Abstract : This study investigates the influence of healthy lifestyle practices on life expectancy by focusing on three highly populated countries: China, Japan, and India. It delves into key factors such as dietary patterns, levels of physical activity, healthcare infrastructure, environmental conditions, and cultural traditions that play a vital role in shaping the overall health and longevity of their populations. By analysing these aspects, the research highlights both the shared and unique contributors to life expectancy within these nations. The findings aim to provide a deeper understanding of how different health policies and lifestyle behaviours interact within distinct social and economic frameworks, ultimately offering guidance on strategies that could improve longevity and well-being across diverse populations.

Keywords : Life Expectancy, Healthy Living, Comparative Analysis, China, Japan, India, Healthcare Systems, Lifestyle Habits, Nutrition, Physical Activity, Environmental Factors.
