Foot care nursing is attracting attention as a medically effective treatment for the foot lesions caused by such problems as diabetes or aging. In this study, we experimentally examined how aromatherapy affects human brain functions during foot care nursing using near-infrared spectroscopy (NIRS). 11 subjects received both foot care nursing massages and aroma oil massages. We analyzed the changes in their oxygenated hemoglobin (oxy-Hb) concentrations based on their brain activity by t-tests, and the t-test results showed significant differences between two kinds of massages in both the somatosensory and prefrontal association areas. The oxy-Hb concentration in both massages with and without aroma oil also showed a tendency to decrease with time. Our questionnaire results showed that our subjects felt more comfortable and relaxed while receiving foot care nursing with aroma oils. These results suggest that aroma oil massages are an effective foot care nursing tool and that foot care nursing is a medically effective treatment.
