Health Hazards of PM2.5
PM2.5 refers to airborne particles no larger than 2.5 microns, which can easily penetrate the respiratory system and impact health both in the short and long term. When PM2.5 levels are high, exposure can lead to serious health issues:
- Respiratory problems
PM2.5 can reach deep into the lungs and airways, causing coughing, difficulty breathing, or even chronic lung diseases such as asthma or chronic obstructive pulmonary disease (COPD). - Cardiovascular conditions
Inhaling PM2.5 increases the risk of heart and blood vessel diseases – like hypertension and stroke—because the particles can trigger inflammation in the body. - Impact on children and the elderly
Children and seniors are especially vulnerable to PM2.5, as their respiratory systems are more delicate, making them prone to allergies and respiratory illnesses. - Increased risk of lung cancer
Long-term exposure to PM2.5 can elevate the risk of lung cancer, since toxic substances in the particles can damage lung cells. - Mental health effects
PM2.5 not only affects physical health but can also contribute to stress and anxiety about one’s well-being.
Summary: PM2.5 is highly hazardous—particularly over the long term. Regularly monitoring air quality and taking protective measures against fine dust are essential to reduce health risks.
