To manage stress effectively during UPSC preparation, candidates can employ techniques such as mindfulness meditation, scheduled breaks, and regular physical activity. Mindfulness helps in reducing anxiety by promoting focus on the present moment, while taking structured breaks prevents burnout during extensive study sessions. Engaging in physical activities, such as exercise or yoga, can also release endorphins and enhance overall mood. Additionally, creating a support network of peers can provide emotional comfort during challenging times, aiding aspirants to cope with stress more effectively.
