On World Heart Day 2023, Ajay Pandey, an Interventional Cardiologist at Bhatia Hospital, Mumbai talks about the heart-environment connection
In a world where global health concerns take center stage, World Heart Day emerges as a beacon of hope. Beyond advocating for cardiovascular well-being, it also champions sustainability within healthcare systems. Established by the World Heart Federation in 2000, this annual observance on September 29th emphasises the importance of heart health and the adoption of sustainable healthcare practices. Recent years have highlighted the vital connection between environmental sustainability and overall well-being, emphasising the urgency of addressing environmental factors affecting heart health and the healthcare system as a whole.
The heart-environment connection
The environment wields substantial influence over not only the well-being of our hearts but also our overall health.
Air quality: Poor air quality, often caused by industrial emissions and vehicle exhaust, is a major contributor to heart disease. Particulate matter and pollutants can lead to inflammation and oxidative stress, increasing the risk of heart attacks and strokes.
Climate change: Alterations in the climate have diverse repercussions on heart health. For example, extreme heat can exacerbate cardiovascular conditions, and a warmer world with an increased prevalence of infectious diseases can indirectly affect heart health. Furthermore, climate change can contribute to shortages of food and water, which in turn influence dietary choices and nutrition, crucial factors in maintaining heart health.
Access to green spaces: Lack of access to green spaces and opportunities for physical activity can contribute to sedentary lifestyles, obesity, and related heart problems. Green spaces provide an opportunity for exercise, relaxation, and stress reduction, all of which are essential for maintaining a healthy heart.
Food production and sustainability: The way we produce, distribute, and consume food has profound implications for both heart health and the environment. Unsustainable agricultural practices, including excessive meat consumption and deforestation, contribute to climate change and may lead to heart-unhealthy diets.
Promoting sustainable healthcare on World Heart Day
Recognising the interconnectedness of heart health and environmental sustainability, World Heart Day has increasingly shifted its focus towards promoting sustainable healthcare practices. Here are some key ways in which the event addresses this critical issue:
Awareness and education: World Heart Day functions as an educational platform, elevating consciousness regarding the environmental elements that influence heart health. By imparting knowledge to the public regarding the significance of fresh air, sustainable dietary practices, and the advantages of green spaces, the occasion motivates individuals to embrace eco-conscious decisions that promote their well-being and contribute to the planet’s welfare.
Research and innovation: World Heart Day also highlights the role of research and innovation in sustainable healthcare. It encourages investment in research that explores the links between environmental factors and heart health, as well as the development of sustainable healthcare technologies and practices.
Community engagement: Many World Heart Day events and initiatives involve local communities. Activities such as tree planting, community clean-up drives, and outdoor fitness programs not only promote cardiovascular health but also foster a sense of environmental stewardship.
Partnerships and collaboration: Collaboration between healthcare providers, environmental organizations, and policymakers is crucial for addressing the complex challenges at the intersection of heart health and environmental sustainability. World Heart Day serves as a catalyst for forging such partnerships.
The imperative of sustainable healthcare
Sustainable healthcare practices have evolved from being a choice to becoming an indispensable necessity for protecting the health and well-being of both current and future generations.
Healthcare’s carbon footprint reduction: Healthcare facilities, through energy-intensive medical equipment and hazardous waste management, significantly contribute to carbon emissions. Sustainable healthcare aims to shrink this environmental footprint by embracing energy-efficient technologies, waste reduction, and eco-friendly practices.
Resilience to climate change: Climate change poses a direct threat to healthcare systems. Increasingly frequent extreme weather events can disrupt healthcare delivery, damage infrastructure, and overwhelm hospitals. Sustainable healthcare includes measures to adapt to these challenges and ensure that critical healthcare services remain accessible during crises.
Health equity: Sustainable healthcare practices also promote health equity. Vulnerable populations are often disproportionately affected by both environmental degradation and health disparities. Addressing these issues together can help reduce health inequities and ensure that everyone has access to quality healthcare and a clean environment.
Cost savings: Sustainability in healthcare is not just about protecting the environment; it’s also about improving the bottom line. By reducing waste, energy consumption, and the need for expensive interventions, sustainable healthcare can lead to cost savings that benefit both healthcare providers and patients.
World Heart Day highlights the distinct influences of urban and rural lifestyles on cardiovascular health. Urban areas offer advanced healthcare and education but expose individuals to pollution and sedentary habits. In contrast, rural living connects people to nature but can present healthcare and education challenges. This day urges customised heart health strategies for these diverse lifestyles and their environmental factors, advancing a healthier, more sustainable future.
Recognising the link between pesticide exposure and cardiovascular health is essential, as residues in our food may harm our hearts. Supporting sustainable agriculture and reducing pesticide use can lead to healthier diets and eco-friendly food production. Kitchen upkeep matters for heart health and sustainability, as well-maintained spaces encourage better cooking practices and less food waste. Additionally, meal timing is crucial, with late-night snacking potentially negatively affecting heart health. On this World Heart Day, let’s reflect on our dietary choices, their environmental impact, and meal timings for improved cardiovascular well-being and sustainability.
World Heart Day’s growing emphasis on environmental sustainability underscores the undeniable connection between our cardiac well-being and the planet’s health. Through awareness, policy advocacy, research support, community engagement, and collaborative efforts, World Heart Day becomes a pivotal force driving sustainable healthcare. It serves as a powerful reminder that safeguarding our hearts and environment are intertwined, and our present choices will mold the well-being of future generations.
