Forget self-control, getting angry is really good for you

Getting angry is good for you because it reduces the negative impact of stress, according to scientists.

A new study says the emotion increases blood flow to the part of the brain which is involved in experiencing positive feelings.

Researchers induced anger in 30 men in a laboratory experiment, measuring the subjects' heart rate, arterial tension, stress hormones testosterone and cortisol and scanning their brains both before and after the test.

Dr Neus Herrero, of the University of Valencia, said the left hemisphere of the brain - associated with experiencing positive emotions - became more stimulated.

It is the first time all the different psycho-biological elements have been investigated in a single study after the inducement of anger.
