Feeling good is linked to better health in Western contexts. Recent studies show, however, that the affect-health link is not consistent across cultures. We suggest two reasons for such inconsistency. The first follows from research showing that North American (versus East Asian) cultures tend to value high arousal positive (HAP) states, e.g., excited, more than low arousal positive (LAP) states, e.g., calm. The second is one we propose for the first time. Positive affective experience is manifest in internal feelings but also in affective practices such as taking a bath (a highly valued affective experience in Japan) or a fitness workout (a highly valued affective experience in the U.S.). We hypothesized that the HAP feelings/practices-health link would be stronger in the U.S. versus Japan, and the LAP feelings/practices-health link would be stronger in Japan versus the U.S.. Using survey samples from the U.S. (N = 640) and Japan (N = 382), we examined how health outcomes are shaped by positive affective feelings and practices varying in arousal. In a first set of analyses, HAP feelings predicted better physical and biological health in the U.S. but not in Japan. No cultural differences were consistently found for the effect of LAP feelings on health. In addition, engaging in HAP practices predicted better physical and biological health in the U.S.
