The Hidden Danger You Shouldn't Ignore: "PM2.5 Dust"

How does PM2.5 affect your health? There are many types of airborne particles, such as:

PM10: Particles larger than 10 microns. These are usually trapped in the nasal cavity or mouth and cannot penetrate deeper into our respiratory system.

However, “PM2.5” (fine particulate matter smaller than 2.5 microns) is so tiny that it bypasses nasal hair and the throat, traveling through the large airways and settling deep into the alveoli (air sacs) and lungs. From there, it can even enter the bloodstream, posing a serious threat to multiple organs.

Symptoms to Watch Out For

• Coughing, sneezing, or a runny nose
• Sore throat and excessive phlegm
• Eye irritation or redness
• Difficulty breathing
• Chest tightness

Long-term Health Impact

• Chronic respiratory diseases
• Pharyngitis and frequent infections
• Heart disease
• Lung cancer

How to Protect Yourself from PM2.5

1. Wear a proper face mask: Use an N95 mask or a mask specifically rated to filter PM2.5.
2. Stay indoors: Avoid outdoor areas, especially in high-risk or high-pollution zones.
3. Suspend outdoor activities: Avoid exercising outdoors when dust levels are high.
4. Stay hydrated: Drink plenty of clean water to help your body flush out toxins and maintain oxygen levels.
5. Avoid volatile organic compounds (VOCs): Stay away from smoke from burning trash, paint fumes, traffic exhaust, and industrial pollution.

Seek medical attention immediately if you experience:

• Severe difficulty breathing or shortness of breath
• Extreme eye irritation or burning sensations
• A persistent runny nose lasting more than 1 week
• Chronic coughing or sneezing for more than 2 weeks
