It may contradict common wisdom but getting angry is good for you it seems.
The emotion actually reduces the negative impact of stress, according to scientists.
It increases blood flow to part of the brain which is involved in experiencing positive feelings, a study has found.
Researchers induced anger in 30 men with a simple laboratory method using 50 recognised phrases intended to aggravate.
Before and immediately after the experiment they measured the subjects' heart rate, arterial tension, stress hormones testosterone and cortisol while scanning their brains.
Dr Neus Herrero and colleagues said their findings, published in the journal Hormones and Behaviour, showed the left hemisphere of the brain became more stimulated.
Dr Herrero, of the University of Valencia, said the left frontal region of the brain is involved in experiencing positive emotions, while the right is more related to negative emotions.
The left frontal area also triggers 'closeness' which can generate happiness, whereas the right provokes withdrawal, fear and sadness.
