In recent months, smog has become a recurring problem, making PM2.5 a major concern for public health. As air pollution continues to rise, people are increasingly worried about its impact on their bodies. What are the health risks associated with smog? Which diseases can it trigger? And what can ordinary citizens do to protect themselves? To address these pressing questions, our reporter spoke with experts in environmental and medical fields.
According to the experts, prolonged exposure to smog can significantly increase the risk of respiratory diseases, including lung cancer. While there is currently no concrete statistical data in China linking outdoor air pollution directly to lung cancer, international studies have shown a clear correlation. Experts strongly advise people to limit outdoor activities when smog levels are high. It's best to avoid crowded indoor spaces, as poor ventilation can worsen air quality. Wearing an N95 mask can offer some protection, but it should not be worn for extended periods. Prolonged use may affect breathing efficiency and cause discomfort in the chest. Additionally, maintaining good indoor air circulation by opening windows whenever possible is highly recommended.
In addition to these measures, experts also suggest staying informed about local air quality reports and adjusting daily routines accordingly. For those with pre-existing conditions such as asthma or chronic obstructive pulmonary disease (COPD), extra caution is necessary. A balanced diet, regular exercise, and proper hydration can also help strengthen the body’s defenses against pollution-related illnesses.
As awareness grows, more individuals are taking proactive steps to safeguard their health. Whether through personal protective equipment, lifestyle changes, or policy advocacy, the fight against smog is becoming a shared responsibility.
