In some of my earliest memories, I鈥檓 perched between two branches of a plum tree that grew in front of my house. To climb, I鈥檇 grip the lowest branches and stretch my foot as high as it would reach, pulling myself up to sit comfortably in my little throne of branches. There, I鈥檇 peer through the pale purple blossoms, across the sidewalk, admiring the tops of cars.

I don鈥檛 remember any fear鈥攋ust the scrape of callused feet on bark; the triumph of successfully hoisting my knee onto a branch; the comfort of my hands circling that final limb as I reached the perfect nestling spot.

Growing up with attention deficit hyperactivity disorder, I was anxious a lot. I procrastinated constantly because I didn鈥檛 know how to prioritize. I was worried I might be stupid because I couldn鈥檛 finish basic tasks. Sitting still in a circle was torture. But at the tops of familiar trees, seeing everything through a veil of leaves or delicious-smelling blossoms, I could make my brain stop spinning.

Even now, laundry stays in the washing machine for three days because I forget about it. I leave half-full glasses of water all over the house. Currently, I have 52 tabs open in three Chrome windows. The other day I went into my bedroom to get my phone charger but only managed to change my shirt. Spending time with plants is still my reset button.

In my quest for introspection and mental quiet time, trees have been my most stalwart allies.

Nature鈥檚 鈥渃ognitive restoration鈥�

Physical activity is known to help combat and prevent these disorders, but a walk down a busy traffic-filled street doesn鈥檛 cut it. A walk in the woods, however, works.

helps explain why.

Urban environments are overwhelming. City dwellers are constantly bombarded with complex sights, sounds, and smells. Researchers believe that this has a negative effect on , making us less able to cope with distractions. Captivating natural scenes, however, can .

Interestingly, some built environments can have the same effect. Cities that incorporate water, or 鈥�,鈥� are more restorative than those without. and countryside fit the bill because, like nature, they evoke a sense of 鈥渂eing away.鈥� are restorative because they provide an escape from the cacophony of urban life. These scenes all give one a sense of space鈥攐f .

The problem with urbanization

无码视频 than half of the world鈥檚 population, and counting, .聽People in cities run a than people in rural areas鈥�20 and 40 percent higher, respectively. We鈥檙e also more sedentary than ever, and .

Apartments, office buildings, subways, traffic-filled streets鈥攚e鈥檙e spending more and more time away from nature. Researchers estimate that if every city dweller spent just 30 minutes per week in nature, by 7 percent. Globally, that鈥檚 a whopping 21 million people. But for a busy city dweller, a visit to a beautiful monastery isn鈥檛 always feasible. We all have read about the benefits of 鈥渇orest therapy,鈥� but a half-day hike in the woods is a luxury many can鈥檛 afford.

The answer lies in incorporating green space into urban planning, weaving nature into the fabric of everyday city life.

To understand our fraught relationship with urban nature, consider the evolution of big cities. Urbanization exploded in the 1800s as more people left their rural homes to look for work. With the focus on high-level priorities such as sanitation, not to mention basic transportation and housing, green space just wasn鈥檛 considered sufficiently important for human welfare.

Kathleen Wolf, a social science researcher at the University of Washington, studies the human benefits of nature in cities.

With the industrial boom and huge population influx, rates of disease went up, she says, and we focused on clearing space for sanitary engineering systems. 鈥淲hat we think now is that, maybe, the pendulum went a little too far in removal of nature from cities.鈥�

Racial and class inequity in green space

Modern higher-income communities鈥攐ften predominately White鈥攈ave the time, influence, and financial resources to build green space and cultivate a sense of appreciation for urban nature, Wolf says. But poorer communities鈥攊ncluding some communities of color鈥攄on鈥檛 always have the same luxury.

鈥淭here are top-level priorities in communities of need with regard to health: crosswalks, sidewalks鈥攔eally fundamental needs鈥攁ssurance that people have housing. I would guess that if our cities could mobilize and satisfy those high-level needs, people in those communities would then begin to say, 鈥榃e have now a baseline quality of life; now [we can talk about] parks.鈥欌��

Yet these people need green space the most. People with less financial security often have more demanding lifestyles. 鈥淭hey may be working multiple jobs. They may be single parents. They may have inadequate support systems,鈥� Wolf says. 鈥淧eople in those situations 鈥� benefit even more from green space encounters.鈥�

Add to this the growing demands on our nation鈥檚 young adults鈥攅xpensive housing, out-of-control student loans, 鈥攁nd it鈥檚 easy to see the dire need for cities to address cognitive fatigue, especially in stressed and underserved populations.

Investing in 鈥済reen鈥�

Integrating green space doesn鈥檛 have to be difficult. Someone just has to lead the charge.

鈥淭he direct integration of nature into buildings in a substantive way makes quite a difference,鈥� Wolf says. 鈥淏iophilic design 鈥� is an intentional effort to integrate nature into the places where people work, learn, and live.鈥�

Nor does it have to be cost-prohibitive. “With any innovation, the early adopters pay more. Once it鈥檚 more broadly accepted 鈥� best practices emerge,鈥� Wolf says. 鈥淵ou reach a threshold of implementation, and costs come down.鈥�

Already, cities are taking steps,聽often going beyond planting trees. Chicago; Baltimore, Maryland; Portland, Oregon; New York; and Philadelphia are all investing in green infrastructure to improve city life and reduce their carbon footprint. Internationally, cities are leading in 鈥渟mart design.鈥� In parts of Singapore, .聽In London, city planners are to save energy and lessen the harm of light pollution on human health and sleep.

Workplaces are also using green spaces to address employees鈥� health and well-being. Research shows that and promote nature-oriented activities see reduced absenteeism, higher productivity, and better problem-solving in their employees. For these cities and workplaces, investing in green infrastructure has a clear cost benefit.

Now, greater attention must be directed to low-income communities to address racial and economic disparity鈥攖he 鈥�.鈥� California has a number of community-level efforts. The Little Green Fingers initiative in Los Angeles promotes urban parks and gardens in low-income areas and communities of color. In Sacramento, the Ubuntu Green project helps convert unused land into urban farms and gardens in low-income communities. And the Oakland Parks and Recreation department is working with the Oakland Climate Action Coalition and the Oakland Food Policy Council to preserve green space amid gentrification.

Houseplants bring nature inside

People living without sufficient access to green space, particularly those living with anxiety, depression, or ADHD, might also benefit from bringing nature into their homes.

无码视频 robust research in environmental psychology needs to be done to tease apart the complex benefits of houseplants, but the existing literature is promising. have been shown to soothe mental fatigue, , and . Some hospital patients who underwent surgery were found to have higher pain tolerance, less anxiety, and even shorter recovery times when they could .

Indoor greenery also brings in a distinctly interactive element that outdoor natural space can鈥檛 always provide: the opportunity to grow and nurture something. Houseplants respond to our care and can pull us to slow down. They are living reminders of the importance of staying on track and not neglecting our responsibilities. They can help us maintain good habits. Research has shown that can help improve mental health by alleviating loneliness, calming stress, and restoring a sense of purpose and responsibility; for people unable to adopt a pet, houseplants may be a great lower-stakes alternative.

This has an important caveat. As Wolf points out, lonely, isolated people are more prone to problems with mental and even physical health. Indoor plants are no substitute for community-wide solutions. Wolf encourages apartment dwellers to advocate for shared outdoor green spaces. They may benefit more from establishing 鈥渓ittle sitting gardens鈥� in place of 鈥渂oring landscape materials鈥� or ensuring that green stormwater infrastructure is designed 鈥渟o it becomes a people space, as well,鈥� she says.

Ultimately, we benefit most by incorporating interactive green space at every level of city life鈥攆or individuals, cities, and everything in between.

I look, with cautious optimism, to a future full of trees.
