Young adults with a short temper or mean disposition also tend to have compromised lung function, according to a recent study published in the journal Health Psychology. This occurred even when asthma and smoking were ruled out as possible causes of lung dysfunction.
In a study of 18-30 year olds, psychologists examined whether the tendency to be hostile went along with having decreased lung function in otherwise healthy young adults.
The results indicated that the more hostile one's personality and characterised by aggression or anger, the lower one's levels of lung function. The findings held firm even after controlled group for age, height, socio-economic status, smoking status and presence of asthma.
