Practices contributing to mental well-being during stressful UPSC exam preparation include time management, regular exercise, and mindfulness techniques. Establishing a study schedule reduces anxiety by creating a sense of control. Physical activity enhances mood and cognitive function, while meditation or yoga fosters relaxation and focus. Additionally, maintaining a healthy social life and seeking support from friends or family can alleviate feelings of isolation. Engaging in hobbies or creative activities serves as a counterbalance to study pressures, aiding in stress reduction and improving overall mental health during preparation.
