Waking the Tiger: Healing Trauma is a self-help book by American therapist Peter A. Levine and Ann Frederick published in 1997.

Peter Levine argues in the book that it is through action instead of talking that people can assist others who are struggling with psychological trauma.

He concluded without evidence that Nancy's panic attacks were caused by the "frozen residue of 'energy'" that remained stuck in her, not from the traumatic experience.

[3] Ruth P. Newton, a professor at the University of California, San Diego, wrote a mixed review of the book in the journal Psychosomatic Medicine.

But Newton found that "the theory and case material are entangled by a self-help format that weakens his presentation and jeopardizes the overall organization of the book".

[2] Newton strongly criticized the book's self-help therapy activities that improperly claim to help readers to overcome their frightening experiences, writing, "I shudder to imagine a patient or client who is drawn to self-help books that will heal secret traumas alone in his or her living room with an exercise that asks them to ' pretend you are in an airplane flying at 30,000 feet… [when] you suddenly hear a loud explosion…followed by complete silence'.

"[2] John Marzillier for British Psychological Society wrote that "The psychologist Peter Levine is a major figure in the trauma field.

[1] In Psychology Today, Cheryl Eckl called Waking the Tiger a "seminal book" in which Levine tells readers "we can learn much about trauma from observing animals in the wild".
