How do fine haze particles impact the lungs and heart?

Question

Accepted Answer

Fine Haze Particles Pose Significant Risks to Respiratory and Cardiovascular Health

Fine particles present in haze can penetrate deeply into the lungs, leading to inflammation and symptoms such as shortness of breath. Their presence also elevates the risk of experiencing heart attacks and acute cardiac events, as well as increasing the likelihood of hospitalisation.
Respiratory Inflammation and Shortness of Breath

The microscopic nature of fine particles allows them to bypass the body's natural defence mechanisms and reach the deepest parts of the lungs. Once there, they can trigger an inflammatory response, which can manifest as discomfort and difficulty in breathing. This inflammation is a direct consequence of the lungs' reaction to these foreign irritants.
Increased Risk of Cardiac Events

Beyond the respiratory system, fine haze particles have been linked to a heightened risk of cardiovascular problems. Exposure can precipitate heart attacks and acute cardiac episodes, suggesting a systemic impact that extends beyond the lungs. This underscores the interconnectedness of respiratory and cardiovascular health when facing air pollution.
Elevated Hospitalisation Rates

The cumulative effect of these respiratory and cardiac stresses can lead to an increased need for medical intervention. Consequently, the presence of fine particles in haze is associated with a greater likelihood of individuals requiring hospitalisation. This indicates that the health impacts can be severe enough to necessitate professional medical care.
