This digital era is all about catching up with trends, TikToks and reels, but at the cost of what? Many believe all of this happens at the cost of one's health and mental well-being. As a result, the grades of students, especially in high school, when they are exposed to social media the most, start to drop. However, a study based on the University of Birmingham's findings, peer-revied and published by the Lancet's journal for European health policy compared 1,277 students and the rules their 30 different secondary schools had for smartphone use at break and lunchtimes.` The study found something else, contrary to the popular belief.

What Did The Study Find?

The study found that banning phones in school is not linked to pupils getting higher grades or having a better mental wellbeing. The study found that a student's sleep, classroom behavior, exercise or how long they spend on their phones did not seem much different for schools with phone bans versus schools without it.

However, the study did find that spending longer time in social media or on smartphones in general may be linked to such measures. This was the first study in the world that looked at school phone rules along with the children's health and education.

In an interview to the BBC, Dr Victoria Goodyear, study's lead author said, that the findings are not against smartphone bans in school, but, a suggestion that bans in isolation are not enough to tackle the negative impacts.

The focus must be on reducing how much time the student spends on their phone, which cannot just be supervised in school.

How Was The Study Conducted?

The schools were chosen from a sample of 1,341 mainstream state schools in England. Among these the behavior of student form schools that banned the smartphones versus those who did not ban it were studied to find out that schools restricting smartphone use did not seem to see the intended improvements on health, wellbeing and focus of the student, as one would have wished to.

The study also used the internationally recognized Warwick-Edinburg Mental Well-Being Scale, a measure of mental well-being focusing entirely on positive aspects. It is a 14-item scale with 5 response categories. This method was used to determine the wellbeing of the children who participated in the research. It further looked at students' anxiety and depression levels.

It also asked from teachers about whether their students were on target, below target or above target in English and maths.

What Do The Students Feel?

When asked students, they said that the smartphone ban forces you to hang out and chat with your friends and some of them think in lower school, it has helped them spend less time scrolling social media and making lots of friends.

Experts point out that the important part is to help students learn to use their phone in a safe and controlled space. This way, phone-related issues, especially distraction, its impact on your mental health, will be much less. The answer is not ban, but the use of the smartphone in a controlled environment, so students learn to value the "freedom" they have been given to use them at break and lunch.

The fine particulate in air pollution could do more damage than brain inflammation. New research indicates long-term exposure to air pollution could lead to changes in the brain structure, rapid biological ageing and a higher risk of dementia.

A study from the UK Biobank, which tracks the health of hundreds of thousands of people in Britain, found that those exposed to the highest levels of fine particulate matter (PM2.5) had a 14% higher risk of developing dementia than those with the lowest exposure.

Researchers examined more than 400,000 participants for nearly 14 years, during which almost 9,000 dementia cases were recorded.

The findings, published in the Journal of Nutrition, Health & Aging in April 2026, also identified that greater pollution exposure could be linked to reduced brain volumes.

PM2.5 consists of particles small enough to penetrate deep into the lungs. Some components can enter the bloodstream, while other particles may reach the brain through ways that are still being investigated.

One possibility is that pollution triggers inflammation throughout the body, which can affect blood vessels and brain tissue. Researchers are also examining whether particles that we inhale can reach the brain directly and influence the proteins, cells and processes that lead to neurodegenerative diseases.

Caleb Finch, professor emeritus at the University of Southern California's Leonard Davis School of Gerontology, said evidence increasingly points towards a relationship between pollution exposure and dementia risk.

“There’s a lot we don’t understand yet, but we do know that the risk of dementia increases in proportion to the amount of air pollution,” he said.

Air Pollution & Dementia

Earlier research has identified mechanisms that link polluted air with neurological disease.

A study published in Environmental Pollution in May 2026 examined nearly 270,000 people over approximately 14 years. Greater exposure to PM2.5 led to structural changes in the hippocampus, a brain region responsible for learning and memory.

Inflammation and changes in fat metabolism appeared to explain the connection between pollution and dementia.

Another study, published in Science in 2025, examined hospital records from 56.5 million Americans between 2000 and 2014. It found that people living in areas with higher PM2.5 levels were more likely to be hospitalised with dementia with Lewy bodies and Parkinson's disease dementia.

Experiments in mice indicated that pollution exposure triggered abnormal folding and accumulation of alpha-synuclein, a protein that forms the deposits known as Lewy bodies. The animals also developed brain shrinkage, nerve-cell death and cognitive decline.

Xiaobo Mao, a study author and professor of neurology at Johns Hopkins University, said, “This is something we were so surprised to see.”

When researchers exposed mice that were genetically engineered without alpha-synuclein to the same pollution levels, a significant amount of damage was reduced. This suggested that the protein may play a role in the reduction.

In a separate experiment published in September 2026, researchers exposed mice to different airborne particles like diesel exhaust, dust collected from the World Trade Center site and wood smoke.

Diesel exhaust and World Trade Center dust changed more than 1,200 of the same genes, including genes involved in inflammation and amyloid processing.

Wood smoke did not produce changes related to Alzheimer’s. The researchers observed that diesel exhaust and World Trade Center dust contained more metals, cementing the possibility that certain components of pollution may contribute to neurological harm more than others.

How To Reduce Air Pollution Exposure

Individuals can take a few practical steps to reduce exposure to air pollution. These include improving ventilation when cooking, using appropriate indoor air filtration, replacing heating and ventilation system filters regularly and limiting prolonged exposure to outdoor pollution.

Mao said, “Indoor cooking may sometimes be worse than anything else.” He also emphasised that prevention involves maintaining a balanced diet, exercising and spending time outdoors when air quality is better.

An old idea deserves a second look: caring for others may be one of the most powerful ways to care for ourselves.

In traditional Indian homes, we were taught to care for and share with those around us: neighbours, the staff who worked for us, and the wider community we lived in. This was never thought of as charity. It was an everyday part of life, and it carried great value. The community was almost an extension of oneself and one's family.

The idea that the world is one family is not alien to India. The ancient Sanskrit concept of Vasudhaiva Kutumbakam captures it. Over time, as modern life moved faster, this belief slowly faded and self-care took priority. Today, self-care has become almost a global movement, full of advice on exercise, mindfulness, nutrition and stress reduction. Caring and sharing changed form and became "helping others". That was a welcome shift, because it still nudged us beyond our own wellbeing to do good for someone else.

Science Meets Ancient Wisdom

Remarkably, modern science is now bringing us full circle. A growing body of research confirms what philosophers, spiritual traditions and humanitarian organisations have long understood: when we serve others, we nourish ourselves.

The claim that helping others is the ultimate act of self-care may sound paradoxical.

Psychologists call it the "altruistic paradox". Altruism, the selfless concern for the welfare of others, appears at first glance to mean giving away our time, energy and resources. Yet people who volunteer, care, mentor, teach or serve their communities often receive a great deal in return. The rewards are not material. They are better mental, emotional, social and even physical health.

Studies in public health and psychology consistently link volunteering with greater happiness, stronger social connections, a stronger sense of purpose, lower levels of depression and higher life satisfaction. Some longitudinal studies even suggest that regular volunteering is associated with better physical functioning and lower mortality.

Why Does It Work?

Part of the answer lies in biology. Acts of kindness stimulate the release of "feel-good" chemicals in the brain, including dopamine, oxytocin and endorphins. This effect is often called the "helper's high".

Helping others also reduces loneliness and builds a sense of belonging, one of our deepest human needs. People who engage in meaningful service tend to report greater optimism, a clearer sense of purpose and more resilience in difficult times.

The benefits are especially significant in later life. Older adults who volunteer regularly report better emotional wellbeing, stronger social ties and less isolation. Retirement can leave a gap in identity and purpose, and service can fill that space with meaning and connection. Altruistic motivation itself seems to amplify these effects.

Service Above Self

Long before science confirmed these findings, humanitarian organisations built their philosophy around this truth. One of the finest examples are volunteer organisations like Rotary International, whose principal motto, "Service Above Self", has inspired generations of volunteers across the world. The motto expresses a simple belief: personal fulfilment and social progress are deeply connected.

Through projects that deliver safe drinking water, promote education, fight disease, build peace, protect the environment and support emotional health, Rotary members enrich societies every day. Behind these efforts are countless hours of selfless work that nurture human bonds, empathy and optimism.

A Remedy for Modern Times

Many of us are struggling with isolation, anxiety and constant tension. Active service is a powerful remedy. Whether we are tutoring a child, comforting an elderly neighbour, supporting someone's mental wellbeing, planting trees or guiding young people, these acts are much more than simple help. They are investments in shared and personal vitality.

Real self-care needs both inward reflection and outward engagement. Lifting those around us also lifts our own spirit. Dedicating ourselves to others gives us meaning, deepens our social ties and anchors us in a larger human family.

Ancient spiritual traditions and contemporary science arrive at the same insight: supporting others does not distract us from our own fulfilment. It is the most reliable foundation for it.

In an age of division, the quiet grace of helping someone else is a profound source of restoration, for our communities and for ourselves.

Lemon water may help reduce the risk of certain types of kidney stones, particularly calcium oxalate stones, but it is not a guaranteed preventive remedy. Lemons contain citrate, a naturally occurring substance that can bind with calcium in urine and help inhibit the formation and growth of some kidney stones.

Drinking lemon water can also support prevention by encouraging greater fluid intake. Adequate hydration increases urine volume, diluting substances such as calcium and oxalate that can crystallise and form stones. However, the benefit depends on the amount consumed, individual urinary chemistry and the type of stone a person is prone to developing.

What Are the Symptoms of Kidney Stones?

Common symptoms of kidney stones include severe pain in the back or flanks that may radiate to the groin, pain while urinating, blood in the urine, nausea and vomiting. Some small stones may pass without causing noticeable symptoms, while larger stones can obstruct the urinary tract and cause significant pain.

If kidney stone symptoms occur alongside fever, chills or difficulty passing urine, seek urgent medical attention. These symptoms may indicate an obstruction or infection that requires prompt treatment. A healthcare professional may recommend urine tests, blood tests or imaging to determine the stone's size and location.

It is important to understand that lemon water is not a substitute for medical treatment or personalised dietary advice. Adding lemon to water without excessive sugar and salt is a practical option, but commercially prepared lemon drinks may contain added sugar, which is best limited. Lemon water may also aggravate acidity or heartburn in some individuals.

There is no universally established amount of lemon water that guarantees kidney stone prevention. The priority is to drink enough fluids to maintain adequate urine output, with individual requirements varying according to climate, physical activity and medical conditions. People who have been advised to restrict fluids because of kidney or heart conditions should follow their healthcare professional's recommendations rather than increasing their intake independently.

Who Should Take Extra Precautions?

People with a history of recurrent kidney stones should consult a healthcare professional to identify the stone type and understand their specific risk factors. Depending on the findings, they may need tailored fluid intake, dietary modifications or medication. A 24-hour urine test may also help identify substances that contribute to stone formation and guide preventive measures.

Adequate water intake remains the cornerstone of kidney stone prevention, while lemon water can be a useful addition to a balanced hydration routine. However, its effectiveness varies from person to person, and those at high risk of recurrence may need more targeted preventive strategies.
