Core Viewpoint - Exercise is crucial for mental health, especially in high-pressure environments, as it helps counteract the overreaction of the amygdala, alleviating stress and depression [1][2]. Group 1: Underestimated Anti-Depression Exercises - Dancing is identified as the most effective exercise for treating depression, as it combines music and movement, stimulating the brain's reward center and promoting the release of endorphins and dopamine [4][5][6]. - Badminton is highlighted for its immersive experience, providing immediate feedback and a sense of flow, which enhances long-term happiness [7][10]. - Yoga promotes mental and physical balance, reduces stress, and fosters a harmonious connection between body, mind, and spirit [11]. Group 2: Additional Effective Exercises - Tai Chi and Ba Duan Jin are beneficial for reducing inflammation and improving mental health through low-intensity movements that can be performed anywhere [12]. - Walking and running increase the levels of endocannabinoids in the blood, which are linked to feelings of euphoria, and spending time in nature enhances overall well-being [13][14][15]. - Swimming is a low-impact exercise that minimizes stress on joints and allows for mental relaxation by disconnecting from external distractions [17][19]. - Rock climbing, referred to as bouldering therapy, helps alleviate anxiety and depression by requiring intense focus and resilience through repeated challenges [20][22][23]. Group 3: Conclusion - The key takeaway is that the specific type of exercise is less important than the act of engaging in physical activity itself, which can significantly improve emotional and physical health [24].
