Maintaining a Healthy Circulatory System: Evidence-Based Lifestyle Pillars

Cardiovascular disease is the leading global cause of death, but 80% of premature events are preventable through lifestyle.

7 Core Pillars

1. Regular Physical Activity: ≥150 min moderate (brisk walk) or ≥75 min vigorous (running) weekly + muscle-strengthening 2×/week. Lowers BP, LDL, improves endothelial function.
2. Heart-Healthy Diet: Mediterranean or DASH pattern: vegetables, fruits, whole grains, legumes, nuts, olive oil, fish; limit red meat, processed foods, added sugar, sodium (<2.3g/day, ideally <1.5g).
3. No Tobacco: Smoking damages endothelium, promotes atherosclerosis, raises BP, increases clotting. Quitting at any age adds years. Avoid vaping.
4. Blood Pressure Control: Target <130/80 mmHg (ACC/AHA). Home monitoring; DASH diet, low Na, exercise, meds if needed.
5. Cholesterol Management: Focus on LDL-C. Statins for primary/secondary prevention per risk calculator (ASCVD). Diet: replace saturated with unsaturated fats.
6. Healthy Sleep: 7–9 hours/night. Short/long sleep and apnea increase CVD risk. Treat sleep apnea.
7. Stress Management: Chronic stress → cortisol, inflammation, poor behaviors. Mindfulness, CBT, social connection, nature.

Additional Protective Factors

• Moderate alcohol (if at all): ≤1 drink/day women, ≤2 men.
• Weight management (BMI 18.5–24.9; waist <40" M, <35" F).
• Regular check-ups: BP, lipids, glucose, ASCVD risk score.
• Vaccinations (flu, COVID, pneumococcal) — infections trigger cardiac events.
