Introduction
In recent decades, advancements in technology and healthcare have significantly increased life expectancy and improved overall health conditions. Yet, reaching the age of 100 remains a remarkable achievement attained by relatively few individuals. When someone reaches this milestone, many are eager to understand the key factors that contribute to such longevity.
Study Findings
According to a study published in the scientific journal JAMA Network Open, certain habits and behaviors can greatly enhance the likelihood of reaching the age of 100 in good health. The study drew data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS), a longitudinal research initiative focusing on the health and lifestyles of elderly Chinese adults, including centenarians.
Key Factors for Longevity
The study identified three primary habits strongly associated with longevity:
1. Non-Smoking
Foremost among the key factors is the absence of smoking. Cigarette smoking is well-known to contribute to various health issues such as heart disease, cancer, and lung diseases, significantly reducing life expectancy.
2. Regular Physical Exercise
Regular physical exercise is another essential factor for longevity. It helps maintain a strong and healthy body, improves cardiovascular function, and aids in the prevention of chronic diseases.
3. Varied Diet
A diverse and nutrient-rich diet also plays a crucial role in longevity. Participants who consumed a wide variety of foods, particularly those rich in vitamins and minerals such as fruits, vegetables, whole grains, and lean proteins, had a higher probability of living longer.
