Rumination is a concept in psychology that refers to the tendency to repetitively dwell on negative thoughts, feelings, and experiences. It is often associated with depression and anxiety, as individuals who ruminate often struggle to break free from negative thought patterns and emotions. Researchers have studied rumination to understand its impact on mental health and well-being, as well as how it may contribute to the development and maintenance of mood disorders. They have also investigated strategies and interventions that can help individuals break the cycle of rumination and reduce its harmful effects on mental health. Overall, research on rumination aims to shed light on the mechanisms underlying this cognitive process and identify effective ways to prevent or mitigate its negative consequences.
