Definition of Shinkeishitsu

Shinkeishitsu is a Japanese term that translates to “nervousness” or “neurotic temperament” in English. It is a psychological concept used to describe a distinct personality type characterized by anxiety, sensitivity, and emotional instability.


Individuals with Shinkeishitsu often experience a wide range of symptoms, including:

  • Excessive worrying and overthinking
  • Frequent mood swings
  • Increased sensitivity to criticism or rejection
  • Perfectionism and high self-imposed standards
  • Sleep disturbances, such as insomnia
  • Physical symptoms like headaches or stomachaches


The exact causes of Shinkeishitsu are not fully understood, but several factors may contribute to its development:

  • Genetics: Some individuals may have an inherited predisposition to neuroticism.
  • Environmental factors: Traumatic experiences or a stressful upbringing can increase the likelihood of developing Shinkeishitsu.
  • Chemical imbalances: Neurotransmitters in the brain, such as serotonin, may play a role in the manifestation of neurotic temperament.


Shinkeishitsu can be treated through various therapeutic approaches, including:

  • Cognitive-Behavioral Therapy (CBT): A type of psychotherapy that aims to identify and modify negative thought patterns and behaviors.
  • Mindfulness-Based Stress Reduction (MBSR): Techniques that promote awareness of the present moment to reduce anxiety and stress.
  • Medication: In some cases, doctors may prescribe anti-anxiety or antidepressant medications to alleviate symptoms.
  • Lifestyle changes: Adopting a healthy lifestyle with regular exercise, sufficient sleep, and stress management techniques can also be beneficial.

It is important to note that Shinkeishitsu is a complex psychological construct, and seeking professional help from a qualified mental health practitioner is recommended for accurate diagnosis and appropriate treatment.
