Can Feeding Pigeons Regularly Harm Your Lungs? Tips To Protect Yourself
Last Updated:
Delhi's Sir Ganga Ram Hospital has found a strong link between prolonged exposure to pigeons and serious lung diseases.
If there is one bird that has dominated the urban landscape in recent years, it's pigeons. City squares, roadside patches, and community spaces have transformed into pigeon feeding grounds, leading to a population explosion. While feeding these birds is seen as an act of compassion, many people are unaware that pigeons pose serious health risks.
Pigeons leave behind a trail of feathers and droppings, which causes real harm. These can carry fungal, bacterial, and parasitic infections, which may trigger allergic reactions, and even lead to serious lung diseases. According to research by Delhi's Sir Ganga Ram Hospital, prolonged exposure to pigeons can have severe health consequences. Studies have also linked frequent feeding and proximity to these birds to increased health risks.
Health Risks Of Pigeon Feeding
Pigeon droppings may appear innocuous, but they can harbour harmful fungi like Aspergillus. When inhaled, these fungi can cause Histoplasmosis, leading to serious lung conditions such as Bird Breeder's Lung (Hypersensitivity Pneumonitis). This may trigger an immune response, causing inflammation in the lungs' interstitium, which is crucial for oxygen exchange.
If left untreated or diagnosed late, Hypersensitivity Pneumonitis can progress to irreversible lung fibrosis, severely impairing respiratory function. However, early detection within six weeks of symptom onset can often reverse the condition with treatment. It's essential to be aware of the risks associated with pigeon droppings to prevent long-term damage.
How To Protect Yourself?
You can also follow these steps to eliminate potential risks.
Use Deterrents Like Tape: Spike strips, reflective tape, or ultrasonic repellents can prevent pigeons from roosting.
Disinfect Regularly: Clean surfaces with bleach or strong disinfectants to eliminate pigeon droppings and bacteria.
Check Hidden Areas: Check building ducts, water tanks, and other hidden spots for pigeon nests and seal any openings.

Climate change may fuel spread of fungi that could 'eat you from inside out'
As Covid-19 cases begin to rise again in parts of the world, including India, there's another silent but serious health threat emerging, this time from the fungal kingdom. The rising global temperatures could accelerate the fungi capable of eating you from inside out. A new climate modelling study by researchers at the University of Manchester shows that rising temperatures could dramatically alter the spread of Aspergillus, a group of airborne fungi known to cause severe respiratory infections in humans and widespread damage to crops. Published on the preprint platform Research Square, the study titled Climate change-driven geographical shifts in Aspergillus species habitat and the implications forplant and human health maps how the geographical range of three major Aspergillus species could expand significantly by year 2100, exposing millions more people to the risk of infection, especially across Europe and Asia. Why are Aspergillus fungi a growing concern? The Aspergillus genus includes several common environmental fungi found in soil, compost, and air. While generally harmless to healthy people, they can cause aspergillosis, a serious respiratory infection, in those with weakened immune systems. These fungi are also notorious for spoiling crops and producing dangerous mycotoxins. But here's the real problem — they're evolving. Rising global temperatures and widespread use of agricultural fungicides are helping these pathogens become more heat-tolerant and resistant to antifungal drugs, leaving doctors with fewer tools to treat infections. How rising temperatures increase fungal risks Using global climate models and species distribution tools, the University of Manchester team simulated how suitable habitats for Aspergillus fungi will shift under three scenarios, including low, intermediate, and high warming. Impact in a low warming scenario (below 2°C): Minimal changes in habitat range for Aspergillus species, and the spread is relatively contained. Impact in intermediate warming (2.5–3°C by 2100): Noticeable spread of fungal pathogens into new regions, especially in the Northern Hemisphere. Impact in high warming (around 4°C by 2100): Significant and rapid expansion of Aspergillus habitats, particularly A. flavus and A. fumigatus, into Europe, North Asia, and North America, putting millions at increased risk. ALSO READ | Why scientists are especially alarmed by these findings Antifungal resistance: A. flavus, in particular, is already resistant to many existing treatments. Lack of medical tools: There are no vaccines, diagnostics are limited, and antifungal options are few. Dr Norman van Rhijn, lead author of the study, explains in a statement, 'We've already seen the emergence of Candida auris due to rising temperatures, but this is just the beginning. These maps show how fungal pathogens will likely impact most areas of the world in the future. Raising awareness and developing effective interventions is essential.' Fungi are shifting toward the Northern Hemisphere According to the study, the biggest changes will happen in the Northern Hemisphere. Europe and North Asia: Projected to see the largest increase in fungal suitability due to milder climates becoming warmer. Africa and South America: Paradoxically, these regions could become too hot for fungi like A. flavus to survive — threatening ecosystems that rely on fungi to decompose organic matter and regulate the carbon cycle. The study shows a striking poleward shift: fungi are moving north, where millions more people could be exposed. Climate change threatens food security via fungal spread The study highlights that A. flavus and A. niger are major crop pathogens, especially for maize, rice, and grapes. The research warns of: Reduced habitat suitability in current crop-growing zones Increased risk of contamination in new areas Food insecurity due to loss and spoilage of yields Antifungal resistance is also being driven by overuse of fungicides in agriculture, which compromises both plant and human health. Why fungal threats are difficult to fight Unlike bacteria, fungi are biologically closer to humans, meaning antifungal drugs often have toxic side effects. Plus, only a tiny fraction of the estimated 1.5 to 3.8 million fungal species have been studied, and less than 10 per cent have been sequenced genetically. How to prepare for a warming-driven fungal threat According to the study and public health experts: Accelerate climate action to limit warming and slow fungal spread Invest in fungal diagnostics, surveillance, and treatments Improve awareness among healthcare workers and the public Develop sustainable farming practices to reduce fungicide-driven resistance Fungi may not make daily headlines like viruses do, but they are quietly becoming one of the most dangerous climate-driven health threats of our time. As global warming accelerates their spread and evolution, ignoring them is no longer an option. For more health updates, follow #HealthWithBS

What is Aspergillus? The deadly fungus spreading rapidly and can eat humans 'inside out'
An increase in global temperatures might result in the Aspergillus fungus that causes many annual deaths affecting greater areas, the new research reveals. Many types of Aspergillus spread in the world and can infect people, pets and plants, as scientists at Manchester University explain. According to both The Lancet and CNN, the study is being reviewed at present by a group of international experts. What is Aspergillus? In many parts of the globe, Aspergillus is recognised as a common group of fungi. It causes aspergillosis, which can be fatal, and primarily affect the lungs. Researchers used several types of modelling and forecasting techniques to track where Aspergillus would spread in the future. As part of the research, scientists found that there were specific Aspergillus species that will expand in the future as the climate crisis intensifies. These species will expand into new parts of Canada, the U.S., Europe, China, and Russia. In comparison, viruses and parasites have received more attention from researchers than fungi, says Norman Van Rijn, one of the authors of the study. He predicts these are expected to impact the major areas of the world. Why is this infection so deadly and who is at risk? An estimated figure is that fungal infections every year claim the lives of more than 2.5 million individuals. It's possible the number is even higher since not all data is available. As with many fungi, Aspergillus appears in soils as tiny filamentous structures. Subsequently, they create many spores that travel with the air. Every day, humans take in these air pollutants. Usually, most people do not have any issues with their health because their immune system can deal with most threats. That's different for individuals suffering from asthma, cystic fibrosis or COPD. Patients who have had cancer or organ transplants are high at risk due to weakened immune system. According to Van Rijn, if your immune system can't get rid of the spores, the fungus begins to grow. 'The fungus starts to grow and basically kind of eat you from the inside out, saying it really bluntly,' van Rijn said. Aspergillus flavus, which favours hot and tropical places, could see its range grow by 16% if we keep relying on fossil fuels, according to the study. Candida species can cause really serious infections and are still resistant to some drugs. For this reason, the infection can spread among a wide range of food crops, making it a serious problem for food security too.
