One of the commonest causes of illness, a sore throat often clears up on its own, but knowing what's causing it is important to treat it properly. Viral, bacterial, or caused by allergic elements - these kinds of sore throats have different characteristics that need different responses.

Sore throats have several origins, including infection and environmental factors. Some common causes include:

Viral infections: Viruses cause 90% of sore throat cases. Sore throats may result due to flu or common cold as well as those from chickenpox and measles that can all cause irritation.

Bacterial Infections: Streptococcus bacteria, the most common cause of strep throat, is the most common bacterial source. Strep throat is contagious and can lead to complications if untreated.

Allergies: Pollen, pet dander, and mold can trigger throat irritation, often accompanied by postnasal drip, sneezing, and watery eyes.

Environmental Factors: Dry air, pollution, and smoke can dry out or irritate the throat, creating a scratchy sensation.

Other Causes: GERD, vocal strain, even tumors may be responsible for chronic sore throats.

How to Distinguish Between Viral, Bacterial, and Allergic Sore Throats

Determining your cause of sore throat requires analysis of symptoms that accompany it, how long the sore throat lasts, and how bad the sore throat is.

Viral Sore Throats

The viruses that cause a sore throat are usually similar to a cold in their symptoms and tend to be milder than bacterial infections.

Symptoms of Viral Sore Throat

- Red, swollen throat without white patches

- Persistent cough

- Runny nose and nasal congestion

- Fever, usually mild

Duration: Viral infections last for 7–10 days without antibiotics.

Treatment: Home remedies, such as warm fluids, saltwater gargling, and over-the-counter pain relievers can help alleviate it.

Bacterial Sore Throats

Bacterial sore throats, mainly strep throat, are more severe and require prompt medical attention to prevent complications.

Symptoms of Bacterial Sore Throat

- Red and swollen tonsils with white patches or streaks of pus

- High fever

- Absence of a cough

- Nausea, vomiting, or stomach pain (especially in children)

- Small red spots on the roof of the mouth

Diagnosis: Rapid strep tests or throat cultures confirm the presence of bacteria.

Treatment: Antibiotics are necessary to eliminate the infection. Without treatment, complications like rheumatic fever or abscesses can develop.

Sore Throats Caused by Allergies

Throat irritation is caused by postnasal drip. Allergies create a buildup and drip of mucus down the back of the throat.

Allergic Sore Throat Symptoms

- Irritation of the throat and ears

- Runny eyes, sneezing, and nasal congestion

- These symptoms are usually relieved by antihistamines or removal from the source of the allergen

Duration: Allergic sore throats are sustained for as long as the allergens are exposed.

When to Seek Medical Care?

A sore throat should be taken to a doctor if:

- The condition lasts more than a week.

- There is shortness of breath or swallowing becomes painful.

- Swelling is too pronounced or the pain in the throat is extreme.

- High fever, rash, or joint pain occur along with the sore throat.

- A child shows signs of dehydration or refuses fluids due to throat pain.

Early diagnosis can prevent complications and speed recovery.

Effective Treatment for Sore Throats

Home Remedies for Viral and Allergy-Related Sore Throats

Viral infections and allergies often respond well to non-invasive treatments:

  • Drink warm teas, broths, or water to soothe the throat.
  • Gargling with warm, salty water can reduce inflammation.
  • These help soothe an irritated throat and can alleviate coughing.

Let your body rest sufficiently. Humidifying dry air will help keep the throat moist, especially when winter is on its way.

Why Not All Sore Throats Require Antibiotics?

Bacterial infections require antibiotics such as penicillin or amoxicillin. Finish the treatment completely to avoid reoccurrence or resistance.

How to Keep Sore Throats at Bay When Winter Is Near

Prevention is better than cure, and simple lifestyle changes can reduce your risk:

  • Wash your hands frequently to avoid infections.
  • Avoid close contact with sick individuals.
  • Use air purifiers to minimize exposure to irritants.
  • Stay hydrated and maintain a balanced diet to boost immunity.

Understanding the cause of your sore throat—whether viral, bacterial, or allergic—is key to effective treatment and recovery. While many sore throats resolve on their own, seeking timely medical advice for persistent or severe symptoms can prevent complications. Prioritize self-care, and don’t hesitate to consult a doctor when needed. Remember, your throat’s health is a vital part of your overall well-being.

A large new study suggests that about only two to four cups of coffee per day can reduce stress levels as well as lower the risks of developing anxiety and depression.

Researchers from Fudan University in China found that moderate coffee intake is linked to lower stress levels, while both very low and very high consumption don’t offer the same benefit.

Drinking more than four cups may start to increase stress and anxiety, likely because caffeine stimulates the nervous system and raises stress hormones.

Scientists believe this works like a “J-shaped curve”: a little caffeine can improve mood, alertness, and resilience to stress, but too much can overstimulate the body and make stress worse. Supporting research also shows that high caffeine intake is linked to higher perceived stress and anxiety symptoms.

At the top end of the scale, drinking five cups or more each day was associated with a higher risk of mood disorders – so it seems it is possible to overdo the buzz.

"J-shaped associations were identified between coffee consumption and mental disorders, suggesting that a moderate intake of coffee might be beneficial for mental health," write the researchers in their published paper.

Caffeine Can Recover Memory Loss From Lack of Sleep

In this animal study, scientists at the National University of Singapore have found that sleep-deprived mice struggle to recognize other mice however, mice that were given caffeine for a week before being being sleep-deprived performed much better on tests and did not show the same memory loss.

Additionally, when caffeine was directly applied to brain tissue from sleep-deprived mice, it improved communication between brain cells in this region -- suggesting that caffeine doesn’t just mask tiredness but may also help repair disrupted brain activity.

NUS physiologist Lik-Wei Wong explained: "Sleep deprivation does not just make you tired. It selectively disrupts important memory circuits.

"We found that caffeine can reverse these disruptions at both the molecular and behavioral levels. Its ability to do so suggests that caffeine's benefits may extend beyond simply helping us stay awake."

"Our findings position the CA2 region as a critical hub linking sleep and social memory. This research enhances our understanding towards the biological mechanisms underlying sleep-related cognitive decline. This could inform future approaches to preserving cognitive performance," NSU neuroscientist Sreedharan Sajikumar added.

Based on these results, the study concluded that sleep deprivation increases signaling linked to adenosine, a chemical that promotes sleep but can also weaken memory circuits. But with moderate amounts of intake, caffeine appears to block this effect and help the brain maintain normal function

While the discovery offers a clearer understanding of how sleep, memory and caffeine are connected, the findings are based on mice and more research is needed to confirm if the same benefits apply to humans.

How Much Coffee Should You Consume?

Due to how much caffeine can actually affect one’s body, experts recommend 400 milligrams only per day. That is about four cups, it is also better to consult a doctor about this as caffeine sensitivity is different for people. Some people are more sensitive to caffeine than others.

How you react depends on your health, what medicines you take, and how fast your body processes things. Too much caffeine can cause problems, so it's important to pay attention to how you feel and not go overboard. Here is what happens to your body when you drink too much caffeine daily.

Scientists Develop New Technique To Prevent AFib-Caused Strokes

Updated Mar 29, 2026 | 06:07 PM IST

SummaryAtrial fibrillation (AFib) is an irregular and often very rapid heart rhythm, also called an arrhythmia and can create blood clots in the heart, which can increase your risk of having a stroke by five times. Common symptoms include palpitations (the feeling that your heart is racing, chest pain, dizziness or feeling faint. However, a more severe symptom is a stroke

Atrial fibrillation (AFib) is an irregular and often very rapid heart rhythm, also called an arrhythmia and can create blood clots in the heart, which can increase your risk of having a stroke by five times.

When a person has AFib, the normal beating in the upper chambers of the heart (the two atria) is irregular and blood doesn't flow as well as it should from the atria to the lower chambers of the heart (the two ventricles).

Common symptoms include palpitations (the feeling that your heart is racing, pounding, fluttering or like you have missed heartbeats), chest pain, finding it harder to exercise, tiredness, shortness of breath, dizziness or feeling faint. However, a more severe symptom is a stroke.

Tucked inside the heart is a tiny pouch called the left atrial appendage. When the heart beats erratically, blood can pool and sit still in this pouch instead of flowing normally and still blood tends to clot. If one of those clots breaks free and travels to the brain, it can block blood flow and cause a stroke.

But researchers have now found new technique, in which a magnetically guided liquid is injected into the heart can harden and permanently seal the left atrial appendage from the inside. Early tests in rats and pigs suggest that this method could one day lower the risk of stroke in people with atrial fibrillation.

Based on this technique, researchers inject a magnetically responsive liquid, sometimes called a magnetofluid, directly into the left atrial appendage through a catheter.

Once inside the cavity, an external magnetic field helps guide and hold the fluid in place, so it fills the entire appendage, even against the force of circulating blood.

Within minutes, the liquid reacts with water in the blood and transforms into a soft "magnetogel" that seals off the cavity. Additionally, as the material begins as a liquid, it can adapt precisely to the highly irregular shape of each patient's left atrial appendage.

The death rate from AFib as the primary or a contributing cause of death has been rising for more than two decades.

Over 454,000 people with AFib are hospitalized in the US each year, out of which 158,000 die of the cause. It is estimated that 12.1 million people in the US will have AFib in the US will have AFib by 2050.

Who Is At Risk Of Having AFib?

Risk factors for AFib include:

  • Advancing age.
  • High blood pressure.
  • Obesity.
  • European ancestry.
  • Diabetes.
  • Heart failure.
  • Ischemic heart disease.
  • Hyperthyroidism.
  • Chronic kidney disease.
  • Moderate to heavy alcohol use.
  • Smoking.
  • Enlargement of the chambers on the left side of the heart.
In certain cases, AFib can be triggered by other things, such as alcohol, caffeine, smoking, recreational drugs, emotional stress and spicy food.

Treatment for AFib includes medications to control the heart's rhythm and rate, therapy to shock the heart back to a regular rhythm and procedures to block faulty heart signals.

A person with atrial fibrillation also may have a related heart rhythm disorder called atrial flutter. The treatments for AFib and atrial flutter are similar.

How To Improve Your Heart Health

Experts recommend following the below to reduce yor risk of stroke or developing AFib and maintaining heart health:

  • Don't smoke or use tobacco.
  • Aim for at least 150 minutes of moderate physical activity or 75 minutes of vigorous physical activity (or an equal combination of both) each week. Eat a heart-healthy diet.
  • Stay at a healthy weight.
  • Get quality sleep.
  • Manage stress levels
  • Get regular health screening tests.
  • Eat a fiber, nuts and fish-rich diet
  • Limit salt intake
  • Reduce saturated fat intake

Orforglipron, a new daily pill, may be more effective than existing oral treatments for weight loss and blood sugar control than semaglutide, according to a recent clinical trial.

Semaglutide belongs to a group of drugs known as GLP-1 medications, known to mimic a natural hormone that helps regulate appetite, slow digestion, and control blood sugar. The drug is commonly sold under the brand names Wegovy and Ozempic.

Despite being highly effective, semaglutide usually needs to be injected and requires refrigeration, which can make it inconvenient and harder to access for some patients. Additionally, the drug also carries a high price point.

However, in a 52-week trial involving people with Type 2 Diabetes, orforglipron was found to lower average blood sugar levels more than oral semaglutide and also led to greater weight loss.

Participants taking orforglipron lost around up to eight kilograms on average, compared to about five kilograms with semaglutide. Morever, orforglipron is a once-daily pill that does not require injections or cold storage.

But the study also found that orforglipron caused more side effects, particularly digestive issues like nausea and diarrhea. Yet scientists believe it may still be a better alternative to semaglutide as its easier and cheaper to produce than peptide-based drugs like semaglutide.

They also noticed that the drug absorbed more efficiently by the body and does not require strict timing around meals, unlike current oral versions of semaglutide.

How Does Ozempic Function?

The first thing to remember here is that Ozempic is a brand-name medicine that contains semaglutide as its active ingredient. Semglutide is the synthetic version of GLP-1—a natural hormone produced in the intestines that regulates blood sugar, appetite, and digestion. Now, every time you eat, your body produces various hormones, including GLP-1. These are called Post nutrition hormones, and help you absorb the energy you just consumed.

GLP-1 travels to your pancreas, prompting it to produce insulin. It also travels to the hypothalamus in your brain, which gives you the feeling of being full or satiated. Ozempic imitates this hormone, thereby, silencing the food chatter in the brain. Interestingly, for some people this food chatter is really quiet ( people with low appetite) and for others it is an outbrurst, (people who generally binge eat.) So with Ozempic, silencing this self-talk in the brain, people tend to lose their appetite and eventually weight.

However, it is important to note that losing weight includes not just fat but muscle as well. Losing too much muscle can lead to reduced strength and a shorter life span. Notably, records show that most people who start taking them stop it at 12 weeks; therefore, it is important for some but not for others.

Does Ozempic Have Side Effects?

As reiterated by doctors and health care experts, Ozempic is a drug that is tasked to help diabetic patients manage their blood sugar levels and weight. However, recent research has shown its effectiveness in mitigating various addictions like alcohol and drugs by inhibiting hormones. But what people ignore are its side effects, which include:

  • Nausea is a frequent side effect, especially when starting Ozempic or increasing the dose, and vomiting may occur along with nausea.
  • Diarrhoea and abdominal discomfort also show up in people using Ozempic, but they generally resolve as your body adjusts.
  • Ozempic can reduce appetite but may also lead to unintended weight loss or reduced food intake, causing discomfort for some people.
  • There are certain less common, but serious side effects also, like Pancreatitis, or inflammation of the pancreas.
  • This drug may also cause severe kidney issues, particularly if dehydration occurs from side effects like vomiting or diarrhoea.
