Definition of Health

• Behavioral Factors: Lifestyle choices such as diet, physical activity, smoking, and alcohol consumption.
• Social Determinants: Socioeconomic status, education, employment, social support, and cultural practices.
• Environmental Factors: Living conditions, access to clean water and sanitation, exposure to pollutants, and climate.
• Healthcare Services: Availability, accessibility, affordability, and quality of healthcare services.
• Policy and Governance: Public health policies, healthcare infrastructure, and political commitment to health.

Key Health Challenges
