You're referring to a landmark 2018 study published in the journal Circulation by Li et al., affiliated with Harvard T.H. Chan School of Public Health. This study indeed followed over 120,000 adults (specifically 78,865 women from the Nurses' Health Study and 44,354 men from the Health Professionals Follow-up Study) for 34 years, assessing how lifestyle habits impacted longevity.
🔑 Key Findings:
People who consistently practiced 5 specific low-risk lifestyle habits were:
-
74% less likely to die during the study period.
-
Had up to 14 additional years of life compared to those who followed none of the habits.
✅ The 5 Daily Habits:
-
Healthy Diet – High in fruits, vegetables, whole grains, healthy fats; low in red/processed meats and sugar.
-
Regular Physical Activity – At least 30 minutes per day of moderate to vigorous activity.
-
Healthy Body Weight – BMI between 18.5–24.9.
-
Not Smoking – Never smoked or had quit for good.
-
Moderate Alcohol Intake – Up to 1 drink/day for women and 2 for men.
🧠 Why This Matters:
These are modifiable behaviors, meaning you can control them. Unlike genetics or certain environmental factors, these five habits are daily decisions that dramatically reduce your risk for chronic diseases like heart disease, cancer, and type 2 diabetes, all leading causes of premature death.
