My whole adult life I’ve suffered from SAD (seasonal affective disorder). Years ago I got a light-therapy light, and found that I used it quite reflexively: It would pretty much stay off all summer and early fall, then one day in mid-October or so I’d turn it on without even thinking about it. Only later would I realize, “Oh, yeah. I needed that.”

This year I didn’t have the urge to turn the light on until yesterday, which is several weeks later than typical in recent years.

This morning, while out walking the dog, I realized why it was so much later: I’m out walking the dog close to sunrise nearly ever day.

And, as everyone knows (if they think about it), the best light-therapy light is the sun.

Highly recommended: Get outdoors while the sun is still low in the sky. Get yourself some light, along with some vitamin N (nature), and some outdorphins.,\

I have always resisted driving places to get exercise. I do it, to spend time at cool outdoor (and even indoor) places, but each time I have to get over thinking, “But I could just run/walk/whatever right here and not have to drive at all!”

I think I’m over it. Post-pandemic I’m going to be a lot more willing to drive someplace just to walk or run on a trail.

Jackie attended the annual Illinois Master Naturalist’s conference last week, and came away with any number of interesting tidbits, but one in particular stuck with me: Forest bathing is like ergonomics.

Both Jackie and I have had our understanding of ergonomics informed by Katy Bowman, who points out:

Modern ergonomics is not the scientific pursuit of what is best for the human body, but the scientific pursuit of how the human body can be positioned (in one position, for eight or more hours at a time) for the purpose of returning to work the next day, and then the next and the next and the next.

Don’t Just Sit There by Katy Bowman; excerpt.

What Jackie learned at her conference was that the Japanese concept of forest bathing (shinrin-yoku) has roots in the same idea. When Japanese salarymen started dying from overwork, a lack of exposure to nature was put forward as a partial explanation.

If the problem is a lack of exposure to nature, then immersing yourself in nature is an obvious solution. But, of course, actually immersing yourself in nature would take too much time out of the workday. Hence the research into forest bathing is all about finding the minimum effective dose. There is little or no research into figuring out the optimum time for humans to spend in nature.

Keep that in mind when you read yet another article about how just looking at a forest scene for 20 minutes reduces salivary cortisol 13.4%, or walking in the woods for just 40 minutes improves mood and boosts feelings of health and robustness.

I’m not so much interested in the answer to the question, “What’s the least number of minutes I can spend in nature and not die early from overwork?”

I’m more interested in questions like:

  • If I go for a walk in the prairie, is that as good as going for a walk in the woods? Do I get added benefits if I divide my time between them?
  • Is doing my workout under a tree in a nicely mowed lawn as good as doing it in the woods?
  • Is running past a cornfield or soybean field nearly as good as running down a forest path? How about running past a row of osage orange trees? A suburban lawn? Between two suburban lawns on the other sides of 6-foot privacy fences?
  • If I can’t get to an actual natural area, how should I choose among possibilities like a park, an arboretum, a formal garden, a managed forest, or an unmanaged thicket? How do various water features (lake, stream, creek, natural pond, detention pond, drainage ditch, etc.) affect the benefits?
  • Is just sitting on a concrete patio outdoors better than sitting indoors?

I have my own tentative answers to many of these questions, but very little data.
