We advice to monitor the air quality for people who want to go (especially exercise ) outdoor in winter time . 

When considering outdoor exercise and PM2.5 levels, it's important to balance the health benefits of physical activity with the potential risks posed by air pollution. Here are some general recommendations based on PM2.5 levels:

1. Good (0-12 µg/m³):

   • Air Quality: Excellent

   • Recommendation: Ideal for outdoor exercise. No restrictions.

2. Moderate (12-35 µg/m³):

   • Air Quality: Acceptable

   • Recommendation: Generally safe for most people. Those who are unusually sensitive to air pollution should consider reducing prolonged or heavy exertion.

3. Unhealthy for Sensitive Groups (35-55 µg/m³):

   • Air Quality: May cause health issues for sensitive individuals (e.g., people with asthma, heart disease, or respiratory conditions).

   • Recommendation: Sensitive groups should reduce prolonged or heavy outdoor exertion. Healthy individuals can usually continue outdoor activities but should monitor for symptoms like coughing or shortness of breath.

4. Unhealthy (55-150 µg/m³):

   • Air Quality: Everyone may begin to experience health effects.

   • Recommendation: Limit prolonged or heavy exertion outdoors. Sensitive groups should avoid outdoor exercise. Consider indoor activities instead.

5. Very Unhealthy (150-250 µg/m³):

   • Air Quality: Health warnings of emergency conditions.

   • Recommendation: Avoid outdoor exercise. Everyone, especially sensitive groups, should stay indoors and keep activity levels low.

6. Hazardous (250+ µg/m³):

   • Air Quality: Health alert: everyone may experience more serious health effects.

   • Recommendation: Stay indoors and avoid all physical activity outdoors.

Additional Tips:

• Check Air Quality Index (AQI): Use reliable sources like AirNow, iqair , airvisual ,local environmental agencies, or apps to monitor real-time PM2.5 levels.

• Time of Day: Air quality can vary throughout the day. Early morning or late evening might have lower PM2.5 levels.

• Location: Avoid exercising near high-traffic areas or industrial zones where pollution levels are typically higher.

• Mask: In areas with moderate to high PM2.5 levels, consider wearing a mask designed to filter out fine particles if you must exercise outdoors.
