• Physical inactivity
• Tobacco use
• Excessive alcohol
• Chronic stress
• Insufficient sleep

Common Conditions

• Cardiovascular disease (CAD, stroke)
• Type 2 diabetes
• Obesity
• Certain cancers (lung, colorectal)
• Metabolic syndrome
• Chronic kidney disease
• Liver cirrhosis
• Osteoporosis
• Depression and anxiety disorders

Prevention Pillars

• Balanced diet: fruits, vegetables, whole grains, lean protein.
• ≥150 min/week moderate aerobic activity + muscle‑strengthening.
• Tobacco cessation.
• Alcohol moderation or abstinence.
• Stress reduction: mindfulness, CBT, adequate leisure.
• 7–9 hours sleep/night.
• Regular screenings (BP, lipids, glucose, cancer).

Sustained behavioral change reduces incidence, delays onset, and improves quality of life.
