ABSTRACT This study, conducted in June and July 2022 through purposive sampling, aimed to explore the relationship between sleep and health performance in 33 pairs of elderly individuals and their migrant caregivers in southern Taiwan. Participants completed a structured questionnaire and wore an Actiwatch for seven days. Pearson correlation and independent t-test were used for analysis. Nearly 50% of foreign home care workers suffered from insomnia, and 80% of elderly care recipients with disabilities experienced sleep disorders. The number of chronic illnesses and/or dementia among the elderly and insomnia among care workers were associated with poor self-perceived health (r = –0.667, p < .001) and sleep disorders among the elderly (r = 0.368, p = .035). The problem of caregiving should be addressed. Future studies should increase the sample size and extend the duration of the study to enhance the generalizability of the findings.
