Introduction[edit | edit source]

Nature Therapy (also known as ecotherapy and forest therapy) is an overarching term to describe the use of nature or natural elements to improve mental and /or physical health.[1] According to the The International Nature and Forest Therapy Alliance (INFTA), forest therapy "an evidence-based public health practice. Guided Forest Therapy walks combine a specific blend of complementary physical and mental exercises in suitable forest surroundings leading to a lower heart beat, blood pressure and stress levels while, at the same time, the immune system, breathing and the overall physical and mental fitness and agility are strengthened."[2]

Being in nature has beneficial effects on our health. This has been commonly known for centuries and is cornerstone for many "traditional" or "folk" medicine practices. However the healing power and beneficial effects of nature have become the focus of scientific research within the last few decades. Following a global movement towards cities which disconnects us from nature, isolation following the COVID-19 pandemic, and the ever present climate crisis may explain the novelty of this emerging focus in research.

Nature Therapy[edit | edit source]

Add overview of nature therapy

Common categories of nature therapy with descriptions and links In 2007, the research group "Forest medicine Study Group" was formally established in Japan. The group has since then led multiple research on the physiological and psychological effects of forests on human health. There is now research emerging from across the globe, including North America and Europe. Outdoor and nature guides are being trained to take the roles of nature therapy guides, therapists and doctors of medicine are using it as a tool or prescribing it to their patients to complement treatments. Nature is also being "brought indoors" or recreated virtually, to access to some of the benefits observed and studied in actual natural environments.

Shinrin-Yoku[edit | edit source]

Literally "forest bathing", the practice has been integrated to the Japanese health care system since 1982 with the aim to promote wellness and disease prevention, aiming particularly for workers' stress management. It consists of simply "taking in" the forest environment through all five senses and paying close attention to those. These videos provide further details on how it is practiced.

Physiological Effects[edit | edit source]

As of now, evidence surrounding the physiological effects of spending time in the forest is mainly connected to cardiovascular and immunological systems. Quantitative data was gathered mostly in Asian countries and with healthy populations, stroke patients and people with a diagnosis of hypertension. [5]

Cardiovascular[edit | edit source]

Nature and Forest Therapies have been shown to reduce overall blood pressure, and lower the heart rate, while activating the parasympathetic nervous system and reducing the sympathetic nervous system. [6]

Immune system[edit | edit source]

By acting on the autonomous nervous system, Nature Therapy can therefore benefit the immune system directly. As we know, the immune response is at its best when the body is relaxed and resting, which is why any practice that may reduce stress and facilitate relaxation is beneficial for the immune system. Furthermore, certain chemical compounds present in the forest air would have a direct effect on the immune system.[7]

Phytoncides and NK cells[edit | edit source]

Phytoncides, oils that trees emit to protect themselves from pathogens and parasites, have been shown to have a direct effect on the activity of NK (natural killer) cells in the body. NK cells are responsible for identifying and destroying potentially harmful organisms that enter the bloodstream. Higher activity of those cells means increase immune defense.[8][9][10]

Stress[edit | edit source]

Spending time in the forest has been shown to diminish the cortisol levels in the body and therefore reduce physiological stress. [11]

Psychological Effects[edit | edit source]

Nature therapy has been shown to reduce depression and anxiety, as well as affecting on the mood.[12]

Forest as Clinical Environment[edit | edit source]

As the benefits of carrying therapy sessions in the forest or other natural environments, the use of virtual reality or the presence of plants inside clinical spaces have proven equally effective on certain levels. Since it is not always possible to carry out therapy sessions in natural spaces, those alternatives can be useful in hospitals or for patients who are unable to access such spaces. [13] [12] The use of essential oils has also shown to have direct, beneficial effects on the mood and stress response of hospital workers. These oils contain the Phytoncides molecules (as described earlier), same effects are observed on the immune system and anxiety levels. [14][9]
