Extreme AQI: How Toxic Air Harms Your Body
9 Nov
Summary
- Polluted air over AQI 400 poses severe health risks.
- PM2.5 particles penetrate lungs and enter bloodstream.
- Vulnerable groups face higher risks from toxic pollutants.
Air pollution levels exceeding an AQI of 400 present significant health hazards. Prolonged exposure to fine particulate matter, especially PM2.5, can deeply infiltrate the lungs and even enter the bloodstream. This triggers inflammation and oxidative stress throughout the body.
These effects extend beyond respiratory issues, potentially impairing lung function and elevating cardiovascular risks. Immediate symptoms may include coughing and breathlessness, but long-term exposure can lead to serious complications affecting the heart and blood vessels.
Certain populations, including older adults and those with pre-existing conditions like asthma, diabetes, and hypertension, are more susceptible. Their bodies may be less equipped to combat the inflammatory responses and stress induced by toxic air.
When AQI levels are critically high, it is advised to minimize outdoor activities. If venturing outside is necessary, wearing an N95 or FFP2 mask is recommended. Maintaining good indoor air quality by closing windows and using air purifiers also helps reduce exposure to harmful pollutants.
