HARVARD BUSINESS REVIEW | Emma Seppala and Johann Berlin | Why You Should Tell Your Team to Take a Break and Go Outside
Wellness programs are becoming an integral priority for most human resource managers. After all, research shows that a happier workplace is more productive. To this end, workplaces are adding health-related perks from exercise rooms to yoga classes. Leaders participate in mindfulness and compassion trainings and are coached to learn emotional intelligence. However, there is one important wellness factor that many are forgetting even though it may be the most potent of all: access to green spaces.
Greenery isn’t just an air freshener that’s pleasant to look at, it can actually significantly boost employee well-being, reduce stress, enhance innovative potential, and boost a sense of connection.
Yet most of us don’t spend much time in nature. Richard Louv, author of the Nature Principal, argues that we’re collectively suffering from “nature-deficit disorder,” which hurts us mentally, physically, and even spiritually. Adding a little wilderness to your corporate offices may just be the smartest move you can do this year.
For one, exposure to green spaces profoundly enhances physical and mental well-being which is why corporations like Google prioritize biophilia as a core design principle. Studies are showing these interventions can reduce not just everyday stress but also boost general health. Taking walks in nature lowers anxiety and depression while boosting mood and well-being, a large-scale study showed. Exposure to more light can boost Vitamin D levels that are known to increase mood, especially in colder months.
Scientists are also exploring how exposure to nature might result in lower risk of depression, obesity, diabetes, and cancer. The immune system certainly receives a boost from stress-reduction, and even just the sounds of nature trigger a relaxation response in the brain. Exposure to natural environments lowers stress, including its physiological correlates the “stress hormone” cortisol, heart rate, and blood pressure. By boosting mood, natural environments may also decrease inflammation at the cellular level.
In short, even a small green intervention like having more plants in the office could significantly boost employee happiness, and we know that happiness is a powerful predictor of an organization’s success. Corporations can significantly reduce organizational health costs by introducing more green spaces and plants into an office space. As Florence Williams has exhaustively reviewed in her recent book The Nature Fix, “forest bathing” have become popular practices in many East Asian countries because the impact of even a few minutes of immersion in nature has measurable benefits not just for our psychological well-being but also our physical health.
Greener office environments can boost employee performance and decision-making. One study found that exposure to greenery through office plants boosted not just employee well-being but also productivity - by 15%! Lead researcher Marlon Nieuwenhuis concludes: “Our research suggests that investing in landscaping the office with plants will pay off through an increase in office workers’ quality of life and productivity.” For one, plants, natural environments and greener offices offer superior air quality which in turn strengthens employee cognitive function – allowing them to perform at their best.
Here’s why this may be the case:
Neurosciencist and founder of My Brain Solutions Dr Evian Gordon proposes that “the brain’s attunement to nature has a seminal evolutionary origin, beginning with the earliest species sensing and responding to their environment. Our ancestral hominids (australopithecus, homo habilis, and homo erectus) evolved in response to short-term survival pressures within the rhythms of nature.” Dr Gordon who has published more than 300 scientific papers draws upon insights from the world’s largest standardized brain function database, that shows the immediate and significant extent to which any sensory input creates changes in the brain and body. Stress impacts the heart’s rhythms, for example. Unnatural environments are a subtle form of distraction and stress to optimal brain processing. Natural environments have the opposite effect.
Moreover, research shows that exposure to a natural environment helps people be less impulsive (while urban settings do the opposite). In this particular study, participants were asked if they’d prefer to make $100 immediately or $150 in 90 days. Those who had either been in a natural environment (or simply looked at photos of a natural environment) were more likely to make the more rational and beneficial decision: wait for the $150. Such was not the case for those exposed to cityscapes. Exposure to nature may therefore foster boost superior decision-making which includes better foresight. Exposure to natural environments also strengthens attention and may even help strengthen memory.
Finally, we know that the #1 trait leaders look for in incoming employees is creativity, and exposure to natural environments dramatically improves our ability to think expansively and make superior decisions.
Being in nature is a core element of New York designer Joanne DePalma’s work, inspiring her most iconic designs, including the flagship store for Tiffany in Paris, and leading her to creative breakthroughs, including creating one of the world’s most sustainable carpets with Bently Prince Street. “Nature inspires my design and restores me,” she shares. “Whether I’m feeling stuck or exhausted during a long and grueling project, or just need some new ideas, a visit to the waterfront or Central Park gets me back to the source of my creativity. I find so many complex design solutions are hidden in nature.”
Nature can have a positive influence on workplace culture by strengthening employees’ values and leading to greater harmony and connection. Exposure to nature doesn’t just make you feel and think better, it also makes you behave better. People who’ve just walked out of a park or other natural environment are more likely to notice when others need help – and to provide that help. In line with these findings, researchers at the University of Rochester found that exposure to nature resulted in participants valuing community and connectedness over more superficial concerns like personal gain and fame. Participants also became more generous and willing to share with others.
As the lead author Netta Weinstein observes, “we are influenced by our environment in ways we are not aware of….to the extent that our links with nature are disrupted, we may also lose some connection with each other.” Given that there are fewer and fewer “human moments” in the workplace yet that employee well-being is in large part due to positive social connections with other people, embracing greener environments could be tremendously beneficial for a workplace. Other studies have confirmed that exposure to nature leads to less antisocial behavior and more social connection and harmony.
Even a very small exposure to nature – as little as five minutes – can produce dramatic benefits, especially when coupled with exercise like walking or running. In many of the studies mentioned above, the effect was observed after participants simply looked at pictures of nature (vs urban environments) for a few minutes or worked in an office with (or without) plants — easy touches to add to a work setting.
While creating a “green office” may seem daunting, it really isn’t. Here are some easy ways you can make your officer greener:
- Encourage your staff to have “walking meetings” outside.
- Encourage your staff to sit outside or in naturally lit areas on breaks or during lunch.
- Provide outdoor walking, meeting, and sitting spaces.
- If outdoor spaces are not available or you are in an urban environment, create an indoor garden in an atrium or, if space is at a premium, a vertical “green wall.”
- Light rooms with natural sunlight as much as possible. Open blinds and, if possible, windows to let in outside air and natural sounds.
- Display nature photography or artwork.
- Play nature videos or nature slides on your television or display screens.
- Place as many plants as you can prominently around the office (making sure a designated person takes good care of them).
- Move your office closer to a park or natural environment.
An increasing interest at Google and similar companies is to make green spaces that are also respectful of the natural environment as a habitat for local animals and plants. Not only are these companies promoting employee well-being, but also reducing their ecological footprint.
Even if your company’s management is unwilling or unable to do these things, you can try a few out yourself: a walking meeting with a colleague, taping a photo of your favorite nature scene to your cubicle, or listening to ambient nature sounds on your headphones. Remember the words of German poet Rainer Marie Rilke: “If we surrendered / to earth’s intelligence / we could rise up rooted, like trees.”
