Ten minutes of walking: what it does for your mood and your ideas

We often think of physical activity as an ambitious project: joining a gym, running three times a week, training for a fitness goal. So we push it off until next month. And yet, when you look at the data on mood and ideas, plain old walking already has a lot to offer.

Less than the guidelines, and already an effect

In 2022, a University of Cambridge team led by Matthew Pearce published a meta-analysis in JAMA Psychiatry on the link between physical activity and depression. It pooled 15 follow-up studies, more than 191,000 participants and more than two million person-years of observation.

The results are encouraging:

• Adults who reached half the recommended amount of activity had an 18% lower risk of depression than inactive people.
• Those who reached the recommended amount, equivalent to about 2 hours 30 minutes of brisk walking per week, had a 25% lower risk.
• Beyond that, the additional benefit was limited.

The authors estimate that if the least active adults had met the guidelines, about one in nine cases of depression could have been prevented.

Two honest caveats. First, these are observational studies: they show a strong, consistent association, not absolute proof of cause and effect. Second, walking is no substitute for treatment if you're dealing with depression. But the main message is clear: you don't need to be athletic to benefit. Half the guidelines works out to about 1 hour 15 minutes of brisk walking per week, or roughly ten minutes a day.

Walk to think better

The other benefit of walking has to do with ideas. In 2014, Marily Oppezzo and Daniel Schwartz of Stanford University published four experiments on walking and creativity. Participants were asked, for example, to come up with as many original uses as possible for an everyday object.

Depending on the experiment, between 81% and 100% of participants came up with more creative answers while walking than while sitting. The effect held whether people walked on a treadmill indoors or outside, and it lingered for a while when participants sat back down after walking.

So if you're stuck on a problem, a presentation to put together or a decision to make, a short walk can help you generate ideas. You can sort through them afterward, sitting down.

Fitting walks into a busy day

The goal isn't to find a free hour, but to transform moments that already exist. Here's how:

1. Choose a daily cue. After lunch, when you leave work, after dropping off the kids. A moment that comes around every day makes the habit easier to keep.
2. Start with 10 minutes. Over a week, that gets you close to the level associated with an 18% lower risk of depression in Pearce's study.
3. Walk at a good clip. The “brisk walking” in the guidelines is a pace where you can still talk but can't really sing.
4. Turn a call into a walk. A phone check-in with no screen to share can happen outside.
5. Use walking to think. Before tackling a creative task, head out with a question in mind, and jot down your ideas when you get back.
6. Walk with someone. A set date with a coworker, a neighbor or a friend makes it harder to back out, and the conversation makes the time fly by without you noticing.

When motivation runs low

On rainy or tired days, it doesn't have to be “all or nothing.” A minimal version counts: five minutes around the block, taking the stairs instead of the elevator, getting off one stop early. The idea is to keep the thread going from one day to the next, not to nail a perfect session.

And if you're getting back into it after a long period of inactivity or with a health issue, ask your doctor for advice on adjusting the pace.

With ForgeMe

You can create a “10-minute walk” ritual tied to a specific moment in your day, with a reminder so you don't forget. The ritual counts how many times in a row you've done it, and the journal lets you jot down the ideas that came to you along the way or your mood when you got back.
