Certain personality characteristics may influence health status, because personalities are the result of genes and the environment in which that person lives, according to dailymail.co.uk.
Belonging to a particular type of personality does not mean that you will develop a certain disease, but you must take into account the risk and act on those aspects of nature that may influence the occurrence of disease, says psychologist Martin Hagger, University of Nottingham, UK.
Below are a number of diseases associated with the most common types of personalities:
These people see the glass half full, however they tend to become overweight. Researchers at Doshisha University in Kyoto, Japan and other medical centers evaluated overweight people who followed a diet for a period of six months, involving counseling, nutrition and sports. Researchers found that those who were more optimistic weakened the least . Optimists care less about their weight problem and don’t resist to temptation.
However, optimists have more risk to die prematurely because they have greater confidence in their abilities to overcome difficulties and therefore they assume more risks, according to a study by researchers at the University of California, attended by over 1,500 children monitored from age 10 until they become adults. People with a developed sense of humor lived on average less than those who were not so happy. Another study conducted at Stanford University found that, in general, most cheerful children at maturity tend to become smokers, alcohol drinkers and have dangerous passions.
Researchers at the University of Descartes, Paris, and the Centre for Addiction and Mental Health in Toronto found that anxious people are five times more likely to develop stomach ulcers. However, these individuals are more likely to smoke, to drink, to have bad eating habits and sleep problems – all this leads to increasing acidity in the stomach, causing ulcers.
Also, these people may have high levels of cortisol in the body – the stress hormone – causing headaches, acne and gallbladder infections.
But anxious people may get a richer sex life, according to a study by researchers at the University of Sheffield. “Neurotic women have higher probabilities of having more short-term relationships, this suggests a link between sexual desire and anxiety,” said Dr Virpi Lummaa of the University of Sheffield. It is possible that fear of not finding the right person or to not have offspring could determine these people to have more short-term sexual relationships.
Men who have traits considered “feminine” – demonstrating, for example, empathy and compassion – have lower stress levels and a reduced risk of having a heart attack, researchers from the University of Glasgow say. In a study conducted by the institution, men were judged on their traits “masculine” – leadership skills, strength, aggression, risk-taking – and “female” – empathy, compassion and sensitivity to the needs of others. Risk of suffering a heart disease was inversely proportional to the feminine traits of volunteers. Men who are able to talk about their emotions will seek the help of others – including medical help.
Angry people react quickly and strongly to stress, both mentally and psychologically, which causes increased blood pressure and pulse. Hostility and aggressive attitude is one of the most unhealthy personality traits. In a study involving 448 women who had mammograms done at several medical centers, researchers at Oncology Hospital of Kifissia, Athens, established that people with aggressive character were more likely to be diagnosed with breast cancer.
In another study involving 61 men with colon cancer, conducted at Creighton University School of Medicine, Nebraska, it was discovered the same thing. It seems that anger affects the strength of the immune system, making the body more vulnerable to disease. However, the risk of heart disease increases by 50%, say researchers at Mount Sinai School of Medicine in New York.
Extroverted men show a higher probability of having more children. Physically they are not more fertile, but they are very revelers, which increases by 14% the possibility of having more children than less open people, say researchers at the University of Sheffield.
Extroverted men have less risk of suffering from heart disease, according to a study by researchers at the University of Milan. They are less exposed to infections and tend to recover better after an illness. This is due to a lower level of stress hormones – extroverted people can cope better with problems. And if they have a medical problem most likely they will talk openly about it.
Shy people have a 50% higher risk of suffering a stroke or a heart attack. Researchers at Northwestern University, Chicago, conducted a study that was spread over 30 years and have found that shy people lead quiet lives, not take risks, and any new situation for them can be a source of stress.
Shy people are more susceptible to viral infections including the common cold – no matter of the season – according to a study by the University of California, stress is guilty for this. “It seems that sensitive people respond more aggressively to stress than others,” says Bruce Naliboff, one of the researchers.
A low IQ is associated with a higher risk of anxiety, dementia and posttraumatic stress disorder, say researchers at Edinburgh University.
Also, a study of Harvard School found that children with a low IQ show increased risk of schizophrenia and depression. One possible explanation is that people with a lower level of intelligence find it more difficult to understand the importance of a healthy life.
Honest people have less risk of becoming ill in general (of any type of disease: diabetes, hernia, bone disorders, sciatica, stroke, Alzheimer’s), say researchers at the University of Edinburgh and the department of social and public health from Glasgow. A research that was based on 190 studies found that honest people generally live a healthy life, doing sports and having a proper diet.
