Indians battle respiratory issues, skin rashes in world's most polluted town
Two-year-old Sumaiya Ansari, a resident of India's Byrnihat town, ranked the world's most polluted metropolitan area by Swiss Group IQAir, was battling breathing problems for several days before she was hospitalised in March and given oxygen support.
She is among many residents of the industrial town on the border of the northeastern Assam and Meghalaya states - otherwise known for their lush, natural beauty - inflicted by illnesses that doctors say are likely linked to high exposure to pollution.
Byrnihat's annual average PM2.5 concentration in 2024 was 128.2 micrograms per cubic meter, according to IQAir, over 25-times the level recommended by the WHO.
PM2.5 refers to particulate matter measuring 2.5 microns or less in diameter that can be carried into the lungs, causing deadly diseases and cardiac problems.
'It was very scary, she was breathing like a fish,' said Abdul Halim, Ansari's father, who brought her home from hospital after two days.
According to government data, the number of respiratory infection cases in the region rose to 3,681 in 2024 from 2,082 in 2022.
'Ninety percent of the patients we see daily come either with a cough or other respiratory issues,' said Dr. J Marak of Byrnihat Primary Healthcare Centre.
Residents say the toxic air also causes skin rashes and eye irritation, damages crops, and restricts routine tasks like drying laundry outdoors.
'Everything is covered with dust or soot,' said farmer Dildar Hussain.
ritics say Byrnihat's situation reflects a broader trend of pollution plaguing not just India's cities, including the capital Delhi, but also its smaller towns as breakneck industrialisation erodes environmental safeguards.
Unlike other parts of the country that face pollution every winter, however, Byrnihat's air quality remains poor through the year, government data indicates.
Home to about 80 industries - many of them highly polluting - experts say the problem is exacerbated in the town by other factors like emissions from heavy vehicles, and its 'bowl-shaped topography'.
'Sandwiched between the hilly terrain of Meghalaya and the plains of Assam, there is no room for pollutants to disperse,' said Arup Kumar Misra, chairman of Assam's pollution control board.
The town's location has also made a solution tougher, with the states shifting blame to each other, said a Meghalaya government official who did not want to be named.
Since the release of IQAir's report in March, however, Assam and Meghalaya have agreed to form a joint committee and work together to combat Byrnihat's pollution.

Debunking Myths About Smartphones and Brain Tumors
Last Updated: While concerns persist, experts affirm that mobile phones emit non-ionizing radiation at safe levels, with no conclusive evidence linking them to serious health risks like cancer. Many people recognize the personal benefits of mobile services, though the public may also express concerns about possible risks from the radio signals used by mobile devices. Research across several countries indicates that a significant percentage of the population has a limited understanding of how mobile phones operate and how levels of radio signals are regulated and controlled. Some individuals may have encountered claims suggesting potential risks from long-term mobile phone use or that certain people are more sensitive to radio signals. Mobile phone users may attribute certain symptoms to their phone usage. Parents, while acknowledging the personal safety benefits mobile phones offer their children, may simultaneously worry about possible health risks. Dr. Rvaikanth Vuppu, Consultant – Neuro and Spine Surgeon, Manipal Hospital, Vijayawada, shares all you need to know: A mobile phone is a low-power radio transmitter that, under good network coverage, operates at levels similar to those of a cordless home phone. Mobile phones are tested for compliance at maximum power, and international exposure guidelines are designed to be protective of all individuals. If users remain concerned, they can reduce their exposure by using a hands-free kit or limiting the duration of calls. Cancer is another health concern often raised in the context of 5G deployment, both by the public and researchers. Numerous studies have examined the effects of radiofrequency (RF) electromagnetic fields (EMF) on humans, with mixed results. In 2011, the World Health Organization (WHO)/International Agency for Research on Cancer (IARC) classified RF electromagnetic fields as possibly carcinogenic to humans, based on an observed increased risk for glioma — a malignant form of brain cancer — linked to wireless phone use. For example, Carlberg and Hardell (2017) concluded that RF radiation should be considered a human carcinogen due to its potential to cause glioma. In contrast, Vila et al. (2018) found no clear association between RF or intermediate frequency (IF) EMF exposure and glioma or meningioma. These contradictory findings underscore the need for further research to assess whether 5G could contribute to cancer development. Concerns about 5G and DNA damage stem from misunderstandings about radiation. For many people, the term 'radiation" evokes alarming associations with nuclear disasters or cancer. However, only higher-frequency radiation, such as ultraviolet (UV), X-rays, and gamma rays, is ionizing — meaning it can break molecular bonds and damage DNA. The radio waves used in 5G technology are non-ionizing and lack the energy to cause such damage. The non-ionizing nature of 5G means it cannot physically cause cancer in the same way ionizing radiation might. This distinction is critical: while 5G uses radiofrequency radiation, it operates at power levels far below those capable of harming biological tissue or altering DNA. Regarding the IARC classification: On May 31, 2011, radiofrequency electromagnetic fields were classified as possibly carcinogenic to humans (Group 2B), based on limited evidence of increased risk for glioma and acoustic schwannoma, both associated with long-term wireless phone use. However, for other types of cancer and environmental or occupational exposures, the evidence was deemed inadequate. The IARC summary notes indications of increased glioma risk among individuals in the highest 10% of cumulative phone use. However, researchers did not observe a consistent trend of increasing risk with greater duration of use. The conclusions were tempered by potential biases and errors, which limit the strength of the findings and preclude a definitive causal interpretation. In response, many health authorities have emphasized the need for further research while reaffirming that individuals can take practical steps to reduce mobile phone exposure. Importantly, the WHO continues to support the adoption of international RF-EMF exposure limits as a precautionary measure. First Published:

How to manage high blood pressure with simple lifestyle tweaks
Just under a month ago, the world celebrated Hypertension Day on May 17. Considering an even more recent report published by online medical site Healio, Hypertension unawareness rose from 2013 to 2023, you might reason that having a day just for this condition that silently creeps on us is essential. Furthermore, a May 2024 WHO (World Health Organisation) report states that Indians have been consuming nearly twice the recommended amount of sodium (10.98 gms). And this is making the population more susceptible to high blood pressure (hypertension). WHO's recommendation is to use Lower Sodium Salt Substitutes (LSSS). Unavoidable as hypertension or blood pressure is, Lounge spoke to experts to know if there are simple tweaks you could make to your daily to control this condition before it turns severe. Also read: A guide to understanding inflammation and ways to combat it's negative effects 'While the risk of developing hypertension increases as one ages, recent research has revealed alarming statistics about its prevalence among Indian adolescents, with rates as high as 25 per cent. That's why it's important for people with a family history of diabetes and hypertension to start getting regular BP checks in their mid-20s. Others can wait until their early 30s to start testing for hypertension," says Dr Anuja Agarwala, vice president, Indian Dietetic Association, Delhi. According to Agarwala, parents should be aware that hypertension can exist in children too. So, if high blood pressure and cardiovascular diseases run in the family, schedule regular BP checks for your children too. SYMPTOMS 'About a decade back, hypertension would happen to those in their 50s. These days, due to high stress, lifestyle, genetic factors and addictions, people are getting hypertension at even 28. And the risk is higher if you're obese," notes Dr Swarup Swaraj Pal, head of cardiovascular and thoracic surgery at Gleneagles Hospital, Mumbai. Pal explains that hypertension happens when calcium gets deposited in the lining of the blood vessels, causing it to harden. This adds pressure to the heart as it's pumping harder. If left unattended, this can eventually result in cardiovascular disease. The most common symptoms of hypertension, according to Pal, are sleep deprivation, an inability to focus, throbbing headaches and fluctuation in energy levels. More serious symptoms could include blacking out and being on the verge of collapsing. 'Get your blood pressure checked every three-six months, especially if you're above 30," he advises, and reiterates that the risk of one being affected by hypertension is high if you have parents who are obese or have a history of heart disease. 'While women are more or less protected by the hormone estrogen till age 45 or 50, after menopause, they too are at a risk of suffering from hypertension," Pal adds. Hypertension, Agarwala says, manifests in symptoms as small as headaches. 'What makes it particularly dangerous is that it does not cause specific symptoms until it's too late. If not managed well, hypertension can lead to serious health issues, such as heart disease, stroke and kidney disease," she cautions. Also read: Why short bursts of cold showers are good for you WAYS TO MANAGE HYPERTENSION Apart from medication, Agarwala's top tips for managing hypertension naturally include quitting drinking and smoking; getting adequate sleep for about eight hours; reducing exposure to stressful environments– if your work environment is stressful, step out every four hours or so; and exercise three-four times a week. She cannot stress enough about the importance of physical exercises. 'It is important to make time for it at least 3-4 times a week. But those who are unable to dedicate time for exercise should try and include more walking into their daily routine. Walking 10,000 steps a day is considered beneficial for your cardiovascular health." It's also crucial to be aware of how sodium insidiously adds up in your diet. It might be the chutney you eat at lunch or those rice crackers you have at tea. According to Agarwala, including fruits and vegetables in your diet is another effective way to maintain healthy blood pressure. GET CREATIVE WITH INGREDIENTS Mysuru-based Dr. Jamuna Prakash, former professor, food science and nutrition, University of Mysore, says, managing hypertension isn't about entirely cutting out namkeens us Indians are so fond of from our diet, but consuming it judiciously. 'Whilst cooking, pairing salt with low-sodium seasonings like MSG (monosodium glutamate), along with an assortment of herbs and spices, can bring out an ideal balance of umami, saltiness, and other traditional Indian flavors—making for a satisfying meal without the need for additional sodium," she says. Adding smokiness to your paneer and chicken preparations can provide additional complexity to the flavor profile of the dish, says Mumbai-based chef Ajay Chopra. 'Borrowing from culinary practices around the world, like using kombu or seaweed broth, as done in Japan, can create umami in certain soups and curries. Adding lemon juice is another way to add flavour to your dishes, and stimulate your taste buds," he notes. Sumitra Nair is an independent journalist based in Kochi.

MORE Every year on June 7th, the global community observes World Food Safety Day, a United Nations initiative aimed at raising awareness about the importance of food safety and inspiring action to prevent, detect, and manage foodborne risks. With the theme for 2025 being 'Food Safety: Prepare for the Unexpected,' this year's commemoration focuses on enhancing the resilience of food safety systems in the face of emergencies, whether caused by natural disasters, economic crises, or global pandemics. World Food Safety Day, established in 2018 by the United Nations General Assembly and led jointly by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO), underscores that food safety is everyone's business—from farm to fork. With 600 million cases of foodborne illnesses annually, the stakes are high. This article delves into the significance of World Food Safety Day, the current global challenges, and the shared responsibility in ensuring that the food we eat is safe. The Global Burden of Unsafe Food Unsafe food is a silent epidemic. According to WHO, 1 in 10 people worldwide fall ill after consuming contaminated food, and an estimated 420,000 die every year. The most vulnerable are children under five, who account for 40% of the foodborne disease burden, resulting in 125,000 deaths annually. Foodborne illnesses can be caused by bacteria, viruses, parasites, or chemical substances entering the food chain. Common culprits include Salmonella, E. coli, Listeria, and noroviruses. In low- and middle-income countries, poor infrastructure, lack of awareness, and weak regulatory systems often exacerbate the problem, turning preventable health risks into deadly threats. But food safety is not only a health issue—it is an economic and social one. Unsafe food restricts global trade, reduces productivity, and places a burden on healthcare systems. The World Bank estimates that foodborne illnesses cost low- and middle-income economies around $95 billion a year in lost productivity. Why Food Safety Matters More Than Ever In an increasingly globalized food system, ingredients and final products cross multiple borders before reaching consumers. A fruit snack made in one country might contain nuts from another, sweeteners from a third, and be packaged in a fourth. This global complexity, while economically efficient, introduces many opportunities for contamination or error. Furthermore, climate change has intensified the challenge. Rising temperatures and shifting weather patterns can promote the spread of foodborne pathogens and mycotoxins. Insects, pests, and fungal diseases are also on the rise, threatening the integrity of crops and food supply chains. The COVID-19 pandemic was another stark reminder of the vulnerability of food systems. Though not a foodborne virus, the pandemic disrupted food processing, transport, and retail systems. It highlighted the importance of emergency preparedness, supply chain traceability, and public communication during health crises—all crucial themes for this year's observance. 2025 Theme: 'Food Safety: Prepare for the Unexpected' The 2025 theme highlights the need for resilient food safety systems that can withstand unexpected challenges, including natural disasters, pandemics, cyberattacks, and supply chain disruptions. Emergencies can disrupt food production and inspection processes, compromise cold chains, and overwhelm regulatory agencies, potentially leading to significant food safety issues. Whether it's a power outage that spoils stored meat or a flood contaminating water sources used in irrigation, being prepared is key. Governments and businesses are encouraged to invest in: Risk-based inspection systems Data-sharing platforms for real-time alerts Public education campaigns Robust traceability systems Contingency planning and crisis simulations As the FAO aptly puts it: 'Safe food allows for the uptake of nutrients and promotes long-term human development.' Preparedness ensures that this fundamental right is not interrupted, even in times of crisis. The Five Keys to Safer Food The WHO promotes a set of practical principles known as the 'Five Keys to Safer Food', which are crucial for food handlers at every level—from household kitchens to commercial processors: Keep Clean: Wash hands, surfaces, and equipment frequently. Separate Raw and Cooked Foods: Prevent cross-contamination by using separate utensils and storage. Cook Thoroughly: Ensure the food reaches a safe internal temperature. Keep Food at Safe Temperatures: Avoid the 'danger zone' (4°C–60°C) where bacteria multiply rapidly. Use Safe Water and Raw Materials: Select fresh, wholesome ingredients and ensure the quality of the water used. These five principles are deceptively simple, yet their consistent application can prevent many foodborne illnesses worldwide. Food Safety Across the Supply Chain Farmers and Producers: Food safety starts at the source. Good Agricultural Practices (GAPs), pesticide management, clean water for irrigation, and animal health monitoring all contribute to the production of safe food and livestock. Processors and Manufacturers: The food industry must implement Hazard Analysis and Critical Control Point (HACCP) systems to identify potential risks and take preventative measures. Distributors and Retailers: Maintaining a cold chain, proper labeling, and ensuring hygiene in storage areas are essential for preserving food safety. Consumers: From washing produce to storing leftovers properly, individuals have a role to play. World Food Safety Day serves as a call to action for all to be informed and vigilant. Food Safety and the Sustainable Development Goals Food safety intersects directly with several Sustainable Development Goals (SDGs): SDG 2: Zero Hunger – Access to safe food is a key component of food security. SDG 3: Good Health and Well-being – Reducing foodborne illnesses contributes to better public health. SDG 12: Responsible Consumption and Production – Promotes sustainable food practices across the supply chain. SDG 17: Partnerships for the Goals – Achieving food safety requires cooperation among nations, sectors, and communities. Without safe food, no country can achieve food security or improved nutrition, essential pillars of sustainable development. Innovations in Food Safety As the world grapples with new challenges, technology is playing an increasingly pivotal role in enhancing food safety: Blockchain allows transparent tracking of food items from origin to shelf, enabling faster recalls when issues arise. Artificial Intelligence (AI) and machine learning help predict contamination patterns and optimize inspection processes. Biosensors and innovative packaging provide real-time monitoring of spoilage or bacterial presence. Drones and satellite imaging help monitor agricultural practices and ensure water safety. These innovations, while not a substitute for regulation or training, offer exciting tools to augment our food safety systems. Shared Responsibility: A Call to Action World Food Safety Day is not merely symbolic—it is a call to action for all stakeholders. Governments must enact and enforce science-based regulations. Industries must prioritize safety, transparency, and training. Academic institutions should lead research and develop safer production methods. Media must communicate risks and best practices effectively. Consumers must stay informed and take individual responsibility. As Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, once noted: 'There is no food security without food safety.' Conclusion In a world of over 8 billion people, food safety might seem like an invisible issue—until it fails. A single lapse can lead to widespread illness, economic damage, and even loss of life. But when it works, food safety quietly supports health, trade, development, and peace. World Food Safety Day serves as a reminder that vigilance, preparedness, and cooperation are essential. Whether you're a policymaker in a capital city, a farmer in a rural village, or a parent preparing dinner, your actions matter. Safe food saves lives, and it starts with each of us. Let us mark this year's World Food Safety Day by renewing our commitment to protecting the world's food supply—for today, and for generations to come.
