Why is air pollution harmful to health?

Air pollution, especially fine particles called PM2.5, can enter deep into the lungs and bloodstream. Long-term exposure increases the risk of asthma, COPD, heart attacks, strokes, lung cancer and premature death. It also affects children’s lung development.

On high-pollution days:

• Check the AQI and limit outdoor activity when it is poor or severe.
• Use a well-fitted N95 mask outdoors if needed.
• Keep windows closed during peak pollution hours and consider an air purifier at home.
• Avoid exercising near busy roads.

People with asthma, heart disease, the elderly and children should take extra care. More in nature and environment.
