People with high levels of neuroticism are more likely to experience negative emotions like frustration, nervousness, worry and guilt. However, it’s these negative emotions which may bring about a positive result. “Our findings are important because they suggest that being high in neuroticism may sometimes have a protective effect, perhaps by making people more vigilant about their health,” says the lead researcher Catharine Gale.
The study in Psychological Science found that, when adjusted for the study participant’s self-rated health, higher neuroticism was linked with a slightly lower risk of death from all causes and from cancer. Disclaimer: this protective effect only occurred in people who said they were in fair or poor health.
However, one particular type of neuroticism reduced the risk of death – whether in excellent or poor health. “We also found that people who scored highly on one aspect of neuroticism related to worry and vulnerability had a reduced risk of death regardless of how they rated their health,” Gale explains.
The researchers now want to find out why worry and vulnerability in particular can help protect your health. “We had thought that greater worry or vulnerability might lead people to behave in a healthier way and hence lower their risk of death, but that was not the case,” Gale says. Finally, good news for worry warts.
