What is the lasting impact of forest bathing on immune function?

Question

Accepted Answer

Forest bathing can boost natural killer cell activity for up to 30 days
Forest bathing is associated with increased activity in Natural Killer (NK) cells, which help identify and eradicate cancer cells. That heightened NK activity can last for up to 30 days after a forest bathing session, alongside higher levels of anti-proteins such as perforin, GRN, and GrA/B.
NK cell activity increases and can persist for a month
Observations described in the clinical research link forest environments to higher NK cell activity. The increased activity is reported to continue for up to 30 days after a single session of forest bathing.
Tree-emitted phytoncides are tied to NK-related immune changes
The work explains that trees transmit phytoncides, compounds said to affect NK cells. In addition to increasing NK cell number and activity, the report describes higher levels of anti-proteins including perforin, GRN, and GrA/B.
The immune effects are framed as strengthening defences, not replacing treatment
The material characterises forest bathing as a way to strengthen the immune system, with particular effects that may help stave off cancer. It explicitly does not frame forest bathing as a substitute for chemotherapy, instead treating the immune changes as supportive.
The lasting impact is tied to a forest session rather than an immediate effect
The key time window given is that the NK-related increase can remain for as long as 30 days after the session. This places the lasting impact in a multi-week period rather than only hours or days after spending time in nature.
