In modern society, stress reduction in the workplace is a pressing issue. While it has been commonly assumed that plant life is soothing to those required to regularly face stressful or mundane situations, this study scientifically verifies the degree of psychological and physiological impact induced by indoor plants.
A study out of the University of Hyogo in Awaji, Japan, details the stress-reducing benefits to office workers that even a small plant situated within easy viewing can impart.
Masahiro Toyoda, Yuko Yokota, Marni Barnes, and Midori Kaneko explored the practical use of indoor plants to boost mental health among employees typically removed from exposure to healthy green environments.
Their findings are illustrated in their article "Potential of a Small Indoor Plant on the Desk for Reducing Office Workers' Stress" published in the open access journal HortTechnology, by the American Society for Horticultural Science.
In modern society, stress reduction in the workplace is a pressing issue. While it has been commonly assumed that plant life is soothing to those required to regularly face stressful or mundane situations, this study scientifically verifies the degree of psychological and physiological impact induced by indoor plants. Rather than conducting experiments in a laboratory setting, the researchers calculated stress reduction on employees in real office settings.
Toyoda adds, "At present, not so many people fully understand and utilize the benefit of stress recovery brought by plants in the workplace. To ameliorate such situations, we decided it essential to verify and provide scientific evidence for the stress restorative effect by nearby plants in a real office setting."
Toyoda and his team investigated changes in psychological and physiological stress before and after placing a plant on the workers' desks. Sixty-three office workers in Japan were the participants of this study. The participants were directed to take a 3-minute rest while sitting at their desks when they felt fatigue.
There were two phases of the study: a control period without plants and an intervention period when the participants were able to see and care for a small plant. The researchers measured psychological stress in the participants using the State-Trait Anxiety Inventory. The ratio of the participants whose pulse rate lowered significantly after a 3-minute rest with interaction with their desk plant proved definitive.
The objective of this study was to verify the stress-reducing effect of gazing intentionally at a plant in a real office setting when a worker felt fatigue during office hours. Each plant used in the study was chosen and cared for by the worker. Both passive and active involvement with plants in the workplace were considered for their contribution to mitigation of stress and fatigue.
Participants were provided routine visual access to plants by having their choice of plant situated conveniently on their desks (a passive involvement with plants). They also had the opportunity to care for their plant (an active involvement with plants). Furthermore, the researchers considered that intentionally gazing at the plant was, though not involving physical movement, an active interaction with plants that office workers could do quickly and easily at their desks.
Participants were offered a choice of six different types of plants to keep on their desks: air plants, bonsai plants, san pedro cactus, foliage plants, kokedama, or echeveria. Each participant chose one of the six types of small indoor plants and placed it near the PC monitor on their desk.
The calming effects calculated during the study showed that anxiety decreased significantly from pre- to post-intervention. The results did not skew when looking at the data within the various age groups of the workers or with different plant selections. The researchers suggest that placing small plants within close sight contributed to psychological stress reduction across the board.
Toyoda and his team suggest for business owners that small indoor plants could be economical and helpful in efforts improve office conditions for employees. In addition, for growers of indoor plants and business owners of retail plant companies, the field of mental health for office workers could open up a new avenue of a promising market.

Reconnecting with nature key for the health of people and the planet
February 13, 2020
Science Daily/University of Plymouth
Researchers are the first to investigate -- within a single study -- the contribution of both nature contact and connection to human health, well-being and pro-environmental behaviors.
Individuals who visit natural spaces weekly, and feel psychologically connected to them, report better physical and mental wellbeing, new research has shown.
Alongside the benefits to public health, those who make weekly nature visits, or feel connected to nature, are also more likely to behave in ways which promote environmental health, such as recycling and conservation activities.
The findings of the study, published in the Journal of Environmental Psychology, indicate that reconnecting with nature could be key to achieving synergistic improvements to human and planetary health.
The study was conducted by researchers at the University of Plymouth, Natural England, the University of Exeter and University of Derby, and is the first to investigate -- within a single study -- the contribution of both nature contact and connection to human health, wellbeing and pro-environmental behaviours.
The findings are based on responses to the Monitor of Engagement with the Natural Environment (MENE) survey, commissioned by Natural England as part of DEFRA's social science research programme. The team looked at people's engagement with nature though access to greenspace, nature visits and the extent to which they felt psychologically connected to the natural world.
Lead author Leanne Martin, of the University of Plymouth, said: "In the context of increasing urbanisation, it is important to understand how engagement with our planet's natural resources relate to human health and behaviour. Our results suggest that physically and psychologically reconnecting with nature can be beneficial for human health and wellbeing, and at the same time encourages individuals to act in ways which protect the health of the planet."
Marian Spain, Chief Executive of Natural England added: "It's a top priority for Natural England to unlock the potential of the natural environment to help address the challenges we are facing as a society: poor physical health and mental wellbeing; the climate change crisis and the devastating loss of wildlife.
"These findings give vital new insights of the need to not just increase contact with nature, but about the sorts of experience that really help people build an emotional connection, which is key to unlocking health benefits as well as inspiring people to taking action to help their environment. We look forward to using the research as we work with our many partners to support more people from all walks of life to benefit from thriving nature."

How to consider nature's impact on mental health in city plans
July 24, 2019
Science Daily/University of Washington
Almost one in five adults in the U.S. lives with a mental illness. That statistic is similar worldwide, with an estimated 450 million people currently dealing with a mental or neurological disorder. Of those, only about a third seek treatment.
Interacting with nature is starting to be recognized as one way to improve mental health. A number of scientific studies have shown that nature experiences may benefit people's psychological well-being and cognitive function. But it has been difficult to find ways to quantify these benefits in a useful manner for cities or organizations that want to integrate nature to improve mental health.
Now, an international team led by the University of Washington and Stanford University has created a framework for how city planners and municipalities around the world can start to measure the mental health benefits of nature and incorporate those into plans and policies for cities and their residents. The study will appear July 24 in Science Advances.
"Thinking about the direct mental health benefits that nature contact provides is important to take into account when planning how to conserve nature and integrate it into our cities," said Greg Bratman, lead author and an assistant professor at the UW School of Environmental and Forest Sciences. "The purpose of this paper is to provide a conceptual model of one way we can start to think about doing this."
The study brought together more than two dozen leading experts in the natural, social and health sciences who study aspects of how nature can benefit human well-being. Their first step was to establish a baseline, collective agreement regarding the understanding of the impacts of nature experience on aspects of cognitive functioning, emotional well-being and other dimensions of mental health.
"In hundreds of studies, nature experience is associated with increased happiness, social engagement, and manageability of life tasks, and decreased mental distress," said senior author Gretchen Daily, faculty director at the Stanford Natural Capital Project. "In addition, nature experience is linked to improved cognitive functioning, memory and attention, imagination and creativity, and children's school performance. These links span many dimensions of human experience, and include a greater sense of meaning and purpose in life."
While this line of study is still emerging, experts agree that nature can reduce risk factors for some types of mental illnesses and improve psychological well-being. They also agree that opportunities for nature experiences are dwindling for many people around the world because of urban growth.
"For millennia, many different cultures, traditions, and religious and spiritual practices have spoken directly to our deep relationship with nature. And more recently, using other sets of tools from psychology, public health, landscape architecture and medicine, evidence has been steadily gathering in this emerging, interdisciplinary field," Bratman said.
The study outlines how city planners, landscape architects, developers and others could eventually anticipate the mental health impacts of decisions related to the environment.
Many governments already consider this with regard to other aspects of human health. For example, trees are planted in cities to improve air quality or reduce urban heat island effects, and parks are built in specific neighborhoods to encourage physical activity. But these actions don't usually directly factor in the mental health benefits that trees or a restored park might provide.
"We have entered the urban century, with two-thirds of humanity projected to be living in cities by 2050. At the same time, there is an awakening underway today, to the many values of nature and the risks and costs of its loss," Daily said. "This new work can help inform investments in livability and sustainability of the world's cities."
The research team built a conceptual model that can be used to make meaningful, informed decisions about environmental projects and how they may impact mental health. It includes four steps for planners to consider: elements of nature included in a project, say at a school or across the whole city; the amount of contact people will have with nature; how people interact with nature; and how people may benefit from those interactions, based on the latest scientific evidence.
The researchers hope this tool will be especially useful in considering the possible mental health repercussions of adding -- or taking away -- nature in underserved communities.
"If the evidence shows that nature contact helps to buffer against negative impacts from other environmental predictors of health, then access to these landscapes can be considered a matter of environmental justice. We hope this framework will contribute to this discussion," Bratman said. "Eventually, it could be developed and potentially used to help address health disparities in underserved communities."
