Positive emotions may promote heart healthy behaviours

Washington | People with heart disease may benefit from maintaining positive emotions, according to a new study. The study tracked more than 1,000 patients with coronary heart disease over the course of five years. Patients who reported higher positive psychological states were more likely to be physically active, sleep better and take their heart medications and were also less likely to smoke, compared to patients with lower levels of positive states. 

Negative emotions and depression are known to have harmful effects on health, but it is less clear how positive emotions might be health-protective, said Nancy L Sin, postdoctoral fellow in the Center for Healthy Aging and in the department of biobehavioural health at Penn State. We found that positive emotions are associated with a range of long-term health habits, which are important for reducing the risk of future heart problems and death, Sin said.
The researchers assessed psychological well-being of participants at baseline and again at a five year follow-up by asking the participants to rate the extent that they had felt 10 specified positive emotions, including interested, proud, enthusiastic and inspired. Physical activity, sleep quality, medication adherence and alcohol and cigarette use were also measured at baseline and again five years later.
Higher levels of positive emotions were associated with less smoking, greater physical activity, better sleep quality and more adherence to medications at baseline, said the researchers. They found no correlation between positive emotions and alcohol use. The results took into account patients demographic factors, depressive symptoms and the severity of their heart conditions.
Though positive emotions at baseline did not predict changes in health behaviours five years later, increases in positive emotions across the five-year period were associated with improvements in physical activity, sleep quality and medication adherence. There are a number of reasons why positive emotions are linked to optimal health habits, the researchers suggest. People with greater positive well-being may be more motivated and persistent in engaging in healthy behaviours.
They might have more confidence in their abilities to maintain routines such as physical activity and sleep hygiene. Positive emotions may also enable people to better adjust their health goals and to proactively cope with stress and setbacks. Efforts to sustain or enhance positive emotions may be promising for promoting better health behaviours, said researchers.
