Do you want to live longer?
I’ve always been fascinated by the science of aging and even more so, by the concept of immortality. This may or may not be related to a small crush I had on Jesse Tuck, played by Jonathan Jackson in the movie, Tuck Everlasting. In it, a young girl named Winnie Foster meets and falls in love with the son of a family of immortals leading to questions of love, life and many other stereotypical romantic drama themes. But, I digress.
So what does personality have to do with living longer?
Researchers have determined that regardless of age, gender or nationality, there are five core personality traits that everyone has. These five traits are classified as OCEAN (or the Big 5):
- Openness
- Conscientiousness
- Extroversion
- Agreeableness
- Neuroticism
Here’s a quick overview of the personality traits:
Throughout the years, scientists have conducted research to determine how we can optimize these personality traits to live better, healthier lives. Of these Big 5 listed above, your levels of conscientiousness, extroversion and agreeableness are the proven traits that have a direct influence with how healthy you are and how long you will live.
How Your Personality Traits Affect Your Lifespan
1. Conscientiousness
A 75-year longitudinal study conducted by Joshua Jackson (no relation to Jonathan Jackson that I know of), determined that men with conscientious personality traits have been known to live longer.
Conscientiousness is the trait that describes how organized and dependable you are. People high in this trait have high self-discipline, are very organized and prepared and like to plan things out instead of being spontaneous.
This makes sense when you think about it. High-conscientious men would be less likely to do something spontaneous and potentially life-threatening. Further, being dependable and strict with self-discipline is a much safer lifestyle choice.
2. Extroversion
Extroversion describes how you interact with people. People who are high in extroversion (extroverts) are outgoing and energetic, while people who are low in extroversion (introverts) are more solitary and reserved, and typically require recharge time from social interaction. As it turns out, people who are more outgoing and sociable have the strongest immune system, compared to those who are more introspective and introverted.
To test this, participants in a recent study had blood samples taken for measuring genetic factors and their immune system. They were then given a personality test to see where they fall on the Big 5 spectrum. Those who were labeled as extroverted appeared to have immune systems strong enough to deal with their socially oriented nature, where introverts had weaker ones.
This study proves that the bodies of extroverted people are primed to have stronger immune systems since they are more exposed to germs or sickness as they interact with more people on a regular basis.
3. Agreeableness
Agreeableness is how you feel towards others. People who are high in agreeableness are friendly, compassionate and very optimistic–they are collaborative and team-players. Research has shown that people high in agreeableness and optimism have healthier hearts than those who are pessimistic or neurotic .
Even when adjusted to include socio-demographic characteristics like age, income, education and poor mental health, the results remained consistent: agreeable, optimistic people had better cardiovascular health. Not only that, but they were less stressed, had a healthier body mass index and were less likely to smoke–all of which are major factors that can affect your heart health.
Highly agreeable people are better at using coping strategies and because they are naturally more empathetic and compassionate, they’re also more likely to reach out for support when in need and help others.
