News — NK cells

In today’s fast-paced, digitally-driven world, finding moments of true connection with nature has become more than a luxury—it’s a necessity. Forest bathing, known as “Shinrin-yoku” in Japan, is the simple yet powerful practice of immersing oneself in the atmosphere of the forest. It doesn’t involve hiking, exercising, or any physical strain; rather, it’s about being present, breathing deeply, and absorbing the forest through all five senses. This immersive experience has been scientifically proven to offer a wide range of health benefits, particularly in boosting the immune system.

One of the most fascinating discoveries in forest bathing research is its ability to increase the activity and count of Natural Killer (NK) cells—powerful immune cells that play a critical role in our defense against viruses, infections, and even tumor formation. These effects aren’t just fleeting; studies have shown that a single forest bathing trip can elevate NK cell activity for days, even weeks. In this article, we’ll delve deep into the science and soul of forest bathing, exploring how trees and their invisible allies—phytoncides—can significantly enhance your immune function.
