What are psychological factors that are related to good health? Can it be conclu

Positive emotions seem to protect against physical disease or speed recovery when disease occurs. A patient who believes that a treatment will work (a placebo effect) has a better chance of improving than a person who is neutral or pessimistic about the treatment. Conversely, negative emotions such as anger, anxiety, and depression are correlated with increased likelihood of disease. While these correlations can be observed, they are merely correlations and a causal relationship can not be assumed. It may be that those who are more positive may behave in ways that are more healthy, decreasing the likelihood of illness and improving recovery when illness does occur. There have, however, been studies that have revealed positive effects of attitude and social support on immune function, suggesting that the relationship may be direct in some instances.
