How Nature Heals Us
New evidence that natural beauty, even in small doses, reduces stress
November-December 2003

Can contact with nature relieve anxiety and stress, aid healing, and increase concentration? It appears that it can, even when “contact” is defined in the loosest way. Some researchers now suggest that passive contact with nature, like looking at trees from a car, can be as therapeutic as a walk in the woods. It appears that nature can really provide nurture—for the young and old, healthy and sick, alike.

Here's why.
“We have two kinds of attention,” says Andrea Faber Taylor, an environmental psychologist and postdoctoral research associate at the University of Illinois. The first is the “directed attention” we call on for tasks that require focus, like driving or doing our taxes. Directed attention tends to be tiring, however, and fatigue affects our ability to make good decisions and control destructive impulses. The best way to restore directed attention is to give it a rest by shifting to the second type, “involuntary attention,” which we display when we watch a fire or meditate, for instance. Looking at nature is another activity that gives our directed attention a chance to recover.
For example, Roger Ulrich and his colleagues at Texas A&M University found that people who commuted along scenic roads recovered more quickly from stressful driving conditions than those who saw billboards, buildings, and parking lots. Ulrich also noted something he termed an “inoculation” effect: Drivers who had taken the scenic route responded more calmly to stressful situations later on. Ulrich also looked at patients recovering from gallbladder surgery. The patients who could see trees from their hospital beds needed fewer painkillers and had shorter hospital stays than those who looked out on brick walls.
So, with all our efforts to alleviate stress—from aerobics and yoga to anti-anxiety pills—lmaybe the key is as simple as a garden. In fact, even a little bit of green seems to make a big impact. Some studies suggest that a houseplant or even a picture of nature can convey similar benefits.
