Type C personality traits
Type C personalities love details and can spend a lot of time trying to find out how things work and this makes them very suitable for technical jobs. Type C are not assertive at all and they always suppress their own desires even if there is something that they dislike. The lack of assertiveness results in tremendous stress and sometimes in depression. Type Cs are very vulnerable to depression compared to type A and type B.
A Type C personality is designated to individuals who appear to be cancer-prone – someone who responds to stress with depression and a sense of hopelessness, and has a higher risk for developing cancer. They tend to be introverted, respectful, eager to please, and compliant.
Type D personality traits
D stands for distressed, Type D’s have a negative outlook towards life and are pessimistic. A small event that is not even noticed by type B can ruin type D’s day.
Type D might become socially withdrawn as a result of fear of rejection even if they like to be around people. T
Type D’s are famous for suppressing their emotions and this makes them the most vulnerable type to depression. One of the famous causes for depression is suppressing your emotions for long periods of time without venting them someway.
Researchers analyzed data from more than 6,000 patients in 49 studies, and found that heart patients with a Type D personality, had a three-fold increased risk for future cardiovascular problems. This type of individual experienced increased levels of anxiety, irritation, and depressed mood.
There is some criticism that this sort of personality typing is overly simplistic and incapable of assessing the degrees in differences in human personality. As a matter of fact, bio-statisticians at the University of Michigan, as well as researchers from Italy, Sardinia, and the U.S. National Institute on Aging, conducted a 10 year study with findings that showed absolutely no link between a personality type and increased health risks and patterns of behavior.
