International physical activity guidelines suggest that adults should engage in at least 150 min of moderate-intensity aerobic physical activity per week, at least 75 min of vigorous-intensity aerobic physical activity throughout the week, or an equivalent combination of moderate- and vigorous-intensity activity. This seems to imply that little or no health benefits can be reaped from light-intensity physical activity (LPA; e.g., walking slowly, shopping, walking a dog, lifting lightweight objects, and doing household chores). However, an increasing body of evidence indicates that LPA may provide health benefits for adults and older adults. This review examined several crucial aspects of LPA and health and assessed whether the health benefits of LPA for adults aged 18 or older are underestimated. The following procedures were implemented to review the evidence of device-based measurements of LPA and health. First, the country profiles of adults performing LPA were described. Second, evidence obtained through systematic reviews and meta-analyses was examined to explore how LPA relates to mortality, morbidity, and other health outcomes. Finally, research topics regarding whether the health benefits of LPA for adults are underestimated were evaluated. In summary, evidence from systematic reviews and meta-analyses based on device-based assessment of LPA supports the health benefits of LPA for adults, which are independent of the effects of moderate-to-vigorous-intensity physical activity. Although some studies have suggested that adults can achieve health benefits by engaging in LPA for at least 6 hours per day, further research is needed to confirm this finding.
