Many people believe that to cope with depression, you need a psychotherapist, antidepressants, or at the very least a radical lifestyle change. Sounds logical, and it’s even correct. However, a new large-scale study shows that even a 10-minute exercise can reduce symptoms of depression. And, most interestingly, the effect persists even a month later! And it’s not meditation or breathing exercises — it’s much more interesting than that.
Can Depression Symptoms Be Reduced in 10 Minutes?
It all started in 2024, when a group of American researchers posed an unusual question to mental health specialists around the world:
If you had 500 people with depression and only 10 minutes of their attention, how would you use that time?
66 experts responded. Among them were scientists, mental health app developers, popular bloggers, and even students. From the 66 proposals, the team selected the 12 most promising and turned them into short self-guided exercises that could be completed online without a therapist’s help.
The range of approaches was impressive. One exercise used generative artificial intelligence for expressive writing. Another was built around a viral Thai insurance company commercial that showed how small acts of kindness fill life with meaning. A third relied on classic cognitive behavioral therapy methods adapted for self-guided completion. Each took no more than 10 minutes.
What Actually Reduces Depression Symptoms Without Therapy
According to Nature Human Behaviour, to test the effectiveness of the selected interventions, the researchers conducted one of the largest randomized controlled trials in the history of mental health psychology. More than 7,500 American adults participated, each randomly assigned to one of 12 experimental groups or to a control group.
Participants in the control group received neutral educational materials about depression — useful, but without practical exercises. The experimental groups completed one of the 12 interventions. Afterward, the scientists measured depression symptom levels: immediately after completion, one week later, and one month later.
The result? Several of the 12 exercises demonstrated a statistically significant reduction in depression symptoms that persisted even after four weeks. You might think 10 minutes is nothing. But the thing is, depression often traps a person in inaction: it seems like nothing will help until something monumental happens. This study shows the opposite — that even a tiny first step can trigger a chain of improvements.
Expressive writing is one of the oldest psychological techniques. It turns out that paired with AI, it works even better
Best Exercises for Depression
Not all 12 interventions worked equally well. The most effective ones turned out to be not abstract advice, but specific techniques with clear steps that help reframe one’s attitude toward difficulties and find meaning in everyday life.
Altruism Exercise (Helping Others)
The idea: Participants were asked to write down how they could help other people, even in small ways.
Why it worked: The idea of a connection between altruism and mood isn’t new, but here it was packaged in a simple, clearly structured format.
Advantage: Can be completed in a few minutes and requires no preparation.
Expressive Writing with AI Support
The idea: Participants described their experiences, and AI helped reformulate their thoughts in a more constructive way.
Analogy: It resembles working with cognitive distortions in psychotherapy, where the algorithm serves as a guide.
Important clarification: The authors emphasize that this is not a replacement for a therapist, but a first step (or aid) for those who are not yet ready for professional support.
IMPORTANT NOTE: The effect of the exercises was small but sustained. The scientists honestly note: 10 minutes won't cure clinical depression. However, for many people, such a small positive experience becomes the push toward further action.
Can Depression Be Treated with Exercises?
Short answer — no. Long answer — also no, but with caveats.
The study’s authors emphasize that such exercises are not intended for treating severe clinical depression. They are not a replacement for antidepressants and not an alternative to working with a psychotherapist.
But here’s what they can do: lower the barrier to entry. According to the WHO, more than 75% of people with depression in low- and middle-income countries receive no treatment at all. Even in developed countries, waiting lists for psychotherapists stretch for months. In such a situation, a free 10-minute exercise accessible from any device can become that very first step that otherwise would never have happened.
Furthermore, the results open an interesting perspective for developers of mental health apps. The market is currently flooded with products whose effectiveness no one has properly tested. This study sets a new standard: rigorous testing, large sample size, transparent methodology. If this approach becomes the norm, users will finally be able to distinguish effective tools from marketing gimmicks.
