Having higher levels of trait of the neuroticism may reduce the risk of death for those that hav poor health. An aspect of neuroticism related to worry and feelings of vulnerability was associated with lower mortality, irrespective of state of health.
Being high in neuroticism may sometimes have a protective effect, perhaps by making people more vigilant about their health. People with high levels of neuroticism may experience negative emotions like irritability, frustration, nervousness, worry, and guilt compared with those who have lower levels of neuroticism.
The link between neuroticism and risk of death may depend on how people rate their health. The protective effect was present in people who rated their health very low or does not really care about what will happen to their health.
Behaviors like smoking, exercise, diet and alcohol consumption did not have any link with vulnerability and mortality risk. Worry and vulnerability to sicknesses and diseases might encourage people to behave in a healthier way and hence lower their risk of sudden death.
