according to a new systematic review published in eClinicalMedicine and reported by the Center for Infectious Disease Research and Policy (CIDRAP). The review highlights several recurring symptom patterns linked to long COVID, including neurological, respiratory, smell and taste-related, cardiopulmonary, and fatigue-driven clusters.

Researchers led by a team from Lanzhou University in Gansu, China, examined data from 64 studies conducted across 20 countries, covering nearly 2.4 million people. They grouped long COVID patients into subtypes using different approaches: symptom overlap in 30 studies, affected organ systems in 16 studies, symptom severity in nine, clinical markers in three, and other classification methods in the remaining research.

COVID Symptoms 2026: Fatigue Emerges As The Most Common Symptom

Among studies that focused on how symptoms appear together, fatigue stood out as the most consistently reported issue. It often occurred alone or alongside problems such as muscle and joint pain, brain fog, or breathlessness. Other symptom pairings that appeared frequently included loss of smell and taste, anxiety with depression, and various forms of musculoskeletal pain.

When researchers classified patients based on affected organ systems, respiratory problems were the most widespread, seen in about 47% of long COVID patients. Neurological symptoms followed at 31%, while gastrointestinal issues were reported by 28%. The authors stressed that these percentages reflect how often these clusters appeared within long COVID cases studied, not how common they are in the general population.

A smaller number of studies sorted patients by how severe their symptoms were, dividing them into mild, moderate, or severe categories using symptom scores, symptom counts, or quality-of-life measures. Three studies used clinical indicators for classification, including abnormal triglyceride levels and signs of restricted lung function on imaging.

COVID Symptoms 2026: Women Report Fatigue More Often

The review also found that long COVID subtypes vary based on demographic, socioeconomic, and medical factors. Women were more likely to report fatigue and neuropsychiatric symptoms, while men more commonly experienced respiratory issues. Older adults tended to show higher rates of respiratory, cardio-renal, and ear, nose, and throat symptoms.

Racial and ethnic differences also emerged. Black and Hispanic individuals were more likely to experience respiratory, cardiac, and neuropsychiatric symptoms, whereas White patients showed higher rates of fatigue and musculoskeletal complaints.

COVID-19 variants appeared to influence symptom patterns as well. The researchers noted that the Alpha variant was closely linked to smell-related and respiratory symptoms, while the Delta variant raised the risk of ENT-related problems. In addition, higher body mass index, socioeconomic disadvantage, and existing conditions such as chronic obstructive pulmonary disease were strongly associated with cardiopulmonary symptom clusters and a heavier overall long COVID burden.

Overall, the findings reinforce that long COVID rarely affects just one system in the body. Instead, it tends to involve multiple overlapping symptom groups, pointing to the need for more tailored, patient-specific care.

The authors call for future studies to focus on creating standardized ways to classify long COVID, identifying the biological mechanisms behind different symptom clusters, and testing targeted treatments for specific subtypes. They note that this approach will be essential for moving toward precision medicine and improving outcomes for people living with long COVID.

Singer and actor Ray J has reportedly been admitted to a hospital in Las Vegas after experiencing what were described as “heart pains,” according to TMZ. The 44-year-old was hospitalized on January 6, with sources telling the outlet that the episode was connected to a severe case of pneumonia. As of Thursday afternoon local time, Ray J was still receiving medical care, TMZ reported.

According to the report, doctors conducted multiple tests, including chest X-rays and an echocardiogram, an ultrasound that checks how well the heart is functioning. The findings from these tests have not been shared publicly. Neither Ray J nor his representatives have released an official statement addressing his health or confirming his current condition.

Although the initial concern focused on possible heart-related issues, TMZ noted that pneumonia appears to be the primary cause behind his hospitalization. It is still unclear whether Ray J remains admitted or has since been discharged.

Ray J Hospitalised With Pneumonia, Heart Pain

This is not the first time Ray J has dealt with a serious pneumonia-related health scare. In late 2021, he was hospitalized after doctors initially suspected COVID-19 before later confirming pneumonia.

At the time, Ray J described the ordeal as life-threatening. “I thought it was over,” he told TMZ while recovering. “I started praying and knew God is good, so I just kept praying.” He later made a full recovery and was discharged after receiving oxygen support.

Despite reports of his recent hospitalization, Ray J has remained active online. He recently posted on Instagram to promote an upcoming event in Austin, Texas, scheduled for January 18 as part of his birthday celebrations. The post made no reference to any health concerns.

Pneumonia: What Is This Disease?

Pneumonia is an infection of the lungs that causes inflammation in the air sacs, known as alveoli. These air sacs may fill with fluid or pus, making breathing difficult and reducing the amount of oxygen reaching the bloodstream. The illness can be caused by bacteria, viruses, or fungi and often presents with symptoms such as coughing, fever, chills, and shortness of breath.

While pneumonia is usually treatable with medication, it can become severe in certain cases, particularly among older adults, young children, and people with weakened immune systems. Because of these risks, pneumonia remains a leading cause of hospitalization, according to the Cleveland Clinic.

Does Pneumonia Come With Heart Symptoms?

Yes. Pneumonia can trigger heart-related symptoms and complications. According to Healthline, patients may experience a rapid heart rate, chest pain, or increased strain on the heart. In more serious cases, pneumonia can worsen existing heart conditions or lead to complications such as arrhythmias, heart failure, or even heart attacks.

The intense inflammation caused by a lung infection places added stress on the cardiovascular system, making early diagnosis and treatment especially important, particularly for older adults or those with underlying heart disease.

How Common Are Pneumonia And Heart Symptoms?

Pneumonia is a common illness and is frequently linked to heart complications. Research cited by the National Institutes of Health shows that roughly one in four hospitalized adults with pneumonia develop major cardiac issues, including heart attacks, heart failure, or abnormal heart rhythms. These complications significantly increase the risk of death.

Heart disease also raises the likelihood of developing pneumonia, creating a two-way relationship between the two conditions. Inflammation from the infection can put additional pressure on the heart, especially in older patients and those with pre-existing cardiovascular problems.

Is Pneumonia With Heart Symptoms Fatal?

Yes, pneumonia accompanied by heart-related symptoms can be fatal. Cardiac complications are common and greatly increase mortality risk, particularly among older adults and individuals with existing heart conditions such as heart failure. The danger is highest in the period immediately following the infection.

Pneumonia places heavy stress on the heart and can trigger heart attacks, strokes, or a rapid worsening of existing heart disease, underscoring the importance of prompt medical care.

• Increased Mortality: Heart complications can make pneumonia more severe and raise the risk of death.
• Triggers Cardiac Events: Infection-related inflammation can lead to heart attacks, strokes, or irregular heart rhythms, even in people without prior heart disease.
• Exacerbates Existing Conditions: For those with heart failure or cardiovascular disease, pneumonia can cause sudden deterioration, leading to respiratory failure and death.

Performing short and intense exercises that last for about 10 minutes may significantly reduce the risk of colorectal cancer, a British study shows.

Researchers at Newcastle University have found that completing brief workouts increases the concentration of several small molecules in the blood that have previously been linked to reducing inflammation, improving blood vessel function and metabolism.

The findings, which were published in the International Journal of Cancer, also noted that even short bouts of exercise can influence the activity of genes that govern tumor growth and fight against cancer.

Dr Sam Orange, Senior Lecturer in Clinical Exercise Physiology at Newcastle University and lead study author, said of the results, "What’s remarkable is that exercise doesn’t just benefit healthy tissues, it sends powerful signals through the bloodstream that can directly influence thousands of genes in cancer cells.

“It’s an exciting insight because it opens the door to find ways that mimic or augment the biological effects of exercise, potentially improving cancer treatment and, crucially, patient outcomes.

“In the future, these insights could lead to new therapies that imitate the beneficial effects of exercise on how cells repair damaged DNA and use fuel for energy.”

How Does It Work?

Researchers had asked each volunteer to complete a short, intense cycling test that lasted about 10 minutes and collected each of their blood samples which were then meticulously analyzed.

After studying about 249 proteins, the experts found nearly 13 protein had increased in their blood flow after the short exercise including interleukin-6 (IL-6), which helps repair the DNA of damaged cells.

When these exercise-induced proteins were applied to colorectal or bowel cancer cells by the scientists in a lab, they discovered that these new proteins could alter the activity of over 1,300 genes, particularly those who were responsible for DNA repair, energy production and cancer cell growth.

As a result, they concluded that performing even small exercises can activate a set of genes in the body's cells that can support efficient use of oxygen and promote energy metabolism. Additionally, the British researchers also discovered that the cell genes which have been previously associated with rapid cell growth were switched off after working out, suggesting that this might aid in controlling cancerous growths in the body.

What Is Colorectal Cancer?

Colorectal or bowel cancer is a common cancer that forms in the tissues of the colon (large intestine) or rectum, often starting as non-cancerous growths called polyps that turn cancerous over time.

Despite being treatable and preventable, colorectal cancer is currently the second leading cause of cancer-related deaths worldwide. Over 70,000 new cases of colorectal cancer occur annually in India, making it the fourth most common cancer in the country.

Typical symptoms usually include :

• Blood in or on the stool
• Changes in bowel habits (diarrhea, constipation, narrower stools)
• Abdominal discomfort, cramps, gas, or pain
• Feeling that your bowel doesn't empty completely
• Weakness, fatigue, or unexplained weight loss
