Harmful Health Impacts of 350+ Air Quality Index (AQI) In Delhi Today
NEW DELHI : As air quality levels continue to decline in various regions, surpassing an AQI of 400, it’s critical to understand the potential health risks this extreme level of air pollution poses. A 400+ AQI indicates “hazardous” air, filled with particulate matter, gases, and pollutants that can seriously harm health.
Immediate Health Impacts of Hazardous AQI
-
Respiratory Irritation and Inflammation
High AQI levels can lead to immediate respiratory issues, including irritation of the airways, inflammation, and increased mucus production. This is especially dangerous for those with asthma or other pre-existing respiratory conditions.
-
Reduced Oxygen Levels
Pollutants in hazardous air reduce oxygen flow in the blood, leading to shortness of breath, fatigue, and an increased heart rate. People may feel tired and unable to engage in normal physical activities.
- Chronic Respiratory Diseases
Exposure to high AQI levels over an extended period can contribute to the development of chronic respiratory conditions, such as asthma, bronchitis, and emphysema. Persistent inflammation can lead to irreversible lung damage. - Cardiovascular Disease Risks
Pollutants enter the bloodstream and impact heart health. Long-term exposure is linked to increased risks of heart attacks, arrhythmias, and hypertension. Studies show a direct correlation between air pollution and heart disease severity. - Cancer Risks
Particulate matter (PM2.5 and PM10) contains carcinogenic compounds, increasing the likelihood of lung and other types of cancers over prolonged exposure. Areas with consistently high AQI levels show higher rates of cancer incidence.
- Children and Elderly Individuals
Children’s developing respiratory systems are more susceptible to pollutants, potentially affecting their lung growth and immune system. The elderly, often with weaker immune systems, face higher risks of respiratory and cardiovascular complications. - Pregnant Women
Exposure to high AQI levels can affect fetal development, leading to low birth weight, preterm birth, and developmental delays. Toxic particles can cross the placental barrier, impacting the health of both mother and baby. - Individuals with Pre-Existing Conditions
People with respiratory issues, diabetes, or heart conditions face amplified health risks, as pollutants worsen their conditions, leading to more frequent hospitalizations.
- Cognitive Decline
High AQI levels have been associated with cognitive decline in both adults and children. Studies link air pollution with memory loss, reduced focus, and slower cognitive processing. - Increased Anxiety and Depression
Research suggests a connection between air pollution and mental health. High AQI levels increase stress hormones, contributing to anxiety, depression, and other mental health issues.
- Stay Indoors
Limit outdoor activities during high AQI periods to reduce exposure. Use air purifiers indoors to filter out harmful particles. - Wear Masks and Eye Protection
When outdoors, wear N95 masks that can filter out particulate matter. Eye protection can also prevent irritation from pollutants. - Monitor AQI Levels
Stay informed about daily AQI levels through reliable sources and take precautions accordingly.
