Background Wellbeing among postpartum women needs to be assessed. This article aimed to evaluate the effectiveness of photobiomodulation near infrared as a cultural nursing intervention for postpartum women in Indonesia. Methods A research and development study design was undertaken from 2018 to 2020 in three stages to evaluate the effectiveness of photobiomodulation near infrared: a phenomenological study (n=20), a pre-experimental study (n=80) and a quasi-experimental design (n=90). Data were analysed using one-way ANOVA and a Kruskal Wallis test. Results Three themes emerged from the qualitative study that focused on development tools. Photobiomodulation near infrared was developed to cover postpartum women s needs. Significant statistical differences were found in multiple outcome measures after implementing photobiomodulation near infrared. Conclusions Photobiomodulation near infrared is a promising intervention for postpartum mothers.
