Our daily lives, together with our past emotions leave us open and more vulnerable to more stress and illness. For example, going through a divorce, problems at work, or dealing with an abusive partner. Although we put some of those bad changes down to stress, we can also be stressed through life changing experiences that are considered good, like having a baby or moving house.
Unfortunately, illness cannot always be cured through positive thinking. It obviously depends on the illness. Someone with a cough or a cold and who has a positive attitude will allow their body to heal a lot quicker, than someone who is predisposed to negativity with the same symptoms. This has been well documented over the years through research.
There are also other reasons why we may become ill, such as environmental, dietary, genetic and hereditary dispositions. The key is to look at those predispositions. Obviously, it will depend on the predisposition, whether the link is genetic or not, like carrying a gene that holds a predisposed condition, such as Breast Cancer that cannot be changed.
An unhealthy lifestyle can be a contributing factor to illness, but can be prevented even with a family history. A relevant example might be a predisposition to being overweight, leading to diabetes, which may successfully be addressed through a better diet and lifestyle.
