Health literacy plays a crucial role in promoting sustainable healthcare by addressing social, economic, and environmental dimensions. It empowers individuals to understand and use health information effectively, reducing health disparities and improving health outcomes. Social sustainability is linked to health literacy, as it influences health equity and access to healthcare services. Economic sustainability is enhanced by health literacy, which can reduce healthcare costs through informed decision-making and efficient resource use. Environmental sustainability is supported by health literacy, which helps individuals understand the impact of environmental factors on health and take proactive measures to protect the environment. Integrating health literacy into education and healthcare training is essential for promoting sustainability. However, challenges such as limited awareness and resource constraints hinder progress. Collaboration between academia, healthcare institutions, and communities is vital to overcome these barriers. Health literacy initiatives should be culturally sensitive and tailored to diverse populations. Environmental health literacy, a subset of health literacy, focuses on understanding environmental factors affecting health and taking action to protect the environment. To achieve sustainable healthcare, health literacy must be incorporated into educational curricula and professional training. This includes developing health literacy programs for students and healthcare professionals. Research and policy development are needed to support these efforts. Despite challenges, health literacy has the potential to improve healthcare systems by promoting informed decision-making, reducing healthcare costs, and enhancing environmental sustainability. A multi-sectoral approach involving policy, education, and community engagement is necessary to realize the benefits of health literacy in sustainable healthcare.Health literacy plays a crucial role in promoting sustainable healthcare by addressing social, economic, and environmental dimensions.
