2026 April 28 Exercise yourself happy!

Hi, this is Jim Cranston from 7Every Minute and 7EveryMinute.com — the podcast and website about reimagining your life. Thanks for joining me today to talk about how your brain, your body, and all those pieces play together to actually control your mood. Let's get started. If you like what you hear, please leave a like, subscribe, tell your friends, and send me a message.

This week I want to share something a little more personal — an example from my past few months — about how the body and the brain interact in ways that people often underestimate. People generally assume that if your brain is working well, your body will follow. But what we often forget is that your brain really needs your body to be in reasonably good condition to function effectively. It doesn't mean you have to be a strongman. It just means being in reasonable working order, because there are a lot of things the brain needs that the body has to produce and send up to it. That's the theme for tonight.

Last week we talked about some of the inner workings of the mind, which was a pretty complex topic even when simplified. Tonight I want to approach the mind from a different angle — the mind-body connection — and how closely they're really linked. It's also related to some things I've been keeping in mind when I'm tempted to be disappointed with certain situations.

Yesterday I had a physical exam — not one I exactly asked for. A few weeks ago I went in just to make sure a lingering sniffle wasn't anything serious, and somehow that appointment turned into a full exam. My doctor and I have worked together for a long time, and he knows I look after my health, so he was a little surprised to see me again so soon. The practice had just been sold, and I think the push for a full general physical was more of a revenue-generating move by the scheduling department than anything else. Regardless, we went through everything, and today I got a full panel of bloodwork, which is never really a bad idea.

So why do I mention all this? Because I'm confident that I'm in pretty good health — not because I just happen to feel fine, but because I actively pay attention. If I have trouble running, or an ache that persists more than a few days, or something just seems off, I don't brush it off with "I guess I'm getting old." I had a doctor once who used to say that to an old friend of mine — "How old are you now?" — and it would infuriate her. She was absolutely right to be irritated. Age is not a diagnosis.

I'm not at the gym every day. I do a small amount of exercise at home, and that's it. I don't obsess over my health, but I don't take it for granted either. That slight, consistent effort pays big dividends — both for my body and for my attitude. When I notice I've put on some weight, I review my eating habits to see where I might have been cutting corners too often. That doesn't mean going on a diet. It means paying a little more attention to what I'm actually eating. In my case, I'd gotten a little too friendly with salt-free corn chips, which I absolutely love. And I know what you're thinking — salt-free corn chips? It's an acquired taste. But once you try them, you'll never go back. You start to realize the salt is just there to cover up bad ingredients. But that's a different story.

The point is, it wasn't some major overhaul. It was just being a bit more mindful about food.

Similarly, about six or seven months ago, I was jogging across the entrance lane to a local shopping area — darting between traffic — and I noticed my back hurt. I knew exactly why: I'd been sitting at a desk for too long, for months, doing stressful work. So I committed to actually responding when my hourly exercise timer went off. I have a simple little recording that says, "Stop what you're doing, get up and exercise." I'd gotten really lazy about honoring it — telling myself I'd do it next time, or in five minutes, and then getting absorbed in what I was doing and never following through.

The change I made was tiny: when the timer goes off, I get up and do something. Even just three minutes of stretching. Often I'll pick up some weights, or hang from the chin-up bar I keep in one of the doorways. Any of those things make a huge difference in how your body feels at the end of the day. And at the same time, I started incorporating short running bursts into my dog walks — nothing dramatic. Maybe running uphill for 30 or 60 seconds just to get my body used to being active again. I say uphill because I actually find that easier than downhill. And when you're out walking, it's one or the other.

Today was a gorgeous day here — truly beautiful. We went out for a longer walk and I ended up running for more of it. We took the more difficult route, which meant running up a steep embankment and then a longer run up a slope on the way back. And here's where the mental side comes in.

By the time we were nearly home, I felt great. I had forgotten just how much good happens to your mind when your body starts to exert itself — even just a little. It doesn't have to be hard. My actual exercise routine is probably shorter than this podcast. But when you push your body to whatever degree you're capable of, it responds with chemical changes that the brain and nervous system receive as genuinely good news.

According to Oregon Health News, exercise releases neurotransmitters and hormones like endorphins, dopamine, serotonin, norepinephrine, and BDNF. These chemicals improve mood, reduce stress and anxiety, enhance cognition, and promote the growth of new neurons. The key effects include what's known as runner's high, reduced pain perception, better stress regulation, and enhanced focus. Your body and your mind are simply happier when you're actually doing something.

And that mattered later in the day. While I was writing this podcast, I got distracted and boiled my tea completely dry on the stove — because I didn't set a timer. The smoke detector kindly reminded me I'd made a mistake, which is why this episode started a little late. Now, normally, I would have beaten myself up over something like that. I know I should set a timer. I know I'm just being stubborn when I don't. But instead, I felt grateful. Grateful that the smoke detector did its job. Grateful that my trusty stainless Revere Ware pot — thirty or forty years old — survived yet another ordeal. This wasn't its first time. And I didn't for a second take it as some sign of mental decline. It was just my own stubbornness, plain and simple.

So here's the thread: by gradually increasing my physical activity over six or eight months — through the tiniest of steps — combined with some minor dietary adjustments over a few weeks, I was able to be more comfortably active. That physical shift then boosted my brain's environment in ways that made me more confident and better able to handle an unexpected stressor completely in stride.

This isn't me boasting. This is simply a reminder that consistent effort, no matter how small — even toward a distant goal — can produce significant results. It helps you age more comfortably and more confidently.

And as a side note — I may have accidentally acquired a taste for smoked tea, because I used the very same pot to make the cup I'm drinking right now.

But seriously, think about it: if I'd been really tired, stressed, aching, and feeling low — maybe coming off a disappointing doctor's visit — how different would my mental reaction have been? That's exactly why we keep emphasizing that small, even tiny, steps toward your goals can produce enormous changes in how you're able to live as you age.

You might be thinking, "But Jim, I'm 50, 55, 60, 65, 70 — whatever." To which I say: so what? Improvement is always available. Yes, the earlier you start, the easier it is. But you are always able to make positive choices that help your body and your brain help you enjoy a more pleasant life.

The changes don't have to be big. When I started my own revival, my running intervals were literally five or eight steps long — just enough to let my muscles begin to adapt again. We'd be walking down the street and I'd just run for a couple of steps. My back would ache a little, but I knew it wasn't serious. The next day, a couple more steps. After a few days, my back stopped hurting and I'd run a few more. Itty-bitty steps.

I didn't overhaul my eating habits either. But I did notice that having a few sugar cookies during the day would consistently nudge my weight upward. The effect of insulin release when you eat sugar is genuinely dramatic. I was gaining about a quarter pound a day on the days I had the cookies — on basically the same diet otherwise — while on the days without them, I'd work it right back off. I can't emphasize this enough: sugar is fun. I'm a serious sugar addict. And it's easy to be, because sugar is in everything these days, unless you really work hard to avoid it. But watch your sugar.

A friend of mine, by the way, is starting a course and workshop on exactly that topic. If you're interested, let me know and I'll post the link.

My point with the cookies was simple: I knew where I wanted to be. I wanted to be able to run with my dog in the mountains this summer. That was my goal, and these little tiny changes over months will likely make that possible.

Tiny steps. That's it.

So now it's your turn. What little — or big — goals have you been thinking about? What changes do you wish for in your life? This example is about physical conditioning, and I do think that's the foundation for good physical and mental health. But your goal can be absolutely anything that's truly important to you. Start there, then work backwards toward today, and ask yourself: what is the next tiny step I can take to move even one inch closer to what matters to me?

Good luck. We've talked about this before and we'll come back to it in the coming weeks. But remember — don't scare yourself out of progress by trying to do too much right from the start. The most important step is the very first one: just getting started.

That's it for tonight. No homework, because we're still in the basics. Stay positive — there are more exciting things to come.

And as always, remember: one of the best ways to care for yourself is to care for others. Please check out UKR7.com to help the people of Ukraine, and WCK.org — World Central Kitchen — which does incredible humanitarian work around the world. Local charities are always looking for help too. And even something as simple as a smile to someone you pass on the sidewalk can change their day in ways you can't even imagine. You have an amazing power within you — the power to spread happiness, to make other people feel seen.

So if you ever catch yourself thinking, "I can't do anything — there's just too much going on in the world," remember: even a smile can shift someone's attitude.
