Abstract

Research on emotion and health has tended to focus on the negative consequences of “negative” emotions. An emerging literature has begun to explore the positive aspects of negative affect, suggesting that emotion be treated in a more differentiated way by recognising the components and intensity that can promote or harm health. For example, short bursts of emotion-associated sympathetic activation can stimulate parts of the immune system, whereas more chronic activation can cause “wear and tear” on the cardiovascular system. Anxiety and guilt have been associated with preventive health behaviours and care-seeking, whereas distress and depression increase symptom sensitivity, accuracy of illness perception, and can facilitate care-seeking and receipt of support. However, intense and chronic negative affects may lead individuals to engage in risky health behaviours, such as substance abuse, overeating, and high risk sex, as a coping mechanism to regulate negative emotion. They may also undermine social support systems, leading to a self-perpetuating cycle of conflict and isolation. Future research must address the parameters defining “healthy” and “unhealthy” negative emotion.
