Healthspan, healthy ageing, and chronic disease are pivotal topics in today’s health discourse, emphasizing not just the length of life but the quality of those additional years. Focusing on healthspan means striving for a longer period of life free from disease and disability, which is increasingly important as global life expectancies rise. Healthy ageing involves adopting lifestyle habits that promote physical, mental, and social well-being throughout the lifespan, thereby reducing the risk of chronic diseases such as heart disease, diabetes, and neurodegenerative disorders.

Addressing chronic diseases risk requires a proactive approach centered on prevention and early intervention. By prioritizing healthspan and healthy ageing, individuals can significantly decrease the likelihood of developing chronic illnesses, leading to improved quality of life and reduced healthcare costs.
