It's great news for argumentative types. According to the study, which was recently presented at the Convention of the American Psychological Association, people who bottle up their feelings experience abnormal levels of the stress hormone cortisol throughout the day and not just during moments of tension.
And when you have cortisol running through your veins constantly, you're more likely to feel upset and angry as well as suffer physical symptoms such as nausea and aches and pains, say the researchers. Blowing your top, on the other hand, helps diffuse tension. And when you're not tense, you feel a whole lot better, both emotionally and physically.
Still not convinced you should always have your say?
Well it's not the first time experts have looked at whether or not arguing is good for you. Previous research suggests married couples who avoid arguments don't live as long as those who have a more fiery relationship. And another study claims people who express their anger freely are more positive and optimistic than those who shrink from a good old bust-up.
So what's your style when it comes to confrontation? Do you firmly stand your ground? Or do you ignore conflict and hope it will just go away? Do you feel better when you do have it out? Tell us your thoughts.
