RESUMO
This pilot study was a randomized controlled trial that aimed to investigate the effect of the warm footbath on the sleep quality of Iranian older adults. Males and females aged over 60 were randomly divided into three groups (footbath group with water at 40°C, footbath group with water at 37°C, and one control group) using the permutation block method. Repeated measures design was used to compare the groups after week two and week four to study the effects of footbath on sleep quality. Footbath with water at 40°C and 37°C caused significant improvement in the participants' sleep quality. No significant difference was found between the participants' sleep quality treated with water at 40°C and 37°C. Future studies with larger samples are recommended for assessing the effectiveness of warm footbath in enhancing sleep quality in older adults.
