Link Between Positive Emotions and Health May Depend on Culture
Positive emotions are often seen as strongly linked to physical health, but a new study published in the journal Psychological Science suggests that the link between emotion and health may vary by culture. The findings show that experiencing positive emotions is linked with better cardiovascular health in the U.S. — but not in Japan.
“Our key finding is that positive emotions predict blood-lipid profiles differently across cultures,” said psychological scientist Jiah Yoo, a graduate student at the University of Wisconsin-Madison.
“American adults who experience high levels of positive emotions, such as feeling ‘cheerful’ and ‘extremely happy’, are more likely to have healthy blood-lipid profiles, even after accounting for other factors such as age, gender, socioeconomic status, and chronic conditions. However, this was not true for Japanese adults,” she said.
“Our findings underscore the importance of cultural context for understanding links between emotion and health, something that has been largely ignored in the literature,” said Yoo.
“Although some studies have examined cultural differences in links between positive emotions and healthy functioning, this work is novel in that it includes biological measures of health and large representative samples from both countries.”
The fact that positive emotions are thought of and valued differently across cultures led the researchers to wonder whether the health benefits observed in tandem with positive emotions might be specific to Western populations.
“In American cultures, experiencing positive emotions is seen as desirable and is even encouraged via socialization. But in East Asian cultures, people commonly view positive emotions as having dark sides — they are fleeting, may attract unnecessary attention from others, and can be a distraction from focusing on important tasks,” said Yoo.
For the study, the research team designed a cross-cultural comparison, examining data from two large representative studies of adults: Midlife in the United States and Midlife in Japan, both funded by the National Institute on Aging.
Participants rated how frequently they felt 10 different positive emotions in the previous 30 days and underwent tests of blood lipids, which provided objective data on heart health.
“Because of the global prevalence of coronary artery disease, blood lipids are considered important indices of biological health in many Western and East Asian countries,” said Yoo.
As expected, the findings showed a link between experiencing frequent positive emotions and healthy lipid profiles in American participants. But there was no evidence of such a link for Japanese participants.
One potential reason for this could come down to the association between positive emotions and BMI in each culture. Greater levels of positive emotions were linked with lower BMI and, in turn, healthier lipid profiles among American participants, but not among Japanese participants.
“By demonstrating that the cultural variation in the connection between emotional well-being and physical well-being, our research has wide-ranging relevance among those who seek to promote well-being in the communities and the workplace, including clinicians, executives, and policy makers,” said Yoo.
In the future, the researchers plan to investigate longitudinal data to determine whether the evidence suggests a direct causal link between emotions and health. They also hope to identify emotional profiles that may be more relevant or important to health outcomes in East Asian cultures.
