Asking your therapist "how are you" is generally considered a polite greeting and a form of social nicety. However, in the context of a therapeutic relationship, it is important to remember that the focus of the sessions should primarily be on you and your concerns, not on the therapist's personal life or feelings.
Therapists are trained to maintain professional boundaries and to prioritize their clients' well-being during therapy sessions. They are there to provide support, guidance, and a safe space for you to explore your thoughts and emotions. It's not appropriate for a therapist to share personal information or discuss their own feelings during therapy sessions.
Asking your therapist how they are may not be harmful, but it may divert the focus away from the therapeutic process and your own needs. If you find yourself curious about your therapist's well-being or personal life, it might be helpful to discuss this curiosity within the therapy session. You can talk about any concerns or feelings that arise around the therapeutic relationship, and the therapist can help you explore and understand those feelings better.
Remember that the therapeutic relationship is a unique one, designed to be client-centered and supportive. If you have any questions or doubts about the boundaries of the therapeutic relationship or the appropriateness of certain interactions, feel free to discuss them openly with your therapist. They will be able to clarify any concerns and ensure that the therapy remains a safe and productive space for your personal growth and healing.
