SDG 3 emphasizes the importance of ensuring healthy lives and promoting well-being for everyone, which includes access to affordable healthcare. Many people around the world still struggle to get basic health services due to high costs or lack of availability. Making healthcare accessible means not only lowering costs but also improving infrastructure and training more healthcare professionals. This can lead to early diagnosis and better treatment of diseases, ultimately saving lives. When communities have access to affordable healthcare, it boosts productivity and enhances overall quality of life. Healthy populations are essential for thriving societies and sustainable development.
