NCT ID NCT05012813
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether breathing in humidified wood or fragrant oils could mimic the immune-boosting effects of a forest walk. 28 adults who finished chemotherapy or radiation for early-stage breast or prostate cancer took part. The goal was to see if this approach is practical and to measure changes in natural killer cells, which help fight infections and cancer.
