Stress can significantly negatively impact UPSC exam performance, leading to decreased concentration and increased anxiety. High levels of stress may result in difficulty recalling information during the exam, affecting decision-making skills and reducing overall productivity. Additionally, long hours of studying without adequate breaks can lead to burnout, further diminishing physical and mental well-being. Therefore, managing stress through regular exercise, mindfulness practices, and adequate sleep is vital. Implementing effective time management and seeking social support can also alleviate pressure, ultimately enhancing performance during the exams.
