What are the main components of a healthy lifestyle that nurses should teach for disease prevention?

Comprehensive lifestyle teaching addresses major modifiable risk factors for chronic disease. (1) Nutrition: balanced diet emphasizing fruits, vegetables, whole grains, lean protein, healthy fats; limit added sugars, refined carbs, sodium, saturated/trans fats; Mediterranean or DASH diets show strong evidence; portion control. (2) Physical activity: WHO/CDC recommend at least 150 minutes moderate-intensity OR 75 minutes vigorous-intensity aerobic activity per week, PLUS muscle-strengthening 2+ days/week. Any activity beats sedentary; sitting >8 hours daily is a risk factor. (3) Tobacco: avoid all forms (cigarettes, vaping, smokeless tobacco, secondhand smoke); cessation counseling and pharmacotherapy when ready; tobacco causes major morbidity and mortality. (4) Alcohol: limit to ≤1 drink/day for women, ≤2 for men (or less); abstinence preferred during pregnancy and for some medical conditions; no safe level for cancer risk. (5) Sleep: 7-9 hours/night for adults; sleep hygiene practices; address sleep apnea and insomnia. (6) Stress management: mindfulness, exercise, social connection, hobbies, therapy when needed. (7) Social connections: strong social relationships reduce all-cause mortality. (8) Preventive care: annual physical (or every 1-3 years per age), screenings, immunizations, dental care. (9) Sun protection: sunscreen, protective clothing, shade. (10) Safety: seatbelts, helmets, fall prevention, gun safety. These factors prevent leading causes of death: heart disease, cancer, stroke, COPD, diabetes complications, accidents.
