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 simple five-factor risk score may help identify people at high risk of dementia, particularly in low- and middle-income countries (LMICs), where around 60% of the world's dementia cases now occur.

Developed and validated by researchers at Northumbria University, the risk score uses five everyday factors to identify older adults at higher risk of dementia. It aims to address a gap in dementia research, as existing prediction tools have largely been developed using data from high-income countries and may not work as well in lower-income settings.

The research team developed the model using data from more than 11,000 older adults across seven countries and three continents.

“We know the burden of dementia is shifting towards lower-income parts of the world, yet the prediction models clinicians and researchers rely on were designed with wealthier populations in mind. This model is a step towards changing that. It is simple, it is built for the settings where it is needed most, and it gives researchers a practical way to find the people who should be the focus of future studies and trials,” said Dr Eduwin Pakpahan, from Northumbria University's Applied Statistics and Data Science Research Group. The study is published in the American Journal of Epidemiology.

What Are The Five Factors Used To Predict Dementia Risk?

The model can be applied using information gathered through a straightforward conversation with an older adult and, where relevant, a family member or carer. It does not require blood tests, brain scans or specialist equipment.

The five factors included in the risk score are:

• Age: The strongest single predictor. Dementia risk rises meaningfully from age 70 and more steeply from 80 onwards.
• Social engagement: This includes whether a person is married or living with others, how often they meet friends or family, and whether they participate in community or religious groups.
• Physical activity: The model considers how active a person is in daily life, across both work and leisure. Everyday movement, such as farming, walking to the market or doing household tasks, also counts.
• High blood pressure: Uncontrolled hypertension can damage the blood vessels supplying the brain over time. It is common, often undiagnosed in lower-income settings, and inexpensive to manage.
• Difficulty managing money: A family member or carer is asked whether the person has experienced a noticeable change in their ability to handle finances. This can be one of the early everyday signs of cognitive change.

How Does The Dementia Risk Score Work?

Each factor contributes points towards a total score ranging from 0 to 9. A person scoring 0 has around a 1% chance of developing dementia within three years, while someone scoring 9 has a nearly 19% chance.

The researchers built and tested the model across seven sites in China, Cuba, the Dominican Republic, Puerto Rico, Venezuela, Mexico and Peru. It achieved a performance score of 0.75, above the 0.70 threshold generally regarded as clinically useful.

However, the researchers emphasise that the tool is primarily intended for research rather than routine screening of the general population. It could give researchers and clinical trial teams a practical, low-cost way to identify and recruit people at higher risk of dementia.

The team has also called for the model to be validated in regions not covered by the study, particularly South Asia, the Middle East and North Africa, and Sub-Saharan Africa.

Why Is A Dementia Risk Prediction Tool Important?

Dementia affects more than 57 million people worldwide, with around 60% of cases occurring in LMICs across Latin America, the Caribbean, Asia and Africa.

Identifying people at higher risk could help researchers in these regions plan studies and clinical trials that better reflect their populations. A simple tool based on everyday information may also make risk assessment more accessible in settings where specialised diagnostic resources are limited.

From Independence Day and Janmashtami to Ganesh Chaturthi, Onam, Eid, Navratri, Dussehra, Diwali, Christmas and New Year, the period from August to January means celebrations across the country. However, some can also suffer from stress, loneliness and worsening of pre-existing mental health symptoms.

In India, festivals can provide connection, cultural continuity and family bonding. However, celebration is not positive for everyone. For some, the period can lead to issues such as social pressure, loneliness, grief, financial concerns and even interpersonal conflict. Festive periods can be challenging for the general population, while people with pre-existing mental health conditions may be vulnerable to worsening symptoms, increased sensitivities or relapse.

Festivals carry an expectation that everyone should be happy. People are expected to participate, dress up, attend gatherings and appear enthusiastic. Though some may experience anxiety, burnout, depression or emotional exhaustion, maintaining this expected level of participation can become another source of stress. Emotional wellbeing does not automatically change because it is a festival. Recognising this can reduce guilt and self-criticism.

Family Gatherings And Emotional Sensitivities

Festivals frequently bring extended families together. While this can strengthen relationships, it can also reactivate longstanding interpersonal dynamics. Questions about marriage, children, career, finances, appearance or personal choices can become uncomfortable, particularly when they touch existing vulnerabilities.

For someone who has experienced criticism or comparison within the family, a seemingly casual festive comment may carry considerably more emotional weight because of the history attached to it. The festive setting can therefore bring individuals into closer contact with relationships or unresolved issues that they may otherwise have greater distance from.

Why Clinical Populations May Be More Vulnerable

For individuals already living with a mental health condition, the festive season can introduce several stressors simultaneously. Travel, disrupted sleep, irregular meals, increased social stimulation, financial pressure, family conflict and interruptions to established treatment routines can place additional demands on psychological functioning.

People with conditions such as depression, anxiety disorders, bipolar disorder, trauma-related conditions, obsessive-compulsive symptoms, eating disorders or other psychiatric difficulties may be more sensitive to these changes.

In individuals with a history of recurrent episodes, significant disruption may also contribute to relapse. Festivals themselves do not necessarily cause relapse. Rather, the accumulation of environmental, interpersonal and behavioural stressors can increase vulnerability in someone already at risk.

Changes from an individual's usual baseline such as significant alterations in sleep, appetite, mood, anxiety, irritability, impulsivity, social withdrawal or functioning can therefore be important early warning signs.

Grief Can Become More Visible

Many traditions are built around shared experiences: preparing food, decorating homes, travelling to family members, exchanging gifts or gathering for meals. When someone important is no longer present, familiar rituals can make their absence more noticeable.

This can occur during religious festivals as well as occasions such as Independence Day or New Year, when people naturally reflect on their lives and relationships. Participating in a celebration does not mean grief has disappeared, just as sadness during a celebration does not eliminate the capacity for joy.

The festive season can also place pressure on household finances. Clothing, gifts, travel, home decoration and social events can increase expenditure over several months. For those already experiencing financial uncertainty, this can create considerable stress.

People living alone, those estranged from family, individuals experiencing relationship difficulties, older adults and people who have recently relocated may become more conscious of social isolation during this period. New Year can be particularly challenging because social expectations around parties, relationships and celebration become highly visible.

Indians Living Abroad: Culture, Belonging and Homesickness

Celebrating Diwali, Eid, Navratri, Onam, Christmas or Gurpurab away from India can provide an important connection with cultural identity and family traditions. At the same time, it can highlight physical distance from parents, siblings and extended family.

A person may attend a community celebration abroad while still missing the food, sounds, neighbourhood atmosphere and family rituals associated with celebrations in India. Those unable to travel home may experience increased homesickness, particularly when several major occasions occur within a short period.

Festivals Can Be Difficult For General Population Too

Feeling tired, overwhelmed, irritated, lonely or emotionally sensitive during a demanding period does not automatically indicate a psychiatric disorder.

Even psychologically healthy individuals can experience festive stress because of travel, social obligations, financial commitments or difficult family interactions.

Making The Festive Season Psychologically Sustainable

• Set boundaries around intrusive questions: “I’d rather not discuss that today” or “We’re comfortable with where things are right now” can end conversations about marriage, children or finances without confrontation.
• Decline invitations without over-explaining.
• A smaller number of meaningful gatherings may be preferable to trying to attend every event.
• Decide spending limits for gifts, travel and celebrations in advance rather than responding to social pressure.

For those receiving mental health care, prescribed medication, therapy and established support systems should not be casually disrupted during the festive period.

Curated festive content represents selected moments, not the entirety of another person's life.

Professional support becomes particularly important when festive stress is accompanied by persistent hopelessness, severe anxiety, substantial social withdrawal, changes in sleep or appetite, increased substance use, impaired functioning or other marked behavioural changes.

The goal is not to remove complexity from celebration, but to make space for it. Allowing people to experience the festive season without the pressure to feel festive can itself be an important form of psychological care.

As Delhi wakes up to another spell of deteriorating air quality just days ahead of Diwali, ophthalmologists warn that dust, smoke, particulate matter, and toxic gases can affect children's eyes, triggering redness, itching, burning, excessive watering, and dryness.

On Tuesday, India's national capital's average Air Quality Index (AQI) climbed to 331 at 7 am, entering the ‘very poor’ category. At the same time, eight monitoring stations recorded readings above 400, falling in the ‘severe’ zone, according to the Central Pollution Control Board (CPCB).

As per data from the CPCB, 33 of the city's 58 monitoring stations recorded AQI levels in the ‘very poor’ category. Meanwhile, the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology have forecast that air quality is likely to remain in the ‘very poor’ category over the coming days.

“Children’s eyes are more sensitive to irritants in the environment, and exposure to pollutants, particulate matter and toxic gases can irritate the surface of the eye,” Dr Shibal Bhartiya, Clinical Director – Ophthalmology and Program Director – Community Outreach and Wellness at Marengo Asia International Institute of Neuro and Spine (MAIINS), told HealthandMe.

How Does Air Pollution Affect Children's Eyes?

The experts warned that exposure to pollutants and particulate matter can irritate the surface of children's eyes, causing redness, itching, burning, excessive tearing and dryness.

Dr Neepa Thacker Dave, Senior Consultant in Paediatric Ophthalmology at SRCC Children's Hospital, told HealthandMe that the eye’s surface is protected by a delicate tear film that provides lubrication, maintains clear vision and helps defend against environmental irritants. Exposure to airborne pollutants can disturb this protective layer and contribute to ocular surface irritation and inflammation.

"Excessive watering does not necessarily mean that the eyes are adequately lubricated. Irritation can trigger reflex tearing even when the tear film is unstable. Consequently, children may experience watering alongside dryness or discomfort," she said.

Further, children with existing allergies or sensitive eyes may notice their symptoms worsening during periods of high pollution.

“Long-term exposure to poor air quality may also worsen pre-existing ocular surface conditions,” Dr Bhartiya said.

Reducing children's exposure to pollution is important, particularly on days when air quality is poor.

Dr Bhartiya advised parents to:

• Avoid outdoor activities when pollution levels are high.
• Keep windows closed during periods of severe pollution.
• Encourage children to avoid rubbing their eyes.
• Ensure children wash their faces after coming indoors.

Dr Dave also highlighted the importance of greater awareness, reduced exposure and timely medical care in protecting children from pollution-related eye irritation and discomfort.

When Should Children See an Eye Specialist?

Dr Dave said children may not always have the vocabulary to describe eye discomfort. Parents and teachers should watch for frequent eye rubbing, excessive blinking, squinting, watering or reluctance to participate in reading and outdoor activities.

Parents should not dismiss eye irritation in children, particularly when pollution levels are high.

Although mild irritation may improve when exposure is reduced, recurring or persistent symptoms warrant an eye examination. Eye pain, significant sensitivity to light, blurred or reduced vision, marked redness or difficulty opening the eye require prompt medical attention.
