How you think about your health can have powerful impacts on how you experience your health. In a recent study with a group of cardiac patients, how people thought about their illness (termed “illness cognitions”) was found to have a direct impact on how people experience health and emotional wellbeing [1]. These illness cognitions also affected health indirectly by influencing the types of behaviours people were engaged in to cope with cardiac problems. This study brings to our attention the relevance of psychology in relation to medical illnesses.
