Shinrin-Yoku: An expert guide to combat mental stress with proven Japanese trick

Can forests have a soothing impact on our mental well-being? The answer lies in experiencing it. The sounds of birds chirping, the rustling of leaves and the absence of urban noise seem utopic in the bustling metropolis of Mumbai. However, these elements constitute a rising wellness retreat known as "Shinrin-Yoku", a practice that lets urban dwellers sign off from the city to immerse in nature.

Shinrin-Yoku, which translates into "forest bathing" or "taking in the forest atmosphere," was developed in the 1980s. The origins of Shinrin-Yoku can be traced back to the post-industrial revolution in Japan. During that era, there was a growing recognition of poor mental health caused by booming urbanisation, work pressure and disconnection from nature amongst Japanese people, informs Dr. Manoj Kutteri, Medical Director at Atmantan Wellness Centre.

Origins of Shinrin-Yoku

In the early eighties, Japan was undergoing rapid industrialization and development, leading to a rise in urban lifestyles and technological advancements. This shift towards urbanization resulted in a fast-track life that became tedious to keep up with. Consequently, it resulted in increased stress, sedentary lifestyles and limited access to natural environments for the Japanese.

In response to these challenges, the Japanese Ministry of Agriculture, Forestry and Fisheries initiated a research program in 1982 to explore the potential health benefits of spending time in forests. The program aimed to promote the concept of Shinrin-Yoku as a preventive health strategy and to encourage people to reconnect with nature.

They monitored and examined individuals' physiological reactions, such as blood pressure, heart rate and cortisol levels, before and after they spent time in the woods. The findings repeatedly showed positive effects on mental and physical well-being, such as reduced stress, lower blood pressure, improved mood and immune system performance.

Based on these findings, Shinrin-Yoku gained popularity as a recognized form of therapy and was integrated into Japan's public health initiatives. It became a prescribed activity and a part of preventive healthcare measures, with designated forest therapy trails and certified forest therapy guides.

The science behind Shinrin-Yoku

The natural therapeutic properties of Shinrin-yoku (forest bathing) have been studied scientifically, particularly in Japan. Scientists conducted studies that revealed how forests release organic substances known as phytoncides. These substances are essential oils generated by trees and plants that are antimicrobial.

Trees absorb pollutants and act as natural air filters, releasing oxygen and improving air quality. Additionally, forests harbour plenty of negative ions, which are charged particles prevalent near running water, greenery and natural setting. These ions are also common in forests and have been linked to better moods, lower stress levels and enhanced emotions of well-being.

Humans have a natural affinity for nature, which is known as biophilia. Shinrin-Yoku allows people to reconnect with nature and realise their biophilic needs. Also engaging our senses in nature, such as feeling the textures of tree bark or listening to birdsong, elicits good emotional responses and promotes a sense of connection with the natural world.

Physiological and psychological benefits of forest bathing

Kutteri reveals how Shinrin-Yoku impacts our mental well-being. He lists down the following effects of forest bathing:

Reduced stress

Spending time in nature, especially in lush green forests, significantly reduces stress levels. The calming sounds, fresh air and serene surroundings help promote relaxation and reduce the production of stress hormones like cortisol.

Improved immune system function

Phytoncides, which are natural oils emitted by trees, are inhaled during forest bathing. These substances have been found to enhance the activity of natural killer cells and increase the production of anti-cancer proteins, thereby boosting the immune system.

Enhanced mood and mental well-being

Forest bathing has a positive impact on mental health, promoting a sense of calmness, improved mood and increased happiness. It has been associated with reduced symptoms of anxiety, depression and other mental health disorders.

Increased energy and vitality

Spending time in nature revitalizes the body and mind. The combination of fresh air, natural light and the peacefulness of the forest can improve energy levels and combat fatigue.

Lower blood pressure and heart rate

Forest bathing has been linked to a decrease in blood pressure and heart rate. This reduction in physiological stress markers can contribute to improved cardiovascular health and a lower risk of heart disease.

Improved sleep quality

Regular exposure to nature through Shinrin-Yoku can help regulate sleep patterns and improve the quality of sleep. The relaxation and reduced stress associated with forest bathing can lead to more restful and rejuvenating sleep.

Increased focus and creativity

Immersing oneself in nature has proven to enhance cognitive function, including improved concentration, focus and problem-solving skills. It can also stimulate creativity and boost inspiration.

Connection with nature

Shinrin-yoku provides an opportunity to connect with the natural world and develop a deeper appreciation for the environment. This connection can lead to a greater sense of purpose, environmental stewardship and a desire to protect and preserve natural spaces.

Forest bathing has been shown to improve cognitive performance, including attention, memory and creativity. Being in nature allows for a cognitive respite from intellectually taxing duties as well as the restoration and regeneration of cognitive resources. It also increases happiness and well-being.

Practicing Shinrin-Yoku in metro cities

Urban dwellers are inflicted with various issues of stress and hypertension. According to the National Family and Health Survey's (NFHS) latest report, 21 percent women and 24 percent men of age 15 years and above have hypertension. Around 40 percent of adults of age 15 years and above are pre-hypertensive.

While Mumbai is a busy city, there are still possibilities to engage in forest bathing or nature immersion in and around the city. A good example is the Sanjay Gandhi National Park near Borivali. Spending time in the forest, walking through the trails, observing the natural flora and fauna and relaxing in the tranquil setting can have a therapeutic impact on those dealing with stress.

Mumbai's urban parks and gardens also provide a good escape to immerse in leisure and nature appreciation. Popular attractions include Hanging Gardens, Horniman Circle Garden and Five Gardens. Other places such as Karnala Bird Sanctuary, Tungareshwar Wildlife Sanctuary and the hills of Matheran provide opportunities to reconnect with nature while enjoying breathtaking views.

Tips to practice forest bathing in metro cities

While forest bathing in a metro or urban area may not provide the same level of natural immersion as being in a dense forest, you can still benefit from it. Spending time in the parks, strolling, sitting, or lying down, taking in the sights, sounds, and fragrances of nature helps in stimulating all five senses. Another option is to take some time out at rooftop gardens or balconies.

One can create their own green zone by building a small place to relax surrounded by potted plants, flowers, or perhaps a mini herb garden. This area can be utilized for relaxation, meditation, or simply unwinding amongst natural elements.

Treating burn-outs with forest bathing

For those experiencing burnout from their personal and professional hustles, Shinrin-Yoku comes as a respite. Forest bathing has shown to successfully lessen stress levels. Spending time in nature, away from the stresses of work, allows you to detach and unwind. The sights, sounds, and fragrances of the forest can assist in relaxing your nervous system and lessening stress chemicals like cortisol.

The forest's tranquil and peaceful atmosphere can help alleviate the mental and emotional exhaustion associated with burnout. It also promotes mindfulness and the ability to be present in the moment. You can focus on your environment, engage your senses, and let go of work-related thoughts by immersing yourself in nature.

One aspect to keep in mind is that forest bathing is not a quick fix for work fatigue. It supplements a comprehensive strategy for burnout management, which may also include setting boundaries, finding support, and making changes.

How can it help in reducing stress and anxiety?
Shinrin-yoku can be extremely beneficial in terms of stress and anxiety reduction. Kutteri suggests seeking out regions that provide a serene and tranquil setting where one may immerse themselves in nature. Turning off one's personal gadgets to reduce distractions is a failsafe way to truly immerse in the woodland bathing experience.

Disconnecting from technology allows you to be present and really appreciate nature's calming influence. Focus on activating your senses when you enter the forest or green place. Inhale deeply and take deep breaths. Use mindfulness or meditation techniques to focus on your breath or body sensations. Allow any worry or anxiety to dissipate from your mind and body as you immerse yourself in the calm and tranquility of the forest.

Does it enhance the level of fitness or is it just a psychological remedy?
Shinrin-yoku is not primarily a fitness activity. It instead emphasises on being immersed in nature and receiving the mental and emotional benefits that come with it. While forest bathing is not a strenuous form of exercise, it frequently incorporates light walking or movement in a natural setting.

Walking on uneven terrain and traversing paths can provide your muscles, joints, and the cardiovascular system a light exercise. This modest physical activity can help to enhance overall fitness, especially for those who are less active or have mobility issues.
