Air pollution, especially PM2.5 toxic dust, has become a significant issue affecting both health and the environment. PM2.5 refers to fine particulate matter that is invisible to the naked eye—25 times smaller than a strand of hair—but it has a profound impact on health. Due to its tiny size, PM2.5 can enter the respiratory system and bloodstream, potentially leading to various health problems such as respiratory diseases, heart conditions, and chronic lung diseases. Therefore, protecting yourself from PM2.5 is crucial and should not be overlooked.

How to Protect Yourself from PM2.5
1. Wear a Dust Protection Mask in High-Risk Areas
In areas with heavy traffic or near industrial zones, it’s important to wear an N95 mask or a mask specifically designed to filter PM2.5 particles. These masks help block fine particulate matter and reduce respiratory risks.
2. Regularly Monitor the Air Quality Index (AQI)
Keeping track of air quality levels in your area or any place you plan to visit is essential. You can use applications like Air4Thai or follow news outlets that report air quality to plan your activities and take precautions against pollution each day.
3. Watch for Unusual Physical Symptoms
If you experience symptoms such as coughing, chest tightness, dizziness, nausea, or any other unusual signs, consult a doctor immediately. This can help prevent worsening conditions or severe health issues. Individuals with chronic illnesses should be especially vigilant for any abnormal symptoms during periods of high PM2.5 levels.
4. Adjust Your Habits to Reduce Risk
Developing habits to protect yourself can significantly lower your exposure to pollution. This includes consistently wearing a mask, keeping doors and windows closed when pollution levels are high, and using air purifiers at home to filter out fine dust particles.
5. Limit Outdoor Activities on High-Pollution Days
When PM2.5 levels reach the orange zone (affecting health) or red zone (dangerous for everyone), outdoor activities should be minimized. Those who enjoy exercising outdoors should switch to indoor workouts instead.
