The primary health concern is the presence of PM2.5 particles in the smoke, which are small enough to penetrate deep into the lungs and enter the bloodstream. These particles can cause symptoms such as coughing, irritated eyes, shortness of breath, and headaches. Individuals with pre-existing conditions like asthma, heart disease, or COPD are at higher risk. The combination of poor air quality and high temperatures poses additional risks, particularly for outdoor workers, children, and the elderly. Residents are advised to take precautions to minimize exposure to the polluted air.
