It's only fair to share…

 Move the Blues AwayExercise for mental health. I think this is something we have touched on previously in the podcast, but it is an issue that’s worth revisiting, and in particular, some interesting new data is out. Now, you probably won’t have seen this in the mainstream media because it’s not a pill. If this were a pill, it would be on the front pages, and everybody would be hearing about it, and public health would be saying everybody should be taking it.

Data from randomized trials provide robust evidence for the benefit of exercise on symptoms.

I’m going to quote here—this is on MedPage Today—and we’ll put the link in the description. A meta-analysis of randomized trials showed that exercise reduced depression and anxiety symptoms.

Now again, most of you may be familiar, but some of you might not. A meta-analysis is not a new study; it’s a study of studies. They gather data from a whole lot of trials done over time and combine the numbers. That’s useful because many studies don’t have large sample sizes, and smaller numbers mean weaker conclusions. If you study just a few people, the findings may not apply broadly. Larger numbers generally increase usefulness and applicability—though not always.

One catch: garbage in, garbage out. The quality of the trials influences the meta-analysis. Poor-quality studies don’t become better just because they’re combined. However, more trials increase the likelihood that some useful data exists within them. Even then, one meta-analysis alone doesn’t prove anything. Findings must be repeatable.

There have been many studies showing the benefits of exercise on mental health. Group exercise appeared to be the most effective for depression, while shorter duration and lower intensity exercise was most associated with reductions in anxiety symptoms.

This isn’t surprising. Group exercise includes a social component, and loneliness is linked to depression. Being in a group creates shared experiences and conversation opportunities, which are beneficial. Over time, this can build relationships and support systems.

Shorter exercise helping anxiety is interesting, though cause and effect isn’t always certain. What we do know is that exercise triggers the release of endorphins—natural “feel-good” hormones. That’s why people often feel a “high” after activities like running.

Here’s the key point: exercise effectively reduces symptoms of depression and anxiety at levels comparable to pharmaceutical or psychological treatments, according to a large systematic review published in the British Journal of Sports Medicine.

Aerobic exercise had the strongest impact. Group and supervised exercise showed greater reductions in depression. While benefits were seen across all ages, the greatest effects were observed in adults aged 18 to 30 and post-natal women.

That doesn’t mean others don’t benefit—everyone does, just to varying degrees.

The key message is that exercise can play an important role in managing depression and anxiety. While some suggest tailored programs, the most important thing is simply getting started and staying consistent. The best exercise is the one you enjoy—because that’s the one you’ll stick with.

There’s no point recommending something a person dislikes. Whether it’s running, cycling, gym classes, or something else—choose what works for you.

Keep it simple. Walking is one of the easiest forms of exercise. It requires no special equipment and can be done almost anywhere. You can go for a walk during lunch breaks or throughout your day. It’s accessible, affordable, and effective.

Exercise may not completely replace medication or therapy, but the fact that its effects are comparable is significant.

Billions are spent worldwide on mental health, yet overall outcomes are not improving. In fact, things may be getting worse. That raises the question: do we need to rethink our approach?

Exercise has no harmful side effects like medications can, and it doesn’t require sitting in therapy sessions, which may not suit everyone.

Research has shown that within three weeks, people who start regular exercise can see a 36–40% reduction in depression and anxiety symptoms.

This isn’t new information. Exercise isn’t a magic cure, but it’s a powerful tool—especially for stress management. Since stress often leads to anxiety and depression, exercise is also valuable as prevention.

Despite this, you probably won’t see it widely promoted. It’s too simple, not profitable, and doesn’t attract attention like medications do.

But simple is good.

Exercise isn’t the only answer—but it is an important one.

Regular exercise of any kind is beneficial for both physical and mental health. Do what you enjoy. Do it consistently. If you haven’t started, begin at a level that suits you. If you have health concerns, consult your doctor first.

Don’t overdo it on day one. Start small and build gradually.

The key is:

  1. Start
  2. Stay consistent

The benefits are clear and many.
