Neuroticism, one of the Big Five personality traits, is a psychological characteristic that indicates a person's emotional stability and reactivity to stress.

Individuals with high neuroticism tend to exhibit strong emotional reactions to everyday events and frequently experience negative emotions such as anxiety, sadness, and anger. They may find it difficult to remain calm under stress and pressure, and often overreact to minor challenges and changes. Additionally, they are susceptible to experiencing significant psychological stress from everyday difficulties, which can increase the risk of long-term mental health issues.

Conversely, individuals with low neuroticism are emotionally stable and capable of handling stress and adversity calmly. They are more likely to maintain a positive outlook even in tough situations and are less prone to psychological distress.

Understanding neuroticism deeply can facilitate better stress management, emotional control, interpersonal relationships, and career choices, enabling individuals to find the most suitable approaches for various situations.
