Long-term exposure to air pollution harms cardiovascular health, causing inflammation and increasing the risk of heart disease.
Long-term exposure to air pollution can significantly impair quality of life, primarily affecting the respiratory and cardiovascular systems. “The interplay between air pollution and health outcomes is diverse and complex and involves multiple exposure pathways that can lead to the development of cardiovascular disease (CVD). “Air pollution is a well-known risk factor for CVD morbidity and mortality, second only to hypertension, dietary exposure and smoking,” Dr. Says Naresh Kumar Goyal, Senior Director and HOD Cardiology, Fortis Hospital, Shalimar Bagh, Delhi.
Some facts about air pollution
- It is the cause of one in eight deaths globally.
- This led to 8.1 million deaths in 2021.
- Currently this reduces the average person’s life span by one year and eight months.
Air pollution, which affects our health in many ways, is now increasingly linked to heart diseases. Long-term exposure to airborne pollutants can cause inflammation and oxidative stress in the circulatory system, increasing the risk of cardiovascular diseases. Poor quality air can deliver pollutants deep into the bloodstream through the lungs, increasing the likelihood of heart and circulatory problems. These pollutants can narrow and harden blood vessels, hindering blood flow and potentially increasing blood pressure. Additionally, they can disrupt the heart’s electrical system, leading to abnormal rhythms, and even the structural changes seen in early-stage heart failure. For individuals with existing heart disease, the damage may increase the risk of heart attack or stroke.
Long-term exposure to air pollution can significantly impair quality of life, primarily affecting the respiratory and cardiovascular systems, although other physiological systems may also be adversely affected. Irregular oxygen supply increases the risk of cardiovascular diseases.
Mitigation Strategies
- Staying informed about the air quality in your area can help individuals reduce exposure on days when pollution levels are high.
- On days with poor air quality, it is advisable to reduce outdoor activities, especially strenuous exercise. Choose indoor options when possible.
- Using air purifiers and ensuring proper ventilation can help reduce indoor air pollution.
- Supporting policies aimed at reducing air pollution can lead to long-term improvements.
- Regular medical checkups are essential for people at risk of heart failure.
