Poor air quality index (AQI) has a significant impact on our health. When the AQI is high, it means that the air is polluted with harmful substances such as particulate matter, ozone, carbon monoxide, and nitrogen dioxide. Breathing in such polluted air can lead to various health problems. Short-term exposure to poor AQI can cause irritation in the eyes, nose, and throat, as well as respiratory issues like coughing and wheezing. Prolonged exposure to polluted air can increase the risk of developing respiratory diseases, such as asthma, bronchitis, and even lung cancer. Additionally, poor AQI can also worsen existing health conditions like allergies and cardiovascular diseases. It is crucial to take necessary precautions and protect ourselves from the harmful effects of poor air quality to maintain good health.
