Blood Pressure and Personality Type

Gewissenhaftigkeit ist gut für den Blutdruck

1. Openness to New Experiences

Refers to how curious and creative someone is. High openness is seen in people who are interested in new ideas and like to try new things. Less open people prefer routines and clear rules. 

2. Conscientiousness

Refers to how organized and reliable someone is. People high in conscientiousness plan well, work carefully, and keep appointments. Less conscientious people tend to be more spontaneous and sometimes disorganized.

3. Extraversion

Refers to how sociable and outgoing someone is. Highly extraverted people are active and enjoy being around others, and they usually like to talk. Less extraverted people are quieter and need more time alone.

4. Agreeableness

Refers to how friendly and helpful someone is. People high in agreeableness are compassionate, cooperative, and considerate. Low agreeableness shows up as being more critical and assertive. 

5. Neuroticism

Refers to how prone someone is to negative feelings. People who score higher tend to get stressed, anxious, or insecure more easily. Those who score lower are more emotionally stable and calm. 

Important: Everyone has all five traits just in different amounts.

What a Japanese long-term study on the "Big Five" found

Can our personality affect whether we develop high blood pressure? A team led by Sixin Deng (Waseda University, Tokyo) investigated this question in a four-year longitudinal study. The results offer interesting clues but they also make clear: personality is not a main factor, but one possible additional influence among many.

Study overview

• Study design: 4-year longitudinal study
• Participants: 7,321 adults in Japan
• Period: 20192022
• Personality assessment: "Big Five" (short scale TIPI-J)
• Endpoints:
  • New-onset high blood pressure ("incident hypertension")
  • Sustained high blood pressure ("sustained hypertension")
• Statistics: Statistical analysis comparing multiple possible outcomes while adjusting for factors like age, sex, and income.

Important: The analysis accounted for known influencing factors. The effects of personality were calculated in addition to those.

Detailed results

1. Conscientiousness

Result: Lower risk of high blood pressure.

Higher conscientiousness was statistically significantly associated with a reduced risk of both new-onset and sustained high blood pressure.

How strong was the effect? The calculated odds ratios were just below 1. That means: as conscientiousness increased, the likelihood of high blood pressure decreased but only to a moderate extent.

Interpretation: The effect was statistically significant but small to moderate. Personality does not replace classic risk factors such as overweight, lack of physical activity, or salt intake.

2. Openness to Experience

Result: Slightly increased risk of sustained high blood pressure.

Higher openness was associated with a increased risk of sustained high blood pressure.

How strong was the effect? The odds ratios were slightly above 1. Again, this was a small but statistically significant effect.

This association was not consistent for new-onset high blood pressure.

3. Extraversion

Result: No significant association.

After adjusting for other factors, there was no reliable effect on hypertension risk.

4. Agreeableness

Result: No significant association.

Here too, the models showed no significant change in risk.

5. Neuroticism

Result: No independent effect.

Although neuroticism is often linked to stress, this analysis did not find an independent statistical association with high blood pressure.

How should these effects be interpreted?

Key points for interpretation:

• The effects were statistically significant but not large.
• The odds ratios were close to 1 so these are not large changes in risk.
• Age, sex, and other classic risk factors had much stronger effects.

This means: personality can play a supporting role, but it is not a dominant risk factor.

Possible explanation

Why might conscientiousness be protective?

People with high conscientiousness:

• are more likely to follow doctors' recommendations
• measure their blood pressure more regularly
• pay more attention to diet and exercise
• take medications more reliably

So personality likely works indirectly through behavior.

What does this mean for you?

Your personality does not determine whether you will get high blood pressure. But certain traits especially conscientiousness may help you stick to healthy routines more consistently.

What matters are:

• regular blood pressure checks
• physical activity
• a balanced diet
• weight management
• consistent medication adherence

Personality is an interesting additional factor your behavior remains the most important lever.
