10-Minute Exercise Cuts Depression
New research in *Nature Human Behaviour* shows that a single 10-minute online exercise can measurably reduce depression, with benefits lasting a month. The intervention can be completed at home and is being promoted as a simple, accessible mental health tool.
The study, one of the largest of its kind, involved 7,505 American adults experiencing symptoms of depression. Participants were randomly assigned to one of 12 brief, self-guided online interventions or a control group that learned about trout. The interventions were crowdsourced from 66 proposals by scientists, mental health app developers, and YouTubers in response to a 2024 social media query by the research team. The submissions ranged from science-backed psychotherapeutic approaches to novel ideas, like one that used a generative AI-based writing exercise and another that repurposed an inspirational Thai Life Insurance advertisement. While nearly all the 10-minute exercises left users feeling more hopeful immediately, only two showed a significant reduction in depression symptoms one month later: "Interactive Cognitive Reappraisal" and "Finding Focus." These exercises involved reframing negative thoughts and focusing on goals and motivation. On average, the two most effective interventions resulted in a 4% greater reduction in depressive symptoms on a standard measure compared to the control group after one month. The lead author of the paper, Benjamin Kaveladze of Dartmouth College, noted that while small, these gains can have a real impact due to the free and accessible nature of the programs. This research is part of a growing field exploring "single-session interventions" (SSIs) for mental health. Previous meta-analyses have also shown that SSIs can significantly reduce mental health issues like depression and anxiety in both youth and adults. Researchers are continuing to study these brief interventions in various settings, including on social media, in schools, and for individuals on therapy waitlists. Collaborators are also exploring the use of AI to create more personalized and engaging single-session interventions.
