Forest Therapy in Breast Cancer Patients 

A South Korean study was curated online in the Natural Medicine Journal and detailed how immersion in a forest can help those with breast cancer.

The study included 11 women, aged 25 to 60 that were living in Seoul, South Korea that were being treated for stage 1-3 breast cancer. The women were brought to a forested national park for two weeks for what is called “forest therapy.” During their time in the forest, the individuals stayed in log cabins, hiked, and were otherwise immersed in the environment.

Baseline blood samples were taken and all participants were otherwise healthy and there were no detectable physical or mental health issues.

The results of the study were that the NK (natural killer) cell count increased 39 percent directly after the forest therapy. A week later it had subsided, but was still elevated 13 percent relative to baseline.

The importance of this study is that standard medical treatment for breast cancer (eg, surgery, radiation, chemotherapy) can be rigorous and immunosuppressive. Reducing or destroying the tumors comes at a price. The forest therapy attempts to treat the problem without the side effects.
