The air quality index (AQI) has worsened in Delhi-NCR in the past few days with the Commission for Air Quality Management (CAQM) invoking stage two of the anti-pollution plan Graded Response Action Plan (GRAP). Doctors and experts have also taken note of the rise in pollution, and have observed diseases they have not seen before.

Dr Sanjay Jain, a Delhi-based ENT and a member of DocTube also noted an increase in the number of patients with respiratory issues. "I have seen a notable increase in patients with upper respiratory tract infections, chronic sinusitis, and allergic rhinitis, which are directly linked to rising pollution levels," he says. From his experience, he has noticed a rough increase of 30 to 40% of patients with pollution-related ENT issues.

What Is The Administration Doing?

As per the System of Air Quality and Weather Forecasting and Research (SAFAR), the AQI in Delhi at 8 am today was recorded at 317, which falls under the "very poor" category. The India Meteorological Department (IMD) has predicted that the average AQI will stay in the "very poor" category in the coming days.

GRAP accounts for the restrictions on the usage of coal and firewood, and diesel generator sets in the Delhi-NCR. Furthermore, plans for mechanical sweeping and water sprinkling on the identified roads will also be carried on a daily basis. The plan expands to dust control measures at the construction and demolition sites too.

Parking fees will also be increased to discourage private transport with additional buses and metro services to start soon.

Source Of Pollution

A study titled What Is Polluting Delhi's Air? A Review from 1990 to 2022 mentions that Delhi's major contributor is road transport, while the second major factor comes from burning agricultural waste or stubble. Other factors like waste management, the construction sector, roads, and firecrackers during Diwali also lead to the increase in pollution.

Health Issues

Delhi pollution is more dangerous than we think. Not just breathing issues, but it can also lead to lung cancer and heart diseases. Studies have shown that prolonged exposure to pollution can lead to a reduction in lung function and also premature death, especially in children. It can also lead to increased risks of stroke, cognitive decline, and even pregnancy complications.

Doctors also take note of other pollution-related issues that were not seen before or are unusual. Dr Jain says that prolonged exposure to pollution can cause chronic ear infections in children due to inflammation in the Eustachian tube. "This is not commonly recognised by the people," he says. Dr Brunda MS, senior consultant, of internal medicine at Aster CMI Hospital in Bengaluru also explains that many people remain unaware of the health issues associated with pollution. Apart from shortness of breath, environmental toxins can cause brain diseases and reproductive health issues. "The subtle and slow effects of pollution often lead Understanding these relationships can help communities promote cleaner, more resilient environments," explains the doctor.

The doctor also explains the impact of pollution on the eyes as it can cause conjunctivitis or worsen any pre-existing eye infection. Dr Brunda MS also mentions that air pollution is responsible for 1.67 million deaths in India, which is 17.8% of the total deaths in the country. "There has been a 3 to 4% increase in a number of cases because of pollution," the doctor explains.

How To Stay Safe?

Dr Jain explains the precautions one can take to stay safe and prevent these diseases from happening. "Individuals can protect themselves by wearing masks, using air purifiers at home, avoiding outdoor activities during high-pollution days, and maintaining a healthy lifestyle," he explains.

The doctors also recommend wearing N95 masks, surgical masks or equivalent for effective filtration of airborne particles, consuming warm fluids and herbal teas and eating food rich in vitamin C and antioxidants that will help reduce inflammation and protect mucous membranes in the throat.

Imagine stubbing your toe and feeling like it's been set on fire... for months. Now imagine that burning sensation spreading to your entire leg, and instead of easing over time, it gets worse. That’s Chronic Regional Pain Syndrome (CRPS). It is a condition as problematic as its name suggests and yet, bizarrely, not talked about enough.

Chronic Regional Pain Syndrome is a long-term, often debilitating condition that typically affects a limb like an arm, hand, leg, or foot after an injury, surgery, stroke, or even something as mundane as a sprain. It’s like your nervous system gets stuck in panic mode.

There are two types:

Type 1 (Reflex Sympathetic Dystrophy): Happens without a confirmed nerve injury.

Type 2 (Causalgia): Involves a definite nerve injury.

Regardless of type, the result is the same: persistent, severe pain way out of proportion to the initial injury, often with odd side effects.

Why CRPS Is No Ordinary Ache

If pain had a reality show, CRPS would be the melodramatic diva. The pain can feel like burning, stabbing, throbbing, or shooting. It’s often accompanied by:

• Swelling
• Changes in skin colour or temperature (hot and red one minute, cold and blue the next)
• Excessive sweating
• Hair and nail changes
• Muscle weakness and spasms

It can also cause allodynia, which is a fancy term for when even a gentle breeze or the touch of fabric feels like torture.

Worst of all? The pain doesn’t stay neatly in one place. It may start in a toe and sneakily creep up the leg or even jump to the other side of the body.

Why It Happens

Ask ten doctors what causes CRPS, and you might get eleven guesses. The exact cause isn’t fully understood, but it seems to involve:

• A malfunction in the peripheral and central nervous systems
• Abnormal inflammatory responses
• Dysfunction of blood vessels and pain pathways
• It’s the body’s overreaction to trauma, like a car alarm blaring long after the bump is gone.

Life with CRPS

Chronic pain doesn’t just hurt the body; it impacts daily life. CRPS affects every layer of existence:

• Mental health: Anxiety, depression, and even PTSD-like symptoms are common.
• Mobility: Limited range of motion and muscle weakness may lead to reliance on walking aids or wheelchairs.
• Sleep: Pain that flares up at night makes good sleep feel like a luxury.
• Work and relationships: Jobs may be lost, plans cancelled, social life drained.

What adds to the distress? Many people with CRPS report feeling disbelieved, even by medical professionals. It’s an invisible illness with painfully visible consequences.

How Do You Treat It?

There’s no one-size-fits-all cure, but the goal is to reduce symptoms and improve quality of life. Treatment is usually multi-pronged:

• Medications: Pain relievers, nerve-blockers, antidepressants, anticonvulsants
• Physical therapy: To restore mobility and function
• Occupational therapy: To adapt daily tasks
• Psychological support: Pain management techniques like CBT and mindfulness
• Interventional approaches: Nerve blocks, spinal cord stimulation, or ketamine infusions in severe cases

Early diagnosis is key. The longer CRPS goes untreated, the more entrenched and resistant it becomes.

CRPS Is Real, Rare, and Relentless

Though CRPS is considered rare, with estimates suggesting around 5 to 26 cases per 100,000 people annually, it’s devastating for those who live with it. It often shows up uninvited, stays far too long, and brings along a suitcase full of complications.

But awareness is growing. Support groups, research into new treatments, and advocacy efforts are helping give a voice to people who’ve lived in silence. With the right treatment plan, support system, and a dash of stubborn hope, many people find ways to live well despite the pain.

We have all had that mini meltdown finding a clump of hair in the shower drain or a brush full of hair after combing hair. While blaming stress or the changing seasons feels comforting, experts warn that your body might be sounding a nutritional alarm. Yes, your hair loss might be less about the weather and more about what is missing from your plate.

Listen to What Your Body’s Saying

“Seeing a lot of hair strands on your pillow cover feels distressing,” says Dr Khushboo Jha, MBBS, MD, Chief Dermatologist Consultant at Metro Hospital and Founder of One Skin Clinic, Faridabad, “but you need to listen to your body. It’s the way it communicates that your body is struggling with some deeper concern, probably nutrient deficiency.”

Hair, it turns out, is a high-maintenance tissue. It’s fast-growing and metabolically active, demanding a steady supply of nutrients. But it’s not considered essential for survival. So in times of nutritional crisis, your body reroutes vitamins and minerals to more important organs like your heart or brain, leaving your hair stranded without support.

“If your diet is insufficient, especially lagging in iron, vitamin D, Vitamin B complex such as vitamin B12 and biotin, zinc, protein, etc., hair will be the first one to suffer,” says Dr Jha.

Why Vegans, Crash Dieters, and IBS Patients Should Pay Extra Attention

Dr Ameesha Mahajan, Cosmetic Dermatologist and Founder of Eden Skin Clinic, agrees. “Vegetarians or vegans are more prone to deficiencies, especially when it comes to vitamin B12, iron and protein deficiency,” she says. And it’s not just about what you eat, but also how well your body absorbs it. “Impaired gut absorption disorders such as coeliac disease or IBD… can lead to extreme hair thinning,” Dr Mahajan adds.

Crash diets and eating disorders like bulimia nervosa don’t do your strands any favours either. These behaviours disrupt the body’s nutritional balance and can prematurely push hair into the shedding phase.

The Medical Jargon You Didn’t Know You Needed: Telogen Effluvium

One particular fallout of nutrient shortfalls is telogen effluvium, a name for hair falling out sooner than it should. Dr Mahajan points to iron deficiency anaemia as a common trigger. “It is strongly associated with telogen effluvium, a condition where hair prematurely enters the shedding phase,” she explains.

In other words, if you’ve been feeling unusually tired and your hair is thinning, it might be more than a coincidence; it could be low iron or another nutrient throwing your hair growth cycle off track.

Don’t Pop Just Any Pill

Before you go on a supplement shopping spree, both experts urge caution. “Before self-prescribing supplements, experts urge a full nutritional workup to identify what’s missing,” says Dr Jha. Overloading on certain vitamins can do more harm than good.

Dr Mahajan agrees. “It’s best to get blood parameters checked for any nutrient deficiencies before beginning any supplement to be sure.”

So yes, multivitamins are tempting but flying blind could backfire. Know what you’re low on before topping up.

Eat for Your Hair: What to Load on Your Plate

Both dermatologists suggest nourishing your scalp from within. Dr Jha recommends “a diet loaded with whole grains, legumes, millets, dairy products, nuts, seeds, etc.,” noting these support not only hair health but also overall wellbeing.

Dr Mahajan says that these foods “help to restore the lost nutrients, making the hair denser and thicker.” Think of them as edible armour for your follicles.

Still Losing Hair? Time to Dig Deeper

If your hair continues to vanish despite eating all the right things, don’t ignore it. “If still you face symptoms, consult a dermatologist for ruling out hormonal or other health conditions,” advises Dr Jha.

Dr Mahajan adds, “If you still suffer from hair fall, despite making changes in your diet, it’s time to consult a dermatologist, as it might be due to some hormonal disruption or any other autoimmune-related cause.” Because sometimes, hair loss isn’t just about what’s missing but what’s going wrong beneath the surface.

Heart disease remains one of the leading causes of death globally, and while technology has evolved to the point where predicting heart attacks is possible, the medical world still struggles to put this into practice. Experts point to both promise and pitfalls in predictive cardiology, revealing why such life-saving tech is not yet a mainstream reality.

The Tech Is Here, But We Are Not Using It Enough

Dr. Vikrant B. Khese, Cardiologist at Jehangir Hospital, Pune, says the idea that we can predict heart attacks before they happen is both “exciting and frustrating, because while the technology exists, its real-world implementation remains limited.”

He explains that artificial intelligence (AI) and machine learning (ML) have incredible potential in this field. These tools can analyse vast datasets, such as blood pressure, lipid profiles, ECGs, imaging, and even genetic markers, to uncover patterns that might be invisible to the human eye. “These tools can detect subtle risk factors that may be missed in routine clinical practice. However, several challenges continue to hold us back,” he says.

One of the biggest concerns is the source of the data feeding these algorithms. “The majority of AI models are trained on Western datasets that do not reflect the unique genetic, environmental, and lifestyle factors of Indian or Asian populations. This creates a mismatch, resulting in lower accuracy and reliability for non-Western patients.”

Dr. Khese adds that cardiovascular disease is deeply multifactorial. It is not just about clinical metrics. “Stress, socioeconomic status, cultural diet patterns, air pollution, and unstructured physical activity all influence risk but are difficult to quantify in a dataset. AI still struggles with these intangible but crucial variables.”

And even when predictive tools are developed, another hurdle lies in the healthcare system’s ability to use them. “Data-driven predictions can only be as good as the data input. In India, inconsistent electronic medical records, underreporting, and fragmented healthcare systems make it harder to gather high-quality longitudinal data, limiting the AI's learning potential.”

Crucially, there is also a behavioural gap. “Even when prediction tools exist, they are not routinely used by clinicians due to scepticism, lack of training, or workflow disruption. Bridging the gap between innovation and implementation is a major hurdle.”

According to Dr. Khese, technology must complement clinical judgement, not replace it. “AI is a powerful tool but not a standalone solution. Until we combine high-quality, representative data with clinical wisdom and system-level integration, the promise of predicting heart attacks before they happen will remain underutilised. The future lies in synergy; technology must empower doctors, not replace them.”

Prediction Tools Exist—But We’re Waiting for Symptoms

Dr. Vijay D'Silva, Medical Director of White Lotus International Hospital and Clinical Advisor and Mentor of Heartnet India, backs this view and draws attention to major international trials. “Research from the University of Oxford has suggested that a global trial of an AI tool that can predict the 10-year risk of heart attack has shown that in about 45 per cent of patients with chest pain, treatment could be improved,” he shares.

“Early detection of cardiac risk allows timely treatment and monitoring that can help reduce the mortality rate,” he says, explaining that most coronary blockages are asymptomatic. “Some present with chest, arm or jaw pain on exertion (angina pectoris). Few present as a heart attack or sudden death. People seek treatment after a heart attack when the damage is already done.”

According to Dr. D’silva, “With the help of the right tools, it is now possible to predict a heart attack before it occurs.” Among these tools are blood tests, ECGs, and advanced risk calculators such as the AHA PREVENT calculator, ASCVD Risk Calculator Plus, QRISK3, and SCORE2.

He points out how the 2023 AHA PREVENT calculator estimates 10-year cardiovascular risk in individuals aged 30 to 79, and 30-year risk in adults aged 30 to 59. “Early-stage detection of CVD minimises the cost and also reduces the CVD mortality rate,” he says.

This tool divides patients into four risk categories, each with its own treatment strategy:

• Low risk (<5%): Maintain healthy lifestyles and reassess every five years.
• Borderline risk (5–7.4%): Lifestyle changes and monitoring of risk-enhancing factors like BP, sugar, weight and lipids. CAC scoring can further stratify risk. Annual reassessment recommended.
• Intermediate risk (7.5–19.9%): Calls for lifestyle management, preventive medication (statins or aspirin), stress testing and CT coronary angiogram. Yearly reassessment is needed.
• High risk (≥20%): Requires intensive lifestyle changes, pharmacotherapy, imaging and close follow-up.

Despite these advances, Dr D'Silva says, “The gap lies in implementation. Most people still wait for the symptoms to appear before seeing a doctor. Heart attacks, unfortunately, strike without any warning, especially in women and younger patients, where symptoms can be atypical.”

He stresses that predictive cardiology is not yet standard in clinical practice. “People who are at risk seek care when symptoms arise. But in cardiology, symptoms often come too late. Up to 50 per cent of heart attack victims had no prior warning signs.”

Why Risk Calculators Are NotFoolproof

• Patients with LDL cholesterol ≥190 mg/dL
• Those with familial hypercholesterolemia
• Patients with type 1 diabetes
• People with other risk-enhancing factors like family history of early cardiovascular disease, metabolic syndrome, chronic kidney disease, chronic inflammatory diseases (psoriasis, RA, lupus), or early menopause

The Way Forward

Dr. D'silva concludes, “The ability to predict heart attacks is advancing continuously, but we need public awareness and equitable access to make predictive cardiology more standard.”

In short, we can predict heart att but until we normalise risk screening, improve data systems, and bridge the clinical gap, too many heart attacks will continue to catch people and systems off guard.
