Nature-based Activity is Effective Therapy for Anxiety and Depression, Study Shows

A prescription of gardening an allotment in the UK has shown promise as a means of improving health and well-being outside of conventional medical treatments. 

Green social prescribing is a practice whereby a healthcare professional refers a patient to community-based nature activities to help improve health and well-being beyond medical treatments. Currently these programmes are in a testing phase, but evidence is now pointing to the need for investment in this area to make it an additional option for patients across the country.

More than 220 participants were included in the programme, and their mental health status was evaluated before and after exposure to an organised programme of nature-based activities, such as horticultural and care farming, sport and exercise, and outdoor mindfulness and craft-based activities.

The majority of participants took part in the programme weekly between one and four weeks, five to eight weeks, and others between nine and 12 weeks.  The team used the Office of National Statistics  measures of personal well-being, as well as the hospital anxiety and depression scale (HADS) to understand if participants had made improvements.

Horticulture

Across the board, participants reported improvements in well-being and mental health. But participants in longer programmes – typically nine to 12 weeks – or took part in activities related to horticulture and care farming, showed greater improvements in mood and anxiety levels compared with those involved in shorter programmes – one to four weeks – or in activities such as outdoor crafts, creative and mindfulness-based sessions, or sport and exercise.

The signs of improvement were similar to those seen in short-term cognitive behavioural therapy (CBT), where someone might meet one-to-one with a therapist over a period ranging from six weeks to a year or more.

Professor Peter Coventry, Director of the University’s Mental Health and Addiction Research Group, said: “We have known for some time that nature has a positive impact on health and wellbeing, but in more recent years, a stronger evidence-base has grown that proves this to be true for mental health in particular.

“The fact that activities such as gardening, tending allotments, and care farming had the most impact on the participants in our study, demonstrated that it is not just about being passive in nature, but connecting with it in a meaningful way.  

“There is also something to be said for connecting with nature in the company of other people who live in the same place as you.  Anxiety and depression can often be born out of loneliness and feelings of disconnectedness, so it makes sense that taking part in shared activities close to home  – especially those that involve caring for and improving your local environment – can help lift mood and reduce anxiety.”

All ages

The study showed that these positive impacts were seen in all ages, which ranged from age 18 to age 85, and across genders.  Researchers are now calling for more investment to be made to support these community activities and the employment of green social prescribers that GPs and other health and social care professionals can refer their patients to.

Trish Darcy, research associate from the University’s Mental Health and Addiction Research Group, said: “This intervention might not work for everyone, but through an initial exploratory conversation a social prescriber will discuss with a patient or user of the service if nature-based activities would be suited to them, and for that choice to happen we need more investment to support these community-based activities”. 

“In our study 65% of participants were from low socioeconomic groups and we now know that not only can it help improve their mental health, but participation was high for  horticultural based activities in particular, meaning that not only is it good for the individual, but for the local community environment too.”

Test and learn

The evaluation, published in the journal Health & Social Care in the Community, was conducted in partnership with The HEY Smile Foundation and NHS Humber and North Yorkshire Integrated Care Board (ICB).

Dr Hannah Armitt a Clinical Psychologist and Clinical Lead for the Humber and North Yorkshire ‘test and learn’ programme said: “The research conducted in our region has the potential to enhance service delivery by connecting statutory services with local providers of nature based and outdoors activities. 

“It is important to evidence the potential of green space and nature to ensure clinicians and patients alike can harness the benefits of this wonderful free natural resource we have in abundance in Yorkshire and Humber.”

Positive outcomes

Anthony Hurd, Humber and North Yorkshire Green Social Prescribing Programme Manager, said “This work has not only shown the positive outcomes that nature-based activities have on mental health, it has also highlighted the role that community-based organisations play in supporting the health and wellbeing of communities. 

“As healthcare begins to move more into the community, and with a focus on prevention, the community-based organisations delivering activities such as gardening, care farming and walking groups need to be recognised as key players in our national health service and be resourced appropriately.”

Nature Relieves Physical Pain Signals in the Brain

This effect even occurs with virtual nature – such as nature videos

In a new study, an international team of neuroscientists led by the University of Vienna has shown that experiencing nature can alleviate acute physical pain. Surprisingly, simply watching nature videos was enough to relieve pain. Using functional magnetic resonance imaging, the researchers found that acute pain was rated as less intense and unpleasant when watching nature videos – along with a reduction in brain activity associated with pain. The results, published in Nature Communications, suggest that nature-based therapies can be used as promising complementary approaches to pain management.

“Pain processing is a complex phenomenon” explains study lead and doctoral student Max Steininger from the University of Vienna. In order to better understand it and identify treatment options, Steininger and his colleagues investigated how nature exposure influences pain: participants suffering from pain were shown three types of videos: a nature scene, an indoor scene, and an urban scene. The participants rated the pain while their brain activity was measured using functional magnetic resonance imaging. The results were clear: when viewing the nature scene, the participants not only reported less pain but also showed reduced activity in brain regions associated with pain processing.

By analyzing the brain data, the researchers showed that viewing nature reduced the raw sensory signal the brain receives when in pain. “Pain is like a puzzle, made up of different pieces that are processed differently in the brain. Some pieces of the puzzle relate to our emotional response to pain, such as how unpleasant we find it. Other pieces correspond to the physical signals underlying the painful experience, such as its location in the body and its intensity. Unlike placebos, which usually change our emotional response to pain, viewing nature changed how the brain processed early, raw sensory signals of pain. Thus, the effect appears to be less influenced by participants’ expectations, and more by changes in the underlying pain signals,” explains Steininger.

Claus Lamm, head of research in the group, adds: “From another ongoing study, we know that people consistently report feeling less pain when exposed to natural environments. However, the underlying reason for this has remained unclear – until now. Our study suggests that the brain reacts less to both the physical source and the intensity of the pain.”

The current study provides important information on how nature can help alleviate pain and highlights that nature-based therapeutic approaches can be a useful addition to pain treatment. The fact, that this effect was observed by simply watching nature videos suggests that taking a walk outdoors may not be necessary. Virtual nature – such as videos or virtual reality – appears to be effective as well. This opens up a wide range of possible applications in both the private and medical sectors, providing people with a simple and accessible way to relieve their pain.

The study was conducted at the University of Vienna in collaboration with researchers from the Universities of Exeter and Birmingham (UK) and the Max Planck Institute for Human Development.

Greenspaces in Hospitals Calm Patients and Visitors

On By ModernMedia

It can be stressful and time-consuming for patients and visitors to become accustomed to navigating large, unfamiliar hospitals, and so an architecture researcher tested a simple remedy: to let nature in with the use of indoor greenspaces and large windows.

Research conducted by West Virginia University’s associate professor Shan Jiang showed that introducing nature into large hospitals can humanise the institutional environment and reduce the stress of patients, visitors and healthcare providers.

Prof Jiang made use of immersive virtual environments for a controlled experiment that asked participants to complete various wayfinding tasks in a simulated hospital.

Though participants saw the same layout, one group encountered large windows and nature views among the corridor walls. The control group meanwhile saw solid walls without any daylight or views of nature, more like a typical modern hospital. Participants in the greenspace group used shorter time and walked less distance to complete wayfinding tasks.

“In terms of spatial orientation and wayfinding, window views of nature and small gardens can effectively break down the tedious interiors of large hospital blocks,” Prof Jiang said, “and serve as landmarks to aid people’s wayfinding and improve their spatial experience.”

In the greenspace group, participants’ mood states, particularly anger and confusion, were also found to be “significantly relieved”.

Prof Jiang’s findings are published in the Health Environments Research and Design Journal.

Based on prior research, it’s estimated that a patient or hospital visitor must go through at least seven steps in the wayfinding process to arrive at the final destination. WVU’s Center for Health Design cites wayfinding issues as an environmental stressor and a concerning topic in healthcare design.

Prof Jiang said that she was prompted to do the study by those factors, coupled with her own personal experiences (her family members have worked in healthcare) and others’ accounts of feeling lost in hospitals.

“Large hospitals can be visually welcoming but the functionality and internal circulation are indeed complex and confusing,” she said.

Greenspaces positioned at key decision points, such as main corridors or junctions, can help improve navigation.

With a background in landscape architecture, Jiang has been interested in the immediate surroundings of people in a smaller scope, particularly the indoor-outdoor relationship and the boundaries between architecture and landscapes.

Gardens and plants also tend to have strong therapeutic effects on people, she found.

“You may explain such therapeutic effects from multiple perspectives: people’s colour/hue preferences tend to range from blue to green, nature and plants are positive distractions that could restore people’s attentional fatigue, and human beings could have developed genetic preference of greenery from evolutionary perspectives,” Prof Jiang said. “All mechanisms together contribute to the positive experience when looking at gardens and nature views.”

Prof Jiang noted that many European hospitals have successfully integrated “hospital in a park” concepts. In the United States, the Lucile Packard Children’s Hospital Stanford in California has patios and window nooks in every patient room, and most rooms have direct views of a large healing garden, she said. The Alder Hey Children’s Hospital in the UK was literally built in a park.
