Short Workouts Reduce Depression Symptoms for Weeks, Study Finds

A recent study reveals that just ten minutes of physical activity can significantly reduce symptoms of depression, with benefits that persist for up to a month. These findings highlight the lasting impact of brief exercise on mental health.

A New Approach: Ten-Minute Interventions for Depression

In a world where over 330 million people are affected by depression each year, according to the World Health Organization (WHO), the search for accessible and effective solutions remains urgent. In 2024, researchers at Dartmouth College took an unconventional step. They posed a single question online: “What would you say if you had ten minutes with 500 people living with depression?” The response was overwhelming. Not only scientists, but also mental health app developers and influencers from across the globe contributed their ideas.

From Global Call to Groundbreaking Trials

The research team received sixty-six proposals and narrowed these down to twelve of the most promising concepts. These were tested in one of the largest ever randomized controlled trials on brief mental health interventions. Approaches ranged from established psychotherapeutic techniques to cutting-edge technologies like AI-assisted expressive writing, as well as creative methods such as sharing a viral Thai public service announcement about community support.

More than 7,500 American adults participated in this study. Each completed a self-guided exercise—none lasting longer than ten minutes—or a control activity involving learning about trout. Researchers measured participants’ feelings immediately after the session and again one month later.

Measurable Impact and Enduring Hope

Almost all interventions immediately boosted participants’ sense of hope and motivation to act. However, when it came to sustained relief from depressive symptoms, only two programs—Interactive Cognitive Reappraisal and Finding Focus—stood out. One month later, these digital tools achieved a modest but statistically significant additional reduction (about four percent more) in depressive symptoms compared to the control group.

The advantages of these approaches are hard to ignore:

• Simplicity: Each session lasts less than ten minutes.
• Efficacy: Two techniques proved effective over time.
• Universal reach: Free, online resources available for everyone.

The Road Ahead: Scaling Up Digital Support

While these digital interventions are not intended as substitutes for professional therapy, they hold particular promise for those unable to access traditional care or waiting for their first appointment. Initiatives like those from the team behind Koko, which already offers several free short exercises tailored for different psychological needs, exemplify this new wave of support.

Looking forward, researchers are exploring how best to integrate these tools into platforms such as social networks and schools—and how artificial intelligence might further personalize assistance. Even just ten minutes spent on scientifically-backed exercises could mark an important step towards better mental health for many people worldwide.
