Here is a brief article recently published on MedScape, a doctor's news and news aggregating site. I thought it might be of interest to folks on ExRx, since most of us are oriented to weight training, which is almost always done indoors.

Rx: Exercise Daily -- Outdoors. Doctor's Orders
Prescribing Nature Therapy
John La Puma, MD|September 12, 2016
Slow Uptake of Exercise Prescriptions

With dazzling Olympic feats on display all summer, too many of my patients are still literally immobilized. Medically, sitting too long shuts off the enzyme lipoprotein lipase.

In people who are sedentary, the enzyme doesn't break down fat to create energy, like it should. But medical prescription for exercise has lagged even the slowest runner. Why?

Some reasons are time, training, and money. Time especially is a scarce commodity: The average clinician visit lasts just 20 minutes.[1] Fitness is a shamefully small part of medical training. And as doctors, we don't get paid for discussing exercise, let alone monitoring a prescription and assessing the response.

Plus, we ourselves are pressed: 40% of US primary care physicians and 36% of US medical students do not meet the 2008 federal physical activity guidelines.[2]

There are also political reasons. The well-intentioned Exercise Is Medicine (EIM) movement has Coca-Cola as a founding funder. There are disagreements about who can and should give exercise advice to patients, and about the medicalization of fitness.

Finally, there are practical reasons. Clinicians find it difficult to persuade patients that exercise is more effective than medication for any number of conditions, including stroke recovery, diabetes prevention, and treatment of low back pain.[3] Regular exercise reduces the risk for recurrent breast cancer by approximately 50%.[4]


Clinicians can speak with patients and families about fitness in inspiring, life-changing ways.

Given all these reasons, it's easy to see why fitness prescriptions are seldom more than an afterthought. Yet even without formally prescribing the frequency, intensity, time, and type of exercise, clinicians can speak with patients and families about fitness in inspiring, life-changing ways.

Because clinicians have a secret weapon to use that most people don't even know about—location. Exercising in nature (in sight of and preferably near water or greenery, whether a deserted beach or an urban park) is better.

Why Location?

Walking city streets and the office itself can be harder on your health than you think. In both environments, your attention is demanded and directed—sometimes by digital interruptions, sometimes by vehicles, toxins, or duties. In nature, your attention is drawn, not pushed, to a variety of often unexpected but not unpleasant sounds, colors, aromas, textures, and forms.

A recent Stanford study[5] of nature therapy showed significantly reduced rumination after a 90-minute walk in nature, compared with a 90-minute walk through an urban environment. On MRI, "nature walkers" showed lower activity in an area of the brain linked to risk for mental illness, the subgenual prefrontal cortex, compared with "urban walkers."

In other words, nature offers a sense of something bigger than ourselves on which to focus. MRIs show the way the brain changes when that sense occurs to us.

Exercising in nature may improve a person's immune system by enriching the diversity in the microbiota. Microbiota buffer the immune system against chronic stress-related disease.[6] They appear to act as a hormone-producing organ, not simply a collection of beneficial bacteria. Microbiota are sensitive and responsive to physical environmental changes as well as dietary ones. So, exercise in nature may favorably boost microbiota.

And finally, exercise in nature is clinically preferred and calming. A Norwegian study[7] showed that exercise in nature and in view of nature improves both mood and diastolic blood pressure vs exercise without nature.

Just 5 Minutes!

A Chinese study[8] showed higher energy levels, and lower levels of interleukin-6 and tumor necrosis factor (both markers of inflammation), in a forest walking group compared with an urban exercising group. A British study[9] showed significantly improved mood and self-esteem with "green" exercise, with the largest benefits from 5-minute engagements. Five minutes!

Of course, there are areas in our country and world in which it is dangerous to walk, never mind exercise. It may not be as easy to generate sweat and intensity with outdoor exercise as it is with indoor exercise. It may be stormy, or baking hot, or otherwise harsh outside, and the cool recesses of one's own bedroom or the gym may be just perfect for you today.

And with the 2013 total cost of inactivity estimated at $24.7 billion for the United States, and with the public sector bearing almost one half of that expense, any exercise anywhere is better than none.[10]

Yet physicians have a therapeutic tool few others in our culture wield—a prescription pad—and we have every patient's attention, at least for a few minutes. Patients try harder when doctors advise them about fitness. Overweight patients are almost five times more likely to exercise if their doctors counsel them to do so than if doctors do not. Groups like the National ParkRx Initiative already know this.

Exercising in nature is more effective, more therapeutic, and cheaper than exercising indoors without nature in sight. It costs almost nothing to ask, "Been outside yet today?" and prescribe a specific exercise in nature daily with goals—say, "Walk in a nearby park for 20 minutes with your phone off, and write down your [blood pressure, pulse, mood, and/or stress level] before and after." It might be just what the doctor ordered.

I just noticed that Doc double tapped the paste so it was posted twice. I've fixed it. It doesn't look so ominous now.
