Are you down with fever? Are your symptoms also a little less common from an ordinary cold? Are you also confused between flu and COVID? Then knowing this one symptom could help you set flu apart from COVID. Dr Rupa Parmar, a GP and medical director at Midland Health tells The Mirror, that shortness of breath could be a key symptom that could differentiate between the two.

Dr Parmar highlights that it is a key indicator for COVID. "Shortness of breath is rare in both a cold and the flu, but as COVID more so affects the lungs due to inflammation, it is a common symptom."

The NHS website supports her advice, noting that breathlessness is a symptom more often tied to Covid, not the flu or a common cold. This kind of breathing difficulty is usually associated with infections like Covid or respiratory syncytial virus (RSV).

What Else Could Help You Know If You Have A COVID or Flu?

The nature of your cough could also help you understand different ailments. Dr Parmar said that a cold would produce a mild cough, whereas a flu cough could be more dry. However, with covid, "a cough will be dry and continuous, and many people will cough for more than an hour or have three or more coughing episodes within a day."

If one has lost their sense of smell or taste, then the chances are, this could be COVID. However, this symptom is also present in cold or in a flu.

For people who have Covid, the NHS advises staying home and avoiding contact with others if they or their children have symptoms and either develop a high temperature or feel too unwell to work, attend school, manage childcare, or carry out daily activities. If you are unsure about the cause, it is important to speak with a doctor.

Dr Parmar emphasized: "after all, it is always better to be safe than sorry when it comes to health."

What Is Flu?

The flu is a common respiratory illness that happen from the influenza virus. The common flu symptoms are:

  • Fever
  • Sore Throat
  • Runny Nose
  • Fatigue
  • Body Aches
  • Cough
  • Headaches

What Is COVID-19?

As per the US Centers for Disease Control and Prevention (CDC), COVID-19 is a respiratory illness caused by the coronavirus. The common symptoms include:

  • Fever
  • Cough
  • Fatigue
  • Headache
  • Nausea
  • Sore Throat
  • Runny Nose
  • Loss of smell or taste

COVID-19 could also have some long-lasting symptoms unlike flu or cold, that could seem unrelated to the original infection.

As per the Ohio State University, the most recent COVID variant is XFG or the Stratus variant. Another new variant that causes the 'razor blade' like sore throat is Nimbus.

The symptoms of this new variant includes:

  • Congestion
  • Cough
  • Fever
  • Headache
  • Sore throat
  • Muscle Aches

'Razor blade' Throat

NB.1.8.1 or the Nimbus variant is a subvariant of Omicron, which is a dominant COVID variant since late 2021. Omicron variants tend to cause more throat problems than the other variants seen earlier.

The COVID virus binds to ACE2 receptors. According to WebMD, the cells in your nose and throat contain more ACE2 receptors than those deeper in the lungs, which makes them easier targets for Omicron variants. Once the virus attaches to these receptors in the upper airway, your immune system begins to respond.

Dementia Is Directly Linked To Obesity And High Blood Pressure: Study

Updated Jan 26, 2026 | 07:36 PM IST

SummaryYour weight can affect multiple aspects of your health, whether it is the functioning of a crucial organ such as the heart or your mental capacity. A new study revealed that obesity is directly linked with not just high blood pressure, but also dementia. Here is what you need to know

Your weight not only affects your heart health but also your brain health. A recent study published in the Journal of Clinical Endocrinology & Metabolism has revealed a powerful connection between your body weight, heart and brain.

After studying over 500,000 people, scientists discovered that having a high Body Mass Index (BMI) can nearly double your chances of developing brain-related illnesses later in life, which confirms that being overweight and having high blood pressure are not just general health concerns, they are direct causes of dementia.

How Does Your Weight Affect Brain Health?

The study focused heavily on vascular dementia, a specific type of memory loss that occurs when the brain is damaged because of a lack of blood flow.

Think of your blood vessels like a system of pipes. If those pipes are narrowed or blocked due to weight-related issues, the "engine" (your brain) doesn't get the fuel it needs. Over time, this lack of oxygen and nutrients leads to permanent brain damage and the loss of memory and thinking skills.

Researchers found that high blood pressure, often caused by carrying extra weight, is the main "middleman" in this process. Blood pressure is measured with two numbers, and both play a part in brain health:

Systolic

This is the pressure when your heart beats. It accounts for about 18 percent of the link between obesity and dementia.

Diastolic

This is the pressure when your heart rests between beats. It accounts for about 25 percent of the link. When these numbers stay high, they constantly "batter" the delicate vessels in the brain, causing them to weaken or clog.

How Weight Affects the Brain

Beyond just blood flow, a high BMI impacts the brain in several other ways:

Increased Inflammation

Obesity often causes the body to be in a constant state of "alarm" or inflammation. This can irritate the immune system and eventually damage brain cells.

Metabolism Issues

When the body struggles to process energy and food properly, it changes how the brain uses energy, which can lead to cognitive decline.

Heart Strain

A heart that has to work harder to pump blood through a larger body eventually becomes less efficient at sending blood all the way up to the brain. Your heart essentially has to do twice as much work as it would at a lower weight.

Can Preventing Obesity Help Dementia?

The most encouraging takeaway from this study is that dementia isn't always a matter of bad luck or "old age." Researchers call this an unexploited opportunity.

By managing your weight and blood pressure early in life, through a healthy diet, consistent exercise, and good sleep, you are essentially "dementia-proofing" your brain. The researchers suggested that intervening early, possibly even with weight-loss medications before symptoms start, could be a key strategy for protecting brain health in the future.

How Much Does Obesity Affect Worldwide?

According to the World Health Organization, one in eight people in the world are living with obesity. In 2022, about 2.5 billion adults were overweight. Causes of it vary, from things like diseases or chronic conditions, to the kind of food that is available to consume.

You Can Stop A Heart Attack With This Medicine, Cardiologist Reveals Heart Attack 101

Updated Jan 26, 2026 | 07:35 PM IST

SummaryHeart attacks are much more common than we realize. One person dies every 34 seconds from a cardiovascular disease and is one of the leading causes of deaths for men and women. However, do you know how to deal with one if it happened to you or someone near you?

Heart attacks need immediate intervention and Dr. Balbir revealed one medicine that can save a life when this happens: Aspirin. In an interview with HealthandMe, Dr. Singh revealed that one does not need fancy equipment to help a person having a heart attack.

“If the history of the family history or cholesterol or diabetic. This patient is at risk, so what is the medicine if you get such a symptom? Aspirin.”

What Medicine Can Help a Heart Attack?

Dr. Singh points out that if you or someone near you begins to experience symptoms of a heart attack, such as heavy chest pain, pressure, or unexplained sweating, taking a dissolvable aspirin immediately can be a lifesaver.

By dissolving a tablet (like Dispirin) in a glass of water and drinking it, the medicine dissolves into the bloodstream much more quickly than simply ingesting it.

Aspirin works by thinning the blood and preventing further clotting in the arteries, which can stop a heart attack from getting worse before medical professionals arrive.

Other Preventative Measures To Take For Heart Attack

Before medical professionals arrive, performing CPR can also help save a person's life; however, one must know the right way to do CPR.

While speaking to HealthandMe, Dr Singh mentioned a viral video where a person collapses and someone attempts to give them CPR while they are still sitting in a chair, notng that this was 'a dangerous mistake' and people should steer clear away from such false videos.

He explained that you cannot perform CPR on someone who is sitting up as the body must be positioned correctly for the heart and lungs to receive the benefit of the chest compressions.

Without the proper technique, blood will not reach the brain and your efforts will not help the patient. Understanding the proper sequence of events is the difference between a failed attempt and a saved life.

Step 1: The Importance of Positioning

If someone collapses, immediately place them flat on their back on a hard floor. You need the ground's resistance to pump the heart manually. In this position, the heart is "sandwiched" between the rib cage and spine. On a soft bed, your presses will fail to squeeze the heart effectively.

Step 2: Focus on the Heart First

Dr. Singh emphasizes that restarting the heart is the absolute priority. Place both hands in the center of the chest and use your body weight to press firmly. By pushing the rib cage toward the spine, you force the heart to pump. Often, once circulation starts, the patient begins breathing again spontaneously.

Step 3: The Proper CPR Sequence

If the person doesn't wake up, begin a rhythm of three chest presses followed by one mouth-to-mouth breath. Lock your elbows and press hard to ensure the heart is being squeezed between the bones. This specific cycle keeps oxygenated blood moving to the brain, preventing permanent damage during a cardiac emergency.

How Common Are Heart Attacks?

According to the Centers for Disease Control and Prevention, heart attacks claim a life every 34 seconds. In 2023, it caused nearly 920,000 deaths, one in every three recorded. Hence it is important to know not just the ways to help when someone has a heart attack but also how to prevent them.
