Bragging on twitter / Facebook / blogs can feel as good as sex, researchers have revealed.

A team from Harvard University found that talking about ourselves triggers the same sensation of pleasure in the brain as food, money and even sex.

They say it could explain why 40 per cent of everyday speech is devoted to telling others about what we feel or think.

‘Self-disclosure is extra rewarding,’ according to Harvard neuroscientist Diana Tamir, who conducted the experiments with her colleague Jason Mitchell.

‘People were even willing to forgo money in order to talk about themselves. This helps to explain why people so obsessively engage in this behaviour. It’s because it provides them with some sort of subjective value: It feels good, basically.

The team offered participants money if they chose to answer questions about other people, such as President Obama, rather than about themselves.

Questions ranged from whether they liked mushrooms on a pizza and enjoyed snowboarding to their views on personality traits, such as intelligence, curiosity or aggression.

Brain scans also confirmed that when they chose to talk about themselves, the mesolimbic dopamine system in the brain became active—the same area that responds to reward and satisfaction from food, money or sex.
