Exploring 18 Benefits of Forest Bathing: The Healing Power of Nature

The gentle rustling of leaves, the earthy scent of the forest floor, and the dappled sunlight filtering through the canopy – these are the soothing elements of nature that have long captivated humans. In recent years, a Japanese practice known as forest bathing, or “Shinrin-yoku,” has gained global attention for its remarkable health benefits.

Forest bathing isn’t about hiking or exercising in the woods. Instead, it’s a mindful immersion in nature, using all our senses to connect with the forest environment. This practice, which originated in Japan in the 1980s, has since become a cornerstone of preventive healthcare and healing in Japanese medicine.

As our lives become increasingly urban and digitally connected, the importance of reconnecting with nature has never been more apparent. Forest bathing offers a simple yet profound way to enhance both physical and mental well-being. In this post, we’ll explore the science behind this therapeutic technique and discover how spending time in the woods can rejuvenate the mind, body, and spirit.

What is Forest Bathing?

Forest bathing, or Shinrin-yoku, is more than just a walk in the woods. It’s a practice of immersing oneself in the forest atmosphere, engaging all five senses to connect deeply with nature. Unlike hiking or other outdoor activities that focus on reaching a destination or achieving physical fitness, forest bathing emphasizes simply being present in nature.

The practice involves:

1. Slowing down and moving mindfully through the forest
2. Breathing deeply and consciously
3. Observing the surroundings with all senses – sight, sound, smell, touch, and even taste
4. Sitting or lying down to fully experience the forest environment
5. Leaving behind technology and other distractions

Key principles of forest bathing include:

• Mindfulness: Staying present and aware of your surroundings and sensations
• Non-judgment: Accepting thoughts and feelings without criticism
• Openness: Being receptive to the healing elements of nature
• Gratitude: Cultivating appreciation for the natural world

Forest bathing can be practiced alone or with a guide, and sessions typically last anywhere from 20 minutes to several hours. The goal is not to cover a certain distance or reach a specific location, but rather to immerse oneself fully in the forest atmosphere.

The Science Behind Forest Bathing

While the calming effects of nature have been intuitively understood for centuries, modern research is now providing scientific evidence for the health benefits of forest bathing. Here are some key areas where science is shedding light on this practice:

Phytoncides and Immune Function:

Trees and plants emit aromatic compounds called phytoncides, which are essentially their natural defenses against insects and bacteria. When humans inhale these compounds, it can lead to increased activity of natural killer (NK) cells, a type of white blood cell that helps fight off infected or tumor cells. Studies have shown that even a short period of forest bathing can increase NK cell activity for up to 30 days.

Dr. Qing Li, a prominent researcher in forest medicine, has extensively studied the impact of phytoncides on the immune system. He found that spending time in forests significantly increases the activity and number of Natural Killer (NK) cells, which play a crucial role in the body’s defense against tumors and viruses. According to Dr. Li, “The increased NK activity lasted for more than 30 days after a forest bathing trip, suggesting that a monthly trip would maintain a higher level of NK activity”

Impact on Stress Hormones:

Research has demonstrated that spending time in forests can significantly reduce cortisol levels, the body’s primary stress hormone. Lower cortisol levels are associated with reduced stress, improved mood, and better overall health.

A study in 2023¹The Effects of Dynamic and Static Forest Bathing (Shinrin-yoku) on Physiological and Psychological Health in Males and Females found that “dynamic and static forest bathing demonstrate positive impacts on human physical and mental health, although static forest bathing shows more pronounced effects on physiological health, while dynamic forest bathing shows greater effects on mental health.”

The study also found that forest bathing had favorable positive benefits on all genders. However, it particularly increased the psychological well-being of males and the physiological well-being of females.

Cardiovascular Effects:

Forest environments have been shown to lower both heart rate and blood pressure. This effect is attributed to the calming influence of nature and the increased parasympathetic nervous system activity (rest and digest) that occurs during forest bathing.

Dr. Gregory Bratman, an environmental psychologist at the University of Washington, has studied the impact of nature on human well-being. He states, “Exposure to natural environments can reduce physiological stress, lower blood pressure, and decrease heart rate, which are crucial for cardiovascular health​”. Furthermore, a review in Nature Reviews Cardiology²Nature and human well-being: The olfactory pathway highlights that spending time in natural settings can mitigate the harmful effects of air pollution on cardiovascular health, reducing the risk of heart diseases​

Nervous System Influence:

Forest bathing appears to decrease activity in the sympathetic nervous system (fight or flight) while increasing parasympathetic nervous system activity. This shift promotes relaxation, reduces stress, and may contribute to improved sleep and overall well-being.

Dr. Peter James from the Harvard T.H. Chan School of Public Health emphasizes the mental health benefits of nature exposure. He explains, “the ability to recover from stress is better in natural settings, because that’s where we are meant to be. Just the idea of getting out, being in nature, looking at a tree—the theory is that this helps you to recover from stress, improves your mental health, and improves cognition. It’s just a direct pathway.​”

His research suggests that these benefits are due to the calming effects of nature, which can lower levels of the stress hormone cortisol and promote relaxation.

Air Quality and Respiratory Health:

Forests, especially those with diverse plant life, can improve air quality by filtering pollutants and increasing oxygen levels. This can lead to better respiratory function and overall health, particularly for those coming from urban environments.

Attention Restoration:

Nature environments, including forests, have been found to improve cognitive function, particularly in areas of attention and focus. This is thought to be due to the “soft fascination” that nature provides, allowing our directed attention abilities to rest and recover.

These scientific findings help explain why many people report feeling refreshed, calm, and invigorated after spending time in nature. As research in this field continues to grow, it’s likely we’ll uncover even more ways in which forest bathing benefits our health.

Mental Health Benefits Of Forest bathing

Forest bathing offers a wide range of mental health benefits, making it an increasingly popular practice for those seeking natural ways to improve their psychological well-being. Here are some key mental health benefits:

1. Stress Reduction and Relaxation:

One of the most significant benefits of forest bathing is its ability to reduce stress. The natural environment, combined with mindful practices, helps lower cortisol levels and promotes a sense of calm. Many participants report feeling more relaxed and at ease after a forest bathing session.

The mental health benefits of forest bathing are well-documented. Dr. Qing Li notes that spending time in forests can reduce stress, anxiety, depression, and anger while enhancing overall mood and well-being. After years of careful study, Li says that “spending time in a forest can reduce stress, anxiety, depression, and anger; strengthen the immune system; improve cardiovascular and metabolic health; and boost overall well-being”​

2. Improved Mood and Decreased Depression Symptoms:

Exposure to nature, particularly in a forest setting, has been linked to improved mood and reduced symptoms of depression. The combination of physical activity, even if minimal, and connection with nature can boost serotonin levels, contributing to a more positive outlook.

In June 2019 a comparative study investigated the physiological and psychological effects of “forest bathing”³A comparative study of the physiological and psychological effects of forest bathing (Shinrin-yoku) on working age people with and without depressive tendencies on people of a working age with and without depressive tendencies. They conducted physiological measurements and psychological surveys before and after forest bathing with subjects who participated in day-long sessions of forest bathing, at a forest therapy base located in Hiroshima Prefecture.

The findings demonstrate significant positive effects on mental health, especially in those with depressive tendencies.

3. Enhanced Cognitive Function and Creativity:

Time spent in nature has been shown to improve various aspects of cognitive function, including:

• Attention span and focus
• Problem-solving abilities
• Working memory Additionally, the peaceful environment of the forest can spark creativity and inspire new ideas.

4. Increased Mindfulness and Present-Moment Awareness:

Forest bathing encourages participants to engage fully with their surroundings, promoting mindfulness. This practice of being present can help reduce rumination on past events or anxiety about the future, leading to a greater sense of overall well-being.

5. Reduced Anxiety:

The calming effects of nature can significantly reduce feelings of anxiety. The rhythmic sounds of nature, such as rustling leaves or flowing water, can have a soothing effect on the nervous system.

“The intent of forest bathing is to put people in touch with present-moment experience in a very deep way,” explains Cleveland Clinics Susan Albers, PsyD, a clinical psychologist. “The sights, sounds and smells of the forest take us right into that moment, so our brains stop anticipating, recalling, ruminating and worrying.”

6. Improved Self-Esteem:

Connecting with nature can foster a sense of belonging to something larger than oneself, which can boost self-esteem and self-worth. Sean Gunderson, founder of “the Healthy Pace” says “Natures impact on self-esteem lies in its ability to foster a sense of accomplishment. Whether conquering a challenging trail or finding peace beneath the shade of a tree, each step and every breath resonates with profound achievement.”

7. Enhanced Emotional Regulation:

Regular practice of forest bathing can help individuals develop better emotional regulation skills, making it easier to manage stress and emotional challenges in daily life. One study⁴The effects of forest bathing on self-criticism, self-compassion, and self-protection: A systematic review in July 2024 found that exposure to nature in the form of a forest can reduce harmful psychological states including self-criticism, rumination, anxiety, and depression while increasing beneficial psychological states such as self-compassion, introspection, and mindfulness.

8. Social Connection:

While often practiced individually, forest bathing can also be a group activity, promoting social connections and reducing feelings of isolation.

Jessica E. Schiff, from the University of Oxford, in her review on the associations between nature exposure and health, states⁵Associations between Nature Exposure and Health: A Review of the Evidence, “There is strong evidence that regular exposure to green spaces can improve cognitive function, enhance physical activity, and decrease the risk of chronic diseases such as cardiovascular and respiratory conditions”​

The review also supports the idea that nature provides opportunities for social engagement and physical activity, both of which are essential for maintaining good health.

Forest Bathing Physical Health Benefits

While the mental health benefits of forest bathing are well-documented, the practice also offers numerous physical health benefits. Here’s an overview of how spending time in the forest can improve your physical well-being:

9. Enhanced Immune System Function:

As mentioned earlier, phytoncides released by trees can increase the activity of natural killer cells in our bodies. This boost to the immune system can help fight off infections and potentially reduce the risk of certain cancers.

10. Improved Cardiovascular Health:

According to Dr. Qing Li’s research, exposure to phytoncides can lower blood pressure and heart rate. These findings are supported by other studies, which show that the forest atmosphere, rich in oxygen and phytoncides, helps reduce physiological stress and promote cardiovascular health

Forest bathing has been shown to have positive effects on heart health:

• Lowered blood pressure
• Reduced heart rate
• Decreased risk of heart disease

These benefits are attributed to the stress-reducing effects of nature and the gentle physical activity involved in forest bathing.

11. Better Sleep Quality:

Exposure to natural environments, especially forests, can help regulate circadian rhythms. This, combined with the stress-reducing effects of forest bathing, can lead to improved sleep quality and duration.

12. Increased Energy Levels:

Many people report feeling more energized after spending time in nature. This could be due to a combination of factors, including improved oxygen intake, reduced stress, and the rejuvenating effects of disconnecting from technology.

13. Improved Respiratory Function:

Forests typically have cleaner air with higher oxygen content compared to urban environments. Regular forest bathing can lead to improved lung function and may be particularly beneficial for those with respiratory conditions.

Jonathan Williams, a researcher at the Max Planck Institute for Chemistry, has explored how the smells of nature benefit our health. He notes, “Natural VOCs (volatile organic compounds) released by plants can have a significant impact on human well-being, potentially reducing stress and promoting a sense of relaxation.” This insight underscores the importance of the sensory experience in nature, where the smell of plants and trees plays a vital role in enhancing health benefits.

14. Weight Management:

While not a high-intensity workout, the gentle walking involved in forest bathing can contribute to weight management when practiced regularly. Additionally, stress reduction can help prevent stress-related overeating.

15. Lowered Blood Sugar Levels:

Some studies have shown that forest bathing can help lower blood glucose levels, which could be beneficial for people with or at risk of diabetes. One study discovered that people with diabetes who engaged in nine forest bathing and walking sessions over a span of six years experienced a decrease in their blood glucose levels.

The patients walked either 3 or 6 kilometers in the forest, depending on their health and physical condition, leading to a reduction of 70–74 milligrams per deciliter in their blood glucose levels post-walk. Another study revealed that the average blood glucose level of participants dropped from 179 milligrams per deciliter to 108 milligrams per deciliter following forest walking.

16. Reduced Inflammation:

The anti-inflammatory effects of certain organic compounds found in forest air may help reduce chronic inflammation, which is linked to various health issues. Forest bathing helps reduce inflammation due to its gentle physical activity that stimulates the release of myokines in muscles.

The plants in the forest, such as conifers, release compounds like alpha-pinene and beta-pinene, which also contribute to reducing inflammation. Studies show that these compounds can inhibit the production of inflammatory cytokines like IL-6 and TNF-a. This reduction in cytokine production helps alleviate joint stiffness and inflammation.

17. Improved Skin Health:

The humidity in forests can be beneficial for skin health, potentially improving conditions like eczema or dry skin. Elevated humidity levels in the air in humid weather conditions can prevent your skin from becoming dry. For those with normal or dry skin, increased humidity can contribute to softer, more supple, and nourished skin when compared to skin in a drier environment.

18. Enhanced Sensory Perception:

Regular practice of forest bathing can lead to improved sensory awareness, benefiting overall physical coordination and balance. Removing yourself from the sterile conditions of the gym also helps. When you are walking a trail and immersed in nature, the uneven terrain, ground conditions and potential trip hazards ensure that you are mentally focused and giving all of your muscles a great workout.

It’s important to note that while forest bathing can offer these physical health benefits, it should be seen as a complementary practice to regular medical care and a healthy lifestyle, not a replacement for them.
