Best practices for maintaining a healthy lifestyle during UPSC preparation include a balanced routine of physical activity, proper nutrition, and adequate rest. Engaging in regular exercise not only boosts energy levels but also enhances mental clarity, essential for effective studying. A diet rich in nutrients supports cognitive function, while minimization of caffeine and junk food contributes to overall well-being. Additionally, setting aside time for relaxation through mindfulness or hobbies helps manage stress, which is critical given the pressures of UPSC preparation. Prioritizing health ultimately improves focus and retention.
