This breathing technique sounds like a powerful tool to relieve depression, anxiety and stress responses – all three being diseases or disorders associated with the outcomes of (C-) PTSD (listed under so-called co-morbidities, i.e. diseases that are secondary outcomes of the primary one). I have posted about Dr. Stephen Porges’ seminal work before, concluding from the linked article that his approach and findings might have the potential to cure a person who has been suffering from PTSD and C-PTSD for a long time. As we all know and as researchers now confirm, symptoms of PTSD worsen over time as the fear-related responses get “engraved” deeper and deeper in the system with every triggering situation and every flash-back that affected individuals experience.
I personally haven’t done SK&P yet, but I did some holothropic breathing for a while. The effects of an hour of non-stop breathing at varying pace and the ensuing rest and relaxation with scented candles and meditation music in a light-dimmed room and someone to talk to when needed are often described as “rebirthing”. I must admit that some powerful emotions came up – not as powerful as I know them from my own “treatments” of self-medicating with alcohol and then watching a drama movie, where trauma – or overcoming trauma – runs as a central theme of the movie. But they were powerful enough.
As far as that – admitted: questionable – approach I found myself, i.e. binge-eating, binge-drinking and watching movies that seemed to have a fair amount of potential to trigger me, I think it helped me to at least access and feel emotions I seem to have repressed forever. In other words: I wouldn’t underestimate the healing potential of a good cry – even if it borders into a breakdown lasting several hours (they did a few times, yes). After all, if we were supposed to be tough all the time, evolution probably wouldn’t have bothered to provide our species with tear glands, right? Now I’ve said it: I’m a crybaby, hahaha! 😀 But seriously: I’d deem reconnecting with bottled up emotions and for once giving yourself permission to feel them and even let them overpower you not too small a therapeutic value (might sound overbearing on my part, but I do know that I felt a good deal of relief and “inner clarity” and calmness when those crying fits were over; a few times might do, I don’t think you need to go through an entire series of re-experiencing.)
Anyway, without further ado on my part, find the article on SK&P here: The Vagus Nerve and the Healing Promise of The Sudarshan Kriya – Waking Times : Waking Times.
