A study suggests that spending three days in the forest can increase the activity of NK (Natural Killer) cells, which are part of the immune system and help the body fight damaged cells, including cancerous ones, by nearly 80%.
According to researchers, clean air, stress reduction, and natural compounds released by trees have a positive effect on strengthening the immune system and increasing the body's ability to defend itself.
Experts emphasize that being in nature does not replace medical treatments, but can be a useful way to support physical and mental well-being, once again showing the importance of connecting with nature for health.
