Struggling with negative thoughts? Regular exercise can help reduce them
If you've ever been trapped in a cycle of worry or obsessive rumination, here's something promising: A new study published in the medical journal PLOS ONE titled ' Does physical activity-based intervention decrease repetitive negative thinking? A systematic review' suggests that regular physical activity can significantly reduce repetitive negative thinking (RNT), the kind that fuels anxiety and other mental health disorders. But there's a catch: it works best when sustained and combined with psychological training. Researchers from China, South Korea and Poland reviewed 19 studies involving over 1,000 participants and found that physical activity-based interventions, especially those involving aerobic and resistance exercises or mindfulness practices like yoga, could reduce worry and rumination. What is repetitive negative thinking and why does it matter? Repetitive negative thinking (RNT) is a mental loop where your brain keeps revisiting the same worries or regrets, often in a way that feels uncontrollable. It includes two common forms: rumination (dwelling on the past) and worry (anxiety about the future). These patterns are incredibly hard to break. According to Cleveland Clinic, an American nonprofit academic medical center based in Ohio, RNT can be a symptom of various mental health conditions like anxiety, depression, obsessive-compulsive disorder (OCD), or post-traumatic stress disorder (PTSD). Can physical activity help reduce negative thoughts? Yes, but with some nuances. The study found that moderate-to-high intensity physical activity, done regularly (30–60 minutes per session, 3–5 times a week), can significantly reduce both rumination and worry. However, the best outcomes were seen when physical activity was combined with psychological interventions, like mindfulness or cognitive training. Think of it as mental fitness, it builds up over time, just like muscle strength. Which types of exercise work best? According to the study, a mix of aerobic activities (like running or cycling), resistance training, and mind-body practices (like yoga or tai chi) showed the strongest results. Programs that blended both physical and psychological components had the greatest impact on reducing RNT. Who benefits the most from exercise-based interventions? The study revealed that people who were already dealing with clinical depression, anxiety, or chronic stress experienced more significant improvements than healthy individuals. So if you're struggling, this approach may be effective for you. How does exercise influence the brain to reduce negative thinking? Several mechanisms are at play, the study shows: Physiological: Exercise boosts endorphins, reduces cortisol, and improves brain function and neuroplasticity. Psychological: It improves cognitive control and helps regulate emotions. Social: Group activities promote connection, which helps reduce stress and negativity. What's the ideal for mental health through movement? According to the study, the sweet spot for mental relief is: Moderate-to-high intensity workouts 30–60 minutes per session 3–5 times a week At least 8–12 weeks of consistency Combine with mindfulness, meditation, or therapy-based training Should you start exercising to tame your mind? Absolutely. Whether it's brisk walking, dance, gym workouts, or yoga, moving your body regularly can quiet your mind. If you are struggling with overthinking, pairing exercise with mindfulness or therapy could be your best strategy yet. For more health updates, follow #HealthWithBS
