Educate clients about deep breathing, progressive muscle relaxation, and imagery using the Relaxation Techniques info sheet. This printout includes a brief description of the fight-or-flight response and step-by-step instructions on how to use each relaxation technique.
We suggest practicing each of these techniques in session and providing this handout as a take-home reminder of the skills your client has learned. Ask them to practice at least one of these skills every day.
