A growing number of health experts are pointing to an ancient Japanese practice called "forest bathing" as a simple, drug-free way to lower stress and improve overall well-being. Dr. Andrew Weil, a physician affiliated with Mass General Brigham, recently highlighted the practice, explaining that it involves more than just a walk in the woods. Forest bathing, or shinrin-yoku, encourages people to slow down and engage all five senses while immersed in a natural setting.

The idea is not to hike or exercise but to absorb the atmosphere of the forest. Dr. Weil notes that research suggests this mindful exposure can lower cortisol levels, reduce blood pressure, and boost the immune system. The practice originated in Japan in the 1980s as a response to tech burnout and urban stress.

For those interested in trying it, experts recommend leaving phones behind and focusing on the smell of pine, the feel of bark, the sound of rustling leaves, and the sight of dappled sunlight. Even 20 minutes of forest bathing can produce measurable benefits. As Dr. Weil puts it, nature offers a reset button that costs nothing and has no side effects. With stress-related illnesses on the rise, this simple remedy is gaining attention as a practical tool for mental and physical health.
