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.

India is only second in the world to have people with chronic kidney diseases in 2023, said The Lancet study. In 2023, China recorded 152 million patients with chronic kidney disease (CKD), while India was at 138 million.

The study, led by researchers from the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, along with collaborators in the U.S. and the U.K., found that CKD was the ninth-leading cause of death worldwide, claiming nearly 15 lakh lives in 2023.

Regionally, the highest prevalence was reported in North Africa and the Middle East (18% each), followed by South Asia (nearly 16%), and more than 15% in Sub-Saharan Africa, Latin America, and the Caribbean.

In fact, senior director and HOD Nephrology at Medanta Kidney and Urology Institute, Dr Shyam Bansal says, "Chronic kidney disease is one of the fastest-growing chronic illnesses in India, mainly because diabetes and hypertension are becoming more common. Diabetes now affects about 10% of the population and hypertension nearly 25%, and together they remain the leading causes of kidney disease."

The report also highlighted CKD’s strong link to heart disease. It contributed to almost 12% of global cardiovascular deaths in 2023 and ranked as the seventh-leading cause of heart-related mortality, ahead of diabetes and obesity.

The researchers outlined 14 key risk factors for CKD, with diabetes, hypertension, and obesity contributing the most to the loss of healthy life. Dietary habits—such as low intake of fruits and vegetables and high sodium consumption, also played a significant role in raising CKD risk.

“Chronic kidney disease is both a major risk factor for other leading causes of health loss and a significant disease burden in its own right. Yet, it continues to receive far less policy attention than other non-communicable diseases, even as its impact grows fastest in regions already facing the greatest health inequities,” said senior author Theo Vos, professor emeritus at IHME.

The findings draw on data from the Global Burden of Disease (GBD) 2023 study, which tracked trends in diseases, injuries, and health risk factors across 204 countries and territories from 1990 to 2023.

Importance of Early Detection Of Chronic Kidney Disease

Importantly, the authors noted that most people with CKD in 2023 were in the early stages, highlighting the urgent need for strong screening programmes and strategies to reduce risk before the disease advances.

This is why its early diagnosis is utmost important. Dr Bansal on the need for early detection says, "“The biggest challenge is identifying people at risk as early as possible. Early diagnosis and timely control of risk factors are essential if we want to slow the progression of chronic kidney disease."

Early detection could also reduce heart-related deaths due to kidney disease and delay one's requirement for replacement therapies, which is usually sought in advanced stages of the disease.

Dr Bansal also points out that early detection could help one live a better life and also in many ways reduce the burden on the Indian healthcare system, and save cost. "We are dealing with a large population at risk, and kidney disease is complex and costly to treat. While infrastructure and specialist availability are improving, managing this growing burden remains a significant challenge," he says.

A GP has raised concern about a key sign that may show you have Covid rather than a cold or flu. Winter illnesses often look alike, which makes it hard to tell them apart, and getting the right diagnosis is important for proper care. Dr Rupa Parmar, GP and medical director at Midland Health, explained that there are certain clues that can help people understand what they are dealing with. She advised that anyone unsure should check with their doctor, as it is safer to ask than ignore a concern.

Why Breathlessness Matters

Dr Parmar noted that shortness of breath stands out as a sign of Covid. It rarely appears in a cold or flu, but it is common with Covid because the infection tends to affect the lungs and cause inflammation. The NHS also lists breathlessness as a sign linked more strongly with Covid than with flu or a cold. This symptom is also seen in conditions such as respiratory syncytial virus. In some cases, people with the flu who do not recover and worsen may develop breathing trouble if they develop complications such as pneumonia.

How Cough Patterns Differ

She added that coughs appear in all three infections, but they do not sound the same. A cold usually causes a light cough, flu tends to bring a dry one, and Covid usually causes a dry, ongoing cough. Many people with Covid cough for more than an hour or have several episodes of coughing through the day.

Loss Of Taste Or Smell As A Warning Sign

Another clue is a change in taste or smell. Dr Parmar said this sign is more specific to Covid. A sudden loss of taste or smell, or even a noticeable change, is more likely linked to the coronavirus. She explained that the pattern of symptoms often helps point to the right illness. A mild cough and sore throat usually fit a cold, a fever and strong fatigue suggest flu, and a loss of smell or taste with a steady cough point to Covid.

How Symptoms Begin And Progress

She also noted that the start of symptoms can differ. A cold tends to appear slowly, flu symptoms usually show up quickly within a few hours, and Covid can begin with mild signs that grow stronger over time. A cold mainly affects the nose and throat, while flu and Covid can cause symptoms across the body.

What To Do If You Have Covid Symptoms

Even though there are no formal self-isolation rules anymore, the NHS advises people to stay home and limit contact with others if they or their children have symptoms and either have a high temperature or feel too unwell to manage daily activities at work, school, or home. The NHS states that people can return to their usual routine once they feel well again or no longer have a high temperature.

As winter settles in, many people sense a shift in their mood. Shorter days and colder weather often leave us feeling a little dull. In some cases, this may be linked to seasonal affective disorder (SAD). Yet there may also be another explanation.

A doctor has cautioned that a very common deficiency could be the reason you have been feeling unusually low. He noted that this problem affects well over a billion people around the world.

Iron Deficiency Might Be The Reason Behind Your Low Mood

In a TikTok video, Doctor Sermed Mezher raised concern about iron deficiency. Iron is a mineral the body relies on to move oxygen through the blood and support several important processes. Dr Mezher explained as per Express, “Low iron is the most common nutritional deficiency in the world, affecting more than one billion people.” He also described how it can influence dopamine, often referred to as the “feel-good” chemical.

He added, “And its effects on dopamine go way deeper than just oxygen transport. Dopamine is made from an amino acid called tyrosine over a couple of steps, and the enzyme involved in the first step needs iron to work properly. It is no surprise, then, that in iron deficiency, studies show problems in dopamine pathways that play a part in happiness, reward, self control and social behaviour.”

The positive news is that this can usually be managed. Dr Mezher said, “Once your iron levels are restored, these pathways return to their normal state, and you can help this process by taking iron with vitamin C and staying away from caffeinated drinks for two hours before and after.”

Symptoms Of Iron Deficiency

The NHS lists several signs of iron deficiency anaemia, including:

• Tiredness and low energy
• Shortness of breath
• Heart palpitations
• Paler skin
• Headaches

If you think you may be low in iron, you should talk to your GP. A simple blood test can confirm it.

How To Boost Iron Levels?

Iron levels can be raised through the foods you eat. These options are naturally rich in iron:

• Dark-green vegetables such as watercress and curly kale
• Iron-fortified cereals and bread
• Meat
• Dried fruits like apricots, prunes and raisins
• Pulses including beans, peas and lentils

The NHS also suggests cutting back on:

• Tea
• Coffee
• Milk and dairy products
• Foods high in phytic acid, like wholegrain cereals, which can prevent your body from absorbing iron from meals and supplements

The NHS notes, “Large amounts of these foods and drinks make it harder for your body to absorb iron. You might be referred to a specialist dietitian if you're finding it hard to include iron in your diet.”

How Much Iron Does One Need?

The daily iron requirement is:

• 8.7mg for men aged 19 and above
• 14.8mg for women aged 19 to 49
• 8.7mg for women aged 50 and above

The NHS adds, “Taking 17mg or less a day of iron supplements is unlikely to cause any harm. But continue taking a higher dose if advised to by a GP.”
