"The Catharsis Lie - Why letting it all out poisons your brain" attacks the popular therapeutic idea that we need to "vent" our anger to feel better. Modern neuroscience reveals that venting-punching a pillow or screaming-doesn't release anger; it rehearses it. Every time we vent, we strengthen the neural pathways associated with aggression, making us angrier in the future. Author Sarah Fields explains the failure of the "hydraulic model" of emotions. She offers evidence-based alternatives like cognitive reappraisal and physiological cooling (distraction). The book argues that true emotional processing requires reflection, not explosion. Readers will learn to stop feeding the fire of their rage. "The Catharsis Lie" provides a roadmap for actually resolving negative emotions rather than just amplifying them under the guise of "letting off steam."
