what are effects of air pollution on humans?

Air pollution can indeed have various effects on human health, and it sounds like what you’re experiencing may be related. The most immediate effects of poor air quality are often seen in the respiratory system. You mentioned coughing and a scratchy throat; these could be initial signs of your body reacting to pollutants in the air, such as particulate matter (PM), nitrogen dioxide (NO2), and ozone, which are known to irritate the airways. For children, like your sister, who are still developing, the respiratory effects can sometimes be more pronounced, leading to increased sneezing or even exacerbating asthma symptoms if she has a history of asthma. Beyond this, exposure to air pollution has been linked to cardiovascular issues as well. Pollutants can contribute to inflammation and oxidative stress in the body, potentially affecting heart health, with longer-term exposure possibly increasing the risk of conditions like hypertension and heart disease. Feeling dizzy or lightheaded after being outdoors is another possible symptom of air pollution exposure. This might be due to low levels of oxygen in the polluted air or other factors like carbon monoxide, which can interfere with oxygen delivery to the body. It’s also worth mentioning that some people are more sensitive to these effects than others, depending on pre-existing health conditions or other risk factors. Chronic exposure to high pollution levels can have long-lasting effects, potentially leading to chronic respiratory diseases like COPD or lung cancer over years of exposure. To mitigate these effects, consider monitoring local air quality reports and reducing outdoor activities when pollution levels are high. Using air purifiers indoors, keeping windows closed on days with poor air quality, and wearing masks specifically rated for filtering fine particles can also help reduce exposure. Of course, it’s important to talk to a healthcare professional about any persistent symptoms you’re experiencing to rule out any other underlying conditions and to receive personalized advice based on your specific health and lifestyle needs.
