Happiness vs personality and health

Happiness vs personality and health
Two personality traits shine through the complexity of economists’ regression analyses: neuroticism and extroversion. Neurotic people—those who are prone to guilt, anger and anxiety—tend to be unhappy. This is more than a tautological observation about people’s mood when asked about their feelings by pollsters or economists. Studies following people over many years have shown that neuroticism is a stable personality trait and a good predictor of levels of happiness. Neurotic people are not just prone to negative feelings: they also tend to have low emotional intelligence, which makes them bad at forming or managing relationships, and that in turn makes them unhappy.

Whereas neuroticism tends to make for gloomy types, extroversion does the opposite. Those who like working in teams and who relish parties tend to be happier than those who shut their office doors in the daytime and hole up at home in the evenings. This personality trait may help explain some cross-cultural differences: a study comparing similar groups of British, Chinese and Japanese people found that the British were, on average, both more extrovert and happier than the Chinese and Japanese.

Happiness and health

Happiness doesn’t just make people happy—it also makes them healthier. John Weinman, professor of psychiatry at King’s College London, monitored the stress levels of a group of volunteers and then inflicted small wounds on them. The wounds of the least stressed healed twice as fast as those of the most stressed.

At Carnegie Mellon University in Pittsburgh, Sheldon Cohen infected people with cold and flu viruses. He found that happier types were less likely to catch the virus, and showed fewer symptoms of illness when they did. So although old people tend to be less healthy than younger ones, their cheerfulness may help counteract their crumbliness.

Happier people are more productive, too. Mr Oswald and two colleagues, Eugenio Proto and Daniel Sgroi, cheered up a bunch of volunteers by showing them a funny film, then set them mental tests and compared their performance to groups that had seen a neutral film, or no film at all. The ones who had seen the funny film performed 12% better.
