Research on Emotional Changes in Children With Water-Based Nail Treatments—Intervention in a Child Welfare Facility and Examination of Its Effects

We investigated the psychological effects of nail treatments on children living in child welfare facilities.We performed a single nail treatment on children living in child welfare facilities.As a result, we found that feelings of "energy", "relaxation", and "comfort" tended to increase more strongly after the treatment than before.Furthermore, these feelings increased even more after the nail treatment.The effects of nail treatments were unrelated to gender or previous nail experience.Furthermore, nail treatments increased communication and interaction with facility staff and other children residing in the facility, promoting self-expression, and, as a result, increasing a sense of accomplishment, acceptance from others, and self-esteem.This suggests that positive emotions persisted even after nail treatments, leading to positive changes in daily life.
