Discover how immersing yourself in Japan’s forests can rejuvenate your mind and body.
Just this week, I was asked several times about shinrin-yoku, also known as "forest bathing." This involves immersing oneself in nature to promote relaxation and well-being. You might think it’s just about enjoying fresh air and getting some exercise—but there’s so much more to it. In fact, science has proven that shinrin-yoku has significant health benefits.
As a sixth-year medical student on the verge of becoming a medical doctor, I’m excited to explore the science behind forest bathing and why it’s more than just a peaceful walk in the woods.

The Origins of Shinrin-Yoku: A Solution to Modern Stress
Shinrin-yoku originated in Japan in the 1980s, during a time when rapid technological advancements led to increased stress and burnout. Recognizing this, the Japanese government began encouraging people to practice shinrin-yoku—literally "taking in the forest air"—as a way to de-stress and improve overall well-being.
Since then, the practice has grown in popularity, not only in Japan but around the world, with many people embracing it as a natural way to relax, recharge, and reconnect with nature.
Why People Love Shinrin-Yoku (Even Before Knowing the Science!)
Many people are drawn to forest bathing for its immediate benefits, even without knowing the science behind it. Here’s why:
Mental Refreshment: Stepping away from city life into a peaceful forest helps clear the mind and promotes relaxation.
Gentle Physical Activity: Walking through nature provides low-impact exercise that supports overall health.
Engaging the Senses: The sights, sounds, and smells of a forest create a deeply calming and immersive experience.
But the benefits don’t stop there—science reveals that forest bathing has even greater effects on our health.
What Does Science Say About Forest Bathing?
Scientific studies have demonstrated that forest bathing can reduce blood pressure, lower stress hormones, and boost the activity of the autonomous nervous system. I’ll break down some of the key findings in simple terms.
1. Reduces Stress Hormones and Promotes Relaxation
When we experience stress, our bodies release cortisol, a hormone that helps us respond to challenges. However, too much cortisol over time can lead to anxiety, high blood pressure, and other health problems. Studies show that simply looking at a forest can reduce cortisol levels by 13.4%, and walking in the forest can lower them by 15.8%. This means that just being in nature actively reduces the body's stress response, helping you feel calmer and more at ease.
2. Activates the Body’s Natural Relaxation System
Our nervous system has two key parts: the sympathetic ("fight or flight") and the parasympathetic ("rest and digest") systems. Spending time in the forest enhances parasympathetic nervous activity, which helps our bodies relax. Research shows that looking at a forest increases relaxation-related markers in the body by 51.6%, while walking through a forest can increase them by 102%. This means forest bathing doesn’t just feel relaxing—it physically shifts your body into a state of deep rest and recovery.
There’s a graph showing the results of the data, but I feel like most people don’t really need it—so I’ll just leave the link to the research paper here.
3. Lowers Heart Rate and Blood Pressure
High blood pressure and an elevated heart rate are common signs of stress and are linked to long-term heart disease risks. Studies show that people who engage in forest bathing experience lower heart rates and blood pressure levels, reducing strain on the heart and promoting overall cardiovascular health.
4. Boosts the Immune System
Forest bathing has been shown to also increase the activity of natural killer (NK) cells, which are responsible for fighting infections and even cancerous cells. Research suggests that spending just a few days in a forest can significantly enhance immune function, with effects lasting for up to a month. This means that regular exposure to nature could help strengthen the body's natural defenses.

My Forest Bathing Bucket List in Japan
With so many stunning forests across Japan, it’s no surprise that the country is an ideal place to experience shinrin-yoku. Here are some of my top picks for forest bathing destinations. (Of course, there are so many more too!)

Home to ancient cedar forests, Yakushima’s mystical atmosphere makes it a top destination for forest bathing. Some trees here are over 1,000 years old, creating an awe-inspiring natural setting.
