Japanese Study Finds Forest Bathing Boosts Immune Cells for Over 30 Days
Japanese research on Shinrin-yoku, or forest bathing, shows that spending three days in a forest can boost natural killer (NK) cells, which support the immune system, for over 30 days. This practice involves slow, relaxed walks in nature without exercise or supplements. Studies compared forest visits to city walks, finding immune benefits unique to forest environments. While not a cure, forest bathing may enhance the body's defenses and promote well-being through closer contact with nature.
