A recent report highlights a serious global issue: most cities have polluted air, with only 17% meeting the World Health Organization’s (WHO) air quality guidelines. This alarming finding comes from IQAir, a platform that monitors air quality worldwide. Their analysis of data from 40,000 stations across 138 countries pinpointed Chad, Congo, Bangladesh, Pakistan, and India as the most polluted places.
Experts warn the real pollution levels could be even worse. Many areas lack comprehensive monitoring, leaving large gaps in data.
Air pollution doesn’t just impact the environment; it significantly affects our health too. Here’s a closer look at how it can harm different parts of our bodies.
Lungs
Air pollution can inflame and irritate the airways, causing coughs, difficulty breathing, and other serious lung issues. Jonathan Blades from Asthma + Lung UK notes that children’s lungs are particularly at risk. Pollutants can enter deeply into their lungs and stunt growth, leading to long-term problems like asthma or chronic obstructive pulmonary disease (COPD) later in life.
If you’re living in a polluted area, it’s wise to check the local pollution levels and plan outdoor activities when air quality is better.
Heart
Pollutants, such as fine particles and nitrogen dioxide, can contribute to inflammation in the body, making blood vessels stiffer. According to Dr. Oliver Guttmann, a consultant cardiologist, this can raise blood pressure and strain the heart, increasing the chances of heart disease or strokes. If you have a heart condition, elevated pollution levels can worsen symptoms. Maintaining a healthy diet and managing stress can help protect your heart.
Skin
Dr. Ross Perry, a medical director at Cosmedics, explains that pollution can weaken the skin’s natural barriers. This damage can lead to dehydration, dull skin, and accelerated aging over time. To combat these effects, he suggests a consistent cleansing routine and moisturizing with ingredients that hydrate and protect the skin.
Brain
Pollution can also impact brain health. Dr. Steven Allder, a neurologist, mentions that pollutants can disrupt neural connections, impairing memory and decision-making. There’s also a worrying link between pollution and mental health, with higher rates of anxiety and depression observed in areas with worse air quality. Using air purifiers and wearing masks in polluted areas can help.
Eyes
Francesca Marchetti, an optometrist, points out that pollution affects our eyes, leading to redness and itchiness due to allergic reactions. She advises people to address these symptoms without delay, suggesting that minor issues should be treated promptly at a pharmacy.
In summary, air pollution is a major health threat affecting multiple aspects of our well-being. Each of us can take steps to protect our health by being aware of our environment and making informed choices. For those interested in tracking air quality, resources such as the WHO or local environmental agencies can provide valuable guidance.
