exercise: the best mood medicine (podcast)

Growing up, I was a kid who hid in the back corner during gym — because dodgeballs are hard and kids are mean. I never developed a sense of myself as athletic, and mostly didn’t miss it.

Instead, I found my physicality by carrying life essentials on my back for four days on a backpacking trail. It was life altering — but somewhat location dependent.

Several years ago, I hit a personal low. I had tried pretty much all the things, but wasn’t feeling any better. After being strongly advised by a non-medical friend to consider pharmaceutical medications, a Facebook post from a doctor friend jumped out at me: Weight-bearing improves mood.

So I tried it. And it made a huge difference.

Research and clinical experience have long supported exercise as a treatment for depression and anxiety. The side effects of exercise, properly applied, are increased strength, improved blood sugar balance, better immune function and more.

(Note that I don’t tout weight loss here. Not everyone loses weight, and not everyone needs to. Overall health should be the goal, with weight optimization a possible secondary side effect.)

When it comes to depression, research shows that while medications may work faster, exercise is equally effective after 16 weeks and better than drugs after 10 months. And it doesn’t take much: Just 20 minutes three times a week of moderate-intensity exercise makes a significant difference. (PMID: 15361924.)

The same pattern holds for anxiety. Even a single round of resistance exercise can lower anxiety significantly. (PMID: 25071694)

My patients will attest to this experience. Many of them start exercising and find the stressors that would stop their lives cold no longer affect them nearly as strongly. It’s been a lifesaver for them, as it has been for me.

I mention my story because it’s not unique: Many of us have traumas and resistance around athleticism, gyms and “exercise” in general. You don’t have to want to be an athlete to get these benefits. You just need to do the things.

I started going to the gym with the idea that it was something I had to do regardless of whether I found a strong community or even liked the activity. It was a prescription. In the end, it surprised me with both community and an activity I enjoy. I’m still no athlete, but having exercise as a tool in times of stress is a huge help.

The podcast below is one I did two years ago with Michael Skogg, the owner of Skogg Gym in Portland. (The gym is now virtual.) In it I review the science behind exercise as a treatment for depression and anxiety.

I hope you find the podcast both interesting and useful. If so, please share it with folks who could use the information and inspiration.
