Think theres not a link between your heart health and your personality? Studies conducted at Tilburg University in the Netherlands show that chronically stressed out patients had a higher risk of heart attack. In fact, results indicate those with a history of heart disease who are classified as Type D (distressed) personalities are four times more likely to experience cardiovascular disorders compared to other personality profiles. Researchers also stated that Type D personalities are prone to other detrimental habits, including tobacco smoking, overeating and increased alcohol consumption. The study, which appears in the journal Circulation, notes that Type D personality and depression are not one in the same. Depression tends to come in episodes, while personality traits are chronic and signal an overall mood state that may not materialize into depression.
