I happened to find this interesting quote when reading about some high peak mountain climbers who faced traumatic, life threatening situations.
"While retelling such stories might bring up potentially distressing memories, Susan Pease Banitt (author of 'The Trauma Toolkit: Healing PTSD From the Inside Out') thinks that it could also have a beneficial effect. 'Disclosure promotes physical health and well-being. It does not seem to matter whether the traumas are told in therapy, among friends, or in writing; what does make a difference is the telling,' she says."
